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 Qashai gets the Juke R treatment

It would appear that we're a little behind the times on this one, but a UK-based tuner of the Nissan GT-R is creating its own take on the lustworthy Juke-R starting with the Nissan Qashqai crossover. Severnvalley Motorsport claims to be the leading authority for tuning of the current GT-R in Europe. The outfit is now turning its attention to stuffing the drivetrain of a GT-R under the body of a Qashqai+2 - a seven-passenger compact crossover similar in size to our Nissan Rogue - resulting in the Qashqai-R.
The project started back in March when Severnvalley took delivery of a new Qashqai. After stripping the crossover down to its bare essentials and building a custom jig to support the body shell, it was then transferred onto an awaiting GT-R chassis. The crew aimed to keep Qashqai's appearance as stock as possible, but fender extensions and hood vents were required to accommodate the sports car underpinnings.
The white Qashqai-R seen above will be tuned to produce 900 horsepower, while a black version will get bumped up to 1,000 hp. And, looking at the build photos, we surmise that this project will take nothing less than a herculean feat of supercar determination before it's through.

Renault names new leaders as jailed Carlos Ghosn bows out

PARIS — Renault appointed Michelin boss Jean-Dominique Senard as its new chairman on Thursday, after Carlos Ghosn was forced to resign in the wake of a financial scandal that has rocked the French carmaker and its alliance with Japan's Nissan. Senard will become chairman immediately, the company said, with deputy chief executive Thierry Bollore taking over Ghosn's other Renault role as full CEO. The appointments may begin to ease a Renault-Nissan leadership crisis that erupted after Ghosn's Nov. 19 arrest in Japan and swift dismissal as Nissan chairman. Senard, 65, now faces the task of soothing relations with Renault's Japanese partner and resuming talks on a new alliance structure to cement the 20-year-old partnership. "It's important that this alliance remain extremely strong," Senard told reporters after a board meeting - citing the mounting investment demands of new vehicle technologies. "It is our compulsory duty to go forward together." Ghosn's exit also marks a clear end to one of the auto industry's most feted careers, two decades after he was despatched by former Renault boss Louis Schweitzer to rescue newly acquired Nissan from near-bankruptcy — a feat he pulled off in two years. After 14 years as Renault CEO and a decade as chairman, Ghosn formally resigned from both roles on the eve of the board meeting. Ghosn's arrest and indictment for financial misconduct has strained the Renault-Nissan relationship, threatening the future of the industrial partnership he transformed into a global carmaking giant over two decades. For two months, the tensions deepened as Renault and the French government stuck by Ghosn despite the revelation he had arranged to be paid tens of millions of dollars in additional income, unbeknownst to shareholders. Ghosn has been charged with failing to disclose more than $80 million in additional compensation for 2010-18 that he had agreed to be paid later. Nissan director Greg Kelly and the Japanese company itself have also been indicted. Both men deny the deferred pay was illegal or required disclosure, while not contesting the agreements' existence. Ghosn has denied a separate breach of trust charge over personal investment losses he temporarily transferred to Nissan in 2008. Ghosn had agreed in recent days to step down from Renault, Reuters reported on Tuesday — but only after the French government, Renault's biggest shareholder, called for leadership change and his bail requests were rejected.
