Torque Vectoring
Torque vectoring actively varies drive or braking torque between wheels or axles to influence traction, stability, and how a vehicle turns.
How it can be implemented
The term covers different hardware. A vehicle may use individual motors, an electronically controlled differential or clutch, selective friction braking, or a combination. Multi-motor EVs can change front-to-rear torque and, with suitable drive units, left-to-right torque very quickly.
The control system responds to inputs such as steering angle, accelerator position, wheel speeds, yaw rate, and available grip. Its goal may be stability, agility, traction, efficiency, or a balance chosen by the drive mode.
Not every all-wheel-drive EV provides true left-right drive-torque control, and brake-based intervention is not identical to independently driven wheels. Marketing names should therefore be checked against the actual drivetrain. See Multi-Motor EV Architectures for motor layouts, axle control, disconnect systems, and wheel-level torque distribution.
