Did Nissan send a ringer GT-R to run the 'Ring? [w/video]

It turns out that after toting a 7:08 time around the fearsome Nürburgring Nordschleife for the new Nismo-tuned GT-R, Nissan might not have been entirely honest about the car it was using. From what we've been hearing from a few different publications, the GT-R featured in the video isn't what we're going to see on the production model.
PistonHeads reported on the so-called "Time Attack" GT-R while it was in Japan for the Tokyo Motor Show, going so far as to detail the differences between it and the standard GT-R Nismo. And friends, this isn't just a matter of swapping tires. The mods made to the Time Attack car are far more comprehensive.
For a start, the TA produces more downforce thanks to larger aerodynamic pieces. It's some 110 pounds lighter than the standard car, thanks to new bucket seats. The ECU and dampers have been swapped for new units, and the brake pads are different as well. If you've read this far, you might be feeling slightly angry or betrayed that Nissan is toting numbers for a modified car. Don't be.

Wards names its 2015 10 Best Interiors list

Wards Automotive has named the winners of its 10 Best Interior awards, covering a wide but affordable array of vehicles. Where last year's list contained two six-figure vehicles, including the $372,800 Rolls-Royce Wraith, this year's is, well, a whole lot more reasonable. The publication lists the Mercedes-Benz C400 at $65,000 (which seems off), making it the most expensive vehicle here. That said, we'd argue that the entire C-Class line deserves to make this year's list, owing to its varied and high-quality selection of materials. The other vehicle to break the $60,000 mark, meanwhile, is the $60,675 Ford F-150 King Ranch, which has 327,000 pounds of leather lining its interior. Only one other German car, the BMW i3, and one other pickup truck, the GMC Canyon, managed to make this year's list. Here's the full list of this year's winners: 2014 BMW i3 ($52,550) 2015 Chrysler 300C Platinum ($51,175) 2015 Ford F-150 King Ranch ($60,675) 2015 GMC Canyon SLT ($40,465) 2015 Honda Fit EX-L ($21,590) 2015 Jeep Renegade Limited ($33,205) 2015 Kia Sedona SXL ($43,295) 2016 Mazda6 Grand Touring ($33,395) 2015 Mercedes C400 ($65,000) 2015 Nissan Murano SL ($41,905) See what we mean about the mainstream vehicles? Not only is there a distinct lack of luxury brands, it's the price of some of the vehicles that surprise. The Honda Fit, Jeep Renegade and Mazda6 are very reasonably priced, especially when you compare Wards price with the starting price. The Renegade Limited starts at less than $25,000, the Mazda at less than $22K and the Fit at under $16,000. Head over to Wards for a more detailed explanation of why each vehicle won.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
