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.

European jury picks finalists for 2015 Car of the Year

There are countless Car of the Year awards handed out each year, and naturally, Europe has its own way of doing things. Every year, a panel of jurists representing seven publications in seven different languages and seven different countries get together to name their joint Car of the Year. The panel released a list of 32 candidates back in July, and it has now whittled that list down to seven nominees. The list consists of the BMW 2 Series Active Tourer, the Citroen C4 Cactus (shown), the Ford Mondeo, the Mercedes-Benz C-Class, the Nissan Qashqai, the Renault Twingo and the Volkswagen Passat. Of those seven, only two are available in the US – those being the Mondeo (sold Stateside as the Fusion) and the C-Class. The Passat is an entirely different model in North America, the Qashqai isn't offered here, Citroen and Renault don't even participate in our market and the BMW 2 Series is represented here only by the completely different coupe and convertible. Expect the one and only recipient of the 2015 Car of the Year award to be announced at the Geneva Motor Show this coming March, and while you're waiting, you can place your guesses for the eventual winner in Comments.

2015 Nissan Micra

Several years ago, poutine started showing up on the menus of a number of Detroit-area restaurants. For those unfamiliar with the Canadian specialty, it involves serving up french fries, gravy and cheese curds all in one artery-clogging heap. It's not really my thing, but the comfort-food dish has caught hold here in The D, and many absolutely swear by it. In a country where we happily serve Double Down sandwiches, and where competitive eating qualifies as sport, it's hard to believe le poutine isn't spreading like wildfire.
Given Detroit's proximity to Canada, it's not surprising that this culinary creation has managed to find its way across the border. The same thing goes for cars - we Detroiters are routinely privy to lots of Great White North imports. No, we can't buy not-for-US vehicles like the Nissan X-Trail, Mercedes-Benz B-Class (at least, the gasoline version), or now-discontinued products like the Honda Civic-based Acura CSX or EL before it. But Ontario-plated examples of these cars can be seen all the time here in southeast Michigan - it's a far more common occurrence than you might think.
These days, it's rare that an automaker will introduce a model to Canada without offering it up in the United States - especially a car that stands to do big things for a company's presence in North America. But with this 2015 Nissan Micra, that's exactly what's happened; Nissan's US arm has repeatedly stated that there are no plans to offer the car in Yankeeland. Why is the Micra so important? This five-door hatchback enters Canada with the coveted title of being the most affordable new car in the country: just $9,998 Canadian (CAD) to start. In fact, the Micra launches to our north just as the larger, four-door Versa Sedan is phased out in Canada - a vehicle that holds the lowest-cost title here in the US, at $11,990 USD.
