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 teases Sao Paolo CUV concept, production future likely

Back in 2012 at Brazil's São Paulo Motor Show, Nissan showed off an angular subcompact crossover concept, Extrem, that seemed to to portend the future of the Nissan Juke. Now, the Japanese automaker is teasing an as-yet-unnamed CUV concept for this year's show. The new showcar, set for an October 28 unveiling, is expected to be a closer-to-production version of the Extrem ethos.
Why should we care? Autoblog has reason to believe that this vehicle is under consideration for global distribution. The production Extrem - or whatever it ends up being called - is likely to be positioned size-wise in between the Juke and the recently upsized Rogue, offering more space and still-adventuresome styling, yet at a less expensive price. If accurate, that sounds like the production model will be a fair bit larger than the conceptual Xtrem, which was built atop a modified version of Nissan's V-platform, a model that underpins its March supermini (and speaking of the March, Nissan has also teased what looks to be a sporty concept version of it for the Brazilian show, too).
It's important to note that Nissan already has a bustling small CUV portfolio globally, what with its popular Qashqai / X-Trail models in markets beyond ours. There continues to be persistent rumors that Nissan is considering bringing over the Qashqai, as well, a model seemingly already quite close in size and execution to the Rogue. Despite this, Nissan has shown no hesitation in exploring every niche of the burgeoning CUV market, and while not every derivative has been a success, models like the Juke have rewarded the company's bravery with handsome sales.

Ghosn out at Nissan, still in at Renault, still in jail in Tokyo and facing more charges

When the corporate jet carrying Renault- Nissan- Mitsubishi CEO Carlos Ghosn landed at Tokyo Haneda airport on November 19, Japanese authorities had already taken position on the tarmac, waiting for him. Police and authorities representing Tokyo prosecutor's office boarded the plane to query Ghosn about financial improprieties, and ended up taking Nissan's chairman and CEO into custody. A few days later, on November 22, Nissan's board voted to remove Ghosn from both positions for what it classified as "significant acts of misconduct." The charges include understating his income in filings to the Tokyo Stock Exchange by at least $44 million, and misusing company funds. Japanese police arrested Greg Kelly as well, the high-ranking Nissan exec said to have assisted Ghosn in the subterfuge. Ghosn and Kelly remain on Nissan's board until a shareholder vote is held to decide those positions. Kelly was Nissan's first American director, and the carmaker's former head of human resources. In France, Renault's board voted to keep Ghosn in his positions, and has requested details from Nissan about the alleged improprieties. The board put Thierry Bollore in the role of deputy CEO with all of Ghosn's powers while Ghosn is "incapacitated," and lead independent director Philippe Lagayette will act as temporary chairman. Nissan has since told Renault that it is investigating financial malfeasance at RNBV, the Amsterdam-based joint-venture company that oversees the alliance. Mitsubishi has watched from afar, only saying it will perform its own investigation, and could remove Ghosn. Tokyo police can hold a suspect for 72 hours for initial questioning without charges. With the deadline looming, Tokyo prosecutors asked the court for, and were granted, a ten-day extension. If they choose, prosecutors can request another ten-day extension. Within 23 days, however, prosecutors either need to charge Ghosn and Kelly, or release them. There are several charges that acquire more details by the day. The most serious accusation is that Ghosn understated his pay from 2011 to 2015 by half, claiming roughly $44 million in remuneration when he actually received around $88 million. Over the weekend, it came out that Japanese prosecutors could be working on new charges of Ghosn under-reporting his salary since 2015 by $27 million. A Japanese newspaper said Ghosn told Kelly in an email to lie on the financial statements.
