By 1964 the buying public wanted bigger cars so the F85 and Cutlass models were increased in size. For performance enthusiasts the F85 came with the 4-4-2 options and in 1966 became a model line in itself, which ceased with the end of the muscle car era in the early 1970s. The Cutlass could be bought with the big 455 V8 until the power dropped in 1972. The 1974 car with 275bhp signaled the end of the big cars. This is a book of contemporary road tests, new model introductions, specification and technical data, driver's impressions, long term tests, racing, development and history.
