He who brakes wins: during deceleration (overrun mode) and braking, the electric motor acts as an alternator and generates a braking torque on the wheels. The electrical energy generated during this process flows back into the battery and increases its charge level.
The optional radar-based recuperative braking system allows exceptionally effective energy recovery and therefore a longer range. The system available for the electric vehicle and plug-in hybrids uses the data from the radar sensors in the COLLISION PREVENTION ASSIST PLUS system to increase recuperation - and therefore deceleration - or reduce it to zero, as required.
There are four recuperation levels available:
D+: gliding mode, no recuperation
D: moderate recuperation
D–: high recuperation
D Auto: recuperation depending on the traffic situation
