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 First Drive Review | Wading back into deep waters

NAPA, California — Standing out in a field that includes the Audi Q7, Volvo XC90 and Acura MDX is no easy task. The trio nails driving dynamics, modern style and tech to a tee, putting all the more pressure on InfinitiÂ’s long-awaited revamp of its top-selling QX60. As a sophomore effort to an SUV that lasted well past its best-by date, the 2022 Infiniti QX60 undergoes a substantial overhaul to bring it up to snuff. Does it succeed? We scored seat time in all three rows for answers. Most visibly in this image-conscious segment, the QX60Â’s fully redesigned exterior is a less fussy, more serene look than the previous one, which debuted back in 2013 as the JX35. Gone are the deeply contoured body panels, whose pinched sheetmetal and curved character lines evoked a certain (and increasingly dated) moment in InfinitiÂ’s design language history. The new QX60 flattens many of those creases, bringing a smoother, more monolithic vibe to the table. According to Infiniti senior design director Taisuke Nakamura, the update embraces the concept of “Ma,” which describes a form of Japanese minimalism. WeÂ’re not sure if NakamuraÂ’s “kimono fold” headlights or “origami-inspired” dashboard are readily identifiable as such, but the redesign is nevertheless a handsome one. The 2022 QX60Â’s redux actually gives it a stylistic leg up on some competitors. The QX60 cabin has also been reworked to become a more livable space, starting with a de-cluttered dashboard that incorporates a fully digital instrument panel, an available 10.8-inch head-up display, and a standard 12.3-inch multimedia screen that replaces an 8-inch unit (the last QX60 never got Infiniti's bizarre double-screen tech interface). Standard tech includes wireless Apple CarPlay and Android Auto, six USB ports, a revamped Infiniti Intouch app that adds greater functionality, and the industryÂ’s first integration of remote starting via Alexa voice command. Up front, the interior comes across as sleeker and modernized, with a low-profile expanse of HVAC vents forming a sweep of horizontal lines across the dashboard. Though attractive, their functionality is somewhat hampered by the need to reach into the narrow slots in order to redirect the airflow up or down.  Some of the cabin's luxury touches are a bit heavy handed, like the Autograph trim level's diamond quilting on the dash whose stitches seem thick and indelicately executed.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
