Mitsubishi Lancer Evolution X FQ400

In 2005, Mitsubishi introduced a concept version of the next-gen Evolution at the 39th Tokyo Motor Show named the Concept-X, designed by Omer Halilhodžić at the company's European design centre.

Mitsubishi unveiled a second concept car, the Prototype-X, at the 2007 North American International Auto Show

The Lancer Evolution X sedan features a newly designed 4B11T 1,998 cc (2.0 L) turbocharged, all-aluminium alloy GEMA Inline-four engine. Power and torque depend on the market, but all versions will have at least 280 PS (206 kW; 276 hp). (JDM version), the American market version will have slightly more. The UK models were be reworked by Mitsubishi UK, in accordance with previous MR Evolutions bearing the FQ badge. Options for the UK Evolutions were expected to be between 300 hp (224 kW) and 400 hp (298 kW)

Two versions of the car are offered in the U.S. The Lancer Evolution MR, with 6-speed Twin Clutch Sportronic Shift Transmission (TC-SST). The other version is the GSR which has a 5-speed manual transmission system. The car also has 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.[40] The S-AWC uses torque vectoring technology to send different amounts of torque to the rear wheels.

It also features Mitsubishi's new sequential semi-automatic six speed SST twin-clutch transmission with steering-mounted magnesium alloy shift paddles. It has replaced the Tiptronic automatic transmission, hence the SST version replaced the GT-A version (which was used in Evolution VII and Evolution IX Wagon). A five speed manual gearbox will also be available. The new Lancer Evolution will also incorporate Mitsubishi's next generation RISE safety body.

The Evolution X went on sale October 1, 2007 in Japan,[41] January 2008 in the USA,[42] February in Canada (as the first version of Evolution in Canada)[43] and in March 2008 in the UK.[44] The Twin Clutch SST version was available in Japan from November 2007.[45] Europe will follow with sales in May, GSR and MR version included premium Package. The introduction of the 2010 MR-Touring moved the car even further upscale. Leather and a sunroof became standard while revising the rear spoiler to just a lip spoiler. For the police car, the British Police decided to use these Mitsubishi Lancer Evolution Xs as police cars
