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.

Datsun to unveil second model later this month

Datsun, Nissan's new sub-brand for emerging markets, has announced plans to unveil its second model. Its first, the Go, was unveiled almost two months ago, and promised affordable, connected motoring for five in a handsome hatchback body. Datsun is following that up with a pair of new models for Indonesia.
The first of these two new vehicles will be shown on September 17 in Jakarta, eschewing the typical auto show debut. It's targeted at so-called "risers," the nickname for a group of highly aspirational customers in the Indonesian market. Datsun developed it locally with help from Nissan, and it'll cost under 100 million Indonesian rupiah (about $8,900 at today's rates).
We'll have the full boatload of information on the newest member of the Datsun family when it debuts on September 17. Scroll on to read the full press release from Datsun.

Nissan to expand next-gen Titan with more engines, configurations

Not much has changed with the Nissan Titan in the decade that it's been on the market, but the 2015 model year could move the needle enough to turn the truck from an "also ran" in the fullsize truck market to more of a contender. Edmunds had the chance to sit down with Pierre Loing, vice president of product and advanced planning and strategy for Nissan North America, who indicated that not only will a new truck be coming for 2015, it is also expected to take a bigger chunk of the truck market currently dominated by Ford and General Motors.
For starters, the article quotes Loing saying that the next-gen Titan could sell 100,000 units, which is almost five times the number of Titans and the same number of Toyota Tundra trucks sold last year. To accomplish this, Nissan is planning to offer a wider number of models (including a regular cab version) and more powertrain options; we're sure this means Nissan is considering offering a V6. The addition of a regular-cab, V6 Titan would also allow this truck to be more competitively priced.
Will that be enough to attract buyers away from the Big Three domestic trucks? We'll just have to wait and see...
