Lexus: Electric Drive Control and Outlook on 2021 Models

The Japanese Toyota subsidiary Lexus is pushing its electrification in parallel with the group and has provided a preview of the core technology for the next generation of its electric and hybrid vehicles with the electric drive control system named DIRECT4. The system is intended to ensure precise and demand-driven distribution of torque and braking force to all four wheels, providing the basis for high performance, driving safety, and handling characteristics. Last year, the manufacturer presented the futuristic concept vehicle LF-30 at the Tokyo Motor Show. This allows the drive of the front and rear wheels to be adjusted to the respective driving conditions and the driver's intentions. The system includes an e-axle at the front and rear, each with a high-torque electric motor and gearbox. Since the motor is directly connected to the wheels via a single drive shaft, the manufacturer promises a delay-free drive with optimal power distribution. Furthermore, Lexus promises a "balance of predictability and driving pleasure with powerful, smooth acceleration and dynamic cornering behavior."
