How does DIRECT4 Lexus all-wheel-drive work? | Lexus RZ 450e



The all-new, all-electric Lexus RZ 450e is the first production model to feature Lexus’s new DIRECT 4 system.

Working with the two e-Axles. DIRECT4, an exclusive Lexus technology, is an intelligent system that constantly balances the traction of all four wheels, automatically and seamlessly distributing drive force. The result is stress-free performance and stable handling, with intuitive operation strengthening the sense of connection between driver and machine.

DIRECT4 uses ECU sensors to collect, evaluate and react to a range of factors, including vehicle speed, steering angle, and G forces. From these inputs, it calculates and immediately applies the appropriate drive torque to each e-Axle to maximise grip and traction.

The front/rear torque bias can be adjusted from zero to 100 or 100 to zero in milliseconds – faster than any mechanical system. With better communication between the road and steering wheel (or yoke), DIRECT4 also improves steering response.
