Chapel Ruf introduced the Rt 12 in the Autumn of 2004 at the Essen Motor Show and based on Porsche's then-new 997 platform. The 3.8-liter twin-turbocharged flat-six engine is based on an earlier 'M96' blueprint and paired with a RUF-built transaxle and limited-slip rear differential. The car's chassis uses a proprietary and fully adjustable RUF hydraulic suspension system (with front axle lift function), and a set of eight-piston (front) and four-piston (rear) calipers reside within a staggered set of three-piece OZ Superleggera wheels. The enhanced mechanical system is further complemented by lightweight carbon fiber components that include the bumpers, rear decklid, and hood. The special Ruf bodywork increased downforce and improved high-speed stability.
When clients selected the optional 'tall' gearing package, the Rt12 could reportedly reach a top speed in excess of 224 miles per hour. With standard gearing, zero-to-sixty mph was accomplished in 3.8 seconds and top speed was reached at 219 mph (352 km/h). Most customers selected the AWD configuration while approximately two selected rear-wheel-drive.
The bespoke Rt12 was built to clients' needs and wishes and it is believed that fewer than fifteen examples were completed by RUT in total during the model's five-year availability.
