Lexus has revealed a new electric drive control system DIRECT4, designed to achieve unique dynamic performance - the Lexus Driving Signature - for the luxury lifestyle brand's next generation of battery electric and hybrid electric vehicles.
DIRECT4 precisely controls the delivery of drive torque from front and rear electric motors and braking force to all four wheels.
By automatically adjusting the balance of front and rear-wheel drive, the system adapts the driving conditions to the driver's intentions, changing the driving feel and giving the car the best driving posture.
The system uses a front and rear e-axle, each featuring a high-torque electric motor and transaxle, focusing on optimum drive force distribution. As the motor is directly connected to the wheels by a single driveshaft, it operates without delay.
Its operation is intuitive and highly responsive, giving the driver a genuine sense of being fully connected with the vehicle. Moreover, it provides an ideal balance of predictability and excitement, with powerful, linear acceleration and exhilarating cornering.
At the same time, the system is engineered for quietness and comfort, true to the core quality of Lexus vehicles.
