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 to display special Q60 convertible celebrating Unser at Amelia Island

Bobby Unser is one of the great American racing drivers of his generation, having won the Indianapolis 500 in 1968, '75 and '81 and belonging to the Unser racing dynasty. But he might be getting the oddest tribute of his life at the 2014 Amelia Island Concours d'Elegance. Infiniti has created a tribute to his Indy-winning 1968 car out of a Q60 Convertible (previously the G37), and he will be driving it around the event.
The Infiniti is wrapped in red, gold, black and white livery with the number 3 designed by the company's design director Alfonso Albaisa. While the connection seems dubious, Offenhauser-powered racecars are one of the featured vehicles at this year's concours, and the Japanese luxury automaker worked with the Indianapolis Motor Speedway Hall of Fame Museum to bring Unser's 1968 Eagle, which used an Offenhauser engine and flew those colors, to the show. The brand wanted a car of its own to match... no matter how outlandish it looked.
Honestly, while certainly a nice gesture, the choice still seems a bit weird. At least visitors will get the chance to see American racing royalty and his winning car. Scroll down to read Infiniti's full explanation for their effort.

Infiniti Pebble Beach retro concept is a '50s-inspired electric grand prix car

Infiniti will debut a retro-inspired race car at next week's Pebble Beach Concours d'Elegance that combines the style of classic grand prix open-wheel cars with modern design elements and powertrains. The car should fit right in at Pebble Beach alongside all the vintage machinery from the early days of motorsports. Simply dubbed the Infiniti retro prototype, it is Infiniti's idea of what could have been. Basically, the Japanese automaker imagined that it found a car hidden away for 70 years in southern Japan. They took that old look and married it with the brand's "Powerful Elegance" design language. We only have a couple of photos, but it looks like a sleek silver bullet with narrow-section bias-ply tires. We'll have to wait until next week to see the entire thing, but this teaser has us excited. As expected with any modern concept, the retro prototype eschews an awesome multi-carb gasoline engine in favor of Infiniti's EV technology. It's unclear if the car actually runs, but we'd all love to see this put some laps down at nearby Mazda Raceway Laguna Seca. Related Video:
