Ruf introduced the model in Autumn 2004 at the Essen Motor Show as the first of their offerings built on Porsche's then new 997 platform. A twin-turbocharged 3.6-litre flat-six engine based on the previous 996 Turbo's engine is rated between Template:Cvt options while the bored-out to Template:Cvt and destroked to Template:Cvt for a total displacement of Template:Convert. The engine is rated at Template:Convert at 7,000 rpm and Template:Convert at 4,000 rpm on "S" trim; or Template:Convert at 7,000 rpm and Template:Convert at 3,500 rpm on "R" trim. Modifications include replacement of the VTG turbochargers with KKK units, a cast alloy intake manifold, gas-flowed cylinder heads, larger throttle bodies, and 102 mm Mahle pistons with custom built camshafts. The turbochargers have a boost of Template:Convert.[1][2] The engine has a redline of 7,500 rpm.
The Rt 12 features specially developed Ruf bodywork, giving the vehicle a unique appearance while functioning to increase downforce, improving high speed stability. Large cross-drilled brakes are included, although some debate has arisen as to how much of an upgrade the system provides over the factory-optional ceramic brakes (PCCB) that Porsche offers on "S" model 997s. Due to doubts over the PCCB system, Ruf chose not to opt them for the Rt12.[3] In addition, Ruf replaced the factory "active" suspension system with a static system of their own design. A system with hydraulic control, developed together with Öhlins, which can raise ride-height in situations such as driveway entries is available as an option. The Rt12 exterior is distinguished from the standard Porsche 997 Turbo by the air tunnels on the rear haunches supplying allegedly cooler air for the twin turbochargers than the lower tunnels in the Porsche.
In total, 13 cars were made. Rear-wheel-drive was available as an option. All but two customers have ordered their Ruf Rt 12 with AWD.Script error: No such module "Unsubst".
Performance

The Rt 12 has a 0-Template:Convert time of 3.8 seconds and a top speed of Template:Convert with standard gearing,[4] very similar to the RUF CTR2's 217 mph record from 1996. This gave it superior straight-line performance when compared to similar sports cars such as the Ferrari Enzo, Porsche Carrera GT, and Mercedes-Benz SLR McLaren. Comparable sports cars include the McLaren MP4-12C (which is faster off the line but has a slightly lower top speed.)[5]
Although the top speed is officially reported as Template:Convert, there is an optional taller gearing package which is reported to boost the car's top speed to Template:Convert.[6][7]
