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.

Ex-Nissan chairman Carlos Ghosn indicted, may remain in jail for months

TOKYO — Nissan's ex-chairman Carlos Ghosn was charged Friday with breach of trust, according to the Tokyo District Court, making the star executive's release unlikely for months. Ghosn, arrested Nov. 19, was earlier charged with falsifying financial reports in underreporting his income by about 5 billion yen ($44 million) over five years through 2015. Ghosn; Greg Kelly, another Nissan executive; and Nissan as a legal entity also were charged Friday with additional underreporting of income, from 2015 through mid-2018. Ghosn's lawyer Motonari Ohtsuru said he would request that Ghosn be granted release on bail. His detention period for the breach of trust allegations was due to expire Friday. Kelly and Nissan were not charged with breach of trust. Those allegations center on Ghosn's handling of investment losses and payments made to a Saudi businessman. Ghosn, 64, says he's innocent. Suspects in Japan are routinely held for months until trials start, and Tokyo prosecutors maintain that Ghosn, a Brazilian-born Frenchman of Lebanese ancestry, is a flight risk. Earlier this week Ghosn told a Tokyo court he was innocent, in his first public appearance since his arrest, and appealed for his detention to end. But the court rejected that request. "I have a genuine love and appreciation for Nissan," Ghosn told the court. "In all of my efforts on behalf of the company, I have acted honorably, legally and with the knowledge and approval of the appropriate executives inside the company." He said the compensation was never decided on, the investment deal never resulted in any losses to Nissan, and the payments to the Saudi businessman were for legitimate services related to dealers and investments in the Gulf. Ghosn, who appeared much thinner than before his arrest, came down with a fever the day after his court appearance, but has since recovered, Ohtsuru, the lawyer, said. His wife Carole Ghosn issued a statement overnight out of Paris, expressing concern over his sickness. "I am pleading with the Japanese authorities to provide us with any information at all about my husband's health. We are fearful and very worried his recovery will be complicated while he continues to endure such harsh conditions and unfair treatment," she said. Apart from prosecutors, only embassy officials and Ghosn's lawyers are allowed to visit him. Such visits were canceled Thursday but resumed Friday.

Apple iTunes Radio picks Nissan as first automotive launch partner

With the launch of iOS 7 last week, those who carry around a certain fruit-branded cellphone got access to a new technology called iTunes Radio. Apple's delayed entry into a market currently dominated by service such as Spotify and Pandora, iTunes Radio allows users to create their own stations or to choose from a number of featured stations. From there, listeners can fine tune their results to deliver more popular songs or newer, deeper tracks. Each song is linked back to the iTunes store, allowing users to easily buy songs they fall in love with.
Now, Nissan has teamed with Apple as the exclusive launch partner for iTunes Radio. This partnership means you'll be seeing some Nissan-specific content when you're surfing through iTunes Radio, with some subtler stuff in the form of material and some not-so-subtle approaches, like Nissan's use of iAd, a system that allows developers to directly insert advertisements into apps. The focus at first will be on the upcoming Rogue, the redesigned Versa Note and the Leaf EV.
Nissan's vice president of marketing in North America, Jon Brancheau, explained the team up, saying, "We see iTunes Radio as an integral part of our new vehicle launches and 'big moments,' riding the wave of interest and usage of this exciting new service to maximize exposure of Nissan's new models." Take a look below for the rundown from Nissan.
