Ellipsoid firewall

As with the S-class (W220) and the CL (C215) flagship coupé, the engineers at Mercedes have also developed a new, standard firewall concept for the C-class (W203) sports coupé which offers the passengers even more safety – the ellipsoid firewall.

The name of this assembly stems from the way it curves towards the front. It consists of six different individual components with different panel thicknesses. The engineers have thus been able to adapt the material to the actual load exerted and have achieved a perfect combination of lightweight design and crash safety.

The ellipsoid firewall is connected to the front side members; it can absorb extremely high loads and can distribute the impact forces evenly over a large area to prevent the force of the impact reaching the passenger compartment.
