The intelligent safety system in the BMW M3 Sedan.

Sports-style driving requires exceptional safety. Of central importance in the BMW M3 Sedan's comprehensive protection package: driver, front passenger, side and head airbags. All airbags are controlled by the perfectly calibrated safety electronics system - this intelligent coordinator ensures that each bag is inflated to the correct degree to minimise the effects of an impact. The same system can also activate the seatbelt tensioners, deactivate the central locking or cut the fuel pump's activity.
