Two rear - mounted electric motors transfer both positive and negative torque directly to the rear wheels. (hybridcars.com)
In addition to providing power, they can also apply negative torque vectoring through regenerative braking. (kbb.com)
The Twin Motor Unit dynamically distributes electric - motor torque between the left and right rear wheels, providing both positive and negative torque vectoring (negative, through regenerative braking) to aid performance and handling. (netcarshow.com)
