The General Motors Firebird II, a gas-turbine powered engineering concept car, was introduced at the 1956 GM Motorama. Firebird II was the successor to the famous 1953 Firebird I.

The four-passenger Firebird II was characterized by innovations like a titanium body, a regenerative gas turbine, all-wheel independent suspension with automatic load-leveling, power disc brakes, alternator, magnetic ignition key, electric gear selection, and individually-controlled air conditioning.
