The Ruf R Kompressor is a sports car introduced in 2006 and built by Ruf Automobile of Germany. Like certain other Ruf models, The R Kompressor was offered both as a complete ground-up car with a unique Ruf VIN or as conversion for an existing 997 retaining the original Porsche VIN.

Specifications

The R Kompressor is based on the Porsche 997 and is offered as a coupe or cabriolet as well, with a choice of rear-wheel drive or all-wheel drive and with a choice of a 3.6 or 3.8 liter flat-6 engine.^[1] All models come standard with a 6-speed manual transmission but a 5-speed RUFtronic automatic transmission with paddle shift was also offered as an option. Both the 3.6 and 3.8 engines have been upgraded with a centrifugal type (supercharger) and an intercooler for each cylinder row, as well as a new intake and exhaust system.

Road & Track measured a 0-60 mph (0-97 km/h) time of 4.0 seconds for the 3.8.^[3] On the exterior, changes to the original 997 design include wider fenders, a restyled front air dam, new rear wing, side mirrors and the signature Ruf designed wheels measuring 19 x 8.5 inches in the front and 19 x 11 inches in the rear.^[4] Additionally, to save weight, the engine hood and spoiler are made of both Kevlar and carbon fiber.
