The Vauxhall Slant-4 (or Slant Four) is an inline four-cylinder petrol car engine manufactured by Vauxhall Motors. Unveiled in 1966, it was one of the first production overhead camshaft designs to use a timing belt to drive the camshaft. The Slant-4 block was used as a development mule for the Lotus 900 series of engines. Vauxhall used the engine in a variety of models until production ended in 1983.
