M cars come with a package of intelligent safety features designed to minimise the risk of accidents. Highly robust, large-volume supporting structures and the use of ultra-high-strength multi-phase steel ensure maximum rigidity in the safety passenger cell, while keeping weight to a minimum.
In the event of a collision, the impact is channelled away from the passenger cell to other parts of the car body, such as the undercarriage, side members, front bulkhead or roof and is absorbed by deformation zones at the front and rear. In a side-on collision, occupants are protected by strengthened structures in the B-pillars and side skirts, highly-rigid side impact protection in the doors, as well as a stable seat crossmember.
To better protect pedestrians, a shock absorber is built into the front area between the bumper and bumper cover, which reduces the severity of leg injuries. In addition, the bonnet is fitted with deformation elements that form a crumple zone and help absorb impact energy.
Optional Dynamic Safety warns the driver if it detects signs of tiredness, safety belts are pretensioned in critical situations, electric seats are returned to upright positions and the windows and sliding roofs are closed. In an emergency, the system is also able to brake the vehicle to a stop.
