E46 Models
Body Shell
The body shell of the E46iC has been developed specifically for the convertible to improve
crash performance which is similar to the E46 Coupe. This was achieved by the use of
reinforcements on the body shell that improved torsional rigidity (body twisting). In the main
body floor pan, reinforcements were necessary to accommodate the new SGS (Seat
Integrated Belt System) seat system. In the rear floor pan, reinforcements were necessary
to account for the variable convertible top storage. compartment floor.
Components
Floor Pan
The floor pan is reinforced to support the SGS seat by heavier cross brace members, rein-
forced tunnel/floor pan and reinforced engine support brackets. During a collision all forces
occurring on the seat are channeled to be absorbed by the floor pan.
Windshield Frame
The windshield frame is reinforced with stepped
reinforcing tubes to allow it to act as a roll-over pro-
tection. During the rollover all of the forces exerted
on the A-pillar of the windshield frame are transmit-
ted as a Moment (Torque) to the bottom of the A-
pillar where stepped reinforced tubes are reinforced.
