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.

China's largest dealer body pushes back against foreign automakers over huge inventories

Do not think for a second that automakers forcing inventory on dealers in order to pad the numbers is a ruse known only in the US. Stories of individual brands have hinted at the trouble Chinese dealerships are having trying to move units as the country's economic growth remains hot but comes off the boil, like the one revealing that 95 percent of Toyota-FAW showrooms are losing money. Yet Toyota isn't the only culprit, and the issue has become so dire that the China Automobile Dealers Association (CADA), the largest dealer body in the country, has written to the government to complain. Chinese car sales are expected to close out the year with an annualized growth of six-percent, down from last year's 14 percent when targets were set, while in the background the pace of overall economic expansion is the slowest its been since the early nineties. Automakers, shipping cars on schedule to make their earlier targets, have blown up inventories such that they are an average of 1.8 times monthly sales, when the preferred multiplier is from 0.9 to 1.2. According to the CADA, the price wars and necessary incentives mean that only 30 percent of dealers are operating in the black. That number is down a whopping forty percent since 2010. In response, Toyota has already said it will not make its 2014 target of 1.1 million cars sold. We're a long way from 2012, when Toyota planned on selling 1.8 million cars in China in 2015, a target that's now as realistic as a manticore. BMW, Honda and Nissan have erased numbers on their spreadsheets, too; BMW growth dropped from 20 percent to 8 percent midyear after it began "reducing wholesale supplies," and Honda has been reworking its plans as sales have decreased each of the past six months. It's a big deal for Chinese dealers to begin protesting publicly, the CADA saying, "In the past, dealers were angry, but dared not speak out. But now, they have to shout because the situation is getting so unbearable." With six-percent growth forecast for next year and dealers unwilling to remain underwater, The Year of the Sheep coming in 2015 could portend meaning beyond the zodiac.
