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.

YouTuber TJ Smith is your singing Lyft driver in Nissan Sentra ad

Perhaps you've seen Nissan's latest commercial, promoting the Sentra. It's a fairly simple little spot, showing the compact's driver blaring Billy Idol's Mony Mony, singing along and encouraging other motorists to join in.
We'd have been fine had it been left at that. It's a simple commercial that shows the car with a catchy tune and smiling people. Nissan couldn't leave well enough alone, though, and has come back with this. Starring TJ Smith - the driver from the original ad and an apparent YouTube celebrity famous for the kind of thing shown in the original commercial - the new ad expands on the old, with more people, and more Mony Mony. This time round, Smith is serving as a driver for the Lyft service, who just happens to break into song with his fares in the car.
Scroll down for the full video. If you've no idea what we're talking about, we've also included the original commercial.

Carlos Ghosn returns as president of ACEA

The European Automobile Manufacturers' Association (abbreviated ACEA in French) is an industry group representing all the biggest automakers in Europe, representing their common interests on the world stage. And as such it needs a leader, figurehead and mouthpiece to serve as its president, and for the second time the association's board of directors has chosen Carlos Ghosn.
Now if you're recognizing Ghosn as the CEO of Nissan and wondering what that has to do with European cars, it's not because Nissan manufactures much in Europe. In fact, it only operates has a handful of locations in Europe: one in the UK, one in Barcelona and one in St Petersburg. But you'd be wise to recall that Ghosn also serves as CEO of Renault, one of the biggest players in European automobile manufacturing. He also sits on the boards at Russian automaker AvtoVAZ (of which Renault owns 25 percent) and of his native Brazil's Banco Itaú, not to mention the advisory councils of a handful of universities - two of them from his ancestral hometown of Beirut. He previously served as president of ACEA in 2009, and was re-elected to replace outgoing PSA chairman Philippe Varin.
Alongside Renault, ACEA membership includes BMW, Daimler, Fiat, Jaguar Land Rover, PSA Peugeot Citroën, Volkswagen and Volvo, along with the European divisions of Ford, General Motors, Hyundai and Toyota, as well as a handful of truck manufacturers.
