The Mitsubishi Lancer Evolution, known as the Evo, is a car manufactured by Mitsubishi Motors. There have been ten versions to date, and the numerical designation of the model is most commonly a roman numeral. All of them share a two liter, turbocharged engine and four-wheel drive system.

The evolution is based on the same platform as the Lancer. However, it is much more powerful than the standard Lancer, with the unibody being the only major part in common between the two.

The Evolution was originally intended only for Japanese markets but demand on the 'grey import' market led the Evolution series to be offered through limited type-approval in the United Kingdom and in various European markets from around 1998. Mitsubishi decided to export the eighth generation Evolution to the United States in 2003 after witnessing the success Subaru had in that market with their Impreza WRX, a direct competitor in other global regions.
