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 hopes to inject some spice into Rogue with 'Open The Briefcase'

Nissan is in the midst of rolling out the redesigned 2014 Rogue and has launched an interesting social media game called Open The Briefcase. The video that launches this game depicts a simple ride-share gone very wrong, with a man getting embroiled in a high-speed chase in a bid to escape with a strange briefcase. Eventually, it all goes haywire, and the man and his driver are captured. The only question seems to be, what's in the briefcase?
The contest, which asks participants to select one of three briefcases by cracking a code, is set to reward three individuals with a new Rogue. New attempts can be made each day, and participants can get additional chances to open a briefcase by sharing the video. The contest kicked off on January 3 and will run until February 14. Hop over to the contest page on Facebook to take part, or just watch the video below and enjoy a bit of entertainment.

Nissan reportedly rejecting Renault proposal for closer ties

TOKYO — Nissan Motor Co Ltd will reject a management integration proposal from French partner Renault SA and will call for an equal capital relationship, the Nikkei newspaper said on Monday, citing sources. Nissan's management feels the Japanese company has not been treated as an equal of Renault under existing capital ties, and a merger would make this inequality permanent, the Nikkei reported. The outlook for the alliance — one of the world's top automaking partnerships — has been in focus since the arrest in November of its main architect, Carlos Ghosn, on charges of financial misconduct. The former Nissan and Renault chairman has denied the charges against him and has said he was the victim of a boardroom coup by Nissan executives opposed to closer ties. To which, Bloomberg reported that it has seen emails in which Nissan executives were working with Japanese government officials to defend the company's independence, as Ghosn was pushing for a full merger. The emails indicate growing concern at high levels of the Japanese government, in the months before Ghosn's arrest, that his merger efforts would boost Renault and its largest shareholder, the French government, and harm Nissan, in a relationship the Japanese already saw as lopsided. The emails indicated a desire to keep the existing structure of the alliance with a "re-balancing of the shareholding" to reduce Renault's 43 percent stake in Nissan, and stated that Nissan's independence "should be respected." Nissan declined to comment directly on the emails, while reiterating that misconduct by Ghosn and his former aide, Greg Kelly, is "the sole cause of the chain of events." Renault saved Nissan from the brink of bankruptcy two decades ago and under their current capital alliance, the French company holds greater control over its much larger partner. Nissan Chief Executive Hiroto Saikawa declined to say whether the company had received a merger proposal from Renault. "Now is not the time to think of such things," he told a group of reporters outside of his house in Tokyo. "At the moment we are focused on improving Nissan's earnings performance. Please give us time to do that." Renault declined to comment on the report. Renault has argued in its proposal that an integration would maximize synergies within the French-Japanese alliance, according to the Nikkei. The Financial Times reported last month of Renault's intention to restart merger talks with Nissan within 12 months.
