E60 Bodyshell - Basic
Introduction
In recent years all automobile manufacturers have been increasingly
faced with the problem of spiralling weight in today's motor
view of constantly increasing engine performance, both the chassis and
the body must absorb and transmit ever higher forces.
In addition, cars and their interior are generally larger. The reason for
this development is that the vehicle size is based on the 95% man. The
95% man is derived from the average height of the population. This
means only 5% of the population exceed the size of the 95% man.
Furthermore, in the past few fort demands have increased
continuously resulting in ever fort systems either fitted as
standard or available as optional equipment.
All these factors have lead to an increase in vehicle weight.
The objective during the development of the E60 was to stop or even
reverse this trend.
Consequently, the E60 is the first vehicle to feature a mixed aluminium-
steel construction. The front end of the vehicle is made of aluminium
with a steel passenger cell and rear end.
Thanks to this mixed construction and the use of high strength steels,
the body weight was reduced to 255 kg (not including doors, ,
boot lid and flaps) while weight
