All-New Lexus NX Premieres, Heraldling the Start of the Lexus Next Chapter
Lexus NX (Prototype)
Lexus announced the world premiere of the all-new NX, the first model of Lexus’ next-generation range. The NX, as well as the forthcoming model lineup, will better meet the diversifying needs and lifestyles of customers the world over, and in doing so, will promote the realization of a carbon-neutral society.
Since its establishment in 1989, Lexus has been committed to the spirit of innovation and has continued to take on the challenge of providing new technologies and values to its customers. With the launch of the first-generation RX in 1998, Lexus created a new category of luxury crossover SUV and has been a leader in the realm ever since. In 2014, Lexus launched the NX, based on the concept of ‘Premium Urban Sports Gear.’ Since then, the luxury crossover has been well-received by customers for its agile driving performance and powerful design. As of the end of April 2021, the NX has sold a cumulative total of approximately 1 million units in more than 90 countries and regions, and together with the RX, has grown to become a core global model for Lexus.
The new NX is the first model to introduce the next generation of Lexus and is based on the development concept of ‘Vital x Tech Gear.’ This concept combines vital dynamism (Vital) with advanced technology (Tech). The new NX features improved linear response thanks to the strengthening of the car’s fundamentals, a design that attracts attention with athletic proportions, and many advanced, new technologies. Also, in order to establish the unique driving experience to be found in future electrified vehicles, Lexus focused on thoroughly improving driving control, aerodynamics, and weight reduction. In addition, based on the ‘Lexus Electrified’ electrification vision, the new NX will be available as both HEV and―a Lexus first―PHEV, further accelerating the rollout of electrified vehicles. In addition, Lexus will respond to the diversifying needs of customers by offering a wide lineup of powertrains, including models powered by a 2.5-liter naturally-aspirated or a 2.4-liter turbocharged engines, among others.

‘The development of the new NX was a series of new challenges for Lexus. We implemented ‘digital development’ to ensure quality by evaluating the well thought-out design structure under various conditions using computer models to check productivity. In terms of driving, professional racing drivers conducted an evaluation test drive at the Shimoyama test course to thoroughly train the car’s body structure and control the driving force to inherit and evolve the Lexus driving flavor.
The powertrain lineup is diverse, including Lexus’ first PHEV, a newly developed 2.4-liter turbocharged engine, and a newly developed electronically controlled full-time AWD, as well as a number of advanced technologies and a new generation of multimedia. The attractive design and performance of our products have been achieved through the cooperation of our suppliers and many innovations in production technology. Planning, development, production engineering, and manufacturing are connected online across national borders in a difficult environment such as limited mobility, and for the first time for Lexus, production will be carried out at three locations around the world. All of this has been done with the full force of our team working together for the smiles of our customers. We hope you will experience the challenge of the new generation of Lexus and the new NX that we, the development team, have poured our passion into delivering.’

Based on its ‘Lexus Electrified’ electrification vision announced in 2019, Lexus aims to continue providing customers with the enjoyment and pleasure that cars bring, even in this era of ever-changing mobility society. Doing so will necessitate the evolution of its vehicles’ basic performance. Lexus will therefore accelerate the spread of electrified vehicles (along with HEVs) by introducing the brand’s first PHEV powertrain in the all-new Lexus NX. The global core model will offer a practical EV range, powerful acceleration performance, and superior quietness.
The plug-in hybrid system used in the PHEV version of the NX is equipped with a thermally-efficient 2.5-liter inline-four engine, a high-capacity, high-output lithium-ion battery, and front and rear motors. The lithium-ion battery has an impressive power output of 18.1 kilowatt-hour (kWh), providing a class-leading EV range and power for daily driving. The driver can alternate at will among four driving modes (EV mode, AUTO EV/HV mode, HV mode, and Self-charge mode) at the touch of a switch. In HV mode, the engine and motor work together to achieve high acceleration performance. In addition, when AUTO EV/HV mode is selected with a destination inputted into the navigation system, Lexus’ first anticipatory EV/HV mode will automatically switch to HV mode on highways and other road conditions based upon data such as remaining battery power, route, and traffic information, all for the achievement of energy-efficient driving.
The new NX uses the GA-K platform to achieve a lightweight, highly rigid body with a low center of gravity to enable superior handling. The basic performance of the vehicle has been greatly improved, and it inherits Lexus’ unique driving signature, which is faithful to the driver’s inputs with control surfaces tuned for a more linear response. In addition, seven powertrains, including Lexus’ first PHEV, have been introduced to offer a suitable global range of drivetrains that help realize a driving experience that seamlessly blends comfort, stability, athleticism, power, and safety. Driver connection, control, and confidence are elevated in all conditions thanks to the Lexus Driving Signature tuning philosophy.
Lexus’ first PHEV features AWD (E-FOUR) with constantly variable front-to-rear torque distribution between 100:0 and 20:80 percent modes. The high-capacity lithium-ion battery is placed under the floor to lower the center of gravity and help enhance handling and the overall driving experience.
The HEV also combines a highly efficient 2.5-liter inline-four engine with a high-output electric motor, and uses a control logic exclusive to Lexus to achieve an optimized balance of acceleration performance and reduced fuel consumption. E-Four has a constantly variable front/rear driving force distribution from 100:0 to 20:80 percent modes. A FWD version will also be introduced to meet the diversifying needs of customers.
A newly developed 2.4-liter inline-four turbocharged engine, a newly developed high-torque Direct Shift-8AT, and a newly developed electronically controlled full-time AWD. In addition to the Toyota New Global Architecture’s (TNGA) high-speed combustion system, the engine features Lexus’ first center-injection direct-injection system and a close placement of the turbocharger and catalyst done in order to meet increasingly stringent exhaust and fuel economy regulations around the world, while at the same time being conscious of carbon neutrality. The transmission has been optimized for the turbocharged engine, which can generate high torque from low rpm. The newly developed shift control technology enables acceleration and deceleration that is faithful to the driver’s will and provides a pleasant shift schedule. Additionally, the electronically controlled full-time AWD constantly varies the front/rear driving force distribution from 75:25 to 50:50 (depending on situation), and uses unique technology to achieve both an optimal contact patch and linear steering feel.
A highly efficient 2.5-liter inline-four engine and Direct Shift-8-speed AT. The AWD system has a constantly variable front/rear driving force distribution ranging from 100:0 to 50:50, with the same unique control technology and optimized final gear ratio as the 2.4-liter engine, providing sufficient driving force and a pleasant driving experience with an optimal and rhythmic shift schedule depending on the situation. A FWD model will also be introduced to meet the diversifying needs of our customers.
Lexus NX (Prototype)
The newly developed NX suspension uses MacPherson struts in the front and a trailing arm, double-wishbone design in the rear. The newly developed shock absorber maintains damping force at low speeds by careful design of high friction parts. The F SPORT is equipped with the latest Adaptive Variable Suspension (AVS) as standard equipment to achieve both high levels of maneuverability and ride comfort. The wheel fastening structure has been changed from stud bolt and hub nut fastening to hub bolt fastening. By increasing rigidity and reducing unsprung weight (approx. 0.7kg less than when the hub nut is fastened), it contributes to a clean and responsive steering feel and a high quality ride. The 20-inch and 18-inch tires are equipped with Extended Mobility Tire (EMT)*3 to provide a high-quality ride while ensuring the ability to drive a safe distance in the event of a puncture. The steering adopts Lexus’ first variable rack gear*4 to enhance stability at high speeds and enable a quick cornering response. The new variable rack steering gear also excels at low speed handling. For braking, a new ergonomically-shaped brake pedal pad has been developed for easier switching between pedals and easier brake pedal depression. The PHEV and HEV are the first Lexus vehicles to feature a pedal return damping mechanism, enhancing the dynamic quality of the pedal release operation. In addition, a faster reacting, revised brake actuator better supports the function of the Lexus Safety Sense +.
AERODYNAMIC PERFORMANCE
Aerodynamic Performance (Image)
Thorough attention was paid to aerodynamic control and safety technology. Flush belt moldings with minimal steps from the door design surface to the glass surface are used to optimize over-body air flow and improve handling stability. On the underside of the vehicle, the dimples in the underbody engine splash shield generate micro-vortices that help enhance under-body airflow and contribute to driving stability at high speeds. The front bumper is shaped for improved air-flow and downforce, and the rear bumper has an opening to balance rear suspension movement.
Aiming to achieve quietness befitting a Lexus, in addition to optimizing sound-absorbing and sound-insulating materials in various parts of the vehicle to reduce noise entering the cabin, the air flow and wind noise seeping into the cabin has been dramatically reduced (approximately 15% reduction compared to previous sound pressure level). Furthermore, in an effort to mitigate high speed wind noise, a revised weather strip and front door glass run shape have been developed to improve door sealing. For the front door glass, a new sound insulation material has been adopted*4. The engine hood uses a twin-lock structure, a first for Lexus, to suppress engine hood vibration caused by air turbulence, contributing to improved quietness. The 2.4-liter turbocharged model features Active Noise Control/Engine Sound Enhancement, which enhances the noise characteristic of the four-cylinder turbocharged engine, while producing a pleasant driving experience with a pleasing sound typical of Lexus.

In an effort to further evolve the next generation Lexus design language, the new NX distinguishes itself by focusing on vehicle proportions that enhance an athletic image and align with the model‘s driving performance, function, and the clean simplicity of the new crossover’s technology. For the exterior, changes to the platform have resulted in an expressive, dynamic shape defined by softer angles and more organic forms. The interior is focused on creating a welcoming, hospitable space for each occupant and, for the first time, fully incorporates the Tazuna Concept. This human-centered cockpit philosophy enables a more seamless and intuitive connection between the driver and car to help enhance concentration on driving.
DYNAMIC FRAMEWORK AND INCREASED REAR SEAT SPACE BY ADOPTING A NEW PLATFORM
The front and rear tires have been enlarged from 225/60R18 inches to 235/50R20 inches, and the front and rear treads have been widened to enhance the NX’s dynamic image. In addition, by lowering the hip point of the rear seat, passenger head clearance has been increased to improve rear-seat occupant comfort.
PROPORTIONS THAT EXPRESS THE UNIQUENESS OF LEXUS
The familiar Lexus spindle architecture has been deepened with a three-dimensional design that starts from the spindle grille and extends significantly toward the rear fenders. In addition, we pursued the uniqueness of Lexus by creating a vehicle shape in which the front fenders’ upward-flowing three-dimensional forms merge with those near the rear fenders.

In order to realize the ultimate wish of the mobility society – ‘zero fatalities and injuries in traffic accidents’―the NX adopts the evolved Lexus Safety System +. By expanding the detection range of the millimeter wave radar and monocular camera, we have enhanced the performance of each function and added new functions to assist on ordinary roads. The aim is to prevent accidents, further reduce traffic fatalities and injuries, and ease the burden on drivers.
In addition, the NX is equipped with Advanced Park, an advanced driving support technology developed based on the Mobility Teammate Concept, to support safe, secure and smooth parking. Furthermore, a new function has been added to allow remote parking using a smartphone. In addition, automatic door-opening cancellation (Safe Exit Assist), which is linked to the Blind Spot Monitor sensor and e-latch system, supports safe and secure exit. For added convenience, a digital key that allows the driver to operate the car from a smartphone is also available.
THE LATEST LEXUS SAFETY SYSTEM + WITH EXPANDED FUNCTIONS AND ENHANCED PERFORMANCE
PRE-CRASH SAFETY PCS*1
Assistance at intersections has been expanded to include assistance in avoiding collisions with intersecting vehicles, oncoming vehicles coming straight ahead when turning right*2, and pedestrians and bicyclists approaching from ahead when turning right or left. In addition, the scope of assistance has been expanded to include motorcycles, oncoming vehicles that have deviated from their lane, and bicyclists at night. When the system determines that there is a high possibility of a collision, it will activate the alarm and brakes to help mitigate the damage.
The aim is to control the system in cooperation with the driver, for example, by deactivating the lane departure warning and restraint functions when it can be judged that the driver has made a deliberate maneuver to avoid a person or parked vehicle. In addition, the system newly recognizes utility poles, curbs, guardrails, walls, and continuous poles, enabling additional support at lower speeds.
The lane recognition performance has been enhanced to realize smoother and less disruptive steering support. In situations such as overtaking a vehicle in the adjacent lane, or when there is a close distance between the vehicle and an off-road structure, the tracing position is offset from the center of the road to the avoidance side, just like the driver’s driving, in order to achieve cooperative control with the driver.
When driving on highways and motor-vehicle-only motorway (excluding some areas) while Lane Tracing Assist is activated, the operation of the turn signal activates lane changing support, in the form of the system confirmation of the area surrounding the vehicle, steering assist, and the monitoring of vehicles in the targeted lane.
In addition to the existing ‘maximum speed,’ ‘no overflow,’ ‘no vehicle entry,’ and ‘temporary stop’ signs, we have expanded the scope of support to include ‘no turning’ signs.
In addition to the conventional warning function for the vehicle in front of you, we have added a new function that notifies you with a display on the meter and head-up display, as well as a buzzer, if your vehicle continues to stop even after the stop sign at the beginning of an intersection is lifted (including an arrow signal in the same direction as the vehicle’s turn signal).
Proactive Driving Assist
By anticipating risks according to the driving situation, such as ‘pedestrians crossing the road’ or ‘vehicles may run out of control,’ the system supports the driver to avoid getting too close to danger, leading to peace of mind for the driver. In addition, the system supports the driver’s deceleration in response to a vehicle ahead or a curve ahead, and reduces the need for frequent changes in pedal application.
Proactive Driving Assist
When exiting the vehicle, the system uses the sensors of the Blind Spot Monitor [BSM*15] to detect vehicles approaching from behind, including bicycles. If the system determines that there is a possibility of a collision with an open door or an alighting occupant, the indicator in the outer mirror will light up to alert the driver. In addition, if the driver tries to open the door, the system cancels the door opening in cooperation with the e-latch system. The world-first*14 system notifies the occupants with a buzzer, flashing indicator in the outer mirror, display on the meter, and voice notification.
The support situations have been expanded to include in perpendicular parking situations, forward parking, backing out of a parking space, and pulling out of a parking space. In addition, by operating a smartphone with a special application installed from outside the vehicle, the driver carrying a smart key can remotely parallel park, parallel park, and exit the vehicle. The system also supports forward and backward movement when removing luggage from the trunk.
By installing a special application on the smartphone, the smartphone can be used as a key for vehicles that have this function. If you carry a smartphone, you can lock, unlock, and start the engine without operating the screen, and even if you own several cars that are compatible with the digital key, you can operate them with only one smartphone. Digital keys can be handed over between smartphones, making it easy for family and friends to borrow and lend vehicles remotely.
The Panoramic View Monitor, which combines images from cameras mounted on the front, rear, left and right sides of the vehicle and displays them on the center display, has a new function to display images of the road surface taken in the past directly underneath the vehicle to help the driver understand the road surface and tire position underneath the vehicle.
