Lexus has a proud history of pushing boundaries and challenging the status quo. Since its founding in 1989, it has repeatedly pioneered new thinking and new products that have changed people's perceptions and reshaped the luxury car market. It has constantly evolved the concept of what luxury means, not just by creating desirable and exciting products, but also by redefining the complete ownership experience.

Its record of achievement today welcomes a new name: the Lexus LBX.

The all-new, all-hybrid electric LBX is the smallest Lexus yet, but fully deserving of its status as a landmark model, one which breaks down the traditional luxury hierarchy and which will be a game-changer for the brand in Europe.

LBX stands for Lexus Breakthrough Crossover, a compact SUV that will extend Lexus' brand appeal into new market territory. It embraces contemporary ideas in design and technology while maintaining the distinguishing Lexus qualities of the luxury craftsmanship and Omotenashi hospitality.

This is a car that's simple, casual and easy to live with, but which makes no compromises in quality and attention to detail: the essence of Lexus has been distilled into a smaller package, transcending customers' traditional expectations of what a premium compact SUV can offer.

It also breaks new ground by disrupting the traditional grade strategy to give owners more freedom to express their individual taste and sense of style. True to Lexus' commitment to "making luxury personal," the LBX will be offered in a choice of four "atmospheres" in addition to its base grade. Rather than being defined by the level of equipment or comfort features, these atmospheres focus on expressing different refined, dynamic or sporty themes through styling details, colours, textures and finishes. A new Lexus Bespoke Build programme will offer yet more personalised options.

The LBX is also a breakthrough for Lexus as a business in Europe. For the first time, Europe has been the lead global region for the development of a new Lexus vehicle. This influence will help the LBX become one of the best-sellers for the brand in Europe.

The use of a three-letter name is significant - previously only the LFA supercar has enjoyed that distinction. The choice of the name LBX demonstrates Lexus' commitment to and trust in its new model. Just as the LFA showed a different side to the brand in terms of attitude and performance, so the LBX will in its own way expand its reach and profile.

As a new entry point to Lexus' well-established SUV line-up, it offers strong appeal to a younger audience and those who may not have considered a Lexus before. It will be an attractive proposition to those seeking to downsize or purchase a second vehicle, meeting their new lifestyle requirements.

Chief Engineer Kunihiko Endoh comments: "Our aim was to challenge the conventional concept of a luxury car. We have thoroughly pursued a driving experience that enables a natural dialogue between the driver and their vehicle and a design that has an refined presence."

The Lexus LBX's styling establishes a new Lexus identity with a "Resolute Look" front design that reinterprets the famous spindle grille. While the exterior dimensions are more compact than any other Lexus, the look is muscular and powerful. Inside, the emphasis is on driver-engagement with a focused driver's cockpit based on Lexus' Tazuna concept, and on creating a light, open feel with excellent visibility and an instrument panel that wraps around smoothly into the door panels.

In doing things differently with the LBX, Lexus has taken a new approach to building a model range, introducing choices that better reflect how today's customers seek cars that match their personal style and character.

Following its world debut, the LBX will go into production in late 2023. Sales will begin in European and selected global markets from early 2024.

EXTERIOR DESIGN: A NEW LEXUS IDENTITY

Lexus' design ambition was to create a car that is more relaxed than formal in character, displaying an authentic, effortless style that people will instantly feel a connection with.

The most significant aspect of the design is a new frontal arrangement that "breaks" the spindle grille - a design hallmark for the past decade - leading Lexus into a new era.

Koichi Suga, General Manager Lexus Design, explains: "We have 'deconstructed' the spindle grille to make way for a new design. We've succeeded in creating a new front face identity that's completely different from before yet is instantly recognisable as a Lexus."

The grille has been unified in a single trapezoid shape, positioned below a narrow aperture that runs beneath the leading edge of the bonnet, linking the slim headlight units. The design draws on the heritage of Lexus' "Resolute Look." Introduced with the LF-S concept car of 2003, this became a signature styling cue for Lexus production models from the early 2000s.

The seamless, frameless grille generates the lines of the Lexus LBX's spindle body, contributing to the car's strong, dynamic stance. It is also aerodynamically efficient, helping smooth airflow over and around the car. The new headlight design creates a strong visual signature, with the daytime running lights and turn indicators integrated in bi-functional units. With this new arrangement, the lights' distinctive L-shape has been changed to face out rather than inwards, to match the direction of each indicator light.

Following the principles of Lexus Next Chapter Design, the car's identity and proportions are rooted in the driving experience it delivers. The front pillars have been pulled back, making the cabin appear compact and the bonnet longer for a sporty profile. The flared wings express power and accentuate the large (18-inch) wheels and tyres, while short overhangs and a bold tightening of the area around the rear doors evoke nimble, dynamic performance.

The rear of the car also projects a strong stance. The licence plate has been moved down to the bumper so that the LEXUS lettered signature on the back door is more prominent on the clean expanse of the back door. Similarly, the latest evolution of the Lexus signature L-shaped light bar has greater visual impact, with the turn signal and reversing lamps having a subdued presence when not illuminated.

The Lexus LBX is 4,190 mm long, 1,825 mm wide and 1,545 mm high and has a 2,580 mm wheelbase. The low-slung bonnet, belt mouldings flush with the body, a gate-style rear roof spoiler and precise light cluster designs enhance aerodynamic performance and contribute to the LBX's efficiency, stability and responsive performance.

The exterior colour choices include vivid shades and Lexus' deep-lustre sonic finishes. Emotion and Cool versions of the LBX can be specified with bi-tone paintwork, combining any colour option with a contrast black roof.

DYNAMIC PERFORMANCE: A NEW LEXUS PLATFORM

The LBX is the first Lexus model to be constructed on a variation of the GA-B small car global architecture platform. It has been fundamentally adjusted to meet Lexus requirements, giving it the core benefits of a low centre of gravity, wide tracks, short overhangs and a highly rigid body. It is also the foundation of the car's fun-to-drive character, helping secure the Lexus Driving Signature in the smallest package yet. This helps create a natural dialogue between driver and car that ensures confidence, control and comfort at all times.

Chief Engineer Endoh explains: "To realise the Lexus sense of being at one with the car, we worked to achieve nimble driving that maximises the benefits of the car's small size and light weight. At the same time, we focused more than ever on honing the fundamental characteristics without relying on electronic controls."

The body is strengthened with structural adhesives and short-pitch welding, and strategic placing of bracing and reinforcements. At the same time, vehicle weight has been kept down by the use of lightweight materials, including an aluminium bonnet and moulded resin wheel arches, rockers and lower door sections. Strong yet light hot-stamped materials are used in the centre pillars and bumper reinforcement.

Setting the hip-point as low as 285 mm helps make the driver feel more at one with their vehicle, while maintaining an excellent view from the wheel, particularly when driving in city traffic.

Front and rear suspension systems are designed for high rigidity and light weight, giving the Lexus LBX agile, stable cornering and steering response with smooth ride comfort. All versions feature a MacPherson strut design at the front; front-wheel drive models use a rear torsion beam while the all-wheel drive LBX has a double-wishbone arrangement.

The electronically controlled braking system includes Vehicle Braking Posture Control. This automatically balances front and rear brake force distribution to suppress pitching and maintain linear, reassuring performance. It also helps reduce vehicle roll when cornering, keeping the car comfortable and stable and filtering out vibrations.

POWERTRAIN: A NEW GENERATION OF LEXUS HYBRID DRIVE

The LBX is powered by a new generation, self-charging Lexus hybrid electric system featuring a compact and lightweight 1.5-litre three-cylinder engine. The principal hybrid system components have undergone a substantial redesign, including the transaxle and power control unit, to improve efficiency, reduce losses, save weight and reduce size. There is also a new low resistance, high output, bi-polar nickel-metal hydride (NiMH) battery which enables extra electric motor support when accelerating and extends the car's all-electric EV driving capability.

The technology developments have allowed Lexus to focus on more rewarding performance and a level of driving pleasure that was not possible with previous systems. Maximum output from the full hybrid system is 136 DIN hp/ 100 kW with peak torque of 185 Nm.

The engine operates with world-class thermal efficiency, supported by high-speed combustion technology and design features such as straight intake ports and laser-clad intake valve seats. Other key features include ultra-lightweight pistons engineered for operation at high rpm and electronic intelligent variable valve-timing.

The powertrain also features a newly designed transaxle. The revised power control unit is mounted directly above the transaxle, a design which helps give the LBX a low bonnet line. Further space is saved by the two motor-generators being located on separate shafts, reducing the drivetrain's overall length.

The NiMH battery is an all-new bi-polar unit with reduced weight and a more compact design, yet it delivers higher output with much quicker response. Thus, it contributes to the LBX's performance with instant, powerful acceleration like that of battery electric vehicle, as well as its fuel efficiency. It benefits from a redesigned cooling system to help prolong battery life and performance.

The powertrain is tuned for enjoyable performance, whether driving around town or on winding country roads, with faithful handling and a linear acceleration feel that is more closely aligned to the driver's use of the accelerator pedal. Drivability is also enhanced by Hybrid System Control that closely matches engine sound and acceleration. Thanks to the hybrid system upgrades, all-electric EV driving can be enjoyed at higher speeds and over longer distances, maximising the LBX's efficiency.

The LBX's authentic SUV quality includes the option of Lexus' E-Four all-wheel drive, which introduces an additional electric motor on the rear axle. When pulling away, cornering and driving on low-grip surfaces, the system automatically directs drive force to the rear wheels, helping keep the vehicle stable and maintaining driver confidence.

The LBX's luxury status is witnessed by the lengths Lexus has gone to manage noise and vibration (NVH). These include adding a balancer shaft to the engine to reduce vibration that can generate a booming effect in the cabin. Special attention has been paid to the doors where damping sheets have been introduced to suppress high frequency noise but enhance low frequency noise to give a distinct and pleasing sound. To counter vibration and road noise from the roof, high-damping mastic has been used together with an extensive silencer made of a highly effective insulating material. Other measures include a seal around the entire edge of the bonnet and noise insulating and absorbing sheets, liners, mouldings and foam in key areas throughout the car. Beneath the vehicle, high-damping and structural adhesives play their part in reducing noise and vibration, while also contributing the car's overall rigidity.

INTERIOR DESIGN: SIMPLICITY AND ELEGANCE, CRAFTSMANSHIP AND HIGH QUALITY

Lexus designers sought to create a simple and refined interior that creates the feel and atmosphere of a higher segment model. This effect is founded on three key elements: good visibility with an open view out and a simple, smooth instrument panel; the sense of wide interior space; and a centre console with a commanding presence.

The premium quality and attention to detail is witnessed in a choice of upholsteries and trims with strong visual and tactile appeal. As well as top-quality semi-aniline leather, the options include a vegan-friendly interior that uses synthetic leather and materials for the seat coverings and steering wheel, shift lever and door trims. The LBX also features new Tsuyusami charcoal trim inlays, created using a new film technique that uses multiple layers to give a highly textured appearance with a sense of depth. Ambient lighting adds to the Omotenashi effect of people being made welcome and feeling completely at home in the vehicle. Highlighting different parts of the cabin, the lighting design provides a range of 50 colour options, curated in themes that evoke different moods.

The driver's cockpit is an interpretation of Lexus' Tazuna concept, first introduced on the NX mid-size SUV. This positions principal controls and information sources immediately around the driver, so their operation only requires minimal movements of hand or eye. This helps keep the driver focused on the task of driving, with least distraction. The position and angle of the steering wheel were precisely calculated to give the driver a rewarding sense of control.

Here, the Tazuna concept is enhanced with a new, 12.3-inch fully digital instrument display, featured in a Lexus for the first time. The lay-out and prominence of the meters and data change according to the drive mode selected and can be customised to suit individual preferences. An optional head-up display is also available.

Thanks to the Lexus LBX's compact size, almost every inch of the car can be seen from the steering wheel, adding to the confidence, comfort and control the driver enjoys with the Lexus Driving Signature. The contouring of the bonnet and the shape and position of the front pillars reduce the blind sports and give an extended downward view that helps the driver steer more precise lines.

To help maintain a wide, clear view, the horizontal instrument panel has a clean and simple design. At each side, its form flows into the door panel, giving a sense of wrapping around the front seat occupants, so the feel is expansive yet encompassing. The continuous line created by this design also helps the driver sense the degree of vehicle roll when driving through bends. A low hip-point adds to the driver's sense of being at one with their car, while ample front knee-space is provided. To ensure a good view out for everyone on board, the rear seats are set slightly higher than those at the front.

The centre console has a strong presence with the large multimedia touchscreen tilted back so that it integrates smoothly with the structure. The unit has upholstered side pads and houses two cupholders and multiple storage points and USB ports for device connection and charging. The load compartment offers up to 332 litres (FWD models with rear seats in place) of space - room enough for two 75-litre cases to be carried beneath the folding tonneau cover.

MULTIMEDIA AND INFOTAINMENT

The LBX is equipped with the latest Lexus Link Connect system, operated via a 9.8-inch touchscreen.

The system provides cloud-based navigation, optimising journey planning with real-time information on traffic events and delays. Further convenience is provided by the "Hey Lexus" on-board assistant which responds to voice commands from both driver and front seat passenger.

Smartphone integration is enabled using wireless or wired connections for Apple CarPlay, or a wired link for Android Auto. Further convenience is provided by an optional digital key. Compatible with both Apple and Android smartphones devices, this allows owners to use their smartphone to unlock and start their car. They don't have to take their phone out of their pocket or bag, just having it on their person is sufficient. They can also share the digital key when other people need to access or use the vehicle.

In common with the latest new Lexus models, the LBX offers seamless over-the-air software updates for its multimedia and safety systems, so owners can benefit from upgrades without having to organise a visit to a Lexus workshop.

Mark Levinson, Lexus' exclusive audio partner, has designed an optional premium system for the car, featuring an array of 13 optimally positioned speakers. They include a subwoofer integrated in the back door, avoiding any loss of space in the load compartment.

MODEL RANGE: INTRODUCING LBX ATMOSPHERES

With the LBX, Lexus is taking a new approach to building a model range, to better match customers' preferences and lifestyles.

The line-up offers a choice of four model "atmospheres" in addition to the base grade: Elegant and Relax which focus on a refined feel, and Emotion and Cool which have a sportier, more dynamic character. Each has been designed with a different type of customer in mind.

Emotion and Cool models stand out with bi-tone paintwork and 18-inch alloy wheels with a machined finish. The Elegant and Relax versions have a monotone exterior paint finish and glossy 18-inch alloys.

Where the interior specifications are concerned, the Emotion model comes with perforated synthetic leather upholstery with red accents and contrast stitching on the seats, centre console and door trim. The LBX Cool - the top dynamic-themed model - has an Ultrasuede and leather bi-tone black/dark grey interior with copper details and stitching.

Different moods are evoked by the Elegant and Relax atmospheres. Synthetic leather in a subtle Forest Brown shade or Ammonite Sand features in the LBX Elegant, for the door panels, instrument panel and console pads as well as the seat upholstery. For the Relax model, the choice is Saddle Tan or Black semi-aniline leather with distinctive Tatami stitching.

In addition to the four atmosphere models there is an entry level LBX which, comes with advanced technology features as standard rather than extra-cost options, in contrast to some competitor models. Notably these include the extensive active safety and driver assistance systems included in the latest generation Lexus Safety System +. The entry model and the Emotion and Elegant versions can be specified with a vegan-friendly interior with no leather products.

Equipment option highlights include a 12.3-inch Tazuna concept digital instrument display, head-up display, remote parking, digital key, Mark Levinson premium surround sound audio, Panasonic's nanoe™-X air purification technology and a power back door.

Lexus Bespoke Build

Owners who wish to give their LBX a more personalised look can take advantage of the new Lexus Bespoke Build service. Lexus' customer-first approach gives them the freedom to personalise their vehicle with tailor-made details.

The bespoke treatment allows customers to change the colour of the seatbelts and the upholstery embroidery patterns and stitching colour and the trim ornamentation. The choice of luxury materials includes L-aniline leather - a prestige leather only available on LBX and the flagship LS sedan within the Lexus range - and Ultrasuede in different colour combinations. This personalisation service will be introduced in selected markets after the start of LBX sales in 2024.

SAFETY AND DRIVER ASSISTANCE

The Lexus LBX benefits from the comprehensive safety and driver assistance provisions of the latest generation of Lexus Safety System +. This equips the car with multiple systems to detect accident risks, alert the driver and automatically provide steering, braking and drive force control if required to help avoid or lessen the consequences of a collision. Key elements include a Pre-Collision System with Intersection Turn Assist, Dynamic Radar Cruise Control, Lane Tracing Assist/Lane Keep Assist and Road Sign Assist. Additional items that support safer driving and manoeuvring and reduce the burden on the driver include Lexus' e-latch electric door release system with Safe Exit Assist, a driver monitor, intelligent parking sensors with auto-braking, Rear Cross Traffic Alert and a Blind Spot Monitor.

An extended safety will be optionally available, introducing features such as a Front Cross Traffic Alert system and a Panoramic View Monitor. A remote parking option can take all the stress out of manoeuvring the car into a tight space; it even allows the driver to park their vehicle remotely, using their smartphone.

The driver enjoys better visibility in poor weather conditions with a new wet arm wiper, as featured previously on Lexus' flagship LC and LS models. This distributes washer fluid from the wiper itself, giving more thorough and immediate windscreen cleaning performance.

The Lexus LBX is an all-new model for a new market for Lexus in Europe. It is set to be a game changer and key model for the brand's growth in the region.

The smallest Lexus yet, the LBX is a self-charging hybrid electric crossover that's designed to be accessible and easy to live with, in tune with contemporary style thinking that combines high quality with a casual feel. It offers much more than might be expected from a car in its class, embracing advanced technologies and making no compromise in the distinguishing Lexus qualities of luxury craftsmanship and Omotenashi hospitality for everyone on board.

For the first time, Lexus has focused the development of a vehicle specifically on addressing the preferences, tastes and trends of the European region. The LBX will immediately become a core model brand's line-up, with 24,000 sales targeted in Europe in 2024.

The use of a three-letter name is significant - previously only the LFA supercar has enjoyed that distinction. The choice of the name LBX demonstrates Lexus' commitment to and trust in its new model. Just as the LFA showed a different side to the brand in terms of attitude and performance, so the LBX will challenge the status quo and redefine what a small car can offer, energising and expanding the brand's reach and profile.

As a new entry point to Lexus' European model range, it offers strong appeal to a younger audience and those who may not have considered a Lexus before. It will also be an attractive proposition to those seeking to downsize or purchase a second vehicle, meeting their evolving lifestyle requirements.

Chief Engineer Kunihiko Endoh comments: "Our aim was to challenge the conventional concept of a luxury car. We have thoroughly pursued a driving experience that enables a natural dialogue between the driver and their vehicle and a design that has a refined presence."

The driving experience is central to the LBX's customer appeal and extensive efforts have been invested to ensure the constant control, comfort and confidence of the Lexus Driving Signature are delivered in a small car package. The package of fundamental measures includes fundamental revisions to the GA-B global platform, lengthening the wheelbase, widening the track and increasing body rigidity. Packaging, suspension tuning, braking and steering all play their part in producing a car that responds instantly and faithfully to the driver's inputs.

The new powertrain, a self-charging 1.5-litre hybrid electric system, is tuned for rewarding performance, with powerful, linear acceleration from start-up. This helps deliver low-speed agility that's well-suited to the demands of urban driving. A new bi-polar nickel-metal hydride hybrid battery provides greater responsiveness from a smaller and lighter package, while extensive measures to address road noise and vibration ensure the kind of calm and quiet on-board experience appropriate for a premium model.

The Lexus LBX's styling establishes a new Lexus identity with a "Resolute Look" front design that reinterprets the famous spindle grille. While the exterior dimensions are more compact than any other Lexus, the look is muscular and powerful. Inside, the emphasis is on driver-engagement with a focused driver's cockpit based on Lexus' Tazuna concept. Inspired by a rider's precise use of the reins to control a horse (the meaning of Tazuna in Japanese) controls and information sources are arranged so that only small movements of hand and eye are required for operation, keeping the driver's attention focused on the road. The cabin has a light, open feel with excellent visibility and an instrument panel that wraps around smoothly into the door panels.

In doing things differently with the LBX, Lexus has taken a new approach to building a model range, introducing choices that better reflect how today's customers seek cars that match their personal style and character.

It is disrupting the traditional linear grade strategy to give owners more freedom to express their individual taste and sense of style. True to Lexus' commitment to "making luxury personal," the LBX will be offered in a choice of four "Atmospheres" together with a generously specified entry model. Rather than being defined by the level of equipment or comfort features, these atmospheres focus on expressing different refined, dynamic or sporty themes through styling details, colours, textures and finishes. A new Lexus Bespoke Build programme, available for ordering from January in selected countries, will offer yet more personalised options.

The LBX is the first Lexus model to be manufactured at the Iwate plant in eastern Japan, a facility that has benefited from Toyota Motor Corporation investment to help regenerate a region that suffered devastation from the Tohoku Earthquake and Tsunami of 2011. Production will begin within this year; deliveries to customers in Europe will begin in early 2024.

THE LBX AND THE EUROPEAN MARKET

In developing the LBX specifically to appeal to contemporary European tastes, Lexus identified three key customer profiles: existing Lexus customers who want a second, smaller car; people who admire the Lexus brand and what it stands for, but have not yet found a model that suits their needs; and those who haven't considered Lexus before, but whose interest will be triggered by the new crossover.

These consumer types will be attracted principally by the Lexus LBX's eye-catching exterior design, the premium look and feel of its cabin - a sense of "one segment up" quality - and the performance and efficiency of the self-charging hybrid electric powertrain.

Personalisation is another asset, with Lexus giving owners the chance to tailor their car to their individual style with the introduction of the new Atmospheres interior styling options. Going further, Bespoke Build allows for even wider range of personal preferences to be catered for, in a service that's more usually the preserve of top-of-the-range models. These measures reflect Lexus' approach to "making luxury personal" and are pivotal in setting the car apart from its class competitors.

To help customers visualise how different option combination would look, Lexus has launched an online car configurator. This provides a virtual 3D, 360-degree introduction to the LBX, as though you are exploring an actual car, opening the doors and stepping inside to experience the design and the range of different colours, interior trims and features.

The launch model range includes an Original Edition, a top-of-the-range, high-specification version, limited to just 2,000 examples for the first European customers. Based on the LBX "Cool" Atmosphere, its bespoke features include a bi-tone exterior paint finish with exclusive Sonic Copper colour-way, matt black 18-inch alloy wheels, stylish exterior trim details and Original Edition badging and leather and Ultrasuede upholstery with black stitching detail.

The introduction of the new LBX gives Lexus a European model range that extends from this all-new crossover through luxury sedans, SUVs, people carriers and flagship limousines, coupes and convertibles. And even though this is the most compact model in the line-up, owners will still receive the industry-leading Lexus customer experience.

EXTERIOR DESIGN

Lexus has rewritten its own rule book in developing the all-new LBX urban-friendly crossover, not least in rethinking some of its most familiar design conventions.

This radical new self-charging hybrid electric model has styling that sets it apart from its larger stablemates and signals its intention to capture the hearts and minds of a new breed of customer for the brand.

LIFE ON BOARD

Lexus designers sought to create a simple and refined interior that creates the feel and atmosphere of a higher segment model. This effect is founded on three key elements: good visibility with an open view out and an uncluttered, smooth instrument panel; the sense of wide interior space; and a centre console with a commanding presence.

Throughout, the cabin expresses the Lexus Omotenashi approach to making those on board feel welcomed and comfortable, with design details that anticipate their needs - from lighting and climate control, to the design and adjustment of the seats, the response of the multimedia system and the E-latch electronic door release system.

The driver's cockpit is an interpretation of Lexus' Tazuna concept, first introduced on the NX mid-size SUV. This positions principal controls and information sources immediately around the driver, so operation or reading only requires minimal movements of hand or eye, helping keep the driver focused on the task of driving, with least distraction.

To help maintain a wide, clear view and open cabin feel, the horizontal instrument panel has a clean and simple design. At each side, its form flows into the door panel, giving a sense of wrapping around the front seat occupants, so the feel is expansive yet encompassing. The continuous line created by this design also helps the driver sense the degree of vehicle roll when driving through bends.

DYNAMIC PERFORMANCE

Driving performance was a focus point for development of the LBX. Lexus' ambition was to deliver the Lexus Driving Signature in a small car package, engineering a vehicle in which the driver feels confident, comfortable and in control at all times. Prompt, faithful steering, braking and throttle responses and stable handling in all conditions generate a natural dialogue and constant sense of connection between driver and car.

Chief Engineer Kunihiko Endo explains: "We worked on achieving a nimble drive that maximises the benefits of the LBX's small size and light weight, while focusing more than ever on honing the car's fundamental characteristics, without relying on electronic controls."

This involved measures such as lowering the centre of gravity, widening the track to enhance inertia specifications, making the body more rigid, reducing weight, using larger, wider tyres and revising the suspension. These all combine to ensure the car moves faithfully and responsively in line with the driver's intentions.

POWERTRAIN

The LBX has a new self-charging full hybrid electric powertrain that is both highly efficient and tuned for the kind of prompt, responsive acceleration that's characteristic of battery electric power. It's a key element in giving the Lexus LBX a rewarding driving character and securing the all-round rewards of the Lexus Driving Signature.

The total system output is 136 DIN hp/ 100 kW with peak torque of 185 Nm, giving 0-100 km/h acceleration in 9.2 seconds for the front-wheel drive model, 9.6 with all-wheel drive. Official WLTP combined cycle figures indicate fuel economy from 4.4 l/100 km and CO2 emissions from 100 g/km.

1.5-litre VVT-iE engine

The 1.5-litre three-cylinder engine has world-class thermal efficiency, supported by high-speed combustion, achieved with technologies evolved from Formula 1 engineering, including a longer stroke, increased valve angle and laser-clad intake valve seats. The Ultra-lightweight pistons are designed for performance at high engine revs and have a resin skirt coating that reduces friction with the cylinder wall.

Further thermal efficiency is gained from a variable cooling system that adjusts the coolant flow rate according to the engine's running conditions and the outside temperature. This achieves quicker engine warm-up and reduces friction losses, contributing to fuel economy and supporting efficient air conditioner performance.

Electronic, intelligent variable valve-timing on the intake side - VVTi-E supports a good balance between fuel economy and power response, even at low engine speeds or with low oil temperatures.

Hybrid transaxle

Lexus' small-capacity hybrid system uses a new transaxle, designed to save weight and space. Nonetheless, it delivers 17% higher output than conventional units of the same size, with class-leading fuel consumption, quiet running and low emissions.

Artificial Intelligence tools were used together with Model Based Development (MBD) and precision measurement in the transaxle redesign to reduce the size of the geartrain and achieve a shorter transaxle unit. Further space is saved by the two motor-generators being located on separate shafts. Every element was scrutinised for ways size and weight could be reduced without sacrificing performance or quality. Details include new gear tooth design, lubrication and cooling mechanisms, casing design and the use of low-viscosity oil.

The new power control unit (PCU) is sufficiently compact to be mounted directly above the transaxle, helping secure a low bonnet line and consequently supporting both fuel efficiency and pedestrian protection performance.

New bi-polar hybrid battery

The Lexus LBX follows the all-new RX to become the second Lexus model to benefit from a new high-output bi-polar nickel metal hydride (NiMH) hybrid battery.

The innovative bi-polar technology allows for a higher power density to be achieved from a more compact and lighter battery unit. Response delay is reduced by half, which contributes to nimble, exhilarating performance, giving the kind of high torque delivery at low speeds that's normally associated with pure electric vehicles. When braking, there is a faster power regeneration. It also benefits from a redesigned cooling system to help prolong battery life and performance.

The entire battery pack is accommodated beneath the rear seats, avoiding any loss of cabin or load space.

Hybrid Control System

The Hybrid Control system harnesses the increased electric motor and hybrid battery output to deliver sharp response at start-off and a feeling of continuous acceleration. Compared to previous hybrid systems, responsiveness has been increased by about 30% and initial acceleration by around 20%; acceleration is sustained, without the feeling of a drop off in momentum.

The system also supports rewarding performance by assisting acceleration and deceleration force when driving on inclines, so there's less need to use the throttle when travelling uphill, or the brakes when going downhill.

With the hybrid battery contributing more power at start-up, engine revs are around 20% lower, so there is a more pleasing, linear relationship between the driver's use of the accelerator and the engine sound.

The system detects when the car begins to travel downhill and automatically implements deceleration control, even when the driver comes off the brake pedal.

Predictive Efficient Drive

Predictive Efficient Drive predicts driver behaviour and road and traffic conditions to optimise hybrid battery power charging or discharging in line with the actual driving situation. This intelligent operation helps enhance fuel efficiency. It works in conjunction with the car's cloud-based navigation, gathering data when following a route regularly used by the driver; it can be switched on or off as the driver prefers.

Predictive Deceleration Support recognises locations on the route appropriate for deceleration support and shows them as icons on the navigation screen. As the car approaches the support point, regenerative braking is increased to support the driver (this function operates even when navigation route guidance isn't being provided). The increase in regenerative braking also provides more efficient battery charging.

The system uses Predictive State of Charge Control (SOC) during route guidance to pinpoint areas such as an uphill gradient or traffic congestion up to 10 km ahead and determine efficient battery charging or discharging. For example, Downhill SOC control will make use of battery charge before reaching a downhill route section, so the opportunity to recover energy isn't wasted. Congestion SOC control proactively charges the battery before reaching traffic congestion, using information from live traffic reports. This potentially reduces the number of times the engine will have to start when moving in slow traffic.

Sequential Shiftmatic

Sportier versions of the Lexus LBX - Relax and Cool grades and Bespoke Build models - are equipped with a Sequential Shiftmatic system which lets the driver select the shift range using paddle controls on the steering wheel.

The system delivers highly responsive engine braking force in six steps, giving a shift feel similar to using a manual transmission and thus increasing the driver's sense of engagement with the car, particularly when following winding country routes.

E-Four all-wheel drive

The driver can gain extra confidence from safe and stable performance when cornering or pulling away in low-grip conditions with the option of Lexus' E-Four all-wheel drive. This introduces an additional electric motor on the rear axle and automatically directs an appropriate level of drive force to the rear wheels. The compact, fuel-efficient system can vary the ratio of front to rear-wheel drive torque from between 100:0 to 20:80.

SAFETY AND DRIVER ASSISTANCE

In addition to features such as the Advanced Park system and Vehicle Braking Posture Control detailed above, the LBX is equipped as standard with the comprehensive safety and driver assistance provisions of the latest generation of Lexus Safety System +. This equips the car with multiple systems to detect accident risks, alert the driver and automatically provide steering, braking and drive force control if required to help avoid or lessen the consequences of a collision.

The Pre-Collision System (PCS) provides an increased detection range with a new combination of front radar and camera sensor. Its operational scope includes being able to recognise motorcycles and oncoming vehicles. Its Intersection Assistance is also enhanced, to include detection of oncoming vehicles and cross pedestrians when making a turn at a junction.

The system further benefits from Emergency Steering Assist which helps keep the car stable and within its traffic lane when the driver needs to avoid a parked car, pedestrian or other obstacle to the side of the road. The system is also available with Active Support, which works to avoid a collision by providing gentle braking and steering.

The PCS also provides Low Speed Acceleration Suppression, recognising sudden, unintended use of the throttle when driving at low speed. The optional Front Cross Traffic Alert warns the driver of approaching vehicles from either side, helping the driver at junctions with poor or compromised sight-lines.

Dynamic Radar Cruise Control (DRCC) provides a wide range of inter-vehicle distance settings, so the driver can tailor performance to their personal preference.

Functions include Curve Speed Reduction, ensuring an appropriate speed for smooth driving through bends, and Overtaking Prevention, which regulates the car's speed to avoid overtaking a slower vehicle on the wrong side on a multi-lane road. The driver can also easily reset the cruising speed to comply with changes in the speed limit detected by the Road Sign Assist system (RSA).

The Lane Departure Alert (LDA) has been enhanced to recognise more objects, including adjacent street furniture such as utility poles, kerbstones and guard rails. It can also recognise when the driver is steering to avoid a person or parked vehicle in the LBX's traffic lane.

The high-performance camera used by the Lane Tracing Assist (LTA) is better able to distinguish road markings; when markings are obscured, for example in heavy traffic, the system will follow the path of the vehicle ahead. It can also recognise 3D objects so can adjust its performance to give appropriate lateral clearance from vehicles in adjacent lanes or roadworks, operating in way that feels natural to the driver.

Lane Change Assist can be used when the car's LTA is activated. When the driver signals to make a lane change, the system checks for safety using the PCS radar and camera, calculates the target trajectory and provides appropriate steering control. Once the lane change is complete, LTA returns to its normal operating status.

The Driver Monitor is a camera mounted above the steering wheel which keeps a constant check on the driver's condition. If it recognises that they have lost concentration through being tired or unwell, it triggers visual and audible alerts. The system is linked to the car's active safety systems, so that should the driver fail to respond, the car can be brought smoothly to a controlled halt with the hazard lights activated (Emergency Driving Stop).

Proactive Driving Assist (PDA) includes Obstacle Anticipation Assist, Deceleration Assist and Steering Assist. The system operates at lower speeds, for example when driving around town. The front camera scans the area ahead of the car to check for hazards such as pedestrians about to cross or walking along the side of the road, parked cars and cyclists. If there is a collision risk, the system will provide braking and steering to avoid the obstacle, while keeping the car in its traffic lane.

The Lexus Safety System + package also provides Automatic High Beam or, on higher specification models, an Adaptive High-beam System for automatic adjustment of the headlight beams to achieve optimum forward illumination without dazzling oncoming traffic.

Road Sign Assist (RSA) can recognise and display a wider range of highway warning and command signs. The car's speed limiter can be linked to the RSA, reducing powertrain output and applying braking if necessary to keep the car within the legal speed limit for a given road.

Help when making manoeuvres is provided by the Rear Cross Traffic Alert and Blind Spot Monitor, together with a Reversing Camera and a Parking Support Brake. The Parking Support Brake automatically applies drive force and braking control if there is a risk of contact with a static object, vehicles approaching from the rear or pedestrians, when moving at low speed.

Wet arm wiper

The driver gains better visibility in poor weather conditions with a new wet arm wiper, as featured previously on Lexus' flagship LC and LS models. This distributes washer fluid from the wiper itself, giving more thorough and immediate windscreen cleaning performance.
