2012 Mercedes-Benz SLS AMG Roadster include an aluminum spaceframe body, an AMG 6.3-liter V8 front-mid engine with dry sump lubrication developing a peak output of 563 hp and 479 pound-feet of torque, a seven-speed dual clutch transaxle transmission and a sports suspension with aluminum double wishbones.
The Mercedes-Benz SLS AMG Roadster has the same, muscular engine as the gullwing model. The 6.3-litre V8 with a peak output of 563 hp at 6,800 rpm makes the open-top SLS one of the most powerful sports cars in its segment. Its power-to-weight ratio is 6.5 pounds per hp. This naturally aspirated engine generates its maximum torque of 479 pound-feet at 4,750 rpm. The convertible SLS AMG accelerates from zero to 60 mph in 3.7 seconds (0-100 km/h in 3.8 s), and the top speed is 197 mph / 317 km/h (electronically limited) – which means that the Roadster has almost identical performance to the gullwing.
The high-revving 6.3-liter V8 engine has the typical characteristics of powerful racing engines. It responds immediately and effortlessly to accelerator movements. The use of a dry sump lubrication system allows for a considerably lower installation in the vehicle, yielding a lower center of gravity for high lateral acceleration and thrilling driving dynamics.
