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.

Nissan union wants French to stop meddling with Renault alliance

Nissan is getting some unexpected reinforcements in its ongoing battle with the French government over its involvement in Renault. Its Japanese union, which has traditionally been a very hands-off entity, issued harsh criticism for the French government's attempts to assert control over its alliance partner. According to Bloomberg, this is the first time in 16 years that Nissan's union has weighed on the company's affairs, and it's stating its position on the matter in no uncertain terms. The union called France's attempt at scoring double voting rights within Renault "unacceptable and against the intended spirit of the Alliance." "We support the numerous attempts of Nissan to engage with the French government to find a balanced and constructive solution that will benefit and strengthen the Alliance," the union said in a statement obtained by Reuters. It's unclear what impact the union speaking out will have on the current power struggle between Renault-Nissan CEO Carlos Ghosn (shown above) and the French government, but we doubt it'll contribute to any quicker of a conclusion.

Nissan's current Rogue renamed Rogue Select, will live alongside next gen

Despite the fact that an all-new generation of its Rogue crossover goes on sale in November, Nissan will continue to sell the current model alongside its replacement. The existing C-platform-based Rogue, which will be renamed Rogue Select, will start at less than $20,000 when it goes on sale in January 2014. At present, a base 2013 Rogue S prices out slightly higher, from $20,310, but we wouldn't be surprised to see the 2014 Rogue Select come to market with more standard equipment and simplified trim options. It will continue to be built in Kyushu, Japan.
According to Nissan, the unusual move is "to satisfy demand for the popular compact sports utility vehicle, currently second-highest seller in Nissan's lineup, as well as provide customers an additional choice in the segment." It's hard to hard to argue with the numbers: Nissan cites 2012 calendar-year sales of 142,349 Rogue units in the US, with 2013 sales increasing 16 percent through August despite the vehicle's age.
The strategy may also give Nissan the chance to ask for more money for the second-generation model (which is based on a new Common Module Family platform shared with partner Renault) while keeping it clear of residual-value-damaging fleet sales. The new Rogue looks to be both larger and more luxurious, with an available third-row seat, and it should be more economical to produce, as it will be built in Nissan's Smyrna, TN plant.
