Mitsubishi in the UK has sold a number of special edition Lancer Evolution models over the past several years under the FQ name. The cars are essentially regular Evos with uprated powertrains and in some cases also feature custom bodykits and interior pieces. In the current lineup, the most powerful FQ car is the FQ-360 model, which as its name suggests develops 360hp (268kW). However, according to a new report Mitsubishi is planning to launch a 400hp (298kW) FQ-400 model.

The car was reportedly given the green light after the success of Mitsubishi’s own Evo X race car in the recent Britcar 24hr race at Silverstone, in which it took first place. The production version will likely be built by Mitsubishi’s motorsports department in association with tuning specialists Rampage, Owen Developments and Flow Race Engines.

Official details are yet to be revealed but the car is expected to generate at least 405hp (302kW) and 400lb-ft (540Nm) of torque from the Evo’s 2.0L turbocharged engine. Some of the planned modifications include an upgraded turbocharger, a new exhaust manifold and a revised ECU and fuel system. The five-speed manual will be the only transmission option due to the unknown reliability of the dual-clutch SST under such heavy loads, reports AutoCar. The new range-topper won't have a race clutch as the FQ-360 did, however, making it considerably easier to drive day-to-day.

Expect to see most of the goodies from the current FQ-360 model make their way onto the new flagship – items such as a custom carbon-fiber front lip, a new rooftop vortex generator, bigger air intakes and unique badging. With 360hp (268kW) on tap, the FQ-360 accelerates from 0-60mph in just 4.1 seconds, and the more powerful FQ-400 model is expected to get down to just 3.5 seconds for the same sprint.

Upgraded brakes, with six-piston calipers up front and 18in alloy wheels will improve handling and stopping power.

The car is also expected to be the most expensive Evo ever, starting at about £45,000, a rise of £14,500 over the previous FQ incarnation. Only 100 are scheduled for the initial production run, though more could come should demand prove strong enough. First deliveries are expected to start early next year.
