The Mitsubishi 8A8 engine is a range of V8 powerplants produced by Mitsubishi Motors since 1999. The only variant to date is the 8A80, a 4.5 L with double overhead camshafts and gasoline direct injection (GDI) technology. Financial pressures forced the company to discontinue sales of the Proudia and Dignity, the only vehicles in its range to which it was fitted, after only fifteen months.[2]

However, the two vehicles were developed in partnership with the Hyundai Motor Company of South Korea, with whom Mitsubishi has had a longstanding relationship.[3] While Mitsubishi makes the cylinder heads and other GDI-related equipment, Hyundai casts the aluminium block, and other major internal components.[4] Hyundai's version of the Proudia/Dignity, the Equus, proved more successful, and this has been the sole application of the powerplant since 2001. Hyundai replaced the engine with its newly developed Tau V8 in 2008 when the second generation rear wheel drive Equus replaced the first model.[5]
