After successfully driving its way into the luxury car market, http://infiniti.com/us/” target=”_blank”>Infiniti now looks to also be taken seriously in the performance car arena, perhaps inspired by their success as a Red Bull F1 sponsor. Their first weapon comes in the form of this Q50 Eau Rouge Concept, debuting this week at the http://naias.com/” target=”_blank”>North American International Auto Show (NAIAS) in Detroit and based on the Q50 and with a name garnish inspired by the ballsiest (is that a word?) in the Spa-Francochamps F1 circuit. The release is a clear challenge to the AMG’s and M’s out there, built with plenty of carbon fiber, an arching front end, and wheel arches that encase 21-in forged wheels. We have a few images of the cabin, but what’s lurking under the hood is a mystery right now. All we have is a hint from Infiniti President, who noted that it could feature a 500 hp to 600 lb-ft torque-producing engine. All this talk sounds nice, but we’ll have to wait to see what actually hits the dealerships.
