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 boss De Nysschen confirms next-gen Q60 Coupe, ponders high-performance variants

We've known since mid-December that Infiniti's new global model naming convention would turn the current-generation G37 Coupe into the Q60 Coupe starting next year, but we haven't been clear on whether the model-range-formerly-known-as-G would get a successor, especially as its volume has traditionally been a lot lower than its sedan counterpart.
Thankfully, Infiniti president Johann De Nysschen (above) has stepped up to confirm that the newly revealed Q50 sedan will receive a two-door counterpart, though perhaps not as quickly as some would like. According to an interview with Australia's CarAdvice.com, De Nysschen says "the coupe we can probably expect two-and-a-half to three years down the road." That news also suggests that if there's an eventual convertible version, that it's a long way off, too. Why so long? Infiniti has "a lot of priorities" - priorities that undoubtedly include an already-confirmed front-wheel-drive small hatchback/crossover.
The report also indicates that Infiniti has some aspirations for stretching its new Q50/Q60 range in a higher-performance direction to take on competitors like BMW and Audi, the latter being De Nysschen's former employer. There's far from a firm timetable offered, of course, with De Nysschen saying "someday in the future we will be able to offer more high performance versions [of Q50] than we have today... the dynamic capabilities of this platform are very significant. It can handle far higher power than the engines we are using at launch."

Infiniti's Palmer announces QX30 small crossover production

The name of the game these days in the luxury marketplace is premium compacts. BMW has the 1 Series and 2 Series, Mercedes the A-Class, B-Class, CLA and GLA, Audi has the A1 and A3, even Lexus has the CT 200h. Among the last to get in on the action is Infiniti, but that's all about to change.
Nissan's luxury brand has been working towards a premium compact for some time, revealing the Q30 concept at the Frankfurt Motor Show last year and signing a new deal with Daimler to help develop and produce it. Now it seems that both it and a crossover version have been approved for production.
The news comes from Andy Palmer, Nissan's UK-based COO, chairman of Infiniti and one of the company's top executives under CEO Carlos Ghosn. Late last week Palmer tweeted the following:
