The Ruf RGT is a supercar built by Germany's Ruf Automobile based on the 996-type Porsche 911 GT3. An upgraded camshaft, custom-developed exhaust system, a remapped engine management system and a revamped air filter helped lift the power output from the 3.6-liter flat-6 up to 380 HP. Like the 911 GT3, the RGT routed power from the engine to the rear wheels via a 6-speed manual transmission, but customers could opt for an all-wheel-drive system, if so desired. The Ruf RGT was reported to be capable of going from a standstill to 62 mph in a time of 4.6 seconds and boasted a top speed 191 mph.
