Infiniti Q50 Eau Rouge gets the heart of a GT-R [w/video]

There has been ongoing talk of an Infiniti using the Nissan GT-R powertrain practically since the moment the Nissan's flagship sports coupe hit the road. While the rumors have gone back and forth over the years, they have never completely gone away. It seems Infiniti is finally turning an ear to the screams of its most vocal enthusiasts with an updated version of the Q50 Eau Rouge concept boasting a modified version of Godzilla's engine and all-wheel drive system debuting at the 2014 Geneva Motor Show. It's even taking things a step further and granting it a new, seven-speed transmission to replace the Nissan's six-speed.
The latest evolution of the Eau Rouge packs the same 3.8-liter, twin turbocharged V6 found in the GT-R but with a unique tune of 560 horsepower and 443 pound-feet (600 Newton-meters) of torque. That makes it 15 hp more powerful than the standard 2015 GT-R but gives up 20 lb-ft of torque. Power gets to the ground through the GT-R's all-wheel-drive system. Infiniti predicts that the Eau Rouge would sprint to 60 miles per hour in less than 4 seconds and on to a top speed of 180 mph.
According to Infiniti Communications Senior Manager Kyle Bazemore in an email to Autoblog, the modded GT-R powertrain was not the only choice for the Eau Rouge. It also considered "developing a high-power sports diesel" and hybrid versions with an electric supercharger. However, "this was the clear solution for this concept car," Bazemore said. Other than the drivetrain, the Eau Rouge in Switzerland is identical to the one shown in Detroit. Sadly, it is not confirmed for production; so we might not be getting the fabled Infiniti GT-R sedan any time soon. Still, we can hope.

Nissan's plan to supply US Mitsubishi dealers with family sedan stalls

Mitsubishi has quietly had some big success recently. The Japanese brand sold 77,643 vehicles in the US for all of 2014, a 24.8 percent jump over 2013. While still relatively small overall (Ford sold 74,355 F-Series trucks just in December, for example), it shows definite growth for the sometimes forgotten automaker. Unfortunately, the latest news might not help the company's future expansion. The proposed partnership of Mitsubishi and the Renault-Nissan Alliance on at least one midsize sedan for the US market is off the table, according to Automotive News. The company informed sellers that the collaboration had fallen through during a National Automobile Dealers Association meeting. "I told them that the plan has stalled," said Don Swearingen, executive vice president of Mitsubishi Motors North America, to Automotive News. "And I said that's really all I can tell you at this time." Under the original partnership, Mitsubishi was supposed to get a D-segment sedan that would have been built at the Renault-Samsung factory in Busan, South Korea. The automakers were also negotiating for Mitsu to get a C-segment four-door as a global model and developing an electric kei car for Japan together, due in 2016. While the sedan is gone, Mitsubishi isn't completely bereft of improved products in the pipeline. The Mirage Sedan is being launched in the US, and the Outlander is supposed to get a redesign for the 2016 model year. According to Automotive News, the Outlander Sport and Lancer are also due for refreshes in 2016, and a new Mirage is on the way.

Nissan's Le Mans prototype V6 to power next GT-R

You can debate all you want about whether racing has any relevance to road cars. And while you're doing that, Nissan will be getting the most out of its GT-R LM Nismo. In fact, the latest reports indicate that the Japanese automaker will use the engine (or some version thereof) in the next-generation GT-R. The Nissan GT-R LM Nismo, for those who may have missed it, is the company's radical attempt to take on the Audis, Porsches and Toyotas of the top-tier LMP1 class in the FIA World Endurance Championship. And to do so at its flagship event, the 24 Hours of Le Mans. Only unlike its rivals, it's not a mid-engined, all-wheel-drive design; both the engine and the driven wheels are at the front end. That engine, however, isn't actually all that radical. It's a 3.0-liter twin-turbo V6 producing 550 horsepower. Potent, but nothing earth-shattering. In fact it's not far off from the 545-hp 3.8-liter unit in the current production GT-R. And according to Top Gear, in speaking with the racing program's director Ben Bowlby, it will be essentially the same engine that will power the next road-going GT-R. Now if you're thinking that something's missing here, you're right: the GT-R LM Nismo packs a lot more than 550 horses. It actually has over 1,250 on tap. The remaining 700 hp are kicked in by the electric component of the racing prototype's hybrid powertrain. The next GT-R is widely expected to incorporate hybrid technology as well, but it won't be good for 700 hp all on its own. And it will almost certainly be driving all four wheels like the current version. Related Video:
