The Ruf BTR (Gruppe B Turbo RUF) is a sports car built by German automobile manufacturer Ruf Automobile. The BTR began production in 1983 and was based on the Porsche 911 (produced from 1978–1989) available in a narrow 911 or optional wide body configuration akin to the 930 Turbo (the drag difference causing more than 12.5 mph (20 km/h) difference in top speed). The BTR was the first Ruf production sports car with a company specific VIN.
Construction of each vehicle began at the bare chassis level. About 20–30 cars were built this way, probably even more were converted from customer cars, though no clear records exist to signify the total number of cars produced.
