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.

Spitballs flying between Nissan and Fiat

At the 2012 LA Auto Show, Fiat brand chief and recently crowned marketing genius, Olivier François, attempted to distance the Fiat 500e from other electric vehicles, asking rhetorically, "Isn't ugliness the worst kind of pollution?" Nissan has apparently taken issue with these comments, feeling slighted for what it considers digs at the Leaf's styling. In a recent interview with Automotive News, Nissan's marketing chief Simon Sproule shot back, "Let's face it, Fiat has not shied away from controversial styling themselves," he continued, "many would describe many of their products as visual pollution." Ouch.
Sproule says that while the 500e is a "me-too" product, made only to appease US emissions regulations, the Leaf is a serious effort at producing an EV. The Nissan marketing boss points out that the Japanese automaker has invested billions in EV development and production facilities, while Fiat will lose $10,000 on every 500e sold.
However sales of the Leaf in the US are down five percent. Nissan sold just 8,330 Leaf's so far this year, but Sproule contends that it has less to do with styling, and more with the charging infrastructure. Sproule also thinks that Nissan hit a balance between styling and practicality with the Leaf: "It's still very recognizable as a five-seat hatchback, fully functioning, absolutely competitive with the packaging of the Golf of any other mainstream vehicle." For a segment where efficiency is king, isn't that what matters most?

Nissan Patrol attempts Guinness record with 170-ton cargo plane tow

Yesterday, Nissan teased us with a video showing a Patrol pulling up to a 170-ton cargo plane at an airport in the Middle East - we could only assume that the not-for-America sports utility vehicle would attempt to tow the jet.
Well, somebody leaked the official Nissan video, which indeed shows the Patrol successfully pulling the plane 30 meters for what reportedly is a Guinness world record. While Guinness hasn't confirmed the record on its website at time of writing, the 170-ton jet would be the heaviest plane ever towed by a production automobile. The video was taken down quickly, but another video shot by an observer at the event was posted for our enjoyment. We figured Nissan would move to repost the official video sooner rather than later, and it did.
The Patrol seems to have no problem towing 340,000 pounds, but let's just say it wasn't a quick ordeal. Check out the official and unofficial video of the tow below, as well as Nissan's teaser video. In a reversal of fortunes, we also threw in another, somewhat smaller but perhaps just as impressive vid, just for fun.
