It's both a compression and spark ignition engine, and goes between the two modes depending on load. Best of both worlds between a diesel and gas engine, but using gas and at a cost comparable to a standard gas engine.

Wasn’t Porsche the first to market a variable compression spark ignition gasoline fueled car? Sometime in 1975???

Anything with a turbo is variable compression...
