Mitsubishi UK has unveiled the 403bhp Lancer EVO X FQ-400, which is the fastest roadgoing EVO currently available.

Barely a week after announcing the Evolution X FQ-330 SST, which features the six-speed twin-clutch SST transmission and a horsepower bump over the previous FQ-300, Mitsubishi Cars UK has announced a new flagship for the Evolution X lineup. The £49,999 EVO X FQ-400 will be the fastest roadgoing version of the Evolution lineup.

Performance-flagship status is conferred by the 2.0-liter turbocharged engine under the hood, which is rated at 403bhp and 387 lb-ft of torque. The power boost comes courtesy of racing-spec high-flow fuel injectors, a new turbocharger and intercooler, and a three-inch exhaust. The ECU has been remapped to help keep the FQ-400 docile at commuting speeds. Mitsubishi reports a 3.8-second 0-62mph run, and an electronically limited top speed of 155mph (249 km/h).

Mitsubishi's rally-bred Super-All Wheel Control (S-AWC) gets the power to the road. Active stability control, center differential and yaw control are on hand to constantly monitor and enhance the EVO X FQ-400's handling. The S-AWC system has three driver-selectable modes for a choice of three different road surfaces; tarmac, snow and gravel. The FQ-400 also has a widened track and the suspension is lowered 30mm. Eibach springs and Bilstein shocks are installed. The Alcon brakes are also modified, with floating sealed discs, lightened components and high-performance pads.

The FQ-400 is set apart from the rest of the lineup visually by its lightweight 18-inch nine-spoke wheels and Toyo Proxes R1R tires. Hood vents and a composite front bumper with extra lighting and HID headlamps give the FQ-400 the look of a roadgoing rally car. The side skirts are made of composite materials. The massive exhaust exits at the center of the rear bumper's carbon fiber diffuser. The EVO's trademark roof-mounted "Vortex Generator" and a rear wing that incorporates a gurney strip are also part of the visual package.

Inside, the FQ-400 sports Recaro seats, a carbon fiber shifter and a unique handbrake handle. Standard equipment includes Bluetooth phone connectivity, a 30-gig hard drive for the sound system, DVD satellite navigation and automatic headlamps.

The question of whether the rest of the world will get to experience the explosive performance of the FQ-400 has not yet been answered. We can only hope!
