- Engine
- 3.0L air-cooled flat-six, single turbo, Bosch K-Jetronic fuel injection, 234 bhp
- Colour
- Oak Green Metallic
Chassis 930-0014 is the fourth and final of four pre-production 1975 Porsche 911 Turbo (Type 930) prototypes prepared during summer 1975 for factory photography and testing before retail production began. Finished in Oak Green Metallic with a bespoke tartan-and-leather interior, it was shipped to Volkswagen of America for U.S. homologation work, then passed through a California dealership and several private owners before accumulating just over 111,000 miles. Its significance as a documented pre-production prototype is supported by a Porsche Certificate of Authenticity and period service records.
