6 Series 645Ci (N62) Coupe
from the passenger side.
The dashboard is basically the same as that on the 5-series. Instead of the fuel-consumption gauge in the
revolution counter, the E63 and E64 have a gauge that shows engine-oil temperature. The interior armrest is
harmoniously integrated into the door panel and thanks to its width and ergonomic styling allows a comfortable
and relaxed seating position.

Front end
GRAV is an acronym of "gewichtsreduzierter Aluminiumvorderbau" and this lightweight aluminium front end
enhances the lightweight design of the car. Almost the entire front end is made of aluminium. The transition to
steel in the composite construction starts in the vicinity of the engine bulkhead.
The reduced weight of the front end contributes much to the ideal axle-load distribution of 50:50. by opting for an
aluminium front end, the designers had to consider the electromagnetic compatibility (EMC) of the material. An
aluminium body gives less effective screening against external electrical radiation. This means that separate
screening is needed for wiring harnesses and control units. Moreover, an earth connection must be provided for
riveted or glued aluminium components. For reasons of safety, individual components are therefore joined with
welded seams in production. If a repair is needed, the function of the welded seams must be replaced by self-
tapping screws.
