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's dismal 2019: Where does Japan's struggling brand go from here?

Auto sales have gradually slowed from their peak during the boom years that followed the global recession, but Nissan's rapid decline stood out even in a year when few high-volume manufacturers had much to be excited about.  Of the "Japanese 3," Nissan's 2019 performance was by far the most troubling. Through November, when the company last posted its global sales figures, its volumes were down 8 percent compared to 2019. Here in the United States, its full-year numbers were down 9.9% in an industry that slid just a hair more than 2 percent overall.  Meanwhile, Honda managed a slight increase in U.S. sales (0.2%) and Toyota, much like the industry in general, finished the year down approximately 2%. Like Nissan, Honda and Toyota have remained committed to cars — including compact and midsize sedans — and have a comprehensive portfolio of offerings in the key SUV and crossover segments.   On paper, Nissan's lineup checks all the right boxes. From the subcompact Kicks up to the Armada, it has something for sale in virtually every possible nook and cranny of the people-mover segment, but almost all of these trucks (and trucklets) took a beating in 2019. Only the baby Kicks managed to improve on its 2018 sales, which isn't saying a whole lot, considering it was barely sold in 2018 to begin with.  In fact, the bonus volume contributed by Kicks helps obscure just how poorly some of Nissan's key offerings performed last year. Combined Rogue and Rogue Sport sales slid 15%; Murano was down more than 18%; the Pathfinder and Armada managed to pace the general industry, dropping 2.8 and 1.9%, respectively, but the astute reader will note at this point that we've yet to single out any bright spots. The news was even worse on the truck side. Frontier was down 9.1%. Titan? Down 37.5%. Crossovers and SUVs are selling. Trucks, even from import brands, are also selling. Toyota's mid-size Tacoma was up in 2019; both it and the full-size Tundra still more than tripled the volume of their Nissan competitors. Further muddying the waters, Honda managed its year-over-year volume increase without selling a full-sized pickup at all.  What, then, is Nissan's problem? To borrow an oft-used phrase, "It's the product, stupid." The most striking evidence of this issue is the Rogue, which competes in the compact crossover segment — a collection of vehicles that essentially sell themselves.

Carlos Ghosn video: 'This is about conspiracy. This is about backstabbing'

TOKYO — Nissan's former Chairman Carlos Ghosn maintained his innocence in a video released by his legal team Tuesday and accused some executives at the Japanese automaker of a "conspiracy" that led to his arrest on financial misconduct allegations. "The first message is that I'm innocent," said Ghosn, wearing a white shirt and dark jacket and speaking calmly in the nearly 10-minute video shown at the Foreign Correspondents' Club in Tokyo. "This is a conspiracy," he said. "This is not about specific events, this is not about, again, greed, this is not about dictatorship. This is about a plot. This is about conspiracy. This is about backstabbing." His lawyer Junichiro Hironaka said the video was prepared in case Ghosn was not able to speak at a news conference planned for Thursday. Ghosn was arrested last week while out on bail and remains at the Tokyo Detention Center. Ghosn said the executives behind the conspiracy were motivated by what he called "selfish fears," including what they saw as a merger with French alliance partner Renault SA. They mistook his leadership for greed and dictatorship, when he was the biggest defender of Nissan's autonomy, Ghosn said. He also said he was worried about Nissan, wondering whether those executives were really watching out for the company. Hironaka said a section of the video in which Ghosn mentioned names was removed on his legal advice. Nissan Motor Co., while declining to comment on the criminal case, has said an internal investigation has found that Ghosn falsified financial documents to under-report compensation, and that he used Nissan money for personal gain. "Nissan's internal investigation has uncovered substantial evidence of blatantly unethical conduct," company spokesman Nicholas Maxfield said when asked for comment on Ghosn's video. "The company's focus remains on addressing weaknesses in governance that enabled this misconduct." Ghosn's fourth arrest was on a fresh breach of trust allegation based on suspicion that payments from a Nissan subsidiary to an Oman dealership were diverted to a company effectively run by Ghosn. On Monday, Nissan Motor Co. shareholders voted to oust Ghosn from its board and to approve the appointment of French alliance partner Renault SA's Chairman Jean-Dominique Senard as Ghosn's replacement. Renault owns 43 percent of Nissan.
