December 18, 2006 Mitsubishi will unveil the Prototype X concept for a next-generation high-performance 4WD sport sedan at the 2007 North American International Auto Show (Detroit Motor Show) on January 7. The Prototype-X concept is an advance development model for the new Lancer Evolution due to be launched in 2007. Prototype-X features styling based on the current Lancer but was developed to project a visibly higher performance image. The concept model is fitted with Mitsubishi's S-AWC*1 (Super All-Wheel Control) vehicle dynamics system and handling control together with a new turbocharged MIVEC2 engine with an aluminium cylinder block and a 6-speed manual transmission.
