This Stirling Engine 1900 Mercedes is a fully operational sportscar (albeit a mini-one) powered by an external combustion Stirling engine.

It’s made in Germany from machine-tooled solid brass, aluminum and stainless steel and uses the thermodynamic principle of a regenerative heat engine, powered by the expansion and compression of air.

It works via an alcohol burner in the rear that heats a cylinder, then a quick flip of its dual brass flywheels sets the engine’s displacement and working pistons into motion up to 1,500 revolutions per minute – driving its two 2″-diameter rubber-bound rear wheels forward.

The body design is a replica of the Mercedes 35 HP from 1900.
