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.

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.

Japanese automakers kick in $800k for new charging-station company

Cynics may say that gathering $800,000 (total) from four of Japan's largest automakers is merely a rounding error. Still, Toyota, Nissan, Honda and Mitsubishi, along with the Development Bank of Japan, are putting those funds to good use. So, that's something. Last week, those five entities officially founded Nippon Charge Service LLC. The company was established to promote plug-in vehicle charging installations across Japan and the automakers seeded it with 80 million yen, or about $786,000 US. Those funds will be used to help business owners deploy charging stations at convenience stores, highway-side locales and other locations that will make it easier for plug-in vehicle drivers (of Toyotas, Hondas, Mitsubishis and Nissans, obviously) to get their juice. The automakers first announced they'd collaborate last year, when they said they'd work with the Japanese government to more than triple the country's publicly accessible chargers to about 17,000 units. No targets were disclosed as far as how many charging stations would be deployed this time out, but, in a move similar to the EZ Charge system in the US, Nippon Charge Service will also have universally-accepted charging cards available by the end of the year to drivers all of those brands' plug-in vehicles to make the charging process a little more seamless. Check out Honda's press release below. Japan Automakers Advance Electric Charging Infrastructure with New Company, Nippon Charge Service -Established to help build charging infrastructure for electric-powered vehicles (PHVs, PHEVs and EVs)- Toyota Motor Corporation Nissan Motor Co., Ltd. Honda Motor Co., Ltd. Mitsubishi Motors Corporation Development Bank of Japan Inc. TOKYO, Japan, May 30, 2014 - Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation jointly established a new company, Nippon Charge Service, LLC, on May 26 to promote the installation of chargers for electric-powered vehicles (PHVs, PHEVs, EVs). The goal is to help build a charging network that offers more convenience to drivers in Japan. The new company will promote the installation of chargers, for the good of society and to expand the use of electric-powered vehicles. Related industries are also expected to benefit.
