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.

2014 Nissan Versa Note

Incredible Value Has Trouble Winning Hearts
How important is vehicle sticker price? How imperative is fuel economy? What about passenger room and technology?
Nissan is hoping that consumers find all four objective measurements significant, because the all-new 2014 Versa Note excels in each of those areas. Not only does the five-door deliver the most competitive pricing, but it provides best-in-class combined fuel economy and best-in-class total interior volume. And the new model offers a full range of innovative technology, including available navigation and the automaker's impressive Around-View monitor to ease parking.

Nissan planning 90-second Super Bowl commercial, plus two debut cameos

The Super Bowl is still a few days away, but the big ads from several automakers for the game are already streaming online. Nissan is bucking the trend, though, and the Japanese brand is only releasing the first 10 seconds of its spot before the actual premiere. Much like one of Toyota's ads, Nissan is choosing to focus on fathers this year. The story of the commercial is about a racecar-driving dad balancing work and life with his new child, but despite the motorsports connection, the teaser shows cars for just a few seconds. Hopefully, setting the commercial to Harry Chapin's Cat's in the Cradle doesn't make the whole thing too maudlin. We'll be seeing even more from Nissan during the Super Bowl than originally thought, as well. The automaker will now be taking 90 seconds of ad time during the game, rather than the original plan for 60 seconds. Perhaps the extension will give the company even more time to show off its two surprise product cameos during the spot. One of them is rumored to be the first official glimpse at the GT-R LM Nismo LMP1 racer. Nissan lengthens Super Bowl commercial to 90 seconds, teases "With Dad" spot with release of brief clip Nissan back as Super Bowl advertiser after nearly two decades Releases first 10 seconds of its ad as a teaser Announces the in-game commercial has been lengthened to 90 seconds Story will depict the struggle of work-life balance facing many American families Iconic song "Cats in the Cradle" by the late Harry Chapin featured Two surprise products to make cameo appearances NASHVILLE, Tenn. – Nissan, which has been teasing its Super Bowl plans through a one-of-a-kind social media campaign using YouTube "content creator" videos and the hashtag #withdad, is giving the first hint of its in-game commercial by releasing a short preview of the spot today. Nissan previously announced it would feature a 60-second spot in the Super Bowl. The company has increased its stake in the game to a 90-second ad, which it says will tell a unique family story while maintaining a strong Nissan brand connection.
