Brake Force Display

Brake Force Display





In order to improve the reaction of other drivers to an emergency stop, the (E85) Z4 has a Brake Force Display system. Its purpose is to reduce the likelihood of being driven into by the vehicle behind. The Brake Force Display function will only be available on the US version at series launch. If a deceleration of more than 5m/s2 or an ABS signal is detected, the bulbs in compartment 3 are activated by the light switch centre. They too then receive the full 21 Watts of power. In this way, the brake light plus Brake Force Display function is performed.
