Chrysler Turbine
The Chrysler Turbine was an experimental engine developed by Chrysler in the 1960s. What made this engine unique was that it used a turbine instead of a traditional piston engine. This turbine was powered by burning fuel and spinning a rotor, which then turned a shaft to create power. The Turbine was also designed to run on a variety of fuels including diesel, kerosene, and even vegetable oil (via Car & Driver).

This made it a versatile engine that could operate in different environments and conditions as a result. However, the Chrysler Turbine was not widely adopted due to its high cost and complexity and only a few prototypes were ever produced. Despite this, the Chrysler Turbine remains an interesting and innovative piece of automotive history.
