The SL63 features the same 525hp 6.3L V8 engine as the production model and accelerates from 0-62mph in the same 4.6 seconds. A newly developed AMG sport exhaust system with larger pipe diameter and new rear silencers allows the high-revving AMG naturally aspirated engine to breathe even more freely.
Other modifications to the car include an uprated cooling system and new heavy-duty composite brakes. The vehicles feature larger coolers for the engine oil, transmission oil, cooling water and power steering. The SL63 safety car is also 220kg lighter than the production model thanks to a number of weight saving measures. These include carbon-fiber panels used for the bonnet, front and rear aprons, front wings and luggage compartment lid. The car’s roof is also fixed, meaning engineers could remove the complex convertible mechanism. The result is a weight reduction of 220 kg, with the Safety Car weighing in at just 1750 kg (with a full tank and without occupants).
