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.

Infiniti aims to "de-Americanize" lineup, add flagship

Nissan launched Infiniti back in 1989 as a US brand, but more recently, Nissan's luxury marque has started focusing on more of a global presence. With a new global headquarters set up in Hong Kong and former Audi bigwig Johan de Nysschen at the helm, Wards Auto is reporting that the automaker's next goal is to create a "de-Americanized" lineup of vehicles.
This plan essentially consists of smaller cars and smaller-displacement engines to make Infiniti more attractive for buyers in Europe and Asia - two regions that tend to skew more toward smaller vehicles and smaller powerplants. To this point, Infiniti has been focused on vehicles better-suited to the US market - in fact, its smallest engine is a 3.7-liter V6 with 330 horsepower, and it doesn't offer a single diesel.
The first step in this transformation will be part of the Daimler-Nissan engine deal that will see a four-cylinder diesel eventually used in the 2014 Q50, but the report also reconfirms the importance of the soon-to-arrive Q30 production model (a concept of which was revealed last week in Frankfurt), along with the idea of a QX30 based on the Nissan Qashqai. There's also the latest projection of a full-electric Infiniti model that Wards says will debut sometime around 2015. Of course, Infiniti isn't giving up on large cars entirely - the reports indicates that Infiniti is planning a fullsize flagship model - possibly named Q80 - to compete against German sedans like the Audi A8, BMW 7 Series and Mercedes-Benz S-Class.

Nissan and Infiniti to get 6 EVs within 5 years

Nissan will get four new electric-powered vehicles, while its luxury division Infiniti will get two over the next five years, a top executive told Automotive News. The six EVs will make up Nissan and Infiniti's share of the 12 electric vehicles planned for Renault-Nissan-Mitsubishi by 2022, though there's no word on how the numbers break down for those other brands. Infiniti last month announced plans for its first all-electric vehicle in 2021, plus new "e-Power" series hybrids like the ones it has introduced in other markets. But the six vehicles divulged by Toshihiro Hirai, Nissan's corporate vice president for powertrain and EV engineering, reportedly include only full battery-electrics and not hybrids. The only full-electric currently offered by either brand in the U.S. is the Nissan Leaf, which was just updated for 2018. Nissan-Renault CEO Carlos Ghosn has been a consistent supporter of electric vehicles, and he has said EVs need greater government incentives, lower development costs and a greater recognition among the buying public of the risks of climate change in order to gain traction among consumers. Last summer, Nissan-Renault announced plans to build electric vehicles in China in a new venture with Dongfeng Motor to meet EV quotas. They'll use a subcompact crossover platform from its own vehicle family.Related Video:
