Technical Data: Trunk

The trunk of the M5 is redesigned due to the exhaust system of the vehicle. The rear mufflers prevent the inclusion of a spare tire well so the M5 will be fitted with the "M" mobility system.

The center of the trunk floor is constructed from a plastic insert that houses the battery and the "M" mobility tank. The battery box incorporates a break - away housing that will cause the battery to move forward in the event of a rear end collision.
