ALL-NEW LEXUS LX DPL PRESS KIT
- New generation LX combines quality, reliability, durability, and off-road performance cultivated over many years with supreme on-road ride comfort
- Introduction of two new powerful and efficient petrol and diesel powertrains
- Implementation of Lexus’s next-generation design language, which harmonizes functionality and elegance
- New VIP grade with four independent seats and supreme comfort credentials
The all-new Lexus LX is the fourth generation of Lexus’ flagship SUV and first full model change in 14 years. It is rich in the qualities that represent the next chapter of Lexus, from its powerful design to new powertrains, world and Lexus-first technologies and superb performance, whether driving on city streets or tackling the harshest rough road routes.
Lexus’ commitment to maintaining the LX’s authentic SUV performance is reflected in the retention of a body-on-frame construction, but in this instance with the benefit of a robust yet lightweight new Global Architecture GA-F platform. Combined with the use of highly rigid yet light materials in the body, this has helped reduce the LX’s weight by around 200 kg – benefiting ride comfort, handling stability and fuel efficiency without compromising strength or safety.
Two new power units make their debut in the LX, a 3.5-litre twin-turbocharged V6 petrol in the LX 600 and a 3.3-litre twin-turbo V6 diesel in the LX 500d. Although smaller in capacity than the previous V8 engines, both produce more power and greater torque, delivered across a wider range of engine speeds for powerful, linear acceleration. A new 10-speed Direct Shift automatic transmission has been designed with ratios that support smooth acceleration up to high engine rpm and comfortable high-speed cruising.
Whatever the driving conditions, the LX delivers the Lexus Driving Signature, giving the driver a constant, rewarding sense of connection and control of their vehicle, which responds quickly and faithful to their intentions. An Electric Power Steering system is adopted for the first time, together with Electronically Controlled Braking, helping achieve the optimum performance on and off-road. The suspension systems have been redesigned, too, and feature both Active Height Control and Adaptive Variable Suspension for agility, stability and comfort in all driving scenarios.
The exterior design captures the latest evolution of Lexus’ design principles, here based on a concept of “Dignified Sophistication.” The powerful styling is anchored by a new interpretation of the signature Lexus grille, rendered as frameless arrangement of parallel bars that project a strong three-dimensional look and integrating the spindle shape into the vehicle’s body.
In the cabin, the driver’s space is a Lexus “Tazuna” cockpit, where the design and layout of the controls and information displays are precisely calculated for quick and easy operation with least movement of the eyes or body. Driver and passengers enjoy excellent comfort with new seat designs that ensure good body-holding, even when travelling over rough ground. The LX is available with five or seven seats – the latter with a new folding mechanism for the second and third rows that creates a vast load space with a flat floor at the touch of a button.
The LX is also available for the first time in a new VIP version. This is designed for ultimate travelling luxury, with just two large rear seats with heating, ventilation and massage functions, additional climate control features and an ottoman support for the lower legs that deploys from the front passenger seat seatback.
The quality of off-road driving performance has been taken to another level with new and improved control systems for tackling the toughest conditions, including a new underfloor viewing function to check the areas immediately around the front and rear wheels and a turn-assist braking control that helps the driver to negotiate extra-tight off-road turns. Among so many new features, the LX has kept the same wheelbase length, helping maintain its ability to tackle challenging off-road terrain.
FLAGSHIP SUV DESIGN
- New design based on the concept of “Dignified Sophistication”
- A vehicle with mature proportions that looks good on the city streets, or driving on rough roads
- Powerful interpretation of the signature Lexus spindle grille in a large, frameless arrangement of parallel bars
- Increase in vehicle width and tracks and a reduced overall height; wheelbase remains unchanged
In creating its new flagship SUV, Lexus has produced a vehicle that is as at home in the modern urban world as it is driving over rough terrain in the great outdoors. This has been achieved by applying human-centred technology, next-chapter Lexus design language and unmatched Takumi craftsmanship and focusing on refining the LX’s essential characteristics.
The guiding concept for the design programme was “Dignified Sophistication.” This inspired designers to produce a vehicle with a powerful, imposing presence and a sense of sophisticated dignity that make it a worthy flagship model of the Lexus luxury brand.
The new LX has the same 2,850 mm wheelbase as its predecessor, a conscious decision aimed at preserving the dimensions that has delivered the high level of off-road capability the model has enjoyed through successive generations. The front and rear tracks have been widened by 25 mm (to 1,675 mm), overall width has increased by 10 mm (1,990 mm) and the overall vehicle height has been brought down by 15 mm (1,895 mm), creating more balanced proportions and a more assertive appearance on the road. As a result, the model has maintained its 26˚ angle of approach, 25˚ angle of departure and 26˚ ramp-over angle.
Chief Engineer Takami Yokoo commented: “Referring to the wheelbase, we have not changed the LX’s ‘golden ratio’ (ideal wheelbase length) since its debut. If you are only considering comfort, then it’s better to have a long wheelbase. But when driving over different rough terrain, a shorter wheelbase is less likely to hit the ground.”
The frontal appearance has a wide and strongly pushed-forward look which emphasises the LX’s imposing stance. The bonnet has a distinctive concave centre section – sculpted as deeply as the aluminium press would allow. This is design with a practical purpose, to help the driver better gauge the vehicle’s position when driving on uneven ground.
The most impactful feature is the new interpretation of the signature Lexus spindle grille, presented here as a frameless unit composed of a series of floating parallel bars, creating a strong three-dimensional effect. The design seamlessly integrates the spindle shape into the vehicle’s body, generating a dynamic form that evokes powerful driving performance. It is not just about aesthetics however; the design takes into account the greater cooling requirements of the LX’s new higher output powertrains. For the same purpose, the lower corners of the bumper house large air intakes and fins in the bumper side-guide channel air into the sub-radiator.
The slim headlights house four-projector LEDs and are underscored by integrated daytime running lights and indicator lamps arranged in Lexus’ signature arrowhead design.
In side view, the silhouette displays mature proportions, which give the vehicle both strong presence in urban settings and the capability to tackle rough road conditions. The impact of the more pronounced, longer bonnet has been emphasised by pulling the front pillars back by 70 mm and the front and rear overhangs have each been increased by 10mm. This creates the impression of a taut, sporty body above a solid body and large wheels. In fact, the wheels are the largest yet used on a Lexus model, at 22 inches in diameter. Being forged rather than cast alloy, they are both more durable and lighter in weight, making a positive contribution to the LX’s driving dynamics by reducing the car’s unsprung weight.
A sharply inclined back window adds to the condensed, dynamic look, while a strong horizontal axis extends from front to rear to give the body a strongly unified appearance. Above this axis, the rear quarter pillars taper from the roof to the back window; below, the underbody kicks up from the lower edge of the rocker panels to behind the rear wheels. Across the bodywork, the surfacing features precisely aligned, complex forms that express the LX’s intrinsic sophistication and refinement.
The basic volume of the body tapers towards the rear of the car and wraps around the back to give the visual impression of a solid mass. The previous split-tailgate has been replaced by a one-piece top-hinged back door. The rear lights combine Lexus’ L-motif shape in the clusters with horizontal blade light that extends across the width of the vehicle. As on the new NX, the Lexus emblem is replaced by the LEXUS name, positioned centrally; the model name is located in the bottom right corner of the back door. The look is clean, modern and an instantly recognisable representation of Lexus’ new design direction.
The cover for the towing hitch is seamlessly integrated in the rear bumper, adding to the uncluttered design.
Lexus’ Omotenashi hospitality is witnessed in an automatic easy-closing system for the side doors and hands-free power back door operation with quicker response and operating time.
Three alloy wheel designs are available: standard 20-inch with bright-machined V-shaped twin spokes set against a dark coating; 22-inch for the luxury grade, with a contrasting combination of black and bright machined finishes; and 22-inch for the VIP model, using the same design but with a premium metallic coating applied after the machining.
LUXURIOUS, RELAXING CABIN ENVIRONMENT
- Tazuna cockpit gives the driver instant, easy access to vehicle controls and information
- Interior designed for relaxing comfort in all driving conditions
- New automatic seat folding systems for easy third row access and load space extension
- Five and seven-seat cabin arrangements, plus new four-seat VIP grade
Lexus has sought to achieve a cabin environment that is relaxing for everyone on board in all road conditions, whether on the highway or travelling off-road.
The front area is clearly defined with a driver-focused cockpit and a more open, relaxing passenger space. There is ample space in the second and third rows, while comfort and amenities are taken to an even higher level in the new four-seat VIP model.
Following its first application in the all-new NX mid-size SUV, Lexus’ new Tazuna cockpit concept is further evolved in the LX. Taking its name from a Japanese word that describes a rider’s control of their horse using the reins, the Tazuna design organises the principal controls and information displays within the driver’s immediate sight-line for easy, intuitive operation, maintaining the principle of “hands on the wheel, eyes on the road.”
The instrument panel contrasts with traditional SUV design in having a solid, horizontal form with a slim profile, giving the driver a sense of balance, particularly in rough-road driving, and giving the cabin a wide and open feel. The lower section is shaped to encompass the driver and passengers, an effect enhanced by it being upholstered and visually flowing into the door assist grips.
The design of the centre console unit projects a sense of continuity with the instrument panel and features a seamless frame that has the strong look of a single piece of metal.
The combination meter and head-up display are centred directly in the driver’s line of sight, with a 30˚ angle below the straight-ahead for easy, instant viewing. The LX’s innovative dual centre displays (further details in the Imaginative Technologies chapter below) are also ergonomically positioned. The upper 12.3-inch multimedia display is brought closer to the driver, requiring less eye movement to read, while the lower seven-inch screen is angled so there is no risk of accidental operation while adjusting the upper display.
Controls and switched are grouped into clearly defined zones according to their function, so they can be used intuitively with least eye movement or changes in posture. The principle driving controls are consolidated into just three switches and two dials on the centre cluster; the driver can engage their preferred settings for the Multi-Terrain Select, Downhill Assist Control and Drive Mode using the same mode select dial. Secondary control switches, including the parking brake, brake hold, centre differential lock, VSC OFF and vehicle height selection are set lower on the console, immediately next to the driver. Toggle switches have been introduced for adjusting the climate control system, which are easier to use when driving on uneven surfaces.
The new three-spoke 370 mm diameter steering wheel has a variable cross-section and thumb grips designed to give the driver a reassuring feel of control in all driving conditions. The steering wheel heater now provides warmth around the wheel’s full circumference. Paddle shifts are fitted as standard to give the option of manual shift changes.
The shift lever has a shift lock release button, independent from the direction of shifting operation, so the driver can quickly switch between forward and reverse, even in challenging driving conditions.
Close attention has also been paid to the position of the accelerator and brake pedals, set further apart compared to the previous model for easier operation on rough roads. A more rigid and shorter stroke accelerator pedal contributes to quicker initial response and acceleration feel.
The designers and engineers worked together to create a refined cabin appearance that respects the characteristics of the different materials used for the upholstery, trims and ornamentation. The centre console and upper instrument panel present a combination of solid metallic surfaces and leather-wrapped pads, symbolising the LX’s flagship SUV status.
Surfaces that are frequently touched, such as the assist grips, have seams with raised stitching that visually sinks into the leather, adding to the authentic quality feel. On the front seats, the stitching pattern is designed to help disperse pressure on the occupant’s body, helping reduce fatigue on long journeys.
Driving position and seating
Although a large, flagship SUV, the new LX provides a car-like driving position with a more vertically positioned steering wheel, angled so that the driver feels in control, rather than having the sense of sitting above the wheel, as often experienced in other models in this segment.
The front seats are completely new, designed for optimal holding performance and comfort on every kind of drive. A broad shoulder area flows into a lumbar section designed to give the driver freedom of arm movement. Tall side bolsters reduce lateral movement, while the cushion is long and supportive to keep the driver’s posture secure when changing lanes or making turns.
The driver’s seat has 10-way power control, plus lumbar and up/down and forward/back headrest adjustment; the front passenger seat has eight-way adjustment and the same headrest position functions. There are memory settings for up to three drivers and the seats feature integrated heating with three levels and suction-type ventilation with an extra-high mode.
Front passenger area
The shape of the front passenger space reinforces the perception of horizontal width created by the instrument panel. When travelling on rough roads, the angle and thickness of the assist grip on the door panel and the soft padding on the door trim shoulder help passengers to sit securely and comfortably when travelling over uneven ground.
True to the Lexus principle of Omotenashi hospitality, there is easy access from the passenger seat to features on the centre console, including the wireless charging tray, seat heating and ventilation controls, the climate control system and useful storage spaces. The centre console box has an optional cooling function and has a lateral opening mechanism that can be reached from the driver and passenger side.
Second row accommodation
The second-row seats have soft lines to match those in the front. They can be reclined, with a lever positioned close to the occupant’s hip point for easy operation. The outer arm rests extend across the full width of the door and have soft padding.
Integrated seat heaters and ventilation are provided and sunshades and a black ceramic treatment for the edges of the window glass protect occupants from direct sunlight.
The wide rear console has left and right air conditioning controls and two USB-C ports, plus a 12V DC power outlet. There is also an additional button to open the centre console box from the rear.
A revised construction design for the front seats has helped produce more rear seat leg room, even though the LX’s wheelbase is unchanged. Access to the seats has been made easier by changing the shape of the interior pillar garnish and seat cushion.
Third row accommodation
The third row of seats in the seven-seat LX can accommodate two adults in comfort. Access is easier, thanks to Lexus’ first walk-in function: pressing the walk-in switch on the shoulder of the second-row seat automatically moves the front seat forward, followed by a forward tumble movement of the second-row seat. When the second-row seat is returned to its position, the front seat is also automatically repositioned.
The seats can be reclined through 10˚ and USB-C ports and drink holders are provided on each side of the cabin. A small storage compartment is also provided on the right-hand side.
Lexus has introduced a new automatic system for folding the rear seats to create a larger load space at the touch of a button, located in the rear of the boot. First, the front seats move forward, then the second row tumbles forward before the third row folds to complete a large, flat load area.
With five seats in place, there is room to stow five 77 cm large suitcases; in the seven-seat version there is still space to carry two 58 cm cabin suitcases , with all seats in use. Additional underfloor storage for small items is provided beneath the deck board in the five-seat and VIP models; in the seven-seat version this area contains a tool kit and warning triangle.
The load space also has a 220V AC power outlet.
FIRST-EVER VIP GRADE
The all-new LX is the first to be offered in a VIP version, offering even higher levels of comfort and luxury with two larger rear seats in a four-seat cabin layout with extra legroom, dedicated climate control features, a multi-function rear console and extended legroom with an ottoman to support the feet and calves.
Chief Engineer Takami Yokoo explained the thinking behind the VIP grade: “The aim is to provide the ultimate soothing space to relax, even on rough roads, so that business executives who travel long distances between cities can arrive refreshed and alert, ready to start work immediately. I am confident that, from the moment they set foot inside, customers will be able to feel the Lexus Omotenashi that is built into every aspect.”
The rear seats, exclusive to VIP grade, are designed to provide excellent support from head to toe. Upholstered in leather, they feature exclusive quilting on the side bolsters and urethane padding to filter out road vibrations and disperse pressure. The experience is enhanced with large, pillow-like head rests and integrated heating and ventilation.
The seats are electrically adjustable; the right-hand seat can be reclined by up to 48˚. Seat positions can be recalled using a memory setting.
The climate control system gains additional features, with ceiling vents providing an “air shower,” directing fresh air to the face and, in sunny weather, towards window glass heated by the sun. In cold weather, a warm “air curtain” extends out from the sides of the rear centre console, around the occupants’ ankles and shoulders, to prevent cooler air draughts from entering from the load area.
Passengers can ease away stress with a relaxation function, providing a choice of seven in-seat massage programmes, with settings to focus on the upper or lower body, shoulders or lumbar region. The system replicates massage techniques using a series of inflatable air chambers built into the seatback and cushion.
Additional features are provided in the rear seat behind the front passenger, with power adjustment of the upper seatback and an ottoman support which deploys from the back of the front seat. Together, the seat and ottoman are engineered to replicate the neutral body posture advocated by the space agency NASA – the posture that humans naturally assume in a gravity-free environment, considered to be the most relaxing. The toe area of the ottoman is concave, so the occupant’s feet are supported against side-to-side movement; the surface is stain-resistant synthetic leather, so shoes don’t have to be removed.
The front passenger seat can be folded and moved to its furthest forward position to give the rear passenger up to 1,100 mm of legroom. The rear seat entertainment screen (provided as standard) and front head rest can also be folded to gain a wider forward view.
The rear console contains a touchscreen for operating the climate control and a notepad table with palm rests. A wireless charger, USB-C and HDMI ports and a DC power outlet are also provided, together with a storage box.
The central feature in the rear console is an independent multi-information panel with an 11.6-inch touch screen. Its functionality allows the user to mirror the screen of their personal device, such as tablet or notebook, using an HDMI connection. Palm rests are designed into the console to make operation comfortable.
The screen also enables adjustment of the climate control functions for the rear cabin. USB-C ports and a DC power outlet are also provided, together with a storage box.
Upholsteries and ornamentation
The interior colour themes for the upholstery are Black, and new Hazel, Crimson and White/Dark Sepia. The VIP model can be specified in Black or Sunflare Brown.
The wood trims include a new Takanoha hand-finished art wood with a hawk feather motif. This is created by craftsmen by making a veneer of three layers of wood which is then shaved three times at different angles. Ash Open Pore Sumi Black is also new, featuring a strong woodgrain ash burl overlaid with Sumi Black; Walnut Open Pore and Shinanoku Black are also available.
- Innovative dual-display format with separate 12.3 and seven-inch touch screens in the centre console, each with specific functions
- New Lexus Link multimedia system with faster response and increased functionality,
- Additional security with new fingerprint authentication for starter push-button operation
- Premium audio systems include bespoke 25-speaker Mark Levinson Reference 3D Surround System
Dual centre displays
The new LX is the first Lexus to adopt an innovative dual screen arrangement in the front console with a combined display area of 12.3-inches and seven-inches display The screens are designed to complement each other, with specific functions.
The upper unit is a 12.3-inch high-resolution touchscreen dedicated to the audio, navigation and infotainment. It also presents images from the Panoramic View Monitor and, in off-road driving, the Multi-Terrain Monitor.
The lower, seven-inch display presents climate control and driving-related information. Toggle switches are provided beneath the display so that the temperature can be adjusted without having to look at the screen when driving on rough roads.
Lexus Link multimedia system
The LX is fitted with a completely new, powerful and smart multimedia package that operates faster and is more responsive than the previous system.
The 12.3-inch central touchscreen is designed to be as simple and intuitive to use as a tablet or smartphone, responding to pinch in/out commands to zoom and tap commands to select functions. Physical switches are retained for on/off and volume adjustment.
The screen is divided into display areas according to the level of information, while operation flow logic works to a three-layer structure of MENU – LIST – INFO, making easy to return to the home screen whenever desired.
Wireless smartphone integration is available using Apple CarPlay; Android Auto can also be used, with a wired connection. This gives users access to their favourite apps, such as for navigation and entertainment. A USB-A port is provided for quality playback of high-resolution audio sources; the port is illuminated for easy location at night.
The preferred profiles for up to three users can be stored in the system’s My Settings function, including audio, navigation, driving position, illumination and other settings.
The combination meter in the driver’s instrument binnacle is designed to present vehicle status data at-a-glance, in even in harsh driving conditions. The eight-inch TFT display presents graphics in High Definition for optimal visibility in all light levels. It is complemented by four analogue gauges, including a battery voltmeter and engine oil pressure gauge.
The 10-inch head-up colour display operates with high brightness for clarity, even in strong daylight or when driving on reflective snowy roads Key vehicle information is projected in the driver’s line of sight, helping to minimise head and eye movement and helping the driver concentrated on the road ahead.
The position and brightness of the display can be adjusted using the multi-information display. Each driver can store their preferred setting with a memory function, linked to their seat position memory setting.
Fingerprint authentication, a Lexus first, is provided on all grades, using a fingerprint sensor to authorise operation of the push-button starter. The innovation provides another layer of protection against vehicle theft.
When the driver has the smart key on their person and touches the sensor while depressing the brake pedal, their fingerprint is checked against pre-registered information. The engine will not start unless there is a match with a registered user.
Up to 10 fingerprints can be stored so multiple users can be accommodated, or the main user can store prints from different fingers (so operation isn’t compromised if one finger is injured).
The system can be linked to the vehicle’s memory function, so the driver’s preferred settings can be restored as soon as they start the engine. A fail-safe system is available should the authentication system fail to operate.
Climate control with nanoe™ X technology
The climate control system uses a compact and lightweight X-turn evaporator that gives higher performance compared a conventional evaporator unit while contributing the LX’s overall fuel efficiency.
The climate control settings are presented on the seven-inch centre display, with visual guides to adjusting performance for four-seat individual control. The Lexus Climate Concierge function co-operatively controls the air conditioning, seat heating and ventilation and steering wheel heater to provide each occupant with a comfortable environment, with performance adjusted to suit all weather conditions. If a front or rear seat is unoccupied, the seat heating and ventilation are automatically turned off to help save fuel without compromising the comfort of other passengers.
The climate control uses nanoe™ X, a Panasonic air conditioning technology, which discharges mildly acidic ions through the centre air vent. These ions help inhibit viruses, bacteria, allergens and odours, contributing to fresh and clean cabin air. Nanoe™ X is also beneficial to passengers’ hair and skin.
Compared to the original nanoe™ technology used previously in Lexus vehicles, nanoe™ X is 10 times more powerful; laboratory testing has shown that 99% of viruses and bacteria can be inhibited in one hour of operation.
Digital rear-view mirror
The digital rear-view mirror provides a wide, clear view, using a rear-mounted camera. This avoids any obstruction in the driver’s view that might be caused by other passengers or luggage.
The digital image can be adjusted for clarity to gain excellent visibility that is unaffected by night-time conditions or poor weather. Mode settings are also provided to decrease glare, increase brightness and to set the display area and angle. The mirror can easily be switched to standard, optical mode if preferred.
Ambient interior lighting
The LX’s cabin features an ambient lighting system that lets the driver reflect their mood, the journey or the time of day. The illumination is soft and welcoming with a wide palette of 64 different colours to choose from, highlighting the footwells, door panels and centre console.
The colour selection includes 14 pre-selected themes, specially designed to reflect different moods inspired by nature. Themes and colours are selected using the centre 12.3-inch display, with adjustment for tone and brightness.
Premium Sound systems
The new LX is available with a bespoke Mark Levinson Reference 3D Surround System that uses no fewer than 25 speakers – the largest number yet in a Lexus vehicle. These are arranged to create a distortion-free sound stage throughout the interior.
To perfect the three-dimensional sound experience, dedicated acoustic tuning was carried out for each cabin style – five and seven-seat and the four-seat VIP configuration, with and without a sunroof.
The system uses Quantum Logic Immersion (QLI) for more precise tuning quality than has previously been possible. Clari-Fi technology is applied to recreate audio quality that is lost when sound is captured in lower-quality compressed files. Mark Levinson Pure Play uses nine 10 cm integrated tweeter/mid-range Unity speakers, placed at the same height around the cabin. There is also a powerful 22.4 cm subwoofer and, adding a vertical dimension to the sound experience, four 4 cm ceiling-mounted speakers.
A 10-speaker system is also available, providing an outstanding acoustic space with clear mid-to-high range sounds and a powerful, deep bass that create a realistic live performance atmosphere.
A large-capacity subwoofer uses the base reflex structure of the rear speakers and the body framework to achieve rich and crisp low-frequency sound reproduction.
The amplifier allows playback of high-resolution sound sources that contain more information than a compact disc, delivering a sound experience like the atmosphere in a live venue.
POWERTRAINS AND PERFORMANCE
- Two new V6 twin-turbocharged engines 3.5-litre petrol and 3.3-litre diesel
- Higher power and torque output compared to previous, larger capacity V8 units, but with improved fuel economy
- New 10-speed Direct Shift automatic transmission
The all-new LX introduces two new chapter Lexus engines, twin-turbocharged petrol and diesel V6 units which, although smaller in capacity than the model’s previous naturally aspirated V8 units, deliver significantly more power, higher torque and improved efficiency. They also provide powerful, linear acceleration thanks to their extended torque characteristics, up to high engine speed. Both are matched to a new 10-speed Direct Shift automatic transmission.
3.5-litre twin-turbo V6 petrol
The Lexus LX 600 is powered by a new 3.5-litre V6 petrol engine with a twin turbocharger. In terms of power and torque, it marks an increase on the performance of the previous 5.7-litre V8 engine, developing 409 DIN hp/ 305 kW at 5200 rpm and peak torque of 650 Nm from 2000 to 3600 rpm. The twin turbo system helps secure a flat torque curve, giving extra boost at low engine speeds and easily controllable power when travelling off-road.
The engine’s design is tailored for use in an SUV, ensuring consistent performance when travelling on steep slopes or rough roads. For example, the oil pan has been designed so that proper oil pressure and flow are maintained even on slopes of 45 degrees – up/down and left/right.
The engine’s design adopts technologies developed in motorsport to achieve strong fuel economy and emissions, supported by high-speed combustion technology and world-class thermal efficiency. Features include straight intake ports, a long stroke and laser-clad valve seats. The piston design has a new lip feature which, with precise multi-hole fuel injectors, ensures a rich fuel-air mixture for stable combustion during cold start-ups. The fuel injection is Lexus’ D-4ST system which provides low-pressure port and high-pressure direct injection. Dual VVT-i gives optimised valve control on both the intake and exhaust sides.
The cylinder block has a highly rigid construction with a ladder frame and features a cast iron crank cap. The valvetrain has an increased included valve angle, helping reduce the engine’s overall height, while weight has been saved in details such as the new aluminium intake manifold and high-strength connecting rods.
The twin-turbo unit gives accurate boost control using an electrically activated wastegate valve. Featuring an optimised blade shape, it boosts power while maintaining fuel economy, emissions compliance and quiet operation.
Both the petrol and diesel engines are equipped with a new electronically controlled coupling fan which helps achieve quicker engine warm-up and reduce friction losses, contributing to overall fuel economy and quieter performance and also reinforcing the engine’s durability in rough road conditions. It can operate at different speeds, rather than simply on or off, in line with the driving conditions.
3.3-litre twin-turbo V6 diesel
The diesel V6 engine in the new LX 500d uses a two-way turbocharger and low-flow combustion technology to achieve higher output and performance than the previous V8 unit, with a maximum 295 DIN hp and 700 Nm of torque.
Lexus’ first two-way twin turbo system switches automatically to single turbo operation at low speeds and twin-turbo running at high engine speeds, giving powerful acceleration response and high torque at low engine rpm.
The engine benefits from a series of new features, including new-design air intake ports (helical and tangential) to promote efficient air flow; steel pistons that provide both strength and light weight; and high-diffusion fuel injectors. The high-precision solenoid injector can operate at pressures up to 270 MPa – a first for Lexus. Other weight-saving details include integration of the cylinder heads and exhaust manifold; a thin cast iron construction for the cylinder block; and a hollow-cast camshaft.
The air intake has a new cleaner element that gives better dust collection when travelling over rough terrain. Its construction reduces engine booming noise with sound-absorbing material added to the cleaner case.
10-speed Direct Shift automatic transmission
Both engines use a new 10-speed Direct Shift automatic transmission, in place of the eight-speed gearbox in the previous LX. It is designed with close gears for rhythmical shifting, while the wide ratio range supports both power and fuel efficiency.
When developing the mew transmission, Lexus engineers paid particular attention to adjusting the ratios to match the interval between second and third gear. This has produced closer ratios and equal intervals between gears, so that shifts are made at the same engine rpm.
A low, wider ratio for first gear provides smooth and powerful acceleration at start-off and robust off-road performance. Conversely, the high ratio for 10th gear allows for quiet and efficient high-speed cruising.
The transmission features a new torque converter with a multi-plate lock-up clutch, with a wider lock-up range and higher response. Although the unit features more ratios, its size and weight are near-equivalent to the previous eight-speed. For off-road strength, a guard has been fitted to the transmission’s oil pan.
Active Noise Control is used to counter out unpleasant booming engine noise. Noise-cancelling sound waves are calculated in line with the engine speed and noise picked up by a microphone in the cabin. These are then output through the vehicle’s audio speakers.
The V6 petrol engine’s note can be amplified with Engine Sound Enhancement, giving a stronger dynamic feel when accelerating or decelerating. It operates when the LX is in Sport S, Sport S+ and Custom drive modes.
Lexus Driving Signature gives the driver a constant, rewarding sense of control and connection with the vehicle
- First use of Lexus’ Global Architecture GA-F platform, designed specifically for a body-on-frame vehicle
- Highly rigid, lightweight body featuring aluminium panels and high-tensile strength steels
- New suspension systems, with Active Height Control and Adaptive Variable Suspension
- New Electric Power Steering and Electronically Controlled Braking systems
Lexus’ focus for the new LX’s performance was to achieve a relationship between car and driver that provides faithful, linear response with easier steering, use of the pedals and shift control and overall driveability that is unaffected by the vehicle’s height and weight. The target was safe, stress-free off-road driving and perfect cruising comfort that avoids fatigue on long journeys.
Lexus has retained a body-on-frame construction and tailored the LX’s dimensions to ensure it remains a thoroughbred SUV, equipped to deal with challenging rough road conditions and provide superb on-road comfort and stability.
These fundamental qualities are boosted by the introduction of the new Lexus Global Architecture GA-F platform, designed specifically for a body-on-frame vehicle.
Lexus Driving Signature
The quality of the LX’s performance and handling fully expresses the Lexus Driving Signature, inspiring confidence in the driver through a constant sense of control and connection with the vehicle and faithful, linear response to their use of the accelerator, brakes and steering.
To strike the ideal balance between ride quality and handling, Lexus engineers increased the vehicle’s body rigidity and tuned the suspension. The resulting combination of linearity and balanced performance makes the driver feel as one with their vehicle with an immediate feeling of confidence.
Global Architecture GA-F platform
The new LX is the first Lexus model to use the new GA-F Global Architecture platform, designed for body-on-frame vehicles.
The robust, high-strength frame is designed to deal with the particular stresses and forces encountered in challenging off-road driving, with 20% greater torsional rigidity overall. The cross-section of the side rails has been optimised and the positioning of the cross-members has been carefully judged to achieve the best results. Ultra-high tensile steel is used to reinforce key areas and the front cross-member has a new bridge structure. Further benefit is gained from an increase in the rigidity of the steering gearbox and from a towing receiver that is built into the frame itself.
In a world first, curved tailor-welded blanks are used in the frame. These are laser-welded in the side rails and cross-members and then press-formed to join sheet steels of different thicknesses and type, saving significant weight while achieving high rigidity.
Highly rigid, lightweight body
The focus for the LX’s body construction was to achieve high rigidity to support stable handling both on and off-road, but with weight-saving measures to secure a lower centre of gravity. CAE (computer-aided engineering) was used to evaluate the cabin’s torsional rigidity and identify its deformation behaviour in relation to the steering. This allowed the development team to understand which parts had the greatest impact when driving; these were then incorporated into the cabin design to gain excellent rigidity. Extensive spot-welding along the cowl and use of structural adhesive on the floor and door openings further contributed to the rigid construction.
The resulting excellent cabin rigidity, enhances on and off-road performance, steering responsiveness and feedback, rear grip feel, ride comfort and driving feel.
The LX’s kerb weight has been reduced by about 200 kg compared to the previous model, with lightweight materials used in its construction further contributing to the vehicle’s lower centre of gravity. The reduction in the car’s inertial mass means there is less delay in response when the driver presses the accelerator or turns the wheel. This and the avoidance of a “top-heavy” feel inspire confidence in the driver when travelling on rough roads.
This is the first Lexus model to feature an aluminium roof, strengthened by a beading design on the upper surface. Aluminium is also used for the bonnet, side doors, back door and wing panels, while the main frame components are made of hot-stamped and high-tensile steels.
Aerodynamic features are incorporated in the LX’s design to manage the air flow over the vehicle and minimise turbulence, helping maintain a flat, comfortable ride, stable handling and fuel efficiency.
Details include enlarged front spats to reduce wind hitting the tyres. Aero fins on the door frame behind the mirrors and the side of the rear combination lamps channel air efficiently along and away from the car. Further fins in the front wing liners and rear bumper seal regulate the air flow inside the wheelhouses, reducing turbulence.
With the goal of stable handling and comfort in all driving conditions, Lexus has produced new suspension designs for the LX.
At the front there is a high-mounted double wishbone set-up, with geometry optimised to ensure stable posture in cornering and under braking, suppressing front lift. The large upper arm and lower arm cross-section have been designed to accommodate the larger 22-inch wheels, with ample stroke to ensure excellent rough road capability.
The coil springs are made of 1300 MPa steel, making them lighter yet reliable for stability and comfort performance on all surfaces.
The rear suspension is a new four-link rigid axle, tuned to reduce shock and vibration. With the new GA-F frame, it was possible to introduce bends at the rear axle to achieve a better position for the shock absorbers. These have been moved outwards from the suspension’s lower control arms, so their angle is aligned with the suspension movement. As a result, the movement of the unit matches the movement of the tyre to give excellent ride comfort and roll settling.
The lower control arm has a higher attachment and is positioned parallel to suppress axle steer, for better stability under braking and when experiencing shock from external forces.
The suspension stroke has been increased by 20 mm compared to the previous model, giving impressive ground-covering performance in off-road driving.
Active Height Control and Adaptive Variable Suspension
The LX’s new four-wheel Active Height Control (AHC) and Adaptive Variable Suspension (AVS) adjust the hydraulic pressure in the shock absorbers to adjust vehicle height and damping force in line with the driver operations and the road conditions, contributing to vehicle controllability and ride comfort.
In AHC operation, oil is pumped to the shock absorbers which then extend or compress to adjust the vehicle height and spring strength. Rear spring switching valves enhance ride comfort in straight line driving, reducing the roll in cornering by as much as 25% compared to the previous model, and minimising pitch under acceleration and deceleration.
The system has three settings: Normal, H1 and H2; there is also a Low setting for when the vehicle comes to a stop to make exit and entry easier. Height adjustments take less than half the time compared to the previous LX, thanks to a new hydraulic circuit and controls; for example, moving from Low to Normal takes around six seconds and Normal to Low in about two seconds. Notably, the Normal height setting is 23 mm lower than before, contributing to on-road handling stability.
The system works in co-operative control with the vehicle’s transfer system in L4 or H4 ranges and with Multi-Terrain Select. When these are engaged, it will automatically adjust to H1 or H2, so the driver can enjoy rough road driving without having to select the vehicle height. When the ignition is turned off, AHC automatically moves to the Low position.
The AVS has also been significantly upgraded to provide precise and seamless control in all driving situations, helping the LX deliver the handling and ride quality that are fundamental to the Lexus Driving Signature.
The new, lightweight system has 650 damping force levels, giving instantaneous, seamless adjustment and control in response to the road surface conditions. Together with the vehicle’s Drive Mode Select, AVS adjusts the level of damping force according to the mode chosen by the driver and the driving conditions. It has three control modes – Normal, Sport and Comfort; when driving in L4 range, the damping force is adjusted to increase vibration damping performance and reduce body rocking.
The AVS’ Vehicle Speed-Sensing Control reduces damping force at low speeds and increases the level at higher speeds, while Roll Posture Control gathers input from steering, yaw rate and linear G-sensors to control damping force on all four wheels to maintain vehicle posture and occupant comfort when cornering. Anti-Pitch Control helps maintain a flat, stable ride by controlling damping force under acceleration and deceleration, and Roughness Sensing Control maintains low damping force when vibration is detected, making for a more comfortable ride over uneven surfaces. The Repercussion Control reacts to vehicle body movement and shock absorber movement to smooth out the effect of even small repercussion, while Unsprung Damping Control increases damping force to suppress any resonance or rattling detected in the car’s unsprung parts.
The new LX uses a full-time all-wheel drive system engineered for robust off-road performance and on-road stability.
In addition to the standard rear and centre differential locks, there is an additional front differential lock – a first for a Lexus model. A unique feature in the LX’s segment, these three electronic differential locks give the vehicle outstanding ability to deal with challenging off-road conditions.
If a wheel begins to slip or loses contact with the ground, the driver can engage the corresponding differential lock so the opposite wheel in contact with the ground can rotate and propel the vehicle forwards.
The transfer case has been revised to handle a higher drive force and deliver better efficiency; its ground clearance has also been increased by 18 mm. Strength, weight-saving and efficiency improvements have also been made to the front and rear differentials.
The status of the car’s AWD system, the differential locks and the transfer range are shown on the seven-inch display in the centre console.
Electric Power Steering
A rack-assisted electric power steering system is used on the LX for the first time, giving more freedom for fine tuning to give clear on-road reel and confident control when driving off-road, supporting the Lexus Driving Signature. Its telescopic column has a wider diameter intermediate shaft and tube, which increases the unit’s rigidity and helps filter out the small vibrations that can be transmitted to the steering wheel when the engine is idling.
Chief Engineer Takami Yokoo considers the new steering to be “an incredible improvement,” allowing for a greater range of adjustment, faithful response to driver inputs and lighter on-road performance for easier manoeuvring. Drivers can easily find a comfortable position for the steering wheel with a 50 mm vertical range and 60 mm telescopic range of power adjustment.
Electronically Controlled Brake system
The electronically controlled brake (ECB)system uses a sensor in the brake pedal to calculate the required degree of braking force to match the driver’s intention, giving confidence-inspiring linear control and a natural feel on all road surfaces.
Slotted-fin ventilated discs are used front and rear, those at the front with four-piston callipers, offset for stable performance and even pad wear.
The ECB adds an extra sense of security when using Multi-Terrain Select in off-road driving, providing precise braking control to counter any wheel slip or spin.
An electronic parking brake is fitted as standard.
SAFETY AND DRIVER ASSISTANCE TECHNOLOGIES
- Lexus Safety System + as standard with improved and additional functions
- Active safety features for safer low-speed manoeuvring
- Multi-Terrain Select and Multi-Terrain Monitor for precise vehicle control and positioning on challenging terrain
- Crawl Control and new Turn Assist, plus world-first Back Underfloor View
The Lexus Safety System + is provided as standard on the new LX, benefiting from improved functions and new features to help protect against many common accident risks and help the driver maintain safe driving performance. Additional active safety technologies help with safer manoeuvring, while the passive protection provisions include a robust vehicle structure and a full complement of cabin airbags.
The driver assistance systems provide valuable support in controlling and placing the vehicle when driving in challenging off-road conditions, and when making low-speed manoeuvres in on-road driving, such as parking and negotiating narrow passing places.
LEXUS SAFETY SYSTEM +
Upgrades to the Lexus Safety System + cameras and millimetre-wave radar have expanded their operating range and enabled new driver assistance functions to be introduced.
The Pre-Collision System (PCS) is now able to recognise oncoming and preceding vehicles and pedestrians* in the car’s path in both day and night-time driving; bicyclists* can be picked out in daylight driving. The system also gains Intersection Turning Assistance*, which can detect a high collision risk with oncoming vehicles, or crossing pedestrians. It will provide a warning and apply automatic braking if the driver turns left or right in the path of an oncoming vehicle in an opposite lane, or a pedestrian approaching from the opposite direction.
The PCS also gains new Emergency Steering Assist*. Operating in daytime driving, this provides extra steering support when the driver makes an emergency manoeuvre to avoid a hazard, maintaining vehicle stability while keeping the car within its traffic lane during the day.
DYNAMIC RADAR CRUISE CONTROL
The Dynamic Radar Cruise Control (DRCC) uses the millimetre-wave radar and monocular front camera to maintain a safe distance from the vehicle ahead, automatically controlling acceleration and braking, slowing the car to standstill if necessary. The system has a new Curve Speed Reduction feature which automatically slows the vehicle if it judges its speed is too high for a bend in the road ahead. This helps reduce the burden on the driver, particularly when travelling on long, winding roads. Indicator-linked pre-acceleration is also new, automatically accelerating the LX to its target speed to reduce the distance to the vehicle ahead when the indicators are used in preparation for a lane-change overtaking manoeuvre, at speeds of 80 km/h and above.
ROAD SIGN ASSIST
The Road Sign Assist (RSA) system* uses the front camera to detect a wide range of command road signs, displaying them on the vehicle’s multi-information and head-up displays. If the driver begins to make an overtaking manoeuvre when the system has recognised a “no overtaking” sign, it will warn the driver by flashing the sign in the display. RSA also now co-operates with the DRCC to alert the driver to adjust the car’s cruising speed in line with a change in the road’s speed limit.
LANE TRACING ASSIST
The Lane Trace Assist provides extra support when driving through a bend by increasing the lateral G-force limit. Using artificial intelligence technology (AI), it can now operate in a wider range of driving scenarios to keep the car centred in its traffic lane. It can provide continuous support even when lane markings are not visible, by following the path of the vehicle ahead and recognising the road margins. Lane Departure Alert warns the driver and, if necessary, applies steering force, if the vehicle deviates from its lane without the indicator being operated.
The new LX adopts Lexus’ BladeScan™ Automatic High-beam System (AHS) This uses rapid-spinning mirrors to direct light from the headlight LEDs through a lens to illuminate the road ahead. The precise control of light distribution widens the range of high beam illumination and provides superior performance when the lighting is automatically adjusted to avoid dazzling other drivers.
*Not available in Georgia or Azerbaijan.
Additional active safety features
The LX is available with numerous additional active safety features that make manoeuvring the vehicle easier and safer.
It is the first Lexus to offer a new Standstill Blind Spot Monitor. This uses a radar to detect vehicles and bicycles approaching from rear when a door is being opened, alerting the driver with a buzzer and a light indicator in the appropriate door mirror. This function is in addition to the regular Blind Spot Monitor, which detects vehicles travelling in the driver’s blind spot in adjacent traffic lanes, and Rear Cross Traffic Alert with auto-braking function.
Extra parking support is provided with a Parking Support Brake which detects both objects and people in the car’s path, automatically controlling drive force and braking control to help prevent or mitigate damage. In conjunction with the Blind Spot Monitor, it can also detect other vehicles during parking.
Comprehensive passive safety
The LX provides fundamental impact protection with an impact-absorbing structure that uses high tensile strength steel in key areas to maintain cabin integrity in the event of a collision. The impact beams in the doors have an aluminium and steel hybrid construction to prevent deformation, keeping the door from bending inwards.
Ten SRS airbags are provided in the cabin, including driver, front passenger, driver’s knee, front centre, front side and curtain shield airbags. In the VIP model, the rear seats are fitted with additional cushion airbags.
The driver is kept fully aware of the vehicle’s immediate surroundings with the Multi-Terrain Monitor. This uses four high-resolution digital cameras around the car to create a composite image, presented on the 12.3-inch multimedia displays. With this level of detail, the driver can more safely judge their manoeuvres, whether negotiating off-road terrain, or checking for obstacles when parking. The rear camera has a washer so that images are kept clear even in bad weather or when driving over muddy ground.
The monitor’s scope has been increased with Lexus’ first Front Underfloor View. This is particularly useful on uneven or rocky ground, allowing the driver to check the area immediately around the front tyres. This is provided in conjunction with the world’s first Back Underfloor View, which effectively lets the driver see through the vehicle floor to view the area around the rear wheels when reversing. These are both a composite of images recorded by the cameras, rather than being shown in real time (a “not live” alert is presented on the display). The system can also be used in low-speed on-road driving to help negotiate narrow spaces and passing places, using settings including a Panoramic View, Side Clearance View and Cornering View.
Crawl Control and Turn Assist
Taking more of the burden off the driver when negotiating very rough or slippery conditions, Crawl Control can be activated at the press of a button, when travelling at speeds below 10 km/h. The system automatically controls engine output and braking, so the driver can focus on accurately steering the vehicle.
The system has five speed modes to gain the best stability in a wide range of conditions: Lo (rocks, downhill mogul and rubble); MIDL and MID (uphill mogul); MIDH (snow, mud, uphill rubble and sand); and HIGH (gravel, dirt, uphill mogul and grass).
When negotiating tight turns off-road, additional support is available from the Turn Assist function, activated by a touch-switch in the multimedia display. This uses brake pressure to increase the response to the driver’s steering inputs, so less turning of the wheel is needed to position the vehicle. Using a steering angle sensor, the system will automatically determine the driver’s turning intention and increase brake pressure on the rear wheel on the inside the turn; when the wheel locks, the pressure is held, then reduced, giving the vehicle a tighter turning radius.
The LX’s Multi-Terrain Select (MTS) system has a new Auto mode, enabling it to predict the optimum operating mode, adjusting drive force and braking control based on information from vehicle status sensors and the driver’s throttle and brake inputs.
The system can now be used in both L4 and H4 ranges, with Auto/Sand/Mud/Rock for L4 and Auto/Dirt/Sand/Mud/Deep snow for H4. After switching MTS on, the driver uses the mode select dial on the centre console to choose their mode, then confirm their choice on the multimedia touchscreen.
Drive Mode Select
The same selector dial is used to activate the driver’s preferred drive mode, which integrates control of the powertrain, steering, air conditioning and suspension to optimise vehicle performance accordingly. Four modes are provided: Eco, Comfort, Sport S and Sport S+, together with a Custom mode in which the driver can make their own combination of function settings.
The LX is also equipped with Downhill Assist Control, Trailer Sway Control and Hill-Start Assist Control, providing further automatic assistance to help the driver control the vehicle.
