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 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.

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 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.
