The vehicle features an 89% aluminum bodyshell, which, at 560 pounds (254kg) makes the car over 40% lighter than a comparable standard frame.

Structural components are optimized for specific tasks, many sheet metal parts are designed to enable the use of 100% recycled aluminum in their construction.

Aluminum and steel-based door hinges are friction-based, permitting doors to remain securely open at any angle.

Corrosion protection has been upgraded as well making it perfect for those who live near the coast (your correspondent has lived near the beach and the effects were not pretty on her motor).

High-quality zinc-nickel coatings or special electrochemical insulation measures have been used to prevent contact corrosion with aluminium.

The new SL Roadster will premiere Magic Vision Control adaptive windscreen wipe/wash system which keeps the windscreen clear by delivering water directly to the wiper blade – yet the driver won’t see a water jet or a film of water over the screen.
