1971 Porsche 914/6 GT

9140432505racingGermany
Engine
2.0L flat-six, twin-plug ignition, upgraded to 'Carrera 6' spec, 218 bhp

A Porsche 914/6 GT delivered new in March 1971 to Friedrich Graepel of Loningen, prepared to GT specification by the renowned privateer outfit Autohaus Max Moritz for the Deutsche Rallye Meisterschaft. The car contested six DRM events in both 1971 and 1972, achieving multiple class podiums and an outright GT-class victory in the Stuttgart-Strasbourg-Stuttgart Rally. Damaged during 1975 Lyon-Charbonnieres practice, it remained stored in semi-dismantled condition until a meticulous rebuild to original specification — including a Max Moritz Carrera 6-spec engine — was completed by Mittelmotor GmbH in 2017.
