GM Firebird Concepts
Although they introduced the first Pontiac Firebird in 1967, General Motors already used the name on four popular concept cars in the late ’50s. They called them the GM Firebird I to IV, and they were purely show cars with rocket inspired styling, big fins and advanced equipment. The first Firebird had a jet engine, so it was basically an airplane on wheels.
Later, the cars were a bit more conventional but still crazy. They marketed all Firebird concepts as cars of the future with numerous insane features. Some even had a TV on the dashboard and outboard drum brakes. Many car historians claim those concepts were fantasy cars they never intended for production. They only served as attention getters for the car show crowds.
