A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Nissan Note getting a little louder with Nismo versions this fall

Nissan's Nismo performance division has been getting more chances to shine recently with tuned models like the Juke Nismo RS and GT-R Nismo. But its latest creation moves closer to the bottom of the Japanese brand's lineup to make a hot hatch out of the (Versa) Note.
At least in Japan, the new model is due this fall, and Nismo is keeping a lot of the details about its latest creation a secret for now. What we do know is that it'll be available in two trims - the Note Nismo and the sportier Nismo S. "The development concept of this model was to build a car that makes you want to keep driving, no matter where your destination may be," said the division's chief product specialist, Hiroshi Tamura, in the company's announcement.
Aesthetically, the Note Nismo looks the way a tuned Nissan should, with the division's signature red trim outlining the car. It also wears a new, mesh grille, lower air dam, red side sills and rear spoiler. Inside, the S gets standard sport seats with full Recaro buckets as an option. Nissan didn't release technical specs for either version, but it promises that the S also gets a tuned engine with a five-speed manual.

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.
