Watch a Nissan GT-R make up 17 spots on the first lap

By now, enthusiasts should be plenty used to seeing the Nissan GT-R passing "lesser" vehicles on the road - and let's face it, that accounts for a good 99-percent of other cars out there. But what about on the racetrack, where GT racers are all homologated to the same general specifications and tuned with an eye toward fairer competition?
Turns out Godzilla is just as formidable an adversary on the track, as demonstrated by this latest video. Shot from inside the cabin of British driver Alex Buncombe's GT3 racer during the Blancpain Endurance Series race at Monza, the video shows what happens (or at least happened this time) when a well-driven GT-R is relegated to the back of the grid - even when that grid is populated by the likes of Porsche, Aston Martin, Lamborghini and McLaren.
Buncombe and his teammates in the Nissan GT Academy Team RJN ultimately finished the race in 13th place, but what's remarkable is that they started way back in 32nd, making up 17 places on the first lap alone. Scope out the frenetic action in the video below.

Nissan lowers price of seven models for better search results

Intent on not eliminating itself from consideration, and adapting to the way consumers research new car purchases, Nissan has announced price discounts now in effect, indefinitely, on seven models: the Altima, Armada, Juke, Maxima, Murano, Rogue and Sentra. It was found that Nissan's price points fell outside the competitive pool when prospective buyers searched for cars based on maximum price.
The price cuts vary and depend on the equipment spec, but they range from several hundred dollars to thousands of dollars; the MSRP of the Altima drops by $580, the Sentra by $730, the Armada by $4,400. Discounts on the Murano alone range from $1,460 to $2,410. Under orders from CEO Carlos Ghosn the brand is working to raise its US market share to ten percent by 2016, from 7.9 percent currently - which includes Infiniti - and appears to be optimizing its placement every step of the way to do so.

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.
