Additional torque is needed for acceleration, particularly for spontaneous overtaking. This is where the electric motor`s best feature comes in: high torque that’s there from the first rev. If the accelerator receives a command for sudden thrust, the electric motor is activated in addition to the BMW TwinPower turbo. This guarantees an immediate increase in torque of up to 160 Nm. The additional power is then carried directly tot the drive wheels via the eight-speed automatic transmission, making the BMW ActiveHybrid 7`s acceleration noticeably more dynamic.
