VW Type 4
Volkswagen introduced the Volkswagen Type 4 in 1968, The model 411, and later the model 412, offered many new features to the Volkswagen lineup. The model 411 and 412 were discontinued in 1974 when sales dropped, but the Type 4 engine continued to be used for Volkswagen vehicles produced from 1972 to 1979: it was modified and later used in the Vanagon which was air-cooled from 1980 until mid-1983.
Porsche discontinued the 914/916 variant in 1972 after production of 3,351 units; its place in the lineup was filled by a variant powered by a new 95 metric horsepower (70 kW; 94 bhp) 2.0-litre fuel-injected version of Volkswagen's Type 4 engine in 1973. For 1974, the 1.7-litre engine was replaced by a 76 metric horsepower (56 kW; 75 bhp) 1.8-litre, 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-litre engine continued to be used in the Porsche 912E, which provided an entry-level model until the Porsche 924 was introduced.
