Nissan bringing Qashqai, Rogue hybrid to US

Nissan will be expanding its crossover range here in the United States, introducing the popular European-market Qashqai, alongside a hybridized version of the Rogue. Nissan's Kyushu, Japan factory, meanwhile, will churn out 100,000 gas-powered Rogues to capitalize on hot demand here in the United States. The Kyushu move, at least, seems like a smart one, considering just how hot the compact Rogue is. "We haven't hit the ceiling [on Rogue] yet. We have more opportunity there if we can get our dealers more," Fred Diaz, Nissan's senior VP of sales and marketing, told Automotive News. Amping up production in Kyushu will finally mean the end of the first-generation Rogue, though, now known as the Rogue Select. Somehow, we doubt many tears will be shed. AN cites "two sources familiar with Nissan's future product" in its report on the Qashqai and Rogue Hybrid, although both moves are a bit strange at first glance. Both vehicles play in the same part of the market, and are both based on the Renault-Nissan Common Module Family platform. As for the Rogue Hybrid, well, we know what happened the last time Nissan tried to add an electric motor and battery pack to one of its crossovers. Plus, we've heard this rumor before. Nissan, though, seems to think both moves make a lot of sense. While the Qashqai and Rogue are closely related, the Euro-market model is smaller – 10 inches shorter and two inches narrower – making it less versatile, and it wears more handsome sheetmetal. Expect Nissan to field it as such, aiming at buyers that want a CUV for the lifestyle, rather than the versatility, Automotive News reports. There's a lot less information on the Rogue Hybrid, aside from AN reporting that it will hit the market next year. As for potential powertrains, mum's the word. The gas-powered Rogue uses a 2.5-liter four-cylinder, which is the same size as the gas-engine found in the dead-but-still-warm Pathfinder Hybrid. While we doubt it's as simple as a drag and drop, it seems like Nissan's most recent hybrid powertrain is the obvious choice for the upcoming Rogue. What do you think? Will the Qashqai be as big of a hit in the US as it is in Europe and Australia? Is a Rogue Hybrid such a smart move considering the tremendous failure of the Pathfinder Hybrid? Speak up in Comments.

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.
