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.

Panoz and DeltaWing suing Nissan over BladeGlider concept

Similarity is bound to occur in an industry where most of the products follow the same basic formula. But once in a while a new design comes along that doesn't quite reinvent the wheel, but comes pretty damn close. The DeltaWing project was one such design - and Nissan, the car's designers allege, stole that design.
After the DeltaWing proposal was rejected by the IndyCar series, its creators took it to Le Mans and brought Nissan on board to supply the power. Nissan subsequently pulled out of the program and came out with the ZEOD RC hybrid racer (right), bearing a suspiciously similar design with an unusually narrow front track at the end of a long nose cone, and a wider track at the back. The Japanese automaker then displayed the BladeGlider concept (below, right) at the Tokyo Motor Show, envisioning a translation of the same formula into road-going form.
The similarity did not escape Don Panoz, who - after making sports and racing cars under his own name and founding the now-defunct American Le Mans Series - was a central figure in bringing the original DeltaWing to life. Now Panoz has filed a lawsuit against Nissan, soliciting the courts to issue a cease-and-desist order on both the ZEOD RC and BladeGlider projects, naming Nissan motorsport chief Darren Cox and Ben Bowlby (who defected to Nissan from the DeltaWing program) as part of the suit.

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.
