1976 Porsche 934
- Engine
- 3.0L flat-six, single turbocharged
Porsche 934 chassis 0172, one of only 31 examples built, was delivered new in 1976 to Hamburg tyre importer and racing driver Richard Leder. After his death that year, the car passed through several competitive German and Swiss owners, accumulating 18 overall or class victories and 29 podiums from 69 starts. Subsequently converted to 935 specification and later restored to original Group 4 configuration with its period parts, the car is regarded by marque expert Andy Prill as probably the finest surviving example of its kind.
