The Ruf BTR (Gruppe B Turbo RUF) is a sportscar built by Ruf Automobile of Germany starting 1983, based on the classic 1978-1989 Porsche 911, available in a narrow 911 or optional in a wide Turbo body configuration (the drag difference causing more than 12.5 mph (20 km/h) difference in top speed). It was powered by a 3.4 liter, flat-6 turbocharged engine, producing 480 N·m (350 lbf·ft) @ 4800 and 374 bhp (279 kW) @ 6000 rpm. It was coupled to a five-speed transmission, a six-speed transmission became available 1988 by request.
The Ruf BTR was the first car with Ruf VIN, construction of each vehicle began at the bare chassis level. About 20-30 were built this way, probably even more were converted from customer cars.
In 1984 a Ruf BTR won the "World's Fastest Cars" contest of the American car magazine Road & Track with a 10 mph (16 km/h) lead and also dominated the acceleration tests. It did 0-60 mph (97 km/h) in 4.7s, 0-100 mph (161 km/h) in 10.4s, 1⁄4 mile (402 m) in 13.3s reaching 110 mph (177 km/h) and managed a top speed of 186.2 mph (300 km/h).[3]
At the next contest three years later the same car, with 211,000 trouble-free miles on the odometer, visited outside the competition and did 187 mph (301 km/h), still able to outperform most of the newer cars including Lamborghini Countach 5000 QV, AMG Hammer, Ferrari 288 GTO, Ferrari Testarossa and Isdera Imperator 108i, only the Porsche 959, a RS-Porsche and the Ruf CTR were faster.

In Auto, Motor und Sport 22/1984 a Ruf BTR set a new 0-100 km/h acceleration record for production cars tested by the magazine. It did 0-100 km/h (62.1 mph) in 4.6 seconds, 0-200 km/h (124.3 mph) in 15.5 seconds and 0-1,000 m (0.62 mi) in 23.0 seconds.[2]
