In 2005, Mitsubishi introduced a concept version of the next-gen Evolution at the 39th Tokyo Motor Show named the Concept-X.
Mitsubishi unveiled a second concept car, the Prototype-X, at the 2007 North American International Auto Show (NAIAS).
Lancer Evolution X will feature a newly designed 4B11T 2.0 L turbocharged, all-aluminum Straight-4 engine. Power and torque depend on the market (U.S.A. version: 295 hp and 300 lbf·ft, Japanese version: 280 hp and 310 lbf·ft, UK version: 276 bhp at 6500 rpm, 311 lbf·ft at 3500 rpm ).
The car has also a new full-time four-wheel drive system named S-AWC (Super All Wheel Control), an advanced version of Mitsubishi’s AWC system used in previous generations.. The S-AWC uses torque vectoring technology to send different amount of torque to any wheel at any given time.
It also features Mitsubishi’s new sequential semi-automatic six speed Twin Clutch SST twin-clutch transmission with steering-mounted magnesium alloy shift paddles. A 5-speed manual gearbox will also be available. Mitsubishi claims that the 5 speed manual transmission has always been preferred in rallying and should be very refined, resulting in a more satisfying drive. New Lancer Evolution will incorporate Mitsubishi’s next generation RISE safety body.
The production version of Prototype-X has begun production in Autumn 2007. The Evolution X went on sale Oct. 1, 2007 in Japan  and will go on sale in January 2008 in the U.S.A. , February in Canada (will be the first version of Evolution in Canada) and in March 2008 in the UK . UK Pricing will be officially announced on December 14th 2007 and the car is expected to range between £30,000 and £40,000. Twin Clutch SST version will be available in Japan in November 2007.
