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.

Nissan working on bringing bizarro BladeGlider to dealerships?

It's a rare thing for pie-in-the-sky concepts to make production relatively unmolested. Edges are usually softened, mirrors made bigger and wheels shrunken into something that will be less backbreaking and easier to see out of on public roads. And while the essence of many concepts can still find their way into production, the wackier parts found in their concept forms often end up as nothing more than flights of fancy.
That makes news of the strange Nissan BladeGlider being considered for production rather interesting. You'll recall that the BladeGlider Concept debuted in November at the 2013 Tokyo Motor Show, featuring a McLaren-esque three-seat V layout, an electric drivetrain and a narrow front track like the DeltaWing and ZEOD RC. Understandably, perhaps, Nissan has been touting it as "reinventing the performance car." Everything about it screamed "concept."
Now comes word from Car in the UK that the car may actually make it to production. Quoting Nissan vice president Andy Palmer, "It's in our mid-term plan." "Our intention is to do it," he says. Now, Palmer has plenty of sway, but this should hardly be taken as an absolute confirmation that the triangle-shaped car would be coming. It is, however, a very promising sign. Palmer evidently sees the BladeGlider as a way to cajole young people into becoming car enthusiasts, which suggests Nissan might try to make it inexpensive. Alternatively, the BladeGlider could form the basis of a small-volume racecar, but it isn't clear what racing organization would have it.
