Nissan moving next-gen Murano production from Japan to Mississippi

Celebrating 10 years of operation at its Canton, Mississippi assembly plant, Nissan has announced that it will be adding a seventh vehicle to the plant's portfolio. Starting in 2014, production of the next-generation Murano will move from Japan to Mississippi alongside its platform mate, the Altima, which is a part of Nissan's plan to build 85 percent of its US products domestically.
In addition to the Altima, the Canton facility also produces the Armada, Xterra, Titan, Frontier and NV vans, and back in June, production of the Nissan Sentra production was moved to Canton creating an extra 1,000 jobs. At this point, there is no indication about how many jobs the Murano line will add, if any.
This is the second announcement this week of production being added in the US as Honda said that the Accord Hybrid production would move to Marysville, Ohio where the standard Accord sedan is currently built.

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.

Ghosn: Restoring Mitsubishi's reputation is biggest challenge

After news that Mitsubishi falsified its fuel economy data on every vehicle it has sold in Japan since 1991, and the tumble in the company's value that followed, the troubled carmaker has an unlikely savior. Nissan has confirmed it will purchase over one third of Mitsubishi's stock, or 34 percent. The stake is valued at $2.2 billion. Ghosn says making Mitsubishi a part of the Renault-Nissan alliance will save billions in development costs. But the merger certainly isn't without challenges. "The biggest challenge is to support Mitsubishi changing itself and growing and being profitable and restoring its reputation," said Ghosn. Nissan is a natural partner for Mitsubishi, and since the fuel economy scandal escalated from discrepancies in the data regarding Mitsubishi-manufactured, Nissan-badged Japan-market vehicles, it makes sense for the company to sweep in and save the day. Nissan itself is partially owned by Renault, and Nissan has a 15-percent stake in the French automaker. Mitsubishi's chairman, Osamu Masuko says that the merger was inevitable, that it "would have happened one day" anyway, according to the New York Times. Carlos Ghosn, chairman of both Nissan and Renault, is confident they will be able to turn Mitsubishi's fortunes around. "We have the track record to make it work", Ghosn said, referring to the Renault-funded rescue of Nissan in the early 2000s. Related Video:
