RUF BTR (allerlei)

Ein Anfang

Von 1983 bis 1989 bot Ruf Automobile den BTR an, was eine Abkürzung für «(Group) B Turbo RUF» war. Man geht davon aus, dass Ruf selber etwa 20 bis 30 Exemplare baute – und eine ungezählte Anzahl von Kundenfahrzeugen umbaute, wobei entweder ein 930 Turbo oder ein Carrera 3.2 als Basis diente. Die Modifikationen von Ruf bestanden in erster Linie im BTR-Motor: Dieser wurde auf 3,4 Liter Hubraum vergrössert, der Turbolader modifiziert und eine Doppelzündung eingebaut. Das Ergebnis war eine Maschine mit einer Leistung von 374 PS. Zu den weiteren Modifikationen gehörten das Ruf-eigene Fünfganggetriebe, ein neues Kombiinstrument, verbesserte Recaro-Sitze mit Simpson-Renngurten, ein spezielles Lenkrad, Leichtmetallfelgen in 17 Zoll und ein Frontspoiler mit integriertem Ölkühler. In einem Test von «Car & Drive» wurde behauptet, der Wagen sei in der Lage, in nur 4,3 Sekunden von 0 auf 60 zu beschleunigen, und in einem von «ams» durchgeführten Test wurde eine Höchstgeschwindigkeit von 306 km/h erreicht.

Auktion: RM Sotheby’s, Open Roads 2021, verkauft für 176’000 Dollar, angeboten mit folgendem Text: «Delivered new to Germany, this Porsche began life as a 1981 911 Turbo Coupe. It left the factory finished in Paint to Sample Metallic White (Code 99) with black anodized trim. It was factory-equipped with an electric sunroof, black headliner, a heated and tinted windshield, and Goodyear tires. It is one of 698 Rest of World (ROW) 930 Turbos built for 1981. In 1987 Dr. Wilfried Eckhardt, a well-respected physicist who is believed to have split time between Frankfurt-Sachsenhausen, Germany and Malibu, California, had the car converted by RUF in Germany to a BTR. The car was upgraded to a BTR 3.4-liter single-turbo engine with a new intercooler and RUF’s four-pipe exhaust system. The engine produced a breathtaking 374 bhp. It was mated to a new RUF-built five-speed “dog-leg” transaxle with 40-percent limited-slip. An additional front oil cooler was installed in the redesigned front fascia, which was edged with a new fiberglass spoiler. The interior was not ignored; the RUF invoice notes new instrumentation, including a speedometer calibrated in miles-per-hour, with Dr. Eckhardt having made his intentions clear to export the BTR stateside; and a larger boost gauge replaced the standard clock. The owner also specified a cruise control system and a security system. Soon after this expensive conversion was finished, Dr. Eckhardt arranged shipment to the Port of Los Angeles in the Fall of 1987. Nearly a year after getting the car stateside Dr. Eckhardt had new seats installed and modifications done to the suspension which raised the ride height. Dr. Eckhardt took very good care of the RUF under his ownership, evident in the service invoices on file from 1988 to 1997 with nearly all work carried out by the Porsche specialists at Motorsport Inc. in Los Angeles. The car changed hands at least twice in the early 2000s, remaining in the state of California. The engine was completely rebuilt and a new clutch was installed by Foreign Sport Technician in Santa Monica in 2004 with 43,045 miles. The RUF eventually found its way to Virginia around 2008. At that point and Alpine stereo was installed along with an Infinity speaker. Additionally the suspension was gone through and items requiring replacement were addressed. In 2015 the RUF was acquired by a private collector of sports cars and motorcycles from Michigan. He had the car repainted in 2016. The consignor purchased the RUF from the collector in 2018. Today, this 1981 Porsche RUF retains its desirable BTR engine and RUF gearbox. It rides on a set of RUF Speedline 17-inch forged alloy wheels, sourced by the consignor. They’re shod in Continental Extreme Contact Sport tires and have covered less than 1,500 miles. The seats are trimmed in blue leather with tartan inserts. Further modifications to the interior include an Indianapolis Formel leather wrapped steering wheel and a WEVO shifter with a wood shift knob. The RUF branded odometer displayed 52,108 miles at the time of cataloguing».
