1954 Fiat Turbina Concept, Three Turbine Engines, No Waiting

The Fiat Turbina is one of those odd little engineering exercises which eventually fade into the ether. As a car, it certainly was interesting to look at, beautiful even, and wore high fins way before they were cool. But the really slick stuff was under the skin. The mid-mounted powerplant consisted of three different turbines all working together. Two acted as compressors for the third, which in turn powered the wheels. With peak output of 220 HP at a staggerin 22,000 RPM, the Turbina was capable of a very respectable 155 MPH.

Though we all know how successful turbine-powered cars turned out to be, you have to admit this is a pretty novel approach to open chamber combustion. You can visit the Turbina today where it lives in retirement at the Museo Nazionale dell'Automobile in Turin, Italy.
