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 to bring Friend-Me concept to Shanghai

Nissan's got a big ol' show planned for its immersive space at the 2013 Shanghai Motor Show where visitors will see, touch, hear and smell the Nissan world. Sitting among 20 offerings that include the GT-R, Quest, Murano and Teana will be the Friend-Me concept (click image above to enlarge), the first show car created with "key input" by Chinese designers at Nissan Design China in Beijing. Its USP is "Four seats, one mind connectivity" that promotes information sharing among all the occupants.
The Friend-Me has the "vibrant, young" Chinese demographic in mind, our guess being Nissan thinks there's no reason to stop the digital sharing just because you're sitting in a car. We'll find out on April 20 exactly what's being exchanged in the Friend-Me. Until then, there's a press release below with a little more info.

Renault chairman dismisses reports Nissan wants to split from alliance

PARIS — Renault Chairman Jean-Dominique Senard said on Thursday there was a "real desire" within the top ranks of both companies for its alliance with Nissan to succeed, dismissing suggestions the partnership was on the rocks. Turmoil within the Franco-Japanese alliance, long dogged by internal rivalries, deepened following the November 2018 arrest in Tokyo of its architect and long-time boss Carlos Ghosn on charges of financial crimes, which he denies. Attempts to restore calm were dealt a fresh blow by Ghosn's dramatic flight from Japanese justice and a series of no-holds-barred allegations he has made from his refuge in Lebanon, including that he was the victim of a plot to oust him and that the alliance is now a "masquerade". Nissan has vigorously rejected Ghosn's stance, while both the Japanese firm and Renault have tried to rubbish suggestions their two decades old partnership is falling apart. "We have a board overseeing the alliance which is made up of people who are all extremely in favor of the alliance," Renault Chairman Senard told a briefing with reporters. "There is a common desire to associate our strategic plans and a real desire to make this alliance a success," he added, dismissing a report that Nissan was examining scenarios for a possible future outside of the alliance as "fake news." The 66-year-old declined to comment on anything related to Ghosn, adding: "I only think about the future." Renault shares were down 2% by 1123 GMT, underperfoming the broader auto sector which was down on news that Washington has threatened to impose tariffs on European car imports due to Europe's stance on Iran. Renault's French rival and Peugeot maker PSA Group also gave a flavor of some industry headwinds, reporting a 10% fall in its global sales last year as Chinese demand tanked. Renault is due to publish its 2019 global sales on Friday. JOINT PROJECTS Analysts see Renault-Nissan's cost-saving alliance as vital to both companies as the car industry battles a slowdown and huge investments in cleaner vehicles and automated driving, particularly as rivals PSA and Fiat Chrysler are merging to help meet these challenges. Renault held ultimately unsuccessful talks to combine with Fiat Chrysler last year, which Ghosn described at a Beirut news conference as a huge missed opportunity. Senard, who chairs the alliance's operating board, said on Thursday that once the partnership has been rebooted, other firms might potentially want to join.
