E46 Models
Rear Bulkheads
The rear bulkheads are redesigned to support the roll-
over protection and seat belts. They are welded to
increase structural rigidity and to secure rear seat, rear
seat belts and the mounting point for the ISO child seat.
Variable Top Storage Compartment
The variable top storage compartment is reinforced to make the top storage compartment
rigid and stronger, not to allow twisting moments when the soft top is in its compartment
or when the compartment is opened to enlarge the storage area.
Tension Strut
Tension struts are integrated into the rear of the
body shell to improve the torsional rigidity by not
allowing body twist in the rear. It also keeps the
rear end of the car intact with the middle floor
pan.
Aluminum Support Plate
An aluminum support plate is incorporated into
the front suspension carrier to achieve a high
degree of rigidity combined with low weight.
All of these design improvements increased the
E46iC torsional rigidity by 50% compared to the
E36iC:
• E36 Convertible Torsional Rigidity 6000Nm/degree
• E46 Convertible Torsional Rigidity 9000 Nm/degree
