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 confirms new "premium compact" to be built in UK

Aside from certain naming-related news, Infiniti has actually had some decent product news to announce this week. The company's president, Johan de Nysschen, alluded to a new 550-horsepower performance sedan, and now the automaker has confirmed that a new "premium compact" will go into production in 2015. Based on the fact that this new model will be built alongside the Nissan Leaf at the automaker's Sunderland, UK assembly plant, we could only hope that it's a production version of the LE Concept (shown above).
Sunderland already produces Nissan products like the Qashqai, Juke and Note, and as a part of an investment of 250 million British pounds (around $406 million USD) for the new model, the plant would add an extra 280 jobs with the capacity to build 60,000 of the new Infinitis annually. Adding the premium compact at Sunderland means that Infiniti will have to change its plans for another new model, a bigger "C-segment hatchback," which could very well be a production version of the Etherea Concept.

2014 Infiniti Q50

Avoiding An Identity Crisis... For Now
Infiniti is a brand that has been quietly undergoing major upheaval - and not just with the numbers and letters on its trunklids. Back in December, Nissan's premium brand rankled fans and pundits by announcing it would redo its alphanumeric nomenclature, yet that decision was but a PR speedbump - there are bigger fish to fry. After all, this is a marque that was on the chopping block just a couple of years ago, and now it has a major opportunity to succeed thanks to new investment, new independence (Infiniti is now responsible for its own design, engineering, marketing, quality and human resources), a new global headquarters in Hong Kong, and new marching orders from new leadership that calls for a revitalized and expanded portfolio.
Yet if you think that the Q-based naming convention is the first sign of the brand's new direction, you might have missed Infiniti's biggest signal flare: the 2013 JX crossover. Fine premium three-row crossover that it may be, it's still the first Infiniti in ages that operates without a scintilla of driving entertainment at the core of its genetic makeup. (The last - and perhaps only - previous example was also Pathfinder-based, the 1997 QX4). To be fair, three-row CUVs have a laundry list of priorities before driving enjoyment figures in, but the message the JX (henceforth known as the QX60) sends is clear: Infiniti is going after more segments and more customers. Plans are afoot to expand the company's product line by a whopping 60 percent over the next five years, and in short, that means Infiniti is no longer content to be the unsung Japanese BMW - it needs vehicles that satisfy a wider swath of consumers. Despite all this, Infiniti officials we spoke with were keen to assert that driving pleasure remains very much core to their mission, and to that of this 2014 Q50 in particular.
