'Nothing is blocking' Nissan alliance talks, says Renault chairman

TOKYO — Nothing is blocking discussions between Nissan and Renault over the future of their alliance and the two companies will have "important talks" on Tuesday and Wednesday, the French automaker's chairman said in Tokyo. Speaking at an event on Tuesday, Renault SA chairman Jean-Dominique Senard touted the Franco-Japanese alliance, which has been discussing ways to revamp the relationship. The companies had initially set Tuesday as a deadline to hammer out a deal. However, the discussions have taken longer than originally expected due to Nissan's concerns about how its intellectual property rights can be protected as Renault forges new ties with China's Geely, sources have told Reuters. Renault last week unveiled a sweeping overhaul of its businesses, saying it would set up a joint venture with Geely for gasoline engines and hybrid technology and spin off its electric vehicles unit next year. It wants Nissan to invest in the new electric unit. The companies are also renegotiating their equity ties, which currently see Renault owning a controlling 43% of Nissan and the Japanese company holding only a 15% non-voting stake in Renault. "Nothing is blocking" the discussions, he told reporters after the event, declining to say when the alliance members would reach a deal and adding "you will be informed on time." "As the chairman of this alliance, I've never lived such a warm atmosphere within the alliance and this bodes well for the future."   Green Mitsubishi Nissan Renault

Nissan reveals new Qashqai crossover for Europe

Between the Juke, Rogue, Murano, Xterra, Pathfinder and Armada, Nissan offers a wide variety of crossovers and SUVs in this market. And that's not even counting the trucks, vans and Infiniti crossovers. But in the European market, it all comes down the Qashqai. Not that Nissan doesn't offer other crossovers in Europe, it's just that the Qashqai has, since its introduction in 2007, accounted for the lion's share, with over two million sold globally (of which 1.5 million were in Europe). And now, after teasing it repeatedly, Nissan has introduced the all-new model.
Larger, sleeker, more advanced, more comfortable and more environmentally friendly than the model it replaces, the new Qashqai is designed in Europe, for Europe, and hits the market at the start of the new year. It's the first European model to be based on Renault-Nissan's new Common Alliance Platform that will eventually encompass three Nissan models and 11 Renaults built in locations around the world.
An array of gasoline and diesel engines, ranging from 110 to 150 horsepower, will be available in two- or four-wheel drive configurations, with either a six-speed manual or the type of continuously variable transmission which Nissan champions.

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.
