Ruf RGT

The Ruf RGT is a sports car made by Ruf Automobile of Germany.

First generation (2000–2004)
The first-generation Ruf RGT was introduced in 2000 using an engine and chassis based on the Porsche 996. The original 3.6L version could accelerate from 0-60 mph in 4.6 seconds, with a top speed of 190 mph.

Second generation (2005–2011)
When the Porsche 997 debuted, Ruf bored out the 3.6 L engine to 3.8 L, modified the exhaust and catalytic converters, and replaced the ECU and air filter. The new power output was 445 bhp, reducing the 0-60 mph time from 4.6 to 4.2 seconds (or even 4.1, according to some sources), and increasing top speed by 7 mph to 317 km/h.

Ruf also added a performance suspension system, using Bilstein components, as well as high-performance Brembo disc brakes, measuring 13.8 in in front and 13 in in the rear.

The car's appearance is also changed, using a bodykit that includes a polyurethane front air dam and carbon fibre doors, mirrors, engine lid, and spoiler, all of which reduce the car's weight to 2932 lb. The car is fitted with 19 inch Ruf-designed Superleggera wheels and Michelin Pilot Sport Cup tires. Finally, the RGT is customized with interior trim of the customer's choice, including Recaro seats and the deletion of unnecessary parts to save weight.

RGT-8
In 2010, an updated version of the 997 RGT, was unveiled at the Geneva Motor Show. The car was powered by a completely new, Ruf-designed 4.5-litre V8 engine with a 180° flat-plane crankshaft. The engine is based on the architecture of BMW's S65 V8. It features four valves arranged spherically together with multipoint fuel injection which ensure optimal mixture conditions while the dry sump oil system supplies the necessary lubrication. Ruf made the RGT-8 as light as possible by installing aluminum doors, an aluminum hood, a carbon fibre engine cover, and a carbon fibre rear spoiler. Like the flat-6 versions, the new RGT-8 also includes ceramic brakes, an integrated roll-cage, and 19-inch forged alloy wheels with Michelin Pilot Sport Cup tires.

The cost of the RGT-8 is approximately €200,000, not including the price of the Porsche 991 donor car.
