Named after one of the most challenging turns at Belgium's Spa Francorchamps Circuit, the Q50 Eau Rouge is "infused with the enticing spirit of Formula One." So say Infiniti, who has just revealed the concept at the Detroit Motor Show, offering a glimpse of what to expect of its future high-performance production models. The Japanese carmaker has finally decided to cross swords with BMW M, Mercedes AMG, Audi RS and Cadillac V models, and the Q50-based concept demonstrates what it has in store.

Without specifying what's under the hood, Infiniti president Johan de Nysschen said it would be a "V-cylinder engine with forced induction [and] feature over 500 hp and 600 lb-ft of torque." A heavily revised 3.7-liter twin-turbo V6 from the standard Q50 is the likely candidate. Apart from the front doors and arch of the roof pillars, all other parts of the sports sedan concept's carbon-fiber body have been specifically crafted. New fenders widen the stance, a carbon-fiber roof lowers the center of gravity and improves stability, while other upgrades include 21-inch alloys, a twin-exhaust, carbon-fiber wing mirrors, and a rear brake light borrowed from Red Bull's RB9 F1 car.

The sculpted front wing and rear aerodynamics package are further nods to Formula One, while the cabin boasts a high-grip sports steering wheel and F1-inspired paddle shifters. Red carbon-fiber trim and dark chrome accents complement the restyled seats better than you may expect.
