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.

Carlos Ghosn takes a walk in a park, as lawyer apologizes for disguise

TOKYO — Former Nissan chairman Carlos Ghosn was seen walking in a Tokyo park on Friday, two days after his release in a strange disguise from a Japanese detention center. Ghosn, this time in sunglasses and a Stanford baseball cap (his daughter Caroline's alma mater), was spotted outdoors twice on Friday, strolling outside in the crisp March air. He and several others, believed to be his wife and daughters, visited a downtown Tokyo garden as members of the media trailed them and watched. The intense media attention was what led Ghosn's lawyers to suggest he leave the Tokyo Detention Center after his release on bail Wednesday in a laborer's outfit of cap, surgical mask and high-visibility vest, attorney Takashi Takano said. Many were baffled by the somewhat transparent disguise, which has riveted Japanese tabloid media. One TV show re-enacted his departure. Takano said in a blog post that he took full responsibility for what he called the "theater of disguise." He apologized for its failure. The outfit was confusing but didn't deter media from tracking the small van he traveled in after his release, in a spectacle broadcast live on television. "My immature plan, as a result, has tarnished the reputation that he has devoted his whole life to build," Takano said of his client. Takano asked the media to respect Ghosn's privacy. That plea appeared to go unheeded as cameramen closely followed the celebrity executive as those walking with him stared straight ahead in apparent annoyance. Ghosn, who headed the Renault-Nissan-Mitsubishi Motors alliance, has been charged with falsifying financial reports, under-reporting his income and breach of trust in having Nissan Motor Co. shoulder personal investment losses and make payments to a Saudi businessman. He says he is innocent and that the income allegedly under-reported was never paid or decided, that Nissan never suffered the investment losses and the payments were for legitimate services. In Japan, suspects are routinely kept in detention until preparations for their trials are ready, meaning they are often detained for months. The court rejected two earlier requests by Ghosn for bail. Ghosn led Nissan for two decades, saving the Yokohama-based automaker from near bankruptcy. He was arrested on Nov. 19.

Renault-Nissan-Mitsubishi pool $200 million to invest in tech startups

PARIS — The Renault-Nissan-Mitsubishi alliance is setting up a $200 million mobility tech fund, three sources said, in the latest move by major carmakers to adapt to rapid industry change by investing in startups through their own venture capital arms. The fund, due to be unveiled by Chief Executive Carlos Ghosn at the CES tech industry show in Las Vegas next Tuesday, will be 40 percent financed by Renault, 40 percent by Nissan and 20 percent by Mitsubishi. "It will allow us to move faster on acquisitions ahead of our competition," one of the alliance sources told Reuters. Frederique Le Greves, a spokeswoman for the Renault-Nissan-Mitsubishi alliance, declined to comment. The traditional auto industry model based on individual ownership is threatened by pay-per-use services such as Uber, as well as ride- and car-sharing platforms, a challenge heightened by parallel shifts towards electrified and self-driving cars. Wary carmakers are struggling to embrace changes and technologies that some of their executives are only beginning to grasp. To accelerate the process, many are investing directly in the new services — and gaining access to intellectual property — via their own corporate venture capital (CVC) funds. BMW has purchased stakes in a plethora of ride-sharing, smart-charging and autonomous vehicle software firms through its 500 million euro ($600 million) iVentures fund, the biggest such in-house facility belonging to a carmaker. Among others that have been increasingly active are General Motors' GM Ventures, with $240 million, and Peugeot-maker PSA Group's 100 million-euro investment arm. CVC funds, a familiar feature of innovative sectors such as tech and pharmaceuticals, have become more commonplace among carmakers since the 2008-9 financial crisis. They let companies skip some of the formalities otherwise required for new investments, and pounce more swiftly on promising startups. The Renault-Nissan-Mitsubishi venture will also obviate the current need to thrash out the ownership split for each new alliance acquisition. It represents a further step in the integration of the carmakers as they pursue 10 billion euros in annual synergies by 2022. France's Renault holds a 43.4 percent stake in Nissan, which in turn controls Mitsubishi. Ghosn heads Renault and chairs all three.
