SMART 453 Series Introduction Into Service Manual page 106

Front end
The front end largely consists of plastic assembly parts as
well as a bolted flexural member with crashboxes made of ul-
trahigh strength sheet steel (for ease of replacement in event
of repair).
The different crashboxes are matched to the different vehicle
weights:
• Light two-seater
• Heavy two-seater and four-seater
Front end with firewall
The front end structure largely consists of the front longitu-
dinal members with integrated front integral carrier mounts,
the suspension strut supports, the inner A-pillar structure
including second longitudinal member plane and connecting
carriers with integrated rear integral carrier mounts (for two
integral carrier variants). The firewall and a crossmember
which meets pedestrian protection requirements under the
windshield form the boundary to the interior compartment.
In the event of a collision, the loads are distributed through
the front end elements, the A-pillars, the crossmember and
the connecting carrier towards the rocker panels, center tun-
nel, roof structure and doors.
Sidewall
The sidewall of the new smart has a three-piece structure
across almost its entire length. This consists of an inner side-
wall, a reinforcing frame and a one-piece panel.
To provide optimal protection in the event of a collision and
maintain the integrity of the tridion safety cell, the reinforce-
ment frame largely consists of high strength and ultrahigh
strength steels.
