Mercedes-Benz SL63 AMG Safety Car and C63 AMG Wagon Medical Car

The SL63 AMG, with its 518-hp, 6.2-liter V-8, may be one of the sportiest AMG models to date—but there’s apparently room for improvement, which Bernd Mayländer will experience at the helm of this modified SL63 Formula 1 safety car this season.
The surgeons at the AMG performance studio managed to cut a whopping 485 pounds from the stock SL63 AMG; the weight drops from 4400 pounds to just over 3900. Take note that this is almost exactly what the SLR McLaren weighs, with its super-costly carbon-fiber monocoque.
How was the feat achieved? The safety car's front and rear skirts, spoilers, and hood are made of carbon-fiber-reinforced plastic, and the power-folding metal top is gone in favor of a lightweight fixed unit. Say goodbye to extensive sound absorption and fancy telematics. AMG's "selective omission" also includes deleting the active suspension-control system (called “active body control,” or ABC).
There are further changes: A louder exhaust system and four-point seatbelts emphasize the sporting aspirations of this safety car, as does the front bumper with larger air intakes and without fog lights. The rear diffuser is altered for better rear-axle cooling.
Now don't get too jealous of Bernd Mayländer. Rumor has it that you will be able to get most of the safety car's improvements in an upcoming SL63 Black Series edition of the SL. Start saving now.
Rather less extensive are the changes to the hot C63 AMG wagon that in modified version is the Formula 1 medical car in 2008. Europeans get the C63 wagon option at a $4020 premium over the sedan. The Formula 1 medical car gets a modified interior, larger exhaust pipes, and a front end without the somewhat tacky fog lights of the standard
