Porsche
914/6 GT (factory competition)

Why it matters

The 914/6 GT was Porsche's competition version of the mid-engined 914/6, built in small numbers from 1970 for the works and for privateers. A customer-entered car won the 2.0-litre GT class and finished sixth overall at the 1970 Le Mans 24 Hours, and Porsche's racing department also built a dozen special works cars for rallies and endurance events.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Bonhams says the racing department built 12 works 914/6 GTs in 1969 and 1970: three prototype or test cars, two Targa Florio practice cars, three Marathon de la Route cars, three Monte Carlo Rally cars and one RAC Rally car. The three 1971 Monte Carlo cars were driven by Ove Andersson, Bjorn Waldegaard and Gerard Larrousse. Gooding likewise counts as few as 12 works cars, one carrying the internal project code 914/43. A 914/6 GT of model year 1972 also served as the ONS track safety car, which Porsche calls the first safety car in the world with a modern fire-extinguishing system.

For privateers, RM Sotheby's says Porsche's Werk 1 produced 16 customer cars in 1970, and a GT conversion kit was also available through dealers (Bonhams). Bonhams states that of the 12 works cars two were scrapped and the first lacked the full race package, leaving nine, of which seven survive.

Identification guide

How to tell an original from a replica or later conversion.

Per RM Sotheby's, a 914/6 GT has modified 911 S brakes, extra chassis reinforcement, steel fender flares, an additional front oil cooler, wider wheels, a lightweight interior, a plexiglass rear window and several fibreglass body panels. The engine is the 2.0-litre twin-plug 901/25 flat-six (type 'Carrera 6'). Works cars carry internal factory numbers: Bonhams reports a label '914-55' in the door shut of the car it sold, and notes that the factory record card described several works cars as 'Versuch' (experimental).
