SMART 453 Series Introduction Into Service Manual page 58

The front axle integral carrier is larger compared to that of
the predecessor model series and, with its extended support
base, not only holds the guide and comfort bearings of the
transverse control arm, but also the steering. It also serves
as the crash element for the third (lower) plane. The compo-
nent is designed on a load-dependent basis.

Rear axle
Like model series 451, model series 453 is equipped with a
De Dion rear axle directly mounted to the bodyshell with late-
ral support from cross struts.
The use of this axle design made it possible to develop a rear
axle with competitive features in spite of the relative lack of
available space due to the rear-mounted engine.
The rear axle carrier taken over from the predecessor model
series was integrated into the bodyshell for weight-optimiza-
tion reasons. The De Dion rear axle of the new smart is thus
mounted directly on the body.
