Terminology


Definition

The definition of a muscle car is subjective and endlessly debated. Muscle cars often have many of the following characteristics: * A large V8 engine in the most powerful configuration offered for a particular model * Rear-wheel drive * Being manufactured in the United States in the 1960s or early 1970s (the specific year range of 1964–1973 is sometimes used) * A relatively lightweight two-door body (though opinions vary as to whether high-performance

By some narrow definitions, muscle cars are an extension of the hot rodding philosophy of taking a small car and putting a large-displacement engine in it, for the purpose of increasing straight-line speed.

The following year, Ford installed the proven 427 "top-oiler" engine in the smaller and lighter Fairlane body, creating the Ford Thunderbolt. The Thunderbolt included several weight-saving measures (including acrylic windows and fibreglass/aluminium body panels and bumpers) and a stock Thunderbolt could cover the quarter-mile in 11.76 seconds. The Thunderbolt was technically road-legal, however, it was considered unsuitable even "for driving to and from the (drag)strip, let alone on the street in everyday use". A total of 111 Thunderbolts were built. The General Motors competitor to the Thunderbolt was the Z-11 option package for the full-size
