Nissan GT-R Nismo 'Ring time makes it track's 'fastest volume production car' [w/video]

Performance cars are fun to drive and all, but at the end of the day ,owners drop big bucks on what are often ridiculously unpractical vehicles for the bragging rights. And when it comes to ultimate bragging rights, few get more publicized than lap times for everyone's favorite stretch of German pavement, the Nürburgring. Enter the 2015 Nissan GT-R Nismo.
After rumors about a 7:08 lap time appeared yesterday, Nissan confirmed has confirmed the news today with video footage of the run, which took place on September 30. The official lap time is just seven minutes and 8.679 seconds, putting the GT-R Nismo about 11 seconds off the pace of the Porsche 918 Spyder - some six seconds quicker than the far costlier Lexus LFA. Some admitted - but hard-to-spot - missteps by Nissan driver Michael Krumm would indicate that the car actually left some time on the table.
With this time, Nissan claims that the 595-horsepower GT-R Nismo is the "fastest volume production car" around the track. The definition of "volume" could surely be contested here, though, considering the small numbers in which the GT-R is sold. While we don't have global GT-R sales figures, this year has only seen 1,063 units sold through October, and there were close to 1,300 sold in all of 2011 and about 1,200 in 2012. While this loosely defined claim will only add to the Nürburgring lap time squabbling, it is no less impressive. Check out the record run for yourself in the video below, which is accompanied by an official press release.

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.

Did Amazon just deliver a car in a giant box?

Back in September, reports started rolling in that Amazon would get into the auto sales business after a promo for the Nissan Versa Note appeared on the online retailer's page. That link didn't actually sell a car, but instead acted as a referral service for potential customers, linking them up with dealers. A recent image that's been floating around on Reddit and that was picked up by The Huffington Post, though, has us wondering if Amazon has dove into the actual business of selling cars, rather than just referring people to dealers.
The image, above, shows an enormous Amazon box on the back of a flatbed tow truck. According to HuffPo, this could be one of the cars sold through the earlier promotion for the Versa Note (which was sweetened with the addition a $1,000 Amazon gift card). Apparently, three of the Versas purchased would arrive in such a fashion. Then again, this could all be nothing more than an elaborate publicity stunt. Amazon is, after all, the company has been touting drone delivery of its goods.
What do you think is in the box? Let us know down in Comments. Bonus points for those that come up with an idea as absurd as the bulk order of banana slicers HuffPo mentioned.
