To maximise power, and minimise fuel economy, the 8A80 uses [[Gasoline Direct Injection]] technology, where fuel is injected directly into the combustion chamber. This allows for an extremely lean fuel mixture when the engine is under little load. | To maximise power, and minimise fuel economy, the 8A80 uses [[Gasoline Direct Injection]] technology, where fuel is injected directly into the combustion chamber.

Mitsubishi produces the cylinder heads and direct injection equipment while Hyundai produces the cylinder block, pistons and conrods. The engine however, has only been fitted to the Mitsubishi Proudia and Dignity from 1999 until 2001. The Proudia/Dignity's Hyundai Equus sister had the sole use of the engine from 2001 through 2008. In Hyundai vehicles, the engine is coded G8AA and known as the Omega. |
