What Happened to the Chevrolet Corvair Turbo Flat-Six?

In the early 1960s, Chevrolet built something America had never seen before.

Hidden in the back of the Corvair was a lightweight, aluminum, air-cooled flat-six — and in its most radical form, it was bolted to a TRW turbocharger, producing up to 180 horsepower from just 164 cubic inches.

It was small, strange, fast, and years ahead of its time.

This engine beat Porsche to the turbocharged passenger car market by more than a decade. It proved that Detroit could build an advanced, power-dense engine with aerospace thinking, aluminum casting, forced induction, and a sound unlike anything else on American roads.

But the American market wanted something simpler.

Drivers trusted big cast-iron V8s. Mechanics understood them. Dealerships knew how to sell them. The Corvair turbo flat-six demanded premium fuel, careful maintenance, respect for heat, and a driver willing to understand the machine.

Then came fear, bad press, falling sales, and a corporate pivot back toward the safe comfort of front-engine V8 power.

This is the story of the Chevrolet Corvair Turbo Flat-Six — the engine that showed America the future, only to be abandoned by the very company that created it.
