Nissan to bring Friend-Me concept to Shanghai

Nissan's got a big ol' show planned for its immersive space at the 2013 Shanghai Motor Show where visitors will see, touch, hear and smell the Nissan world. Sitting among 20 offerings that include the GT-R, Quest, Murano and Teana will be the Friend-Me concept (click image above to enlarge), the first show car created with "key input" by Chinese designers at Nissan Design China in Beijing. Its USP is "Four seats, one mind connectivity" that promotes information sharing among all the occupants.
The Friend-Me has the "vibrant, young" Chinese demographic in mind, our guess being Nissan thinks there's no reason to stop the digital sharing just because you're sitting in a car. We'll find out on April 20 exactly what's being exchanged in the Friend-Me. Until then, there's a press release below with a little more info.

PSA shares rise following FCA's breakup with Renault

Shares in Groupe PSA, parent company of automakers Peugeot, Citroen and the DS brand, rose on Thursday as analysts considered the possibility that Fiat Chrysler could turn back to PSA after withdrawing its $35 billion merger offer for Renault. "Both parties have acknowledged the need for scale or [mergers and acquisitions] and may pursue other opportunities. If Nissan was an obstacle (to an FCA-Renault deal) PSA-FCA discussions could resume," wrote brokerage Jefferies. Back in March at the Geneva Motor Show, rumors started swirling that PSA was interested in a potential merger with FCA. Mike Manley, who took over at the helm of Fiat Chrysler following the death of Sergio Marchionne, had indicated a willingness to look into potential partnership options. Of course, that was all before FCA proposed a merger with Renault — with that deal now off the table, attention naturally turns back to PSA, which is also based in France. "We expect both shares to react negatively but see FCA having wider strategic options and Renault shares more downside risk near-term," said Jefferies. According to Reuters, PSA shares were up 1.5% at the time this was published, making it the top-performing stock on France's benchmark CAC-40 Index. Renault saw its shares slump 7%. Shares for FCA fell 3% in early trading on the Milan Stock Exchange. Considering that FCA said in its statement confirming the withdraw of its merger offer with Renault that "political conditions in France do not currently exist for such a combination to proceed successfully," we have to wonder how keen the company is to begin negotiations with another French automaker like PSA. Those thoughts were similarly voiced by Bernstein Research analyst Max Warburton, who said (via Forbes), "Expect PSA to rise on unrealistic hopes it may be FCA's next date."

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.
