The body of the BMW 7 Series offers an exceptionally good balance of optimised weight and all-round solidity. The consistent use of aluminium parts has reduced the overall weight of the car by another 22 kilos, 7 of which are due to the replacement of the steel roof. The resulting change
in the centre of gravity makes a significant contribution to the car's agility. This is BMW EfficientDynamics: reduced fuel consumption, increased driving pleasure.
