Nissan's purchase of Mitsubishi is officially official

After the company's announcement in May, the Nissan's purchase of a 34 percent stake in Mitsubishi is now official. The deal cost Nissan $2.3 billion, according to the Wall Street Journal, and brings Mitsubishi into the Nissan-Renault Alliance. The company explained that this new partnership will manifest itself in shared vehicle platforms and technology, joint purchasing, and shared manufacturing. Nissan also said that this purchase will make the company one of the three largest companies by volume in the world. Nissan also emphasized that Mitsubishi will very much be a partner in the current alliance with Renault. In addition, Carlos Ghosn, CEO of both Nissan and Renault, has been nominated to be the new chairman of the Mitsubishi board. With Ghosn at the head of the board, current Mitsubishi president and CEO, Osamu Masuko, will remain in his positions but Nissan's current chief competitive officer will join Masuko as co-chief executive officer at Mitsubishi. With these companies now working together, we'll probably start seeing more commonality between Nissan and Mitsubishi products here in the States. It would also be a great opportunity to get some of Mitsubishi's cooler products here. Perhaps Mitsubishi and Nissan will take our hint about the Delica. This article has been revised to clarify that Nissan Motors purchased the stake in Mitsubishi, not the Nissan-Renault Alliance, and to add the value of the purchase.

Nissan Leaf resale value expected to take a hit

Nissan Leaf resale values may take a tumble, according to Kelley Blue Book. The vehicle evaluation resource said the 2013 Nissan Leaf will retain around 35 percent of its MSRP after three years; that's down five percent from what KBB gave the 2012 Leaf at the end of 2011. Automotive News reports KBB adjusted the EV's residual value prediction because the used transaction prices for the 2011 model have stuck around 35 percent for the past few months due to relatively cheap gasoline, not to mention the fact that Nissan trimmed the electric's MSRP from $36,050 to $29,650 before the $7,500 tax credit.
Since used buyers are often motivated by more practical buying concerns than early adopters or those wanting to curb their carbon emissions, they may not be willing to pay more for an EV. Meanwhile, early Leaf models are now coming to auction, abandoned by rental car companies after customers shunned them in favor of traditional internal-combustion vehicles. Many of those at auction have less than 10,000 miles and carry an average transaction price of just $13,700.

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.
