2005 Ruf RT 12

The discrete town of Pfaffenhausen, Germany is an unsuspecting place to find one of the leading Porsche tuners. However the drive to that area, reveals country roads, winding around the plains of Southern Germany with a view distance to die for. And if these roads prove too congested to test RUF’s newest biturbo Porsche, the unlimited speed Autobahn is just a beat away.

RUF, under the guidance of Alois Ruf (pronounced roof), have been tuning Porsches for nearly three decades. Each car is unique in specification, having customer-specified drivetrain, chassis and body components. In some cases, RUF creates a completely new car, with a proud VIN number designated by the company.

Most of the models found on this page are showcars that have defined the RUF image and exposed the possibilities for potential customers. The first prolific RUF was the CTR ‘Yellow Bird’ which gained lots of media attention with its high speed runs and quick laps time around the Nuremburgring. Their latest showcar is based off the recently facelifted Porsche 911, and is one of the most exciting yet.

Called the RT12, RUF’s newest product provides a combination of high end performance and every day use. Biturbo engines are RUFs specialty, and since 1977, they have proven it is the next evolutionary step for the 911. Three different performance options are available for the RT 12: 530 bhp, 560 bhp and 650 bhp. The 650 bhp 3.8 liter engine is new in construction, one which sets a new benchmark in performance and is fully adjustable by means of a wastegate.

Body modifications for the RT 12 are radical, and aerodynamic efficiency was the goal of the bodykit. RUF-developed front and rear bumpers, a rear spoiler, side mirrors, an underbody lining and wider rear fenders which offer space for the integrated intercoolers. The RT 12 is finished off with the latest evolution of the RUF new alloy wheels in striking 19 and 20 inch designs.

An available brake system has larger drilled, ventilated discs and fixed light alloy monobloc calipers. Also available is a special RUF sports suspension, which can be lifted hydraulically lift for more ground clearance, making easier parking and garage entrances.

The interior of the RT 12 gets the distinct RUF treatment. Bucket seats and a handy sports steering wheel provide the best ergonomics for a sporting drive. RUF instrumentation with traditional green typeface and ‘Pepita’ cloth in the middle of the bucket seats brings the flair of the 50s and 60s sports cars into a modern cockpit. Aluminum parts and details painted in the body colour provide the mix of classic and modern cues.

RUF have proven themselves a logical solution for Tuning Porsches in the past, and now they are the first to work out a program for the facelifted 911. While RUF only modify from 20 to 25 cars a year, the showcars prove RUF have the tenacity to still create some of the fastest road cars in Germany.
