According to poster jmk2888 at the EvolutionM.net forums, the car you see here is indeed the 2009 Mitsubishi Lancer Ralliart. The poster, who indicates that he works for Mitsubishi in California, says that the car was in the lot briefly but is now "on the way to an auto show." Funny, we happen to be going to an auto show next week, so let's assume the Lancer Ralliart's on its way to Detroit for its official unveiling.
According to the jmk2888, here are the pertinent stats. To be safe, treat everything as speculation for now until we get official info from Mitsubishi:
* 230 - 240 turbocharged horsepower
* 5-speed manual gearbox or Twin Clutch SST available
* Recaro front seats
* Gunmetal-finish Lancer GTS wheels
* GTS rear wing
* Nav system available
In front, the Ralliart gets a unique fascia dominated by a large (but not Evo X-large), chrome-rimmed grille opening. At the top right section of the grille itself, you can see the telltale Ralliart badge. According to the poster, the car in the photo is painted in the orangey-red "Sunset Pearlescent" finish that's currently available on the Eclipse. He also states that there's Ralliart branding on the rear of the car, and some other posters have noted that this car appears to be equipped with the same HID headlamps as the Evo X. Assuming it's going to be in Detroit, expect complete details and many photos of Mitsu's new Subaru WRX competitor early next week.
