Infiniti has released details and video of the company's new 560 hp Q50 Eau Rouge high-performance vehicle ahead of the Beijing Auto Show. Announced at the NAIAS (Detroit) Auto Show in January, the Eau Rouge promised at the time to be a competitor to the Audi, BMW M, and Mercedes AMG gentleman's performance car offerings.

Now the news that the car will use the twin-turbocharged 3.8-liter V-6 from the Nissan GT-R, plus video of F1 Champ Sebastian Vettel testing the prototype leave little doubt as to its nature. The Eau Rouge is a brute.

The GT-R engine delivers 560 hp and 443 pound-feet of torque - sufficient to put it right in the middle of the German high performance sedan brigade.

Infiniti has announced that video of the new luxury sports sedan being put through its paces will be shown on press day at the 2014 Beijing Auto Show (April 20, 2014) and that prototype testing and evaluation is ongoing.

Four time Formula One world champion and Infiniti's Director of Performance, Sebastian Vettel, can be seen testing the Eau Rouge at the Millbrook (U.K.) Proving Ground in the video at the foot of this article and the luxury sports sedan clearly demonstrates elite-level performance and handling.

Not surprisingly, the name "Eau Rouge" comes from one of the most famous sets of corners on one of the most famous circuits on the Formula One Grand Prix calendar - the iconic series of up-hill sweepers on the Belgian Spa Francorchamps circuit. The corners are synonymous with precision high-speed roadholding.

From the liberal use of carbon-fiber on the Eau Rouge to the prominent sponsorship of the Red Bull Formula One team, Infiniti is leveraging its sporting associations to the maximum to emphasize racing credibility.
