Nissan 370Z Nismo races man in wingsuit

For its latest ad, Nissan brought together a racecar driver in a 370Z Nismo, a BASE jumper in a wingsuit and a Juke crossover with three computer screens to the Susten Pass in the Swiss Alps. As odd as the combination sounds, the ingredients come together quite nicely for an action-packed display of man versus machine in a race to the end of the pass.
No, the Juke didn't race. Nissan left that to 2012 Nissan GT Academy Champion Peter Pyzera in the 370Z, who diced his way down the windy mountain pass. Pyzera faced renowned BASE jumper Dave Barlia in the wingsuit, who jumped off a cliff and relied merely on gravity and lift to rocket down the side of the mountain.
The Juke we mentioned earlier, known as the JukeRide, played an important role in the event, but you'll have to find out by watching the set of videos we provided below, which includes the commercial and behind-the-scenes footage. If you like what you see, rejoice; Nissan says there will be more short films like this to showcase its Nismo cars and athletes.

Gran Turismo vs reality as Red Bull pro-gamer takes on Nismo pro racer

The last time we saw a real racing driver pitted against a professional gamer, Viagame threw one of each in a Renault Megane RS and the contest was staged as the pro driver navigated the Circuit de Catalunya in Barcelona. That could be seen as a handicap for the gamer, since he's got to get his drive on while dealing with all sorts of unfamiliar G-force sensations that are out of time with what he's doing. Even so, the gamer won.
Nismo has taken its turn, running almost the same contest at Silverstone in the UK. This time, though, it has put its GTAcademy Driver and pro driver Wolfgang Reip in a car by himself, while Red Bull pro gamer Erik Leštach gets to play Gran Turismo 6 safely locked down in the pits. With each driver in his chosen milieu, the game is afoot.
You can find out who won by watching the video below, and for a chance to win something yourself, Nismo will send a box of goodies to whomever guesses the winning time in the video's comments on YouTube.

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.
