Before stumbling upon this 1955 Woodill Wildfire here at the Barrett-Jackson festivities in Scottsdale, we weren't even aware that such a car existed. And this is one of the reasons why Barrett-Jackson is such a cool event.
Apparently, an employee of McDonnell Douglass (we'd guess with the last name Woodill...) built an experimental turbine engine originally intended for use in a helicopter. First seen in 1952, this machine is recognized as the world's first production fiberglass-bodied automobile. For what it's worth, the Corvette didn't come until late 1953.
According to the official Barrett-Jackson auction page, the engine puts out 310 horsepower at the crank at a stratospheric 37,500 rpm. This particular machine, built in 1955, was reportedly clocked at 137 miles per hour on a dry lake bed and then sat for 40 years until being restored to its current condition.
