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 plans to have 1,700 CHAdeMO chargers by April, 2016

Grab a bite, charge your Leaf. That's sort of the premise behind quick chargers that provide about 80 percent of single-charge driving range in about a half hour of charging. And Nissan says it's doing its part to expand the number of those stations to please its growing list of constituents. The first 160 quick chargers using the CHAdeMO standard were installed in the US three years ago and that number totals about 800 today. About 300 more will be added by April 1, and by April 1, 2016, the number of quick chargers could reach about 1,700. Atlanta, Dallas, Los Angeles and San Francisco are among the cities leading the way in quick-charger availability. The Japanese automaker, which started selling the Leaf in the US in late 2010, is doing other things to make it easier for Leaf owners to recharge, whether through quick chargers or standard ones. Last summer, Nissan launched its "No Charge to Charge" program that gives new Leaf buyers free charging at participating public charging stations for two years. A 34-percent jump in Leaf sales, which is what Nissan recorded in the US last year, will do that to a company. For some more specifics of the quick charging contingent, take a look at Nissan's press release below. Fact Sheet: Nissan's commitment to EV quick charging for LEAF drivers Since the launch of the Nissan LEAF in late 2010, Nissan has reinforced its commitment to zero emission mobility with investments in EV charging infrastructure to serve the needs of LEAF drivers in markets across the U.S. Nissan has a multi-pronged strategy to invest with charging partners to install quick charging for owners in the communities where they live and work, as well as at corporate workplaces and Nissan dealerships. Timeline of (CHAdeMO) quick charging rollout: - January 2013: Approximately 160 CHAdeMO chargers installed nationwide. - January 2015: More than 800 total U.S. quick chargers installed and active. - April 1, 2015: 1,100 quick chargers expected nationwide. - April 1, 2016: 1,700 quick chargers projected. "Access to quick chargers that can provide about 80 percent charge to a Nissan LEAF battery in less than 30 minutes has proved to increase our owner satisfaction and get more buyers to consider the benefits of an all-electric car," said Brendan Jones, Nissan's director of Electric Vehicle Sales and Infrastructure Deployment.

Deltawing takes out second ad targeting Nissan amidst design lawsuit

Don Panoz isn't a guy shy away from a fight. Since December, Panoz's Deltawing Technologies has been in a lawsuit with Nissan over alleged intellectual property violations with the design of the Zeod RC. The situation went public several weeks ago when Deltawing bought an ad in The Tennessean, a paper near Nissan's US headquarters, and the industry trade, Automotive News, aimed squarely at company CEO Carlos Ghosn.
Now, Deltawing is trying the tactic a second time with an even more scathing ad in The Tennessean on July 11 and in Automotive News on July 14 that calls the Zeod's design out directly. The bulletin puts the two racecars side by side and asks readers compare their similarities.
According to Deltawing spokesperson Gary Fong, the idea for these ads started after mediation between the company and Nissan broke down earlier this year. "We were trying to bring them to settle it amicably," he said to Autoblog. When that didn't happen, Deltawing wanted to fight the misconceptions in the public about the program and lawsuit. The strategy actually worked, too. "We've seen an opinion change," said Fong. He estimates that before the advertisements the attitude was "90 percent against Panoz," but there has been more support since them.
