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.

2022 Infiniti QX60 fully revealed with vastly improved design

After a "concept" was shown last September, the significantly redesigned 2022 Infiniti QX60 has finally been revealed. And inside and out, it's a huge design improvement. It has a more traditional SUV exterior, with a much more modern and luxurious-looking interior complete with an infotainment system from this decade. As expected, the production QX60 looks just like the concept, and that's good in our book. It has a boxier, more confident shape but still with the brand's signature curvy detailing. The new two-tone paint is only available on the top-level Autograph trim, though. Interestingly, the new QX60 has the same wheelbase as the crossover it replaces, though it's overall two inches shorter and about an inch taller. Perhaps not surprisingly, the QX60's interior doesn't seem to have changed in size much. Only cargo space has been announced, and while it has 1.4 cubic feet more space with the third row folded, space is down by between 0.4 and 1.4 cubic feet behind the first row and the third row respectively. Space wasn't really the QX60's interior weakness, though — that was in the extremely dated design. Fortunately, the new model tosses everything from the old one out the window. It now has a low, flowing dash that helps provide a more airy feeling. It has the en vogue full-width air vents. It's particularly fetching in Autograph trim as shown above with semi-aniline quilted leather and open-pore wood trim. The infotainment is updated and features a 12.3-inch touchscreen. It can be matched with an available 12.3-inch instrument screen and a 10.8-inch head-up display. Infiniti has added additional sound-deadening, too, and among the standard features are a panoramic sunroof, three-zone automatic climate control, eight-way power heated seats, wireless Apple CarPlay, wired Android Auto and seating for seven. The Autograph swaps the second-row bench for captain's chairs. Powering the new QX60 is a tried-and-true 3.5-liter V6 making the same 295 horsepower and 270 pound-feet of torque as before. But, like its cousin the Nissan Pathfinder, it's now connected to a nine-speed automatic transmission, which also bumped towing capacity up to 6,000 pounds. Front-wheel drive is standard with all-wheel drive available on all trim levels. Infiniti says the all-wheel-drive system has been reworked for faster engagement, and it's able to send up to half of the engine's power to the rear wheels.

2016 Infiniti QX50 is new and improved, kind of [w/video]

The Infiniti QX50 is, to be frank, ancient. It hit the market way back in 2007, and has labored on ever since. Through December of last year, the company only moved 2,727 QX50s. The year before, there were only 2,164 sales, and 3,495 in 2012. What do all three years have in common? The QX50 was Infiniti's slowest seller in each of them. Here's hoping, then, that this latest update will boost the 2+2 crossover's appeal. Being shown today at the 2015 New York International Auto Show, Infiniti has made a number of updates to its smallest crossover, with the most notable being a 3.2-inch stretch in its wheelbase and a 4.5-inch increase in its overall length. That makes for an enormous 4.3-inch increase in the legroom of the formerly cramped second row. Infiniti also made slight increases to the overall ride height, of 0.4 inches in for rear-drivers and 0.8 inches for all-wheel-drive variants. Outside of the dimensional changes, Infiniti also beefed up the former EX37's exterior, with new front and rear bumpers that boast SUV-like scuff plating, as well as LED accents in the new headlights and a new grille that is more in keeping with the brand's current design language. LED taillights sit out back as standard, while Infiniti will happily sell consumers an optional xenon headlight package. Infiniti may have updated the exterior, but the cabin looks largely unchanged, aside from the extra space in the second row. It looks like a complete carryover in terms of features, trim and general layout. Also unchanged is the QX50's 3.7-liter V6 engine. Output remains fixed at 325 ponies and 267 pound-feet of torque. Regardless of whether power goes to the rear or to all four wheels, a seven-speed automatic is in charge of managing the power. We'll have more on the freshened QX50, including live images, coming soon from the floor of the 2015 New York Auto Show.
