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.

2016 Infiniti Q50 gets 2.0L turbo four

After adding a US-built, 2.0-liter, turbocharged four-cylinder to the European and Chinese-market Q50, Infiniti will finally add this engine to the US-spec car. Official details are exceedingly scarce, with the company only saying the 2.0-liter will hit dealers this winter and that additional info will be made available this fall. We can, however, make a few safe assumptions based on the engine's output in Europe. According to our previous story on the Decherd, TN-built engine, the turbocharged mill will offer up 211 horsepower and 236 pound-feet of torque. That plants it squarely between the outputs of the 2.0-liter turbo in the BMW 320i and 328i, though it's down on power compared to the engines offered in the Cadillac ATS, Mercedes-Benz C-Class, and upcoming Lexus IS 200t. There's also a 100-plus-horsepower gap between the Q50's two gas-only engines. Considering all of these things, not to mention Infiniti's reluctance to reveal official specs, it seems safe to wager that the Japanese brand will find a way to squeeze more power out of the current 2.0-liter turbo. That'd allow the Q50 to better challenge the competition's entry-level offerings while bringing the starting price point down from the roughly $38,000 it sits at now. That's grain-of-salt conjecture on our part, though, so caveat emptor. Expect to hear more on the Q50's new engine later this year. Until then, scroll down for the official press release cover all of Infiniti's 2016 updates. INFINITI – WHAT'S NEW FOR 2016 For 2016, the Infiniti lineup in the United States expands once again, literally, with a new longer, roomier Infiniti QX50 premium crossover. With its wheelbase extended 3.2-inches, the 2016 QX50 offers greatly increased rear passenger room, as well as additional cargo space. It also features new exterior styling. There are additional changes in store for 2016, starting with the addition of a new 2.0-liter turbo 4-cylinder engine for the Infiniti Q50 sports sedan available in the winter of 2016. Other Infiniti Q50 enhancements will be announced at the North American International Auto Show in January. In addition, revisions to the Infiniti QX60 luxury crossover will be announced at that time. The Infiniti QX80 full-size SUV keeps it fresh for 2016 with a new Signature Edition, which includes Driver Assistance and Split Bench packages, Saddle Tan high-contrast interior, bodyside moldings and chrome mirror caps. The QX80 Special Edition is limited to just 1,000 units.

Mystery shoppers love Infiniti, hate Tesla

Infiniti, followed by Lexus tied with Mercedes-Benz took the top two spots for best sales experience according to mystery shoppers from the latest Pied Piper Prospect Satisfaction Index, while EV manufacturer Tesla recorded the lowest overall score. Not surprisingly, premium brands dominated the top ranks. Including the three already mentioned, luxury brands occupied seven of the top ten spots and included Audi, BMW, Porsche, and the only American brand to crack the upper echelon, Cadillac. Toyota, Volkswagen, and Nissan rounded out the first ten positions. The news for domestic automakers isn't good. Aside from Caddy, the only other star-spangled automaker to score above the industry average is Chrysler. The rest of FCA, most of GM, and all of Ford fell below the line. But Pied Piper's mystery shoppers handed Tesla the biggest walloping – the company is ten full points below the next lowest brand, Volvo, and its score of 86 is 17 below the average of 103. It's baffling, considering the company's touted direct-sales model. "Tesla leaves me scratching my head," Fred O'Hagan, Pied Piper's president and CEO, told Wards Auto. "They own all of their stores, so you would think each one would be doing the same thing. But they're not. Tesla is consistent in its inconsistencies." O'Hagan added that there's a "huge variation" in Tesla's store-to-store effectiveness, and that in some cases, shoppers found showroom workers that acted more like "museum curators," Wards Auto reports. It might be popular to call Tesla the Apple of the car world, but based on Pied Piper's work, the brand has a long way to go to emulate the uniform shopping experience of an Apple Store. The news might be bad for Tesla, but even for the brands that scored below average, there's cause for celebration. Only Tesla and Mini lost points in this year's rankings, and only Mercedes and Lincoln held steady. Every other brand, including Infiniti, which topped the index for the first time, gained at least one point. The biggest improvements belong to Porsche, Land Rover, and Mitsubishi, which all jumped five points. Pied Piper's annual Prospect Satisfaction Index uses mystery shoppers – over 6,100 this year – from across the country to assess dealers and generate rankings from over 50 individual factors.
