2014 Nissan GT-R Track Pack squares off against Audi R8 V10 Plus

The team over at Motor Trend has pitted the new Audi R8 V10 Plus against the Nissan GT-R. While both of the bright red all-wheel-drive supercars are comparably matched in power output, the similarities end there. Audi offers a mid-engine aluminum coupe with a naturally aspirated V10 that spits out 550 horsepower. Nissan shows up with a more traditional coupe equipped with a 545-horsepower twin-turbocharged V6 at the front of the car.
The Head-to-Head video takes both cars to the Streets of Willow Springs in the California desert for some track work with professional racing driver Randy Pobst behind the wheel. After a day at the track, the pair head to the local mountains for some spirited real-world driving. One dominates on the circuit, while the other earns back its credibility in the canyons. We won't tell you which coupe comes out on top, but we think you may be surprised. Follow the link below to watch for yourself.

Nissan reveals updated 2015 370Z Nismo among the faithful

Well before quick Honda Si models of the '80s or the performance juggernaut that the Toyota Supra and Mazda RX-7 became in the 90s, the Datsun 240Z was an early stake in the ground for Japanese sports cars. It was affordable, but the original Z-car was also a capable coupe that could show its tail to European and American rivals. Today, Nissan celebrates the car each year with fellow enthusiasts at its ZDAYZ event, and this year in North Carolina, it's surprising fans by launching the 2015 370Z Nismo there with some significant upgrades.
The biggest change is that the 370Z Nismo is available with a seven-speed automatic transmission for the first time. The six-speed manual is still standard, of course. But for those who don't want to use a clutch, Nissan is offering the new automatic with Downshift Rev Matching and a manual mode via paddle shifters. Power is still provided by the same 3.7-liter V6 as last year, producing 350 horsepower and 276 pound-feet of torque with a limited-slip differential at the back for added traction.
This hottest 370Z model also receives a brand-new GT-R-inspired bodykit that features a deeper front fascia, LED running lights and blacked-out headlight bezels. It also sports a new chin spoiler bearing the Nismo emblem and red accents that flow from the front, down the side sills and all the way to the rear bumper. At the back, there is also a smaller ducktail spoiler for a more mature look. The 2015 also wears cool 19-inch forged aluminum wheels by Rays with a new twin-spoke design and charcoal finish. Compared to last year's model, it's a much more mature-looking coupe.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
