Compared to the Mercedes SL65 AMG coupe-cabriolet, the C25 Royale is 180 kilograms lighter, thanks to the extensive use of carbon fiber, which is found on the hood and the fixed roof. This contributes to a lower center of gravity, in addition to the revision of the weight distribution, both aimed at offering improved handling.
Other weight-saving measures include the fitting of a full ceramic brake system, which is 50 percent lighter than on the SL 65 AMG. The German sports car also features a C-Tronic Suspension system developed by Carlsson, which detects road conditions and driving style and acts accordingly. For instance, on bad roads, the car is raised to offer better ride comfort.
At the heart of the C25 Royale is the biturbo V12-engine, tuned to deliver 753 horsepower and 1,320 Nm of torque (973 lb-ft), which is electronically limited to 1,150 Nm (848 lb-ft). These impressive figures allow the C25 Royale to go from 0 to 100 km/h in 3,7 seconds and reach a top speed of 352 km/h (219 mph).
The custom exterior styling is matched to a bespoke interior with Carlsson offering buyers a variety of choices in features and materials.
