Infiniti Q50 Eau Rouge Concept bows again, now with more GT-R [w/video]

Think back to the 2014 Detroit Auto Show and you'll remember the Infiniti Q50 Eau Rouge concept - a sedan that showed the potential design direction for a seriously high-performance take on the Japanese automaker's new entry-level luxury sedan. And while the show car we saw in Detroit was all well and good, it lacked something. Specifically, an engine. Kind of an important thing for a performance concept, right?
Here in Geneva, Infiniti rolled out that same Q50 Eau Rouge, but with one major modification: the sedan now boasts a twin-turbocharged 3.8-liter V6 under its hood - the same engine that's found in the Nissan GT-R supercar. In the Eau Rouge, this V6 is tuned to produce 560 horsepower and 443 pound-feet of torque, sent to the ground via the GT-R's all-wheel-drive system. Of course, this super-hot Q50 is still purely a concept, but Infiniti says that the potent engine underhood will allow the sedan to sprint to 60 miles per hour in less than four seconds, on its way to a top speed of over 180 mph.
The oft-fabled "four-door GT-R" still isn't confirmed for production, so for now, all we can do is cross our fingers (and toes). Check out the Q50 and its new beating heart in the gallery, above, and scroll below to hear what that potent Eau Rouge sounds like.

Race Recap: 2013 Bahrain Grand Prix follows the template of this year and last [spoilers]

The sand, the wind, the penalties, the contact and the one crash - all of them collided to make the Bahrain Formula One Grand Prix a surprise affair from day to day and lap to lap. Oh, and did we mention the tires? Pirelli made a last-minute swap after the amusement park ride that the Chinese Grand Prix turned into with the soft compound tire, and brought medium and hard compounds to the desert. That didn't stop things from falling apart for some teams - literally - and that didn't stop the one team that seems to love the hard compound Pirelli tire.

Infiniti hires Sebastian Vettel as Director of Performance

Remember when, during the Grand Prix of the Americas weekend last November, we told you that Sebastian Vettel had worked with Infiniti on the new G Coupe and that there'd be more of that kind of involvement on the way? It's been made official with the three-time Formula One World Champion being named Infiniti's Director of Performance.
Although the announcement is fresh, Vettel's time on the job isn't, Infiniti saying that Vettel went to Japan, the Nürburgring and the Circuit de Catalunya to assist in the development of the Q50 sedan.
When we spoke to Andreas Sigl, the man in charge of Infiniti's F1 collaboration with Red Bull, about the tie-up he had also said, "Like Mercedes has AMG and BMW has M - whether it's called IPL or not - we want to have something in that space." If the brand is still serious about that, Vettel's chops could help them deliver the kind of performance they'd need as upstarts to challenge the ringleaders of that particular hi-po circus.
