The '''8A80''' is a 90 degree V8 engine designed by Mitsubishi which entered production in 1999. The engine displaces 4.5 litres and has belt-driven double overhead camshafts with 4 valves per cylinder.

The 8A80 has a bore of 86.00mm and a stroke of 96.80mm. Compression uses a 10.7:1 ratio.

The 8A80 features an aluminum block and aluminum heads (a first for any Mitsubishi vee-engine) and weighs only 230 Kg (including exhaust manifolds and catalytic convertors), just 10 Kg heavier than the [[6G72]] 3.0 litre V6.

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.

The actual power of the engine is limited to 206 kW, due to the Japanese [[Gentlemen's handshake]] power agreement. Torque is rated at 412 Nm.

As part of the [[Global Engine Manufactuing Alliance]] (GEMA), engine components are manufactured by both Mitsubishi and Hyundai and shared between the two companies. 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.

==Hyundai G8AB==
Due to the poor quality of Korean fuel, in 2002 Hyundai revised the cylinder heads to accommodate multi-point port fuel injection which was generally more reliable than the GDI version.
