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.

Renault ousts CEO days after Nissan gets a new one

Newly-appointed interim CEO Clotilde Delbos and Chairman of Renault SA Jean-Dominique Senard. / Reuters   PARIS — Renault ousted chief executive Thierry Bollore on Friday, as the French carmaker and its Japanese partner Nissan seek to rekindle their alliance following the scandal-hit tenure of former alliance supremo Carlos Ghosn. Tensions between Renault and Nissan, which picked a new CEO on Tuesday, have been high since Ghosn's arrest in Tokyo last year on allegations of financial misconduct, which he denies. Bollore, who was close to Ghosn and had strained relations with Nissan's previous boss, will be replaced on an interim basis by Renault finance director Clotilde Delbos. With new faces at the helm, Renault chairman Jean-Dominique Senard is hoping to draw a line under almost a year of turmoil and revive cooperation between two carmakers once seen as destined to fully merge. That is vital at a time when auto markets are slowing and carmakers are having to invest in costly new technologies as well as meet challenging European emissions regulations. "We're at a new stage now for this alliance. Sometimes you need new management ... to breathe new life into things," Senard, who was brought in earlier this year from tyre maker Michelin, told a news conference in Paris. He said three members of Renault's 18-strong board abstained in the vote to remove Bollore, who hit out at his looming dismissal in a newspaper interview the night before, calling it a coup. Following Ghosn's arrest, a feeling of stagnation around joint Renault-Nissan projects, including on issues such as advancing on cost savings, had begun to set in, people at Renault have said. These would now be the first priority, according to a source close to the carmaker. "There are a lot of concrete matters that have already been identified, including on the industrial front: working on batteries, electric vehicles, connectivity, purchasing and self-driving cars," the source said. Shares in Renault closed up 5.1%. 'Coup de force' Tensions between Renault and Nissan were further inflamed this year, including during various spats over governance reforms, and after a failed deal to pair Renault up with Fiat Chrysler, which withdrew a merger offer. Senard reiterated on Friday that a tie-up with Fiat, which was abandoned in June, was not at present on the agenda.

Nissan's 'No Charge to Charge' is what incentives look like in the EV age [UPDATE]

Nissan knows that offering free charging can increase Leaf sales, so it only makes sense for them to expand the "No Charge to Charge" program. And that's exactly what happened yesterday. As previewed during the New York Auto Show, No Charge To Charge gives new Leaf buyers free charging at participating public charging stations – which is pretty much any public station – for two years. That's the kind of thing that simplifies the EV buying process, which can move units, Brendan Jones, director of Nissan EV sales and infrastructure, told AutoblogGreen. "There is an expectation that we'll get a sales increase out of this," Jones said. "All the dealer has to say is that we have one card that accesses all chargers and we have a promotion where you can get free charging. The more complexity we reduce, the more sales we get." "The more complexity we reduce, the more sales we get." – Nissan's Brendan Jones That all-access angle is important for the broader EV market, Jones said, calling the program, "The first valid step towards interoperability." Jones said there will be more surprise announcements soon. "The infrastructure companies really came together to support Nissan on this," he said, but added that, "What's good for the industry and EVs in general is good for Nissan." "Leaf customers are not shy about their ability to provide constructive criticism," Jones said, " and interoperability has always been a big concern." Now that many of the early adopters drive an EV, the next target audience are the people who are telling EV companies to "Make this easy for me and I will adopt," Jones said. "[Interoperability] is a necessity for the industry now. We know the experience is great once they drive it. This just takes away a barrier, that confusion at the dealership." And, in some areas in the US, No Charge To Charge is now live. There are 2,600 public stations (200 of them fast chargers) in the initial 10 markets, Nissan says. Those include: San Francisco, Sacramento, San Diego, Seattle, Portland (OR), Nashville, Phoenix, Dallas-Fort Worth, Houston and Washington, DC. Nissan hasn't announced where the next 15 markets will be, but we know that they will likely be wherever the Leaf is selling well and there are a fair number of DC fast chargers. As we reported in April, each charging session in the No Charge To Charge program is limited to 30 minutes if you're plugged into a CHAdeMO fast charge station and to an hour at a Level 2 station.
