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.

In his own words: Carlos Ghosn on why EVs rule

That's a nice little dig at hydrogen fuel cell technology, Mr. Ghosn. The Nissan chief, long a champion and heavy-duty investor of electric-vehicle technology, wrote an essay on his LinkedIn Influencer page on why EVs are the theoretical wave of the future. It's obviously not an unbiased opinion, but he makes his points clearly. Ghosn points out that "refueling" costs per mile for EVs are about 70 percent less than gasoline and more than 60 percent less than hybrids. He cites the rapidly growing network of plug-in vehicle charging stations that are eliminating "range anxiety" with at least some folks, and notes that the fastest growing US plug-in vehicle market is, of all places, Atlanta. Additionally, Ghosn, near the bottom of the post, says that a plug-in vehicle charging station can be deployed for as little as $2,000, while building a hydrogen station costs about $2.5 million. Pretty clever. Nissan's sales numbers appear to give Ghosn's confidence some clout. Through November, sales of the Leaf in the US surged 35 percent from a year earlier to more than 27,000 units. Globally, Nissan says the Leaf's sales are up 20 percent this year. Check out Ghosn's own words below. Zero-Emission Cars: Both Consumers and the Environment Win Last month, the Renault-Nissan Alliance sold its 200,000th zero-emission car. The Nissan LEAF, which we launched four years ago, is by far the top-selling electric vehicle worldwide. Sales are up 20 percent this year. Together with the Renault ZOE and other zero-emission vehicles in our lineup, Renault-Nissan's EVs have been driven about 4 billion kilometers – enough to circle the earth 100,000 times. They are the world's first and most successful mainstream, mass-marketed EVs. Why are more people switching to EVs? The reasons are clear: EVs are convenient: They can be refueled at home or at the office from multiple energy sources, including the increasing amount of clean energy from solar or wind power. Imagine never stopping at a gasoline service station because you wake up to a "full tank" every day. This is one of the top things EV owners enjoy about their cars. EVs are economical: Even with gasoline prices falling, Consumer Reports recently estimated operating costs of a Nissan LEAF in the United States at 3.5 cents a mile, compared with 11.9 cents for a subcompact gasoline car or 8.6 cents for a hybrid. EV owners typically save on their insurance policies, because insurers view EV drivers as a lower risk.
