The so-called Turbo RSR is a Group 4 race car developed in the mid-to-late 1970s based on the Porsche 911 Carrera RSR 3.0 and Porsche 930 Turbo. The goal was to create a powerful yet relatively production-based competition vehicle for customer teams. The 934 was first used in 1976 and served as a bridge between production-based race cars and the even more extreme Group 5 vehicles. The Porsche 934 is powered by an air-cooled 3.0-liter turbocharged six-cylinder boxer engine. The engine is based on the RSR unit but was designed to be significantly more powerful with an exhaust gas turbocharger, delivering an output of around 485 hp. Power is transmitted via a four-speed manual transmission specially tuned for racing. The vehicle features a classic rear-engine layout and rear-wheel drive. The 934 was extensively modified for use in motorsports. Independent suspension, reinforced stabilizer bars, special shock absorbers, and a mechanical limited-slip differential ensure high driving stability and traction. The braking system consists of high-performance disc brakes that meet the demands of racing.
The body of the Porsche 934 is based on the 911 but has been specifically widened and aerodynamically modified. Widened wheel arches with appropriately wide racing tires, a front spoiler, and a rear wing improve downforce and driving stability at high speeds. At the same time, the basic shape of the classic 911 is retained, making the 934 visually distinctive. The interior is consistently geared toward racing. A bucket seat, safety belts, roll cage, and minimalist equipment underscore the vehicle’s functional character. Comfort features play no role; instead, the focus is on maximum driver control. Historically, the Porsche 934 was developed specifically for customer racing programs and was extremely successful in competition. It held its own in numerous national and international racing series and was particularly competitive in 1976. Overall, only a relatively small number of vehicles were produced, making the 934 a rare and coveted collector’s item today. The Porsche 934 is now regarded as a major milestone in the turbo era of motorsports. It combines classic 911 technology with innovative turbocharging and impressively demonstrates the transition from production-based race cars to increasingly specialized racing machines.
About the vehicle offered here
According to documentation, Chassis 0159 was first delivered from the factory to its German first owner in March 1976. The owner entered the car in various races across Europe under the TEBERNUM racing team. This included the Six Hours of Monza, where Klaus Ludwig, among others, took the wheel. A year later, the car was sold to the Netherlands, where the winning racing streak continued. Another year later, in 1978, the vehicle was sold within the Netherlands and modified with a 935 body kit. In this bodywork, the vehicle competed in further races. Around 1980, it was sold to a collector, where the Porsche remained for two decades. During this time, he had the race car restored to its original 934 configuration. Subsequently, the vehicle was given the livery of the TEBERNUM racing team, which it had already worn during the 1976 season. In 2003, a Monaco-based Porsche collector finally purchased the Turbo RSR. In December 2005, Porsche issued a certificate of origin for Chassis 0159. The collector had a valuation report prepared in 2018, which is available. The decision to enter the vehicle in historic motorsport became a reality in 2023 following the issuance of the FIA Historic Technical Passport. In the same year, he entered the 934 in races of the Peter Auto racing series. Mechatronik recently acquired the vehicle, bringing the 934 into our inventory. This victorious Porsche 934 offers collectors and enthusiasts a rare opportunity to add the dawn of the Turbo era to their own fleet.
