The Eau Rouge was originally revealed at the Detroit Auto Show in January but, at that time, Nissan's luxury wasn't discussing what was under the hood. That part got revealed in Geneva. It's powered by a 560-horsepower twin-turbocharged V6 engine borrowed from the Nissan GT-R. (It's tuned to produce more power in this car.) The Eau Rouge also has the GT-R's all-wheel-drive system. For now, at least, this is just a concept car. No plans for production have been announced.
