Porsche introduced the 934 and 935 in 1976 as production-based racing cars derived from the 930 Turbo. The 934 was a Group 4 car, staying relatively close to its road-going counterpart with around 485 hp. The Group 5 935 was a more extreme evolution, featuring wild aerodynamic bodywork, including the iconic "Slantnose," and engines that eventually produced over 800 hp in the final 935/78 "Moby Dick" variant. These cars dominated sports car racing, winning at Le Mans, Daytona, and Sebring and cementing the 911's competition legacy.
Collectors prize these cars for their historic racing significance and brutal performance. With low production numbers, each chassis has a unique story, and cars with significant race wins or famous drivers command the highest values. They represent a golden era of turbocharging and aerodynamic development in sports car racing. The driving experience is famously demanding, rewarding skilled drivers with incredible speed.
The market for genuine 934s and 935s is strong, with top-tier examples trading for seven figures. The wide range in reported sales reflects the vast difference in condition, originality, and provenance. A car with documented Le Mans history is in a different universe from a rebodied club racer or a collection of parts, so thorough research is essential to understand a specific car's value.
Buying Tips
- Provenance is paramount. A complete, documented history of ownership, race entries, and results is the single biggest factor in determining value.
- Scrutinize the chassis and bodywork for originality and period-correct repairs. Many of these cars were crashed and rebuilt during their racing careers, so identifying a factory chassis is critical.
- A full mechanical inspection by a specialist familiar with vintage Porsche race cars is non-negotiable. These are complex, highly-stressed turbocharged engines and gearboxes that are expensive to rebuild.
- Be aware of the many privateer-built cars and tributes. Teams like Kremer Racing and Joest Racing built their own versions (e.g., K3), which have their own distinct history and value compared to factory works cars.
Reported sales prices range from $9,935 to $1,600,000, which highlights the enormous gap between project cars and documented, race-winning examples.
