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.

Nissan teases New York-bound 2015 Murano

It was over a month ago when we received reports that Nissan would be unveiling the new Murano at the New York Auto Show next month. Now the Japanese automaker has confirmed its imminent arrival, offering up the brief teaser clip below to give us a very faint idea of what to expect.
In announcing the Murano's upcoming debut in Manhattan, the company described the Murano as "the halo vehicle for Nissan's expanding range of bold crossovers and SUVs," previewing the design that will distinguish a whole range of Nissans to follow.
Short of that, we've got little to go on, but we're expecting to see some traits from the Resonance concept of 2013 Detroit vintage finding their way onto the production version of a vehicle that has always been rather stylized from the start. Something (sales figures, perhaps?) tells us that the oddball CrossCabriolet will get lost along the way, not that we'll mind.
