About RUF Porsches


In the mid-1980’s Ruf Porsches were the fastest cars that money could buy. In the Road and Track “Top Speed Tests” the Ruf Porsches not only had the highest top speed, but also a perfect reliability record. A Ruf BTR achieved 186mph in 2004, and the CTR “Yellowbird” hit 211 mph in 1987. The CTR also held the Nurburgring lap record for production cars at 8min 5 seconds.The letters ‘BTR’ come from ‘Group B’, ‘Turbo’, and ‘Ruf’. In the 80’s Porsche had an extensive racing program, dominating many series including Le Mans, IMSA etc. Porsche didn’t produce any track versions of their cars until the 959 supercar of the late 80’s, and this left the door open to RUF to incorporate race-proven componentry into the road cars. Today Porsche fills this void with their GT2 and GT3 cars. In the early 80’s the FIA had Group 4 (Modified Touring) class and Group 5 (Touring Prototypes). Porsche ran their 934 and 935 race cars in the respective classes. ‘Group B’ was a series started in 1982 and run for 4 years, that created some of the most fearsome (and dangerous) race cars of all time, including the Ferrari F40, Ford RS200, Audi Quattro S1 etc. Group B required a homolgation of 200 road cars.The Basics of the RUF BTR start with the engine, which had the original partially finned cylinder barrels replaced by ones with air-cooling fins around their complete diameter. The bore was increased giving a new displacement of 3.4L from the original 3.3L. Ruf added unique Mahle Pistons and connecting rods and 935 type camshafts. The turbo was replaced by a larger KKK K27 unit, and a larger free flowing intercooler was added. The intake manifold was replaced, as was the exhaust. A larger oil cooler was installed in a RUF front spoiler, moving it from the inside passenger fender. RUF single piece forged rims sized 9x17 and 10x17 ran on Dunlop Denloc tires.


RUF modified the standard Porsche 930 4 speed by adding a 5th gear with the help of Getrag-the top two ratios remained unchanged, and the lower 3 ratios were spread to cover the speed ranges formerly served by 2 gears. RUF also improved the shift linkage that was both lighter and more positive than the stock unit. The cars were lowered and the suspension was stiffened. RUF added an adjustable boost control in the cockpit, changed the steering wheel to a RUF item, and added a RUF tachometer and boost gauge.


Power increased from 300hp to 374hp. Top speed was 300km/hr for the narrow body car and 280km/hr for the Turbo body. Accelleration to 60mph was in less than 5 seconds; by reaching 62mph in 4.6 seconds and 100mph inless then 10 seconds a 3.4 Liter Turbo-Ruf became the fastest accelerating production car ever tested by Auto Motor und Sport. It reached 100mph in only 9.5 seconds. RUF had matched, or even bettered, the performance figures for Porsche’s own Group B Le Mans car!


Starting in 1987 Ruf also made a “CTR” version of the 911, which was inspired by Group C racers, the Porsche 962 being the dominant machine. The CTR used a twin-turbo version of the 3.4L engine, with Bosch Motronic management from the 962. Power was up to 469hp, with 0-60mph in 4.0 sec, and a top speed of 211mph (340km/hr). This was the famous “Yellowbird” that graced the cover of the July 1987 Road & Track, and was declared the ‘Fastest Car In The World’. The CTR’s had special aerodynamic bodies constructed with the drip-rails ground off, the rear wiper removed, an aero mirror etc. The car was also significantly lightened with aluminium door skins and trunk lid-it weighed in at less than 2,600lbs. In 1987 the prices quoted in Road and Track were approx. $150,000 for the BTR Slantnose Cabriolet, and $142,000 for the narrow body CTR Coupe.


RUF made only about 30 genuine CTR’s with RUF Vins, and perhaps the same number of BTR’s. These RUF VIN cars are valuable collector cars today. RUF also modified, to varying degrees, a few hundred customer cars per year, and these account for nearly all of the “RUF” car on the market.
