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.

Fiat contemplating sub-brand to compete with Dacia, Datsun

You can add Fiat to the admittedly short list of automakers considering a low-cost brand to rival Dacia. The inexpensive Eastern European brand from Renault-Nissan has performed on the balance sheet like a premium model line, and the money the alliance is taking off the table is encouraging other players to deal themselves in. Pretty soon Nissan's Datsun sub-brand will join the Dacia party, going on sale in Russia, Indonesia and India and will claim even more rubles, rupiahs and rupees for the parent company. Volkswagen recently said it will make a decision this year on a budget line for the Chinese market. With the euthanasia of Lancia and plans to move the Fiat brand upmarket, company CEO Sergio Marchionne wonders aloud to Automotive News Europe whether there could be room for a new budget brand underneath Fiat.
We're told that the initiative has been in the idea box for five years and even moved to the stage of name considerations, like Innocenti, but worries about profit kept it from realization. If such a range were to be developed, Marchionne says it couldn't be built in Italy and stay within budget, and the company is "analyzing its manufacturing capacity outside of Europe to see if a low-cost brand is viable."

Carlos Ghosn to make first public appearance in seven weeks on Tuesday

Ousted Nissan chairman Carlos Ghosn is set to make his first public appearance in seven weeks at a Tokyo court on Tuesday after he requested an open hearing to hear the reason for his continued detention. Ghosn has been held in a detention center since his Nov. 19 arrest on allegations of financial misconduct, which was followed by re-arrests over further allegations. The hearing will take place at 10:30 local time (0130 GMT) on Jan. 8, the Tokyo District Court said on Friday. The reason behind the timing of Ghosn's request was not clear. Earlier this week, the court approved an extension to Ghosn's detention until Jan. 11, after re-arrest by prosecutors who accuse him of aggravated breach of trust in transferring personal investment losses to Nissan. Those allegations center on the use of company funds to pay a Saudi businessman who is believed to have helped him out of financial difficulties, sources said last week. According to an article from The New York Times, Ghosn and his family assert that he is innocent. In remarks Ghosn made while under detention in Japan, he is reported to have said through his lawyer, "I want to have my position heard and restore my honor in court." Former Nissan executive Greg Kelly, who has been charged with conspiring to under-report Ghosn's income, has been released on bail after the court ruled against extending his detention while he awaits trial. Ghosn's arrest was followed by his removal from roles at Nissan and Mitsubishi. The case has rocked the auto industry and strained Nissan's ties with French partner Renault where Ghosn still remains chairman and chief executive. Renault has launched a search for an interim chief to fill Ghosn's roll at the French company as he deals with these legal cases in Japan. The arrest has also put some of the practices of Japan's criminal justice system under international scrutiny, including keeping suspects in detention for long periods and prohibiting defense lawyers from being present during interrogations.
