Nissan union wants French to stop meddling with Renault alliance

Nissan is getting some unexpected reinforcements in its ongoing battle with the French government over its involvement in Renault. Its Japanese union, which has traditionally been a very hands-off entity, issued harsh criticism for the French government's attempts to assert control over its alliance partner. According to Bloomberg, this is the first time in 16 years that Nissan's union has weighed on the company's affairs, and it's stating its position on the matter in no uncertain terms. The union called France's attempt at scoring double voting rights within Renault "unacceptable and against the intended spirit of the Alliance." "We support the numerous attempts of Nissan to engage with the French government to find a balanced and constructive solution that will benefit and strengthen the Alliance," the union said in a statement obtained by Reuters. It's unclear what impact the union speaking out will have on the current power struggle between Renault-Nissan CEO Carlos Ghosn (shown above) and the French government, but we doubt it'll contribute to any quicker of a conclusion.

Nissan rowed the Note ashore [w/video]

Normally we wouldn't suggest trying to float your car on water, but Nissan has made some modifications to turn its new Versa Note hatchback into a makeshift rowing shell.
Nissan replaced the car's rear seats with a sliding rear rowing seat, modified the doors to open wider at 90 degrees and fitted a pair of oars. Most importantly, they put the whole thing on a floating platform to keep it from sinking into Eton Dorney Lake, the site of the 2012 Olympic rowing competitions in England (where the car is simply known as the Nissan Note).
Then they invited medal-winning competitive rowers Helen Glover, Sophie Hosking and Polly Swann to come along and row the thing, making use of the around-view monitor system to see where they were going. All in all it may not be quite as cool as the boats which Fiat made out of the 500 or Mini made out of its convertible, but it's still enough to float our boat. Check it out in the video clip and press release below and the image gallery above.

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.
