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.

Infiniti Q50 Eau Rouge to cost over $100,000?

Enthusiasts have been clamoring for Infiniti to build a car like the Q50 Eau Rouge for years. In concept form, it employs the GT-R's much-loved 3.8-liter twin-turbo V6, tuned to produce 560 horsepower and 442 pound-feet of torque, with the whole works slid underneath fetching luxury sedan bodywork with carbon fiber aero aids. At this point, the model is rumored to be all but certain for production. The company recently even put Sebastian Vettel in one to show it off. However, Infiniti President Johan de Nysschen is suggesting that the model's lifetime could be brief, limited and rather expensive.
The Infiniti boss recently gave a long interview to Motor Trend that spilled a lot of beans about the Eau Rouge. While he refused to officially admit that the super sedan was on the way, he admits that he's "pushing the Eau Rouge concept for commercialization."
According to de Nysschen, if built, the production version will hew closely to the concept with the engine from the GT-R, but the seven-speed automatic transmission and all-wheel drive system will come from the Q70. And while that would make the Eau Rouge a performance powerhouse, it might also be a rarity on the road:

Genesis G70 vs sport sedan rivals: How it compares on paper

We got our first look at the Genesis G70 sport sedan today. We think it looks good, with enough ties to its fellow Genesises (Geneses?) to further establish the brand and just enough distinction to help it stand out from the crowd. But ah yes, the crowd. Although Genesis didn't release the G70's full spec sheet, it revealed just enough for us to start sizing it up to its future competition. There are certainly others with which to compare (Lexus IS, Cadillac ATS, Alfa Romeo Giulia, Jaguar XE just to name a few), but we decided to take a look at the best sellers and most competitive luxury sport sedans. (And hey, if you like this, we can always do a follow up) So, here we have the Genesis G70 vs BMW 3 Series vs Audi A4 / S4 vs Mercedes-Benz C-Class vs Infiniti Q50. Nothing like a good chart to dig your teeth into on a Friday. Note that we only compared those models that line up with the G70. So, we left out the BMW 320i and Audi A4 Ultra entry level models as well as the Q50 3.0t mid-grade model that's considerably cheaper than the German performance upgrade models we listed. All 0-60 figures are rough estimates based on several sources, models/drivetrains and OEM figures.
