Design evolution
Volkswagen versions originally came with an 80 hp (60 kW) fuel-injected 1.7 L flat-4 engine based on the Volkswagen air cooled engine. Porsche's 914/6 variant came with a carbureted 110 hp (82 kW) 2.0 L flat-6 engine, taken from the 1969 911T. The engine was placed amidships, in front of a version of the 1969 911's "901" gearbox set up for mid-engine operation. Karmann manufactured the rolling chassis at their own plant, then either sent them to Porsche for fitment of the Porsche suspension and flat-six engine or kept them in house for Volkswagen hardware. 914/6 models used a similar suspension and brakes to the 911, giving the car handling and braking superiority over the 4-cylinder Volkswagen models in addition to higher power output. A Volkswagen-Porsche joint venture, Volkswagen of America, handled export to the U.S., where both versions were badged and sold as Porsches. In Europe, the four-cylinder cars were sold as Volkswagen-Porsches, at Volkswagen dealerships. This "tainted" the car in the opinion of many automotive critics of that era, and a little of that attitude persists to this day.
Slow sales and rising costs prompted Porsche to discontinue the 914/6 variant in 1972 after producing 3,351 of them; its place in the lineup was filled by a variant powered by a new 95 hp (71 kW) 2.0 L, fuel-injected version of Volkswagen's Type 4 engine in 1973. For 1974, the 1.7 L engine was replaced by a 76 hp (57 kW) 1.8 L, and the new Bosch L-Jetronic fuel injection system was added to American units to help with emissions control. 914 production ended in 1976. The 2.0 L flat-4 engine continued to be used in the 912E, which provided an entry-level model until the 924 was introduced.
The 914 was Motor Trend's Import Car of the Year for 1970[2] and a 914/6 piloted by Frenchmen Claude Ballot-Lena and Guy Chasseuil won the GTS class and finished sixth overall at the 1970 24 Hours of Le Mans[3].
