Its a 1955 Woodhill Wildfire powered by a gas turbine helicopter engine.
Exactly.
And here's the spiel about it when it was auctioned by Barrett-Jackson:
QUOTE
The Woodill Wildfire is acknowledged to be the world's first production fiberglass bodied car starting in 1952. This experimental idea was conceived and constructed by an employee of McDonald Douglas, Missile and Space Division using gas turbine helicopter engine. The engine develops 310hp shaft output at 37,500rpm. This turbo car was clocked for speed on a California dry lake bed course at 137mph with more potential speed possible by altering the gear ratio. In storage over 40 years and recently restored. Recently serviced by a licensed helicopter mechanic. Runs and drives with special instructions.
