Absolutely stunning and rare Turbo cabriolet that was imported officially by the RUF distributor at the time in 1990 as a new RUF VIN number car. We have the certificate of origin and the car was owned by a collector in eastern Canada for many years. The car then moved to Vancouver and has been in the possession of another collector who never drove it. Its now available for the 3rd owner to enjoy or to view. There is un-verified information that may suggest this is one of one in the world in this combination. The price of the car when new was $249,000 Canadian.
Over the last few years, RUF VIN numbered cars have become sought after and as this generation Porsche has already reached cult status, this one maybe the grand daddy of super cool and super rare!
Be prepared..this rear wheel drive 425 bhp RUF sports cars will awaken your senses quickly.
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 components into the road 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. The RUF BTR was inspired by the Group B Porsche but it was a road car, and built to customer specifications. The car could be ordered with flared Turbo bodywork, or the standard 911 sheet metal which was lower in drag and gave a 20km/hr increase in top speed. The BTR could be built up from a Porsche body-in-white and given a RUF VIN, or a customer car could be modified. It is thought, though not documented, that there are approximately 200 BTR Ruf motors built, but only a couple dozen or so were used in genuine RUF VIN Cars. There were several body styles (narrow or wide body, slant nose, coupe or Cabriolet) and some component differences, though they shared the 3.4 L engine and 6 speed transmission.
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 3.4 L from the original 3.3 L. 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. The first BTR engines used Bosch K Jetronic (CIS), but later engines called BTR III, used Bosch Motronic, and had 408hp up from the 374hp of the CIS engines. The Ruf Motronic system was the first digital engine management system to be available on a street Porsche 911 Turbo and had a dual injectors per cylinder, custom injector blocks and fuel rails derived from the 962 race car. Motronic was a $10,000 option on a BTR, but standard on the CTR. A larger oil cooler was installed in a RUF front spoiler, moving it from the inside passenger fender. RUF single piece forged rims sized 9×17 and 10×17 ran on Dunlop Denloc tires. RUF offered a complete set of gauges including a 350km/hr speedometer, 1.5bar boost gauge, and Tachometer with the red line turned to near vertical.
In the late 80’s RUF modified Porsche G50 transmissions to take the increased demands of the BTR’s prodigious torque. 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.
For the original BTR, power increased from 300hp to 374hp at .825 bar of boost and 425hp with 1 bar. Top speed was 300km/hr for the narrow body car and 280km/hr for the Turbo body. Acceleration to 60mph was in less than 5 seconds; by reaching 62mph in 4.6 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!
Weissach was the North American representative for the RUF company from 2001-2006. So we know lots about the RUF company.
With a Fresh Full maintenance service by the Weissach Porsche Enthusiasts, this collectors Cabriolet is ready for a new home.
