The Mitsubishi Lancer Evolution, colloquially known as the Lancer Evo or Evo, is a high-performance sedan manufactured by Mitsubishi Motors. There have been ten official versions to date, and the designation of each model is most commonly a roman numeral. All use two litre, turbocharged engines and four-wheel drive systems. The Evolution was originally intended only for Japanese markets, but demand on the "grey import" market led the Evolution series to be offered through Ralliart dealer networks in the United Kingdom and in various European markets from around 1998.
