The BTR was powered by a 3.4-litre, flat-6 turbocharged engine, producing 374 PS (275 kW; 369 hp) at 6,000 rpm and 480 N⋅m (354 lbf⋅ft) of torque at 4,800 rpm. It came standard with a five-speed manual transmission, though a six-speed transmission became available in 1988 upon request. Other changes included bigger brakes and a stiffer suspension system.

Changes done to converted customer cars included a Ruf 5-speed manual transmission, quad-pipe exhaust system, Recaro leather seats, Ruf instrument clusters and steering wheel, Simpson race harness, twin-plug conversion applied to the engine, engine capacity increased to 3.4-litres with modifications done to the turbocharger, a front spoiler with an oil cooler, optional Porsche 935 style wing mirrors and Ruf 5-spoke 17-inch alloy wheels. The BTR conversion was available either for the 930 Turbo or for a Carrera 3.2.

Performance[edit]

Test results with narrow 911 body (by Car & Driver):

  • 0–48 km/h (30 mph): 1.6 seconds 
  • 0–97 km/h (60 mph): 4.3 seconds 
  • 0–161 km/h (100 mph): 9.6 seconds 
  • 0–209 km/h (130 mph): 16.9 seconds 
  • 0–241 km/h (150 mph): 24.3 seconds 
  • 1⁄4 mile (402m): 12.5 seconds at 180 km/h (112 mph) 
  • Top speed: 305 km/h (190 mph) (tested by Auto, Motor und Sport)

In 1984, a Ruf BTR won the "World's Fastest Cars" contest held by the American car magazine Road & Track with a 10 mph (16 km/h) lead and also dominated the acceleration tests. It accelerated from 0–97 km/h (0–60 mph) in 4.7 seconds, 0–161 km/h (0–100 mph) in 10.4 seconds, covered 1⁄4 mile (402 m) in 13.3 seconds at a speed of 177 km/h (110 mph) and managed a top speed of 300 km/h (186.2 mph).[5]

At the next contest three years later, the same car, with 211,000 trouble-free miles on the odometer, visited outside the competition and attained a top speed of 301 km/h (187 mph), still able to outperform most of the newer cars including the Lamborghini Countach 5000 QV, the AMG Hammer, the Ferrari 288 GTO, the Ferrari Testarossa and the Isdera Imperator 108i, only the Porsche 959, the Ruf CTR and a Koenig modified Porsche 911 Turbo with engine by RS-Tuning were faster.

In Auto, Motor und Sport 22/1984 issue, a Ruf BTR set a new 0-100 km/h acceleration record for production cars tested by the magazine. It accelerated from 0–100 km/h (0–62 mph) in 4.6 seconds, 0–200 km/h (0–124 mph) in 15.5 seconds and covered a standing kilometre in 23.0 seconds.
