GM recycled some of its dream/concept vehicles in the late 1960s. Such is the case with the Pontiac Cirrus shown at the 1969 Chicago Auto Show. It was redone from the experimental GM-X which was built for the 1964 New York World’s Fair. The exaggerated fastback picked up a new nose and was said to have a Pontiac 400 cubic inch V-8 engine. Inside it was still like an aircraft cockpit with 21 dials and numerous control levers. Pontiac did nothing more with the Cirrus name, which eventually ended up on a line of Dodges in the 1990s. .
