About a month ago, Mitsubishi’s U.S. chief Don Swearingen said the Lancer Evolution’s time had “come and gone” and that there would be no direct replacement for the car once the 2015 model year is out. The Mitsubishi exec also said that a special edition model would be launched to mark the Evo’s end.

Today, we have the first details on a new Evo concept that may just preview the special edition model hinted by Swearingen. The new concept is called the Lancer Evolution X Final Concept and it’s set to debut next month at the 2015 Tokyo Auto Salon, the Japanese equivalent of tuning shows like the Essen Motor Show in Germany and SEMA here in the U.S.

The concept is based on the fully-featured Evo GSR equipped with a five-speed manual, and comes powered by a version of the familiar 2.0-liter turbo four worked over by top Japanese tuning firm HKS. Thanks to a new turbocharger setup, high-flow intake and exhaust systems, an upgraded intercooler and recalibration of the ECU, peak power registers at 473 horsepower. By comparison, the standard Evo produces just 291 hp.

The concept is also fitted with forged aluminum wheels from RAYS that measure 19 inches across and are wrapped in Yokohama Advan Neovas tires. And the whole thing sits lower than a standard Evo thanks to HKS-tuned adjustable suspension.

Visual tweaks include a matte black finish for the exterior, which is joined by some glossy black accents on the roof and rear spoiler. Inside, contrast red stitching can be found.

We should have more details on the Lancer Evolution X Final Concept—including news of potential production plans—once the 2015 Tokyo Auto Salon gets underway on January 9. In the meantime, additional coverage of the event can be accessed via our dedicated hub.
