2019 Infiniti Q50 Signature Edition brings its flourishes to New York Auto Show

The 2019 Infiniti Q50 Signature Edition is coming to the NY Auto Show as a limited edition version of the sport sedan. Infiniti hopes to draw folks in with a new front and rear fascia, differentiating it slightly from the rest of the Q50s out there. Every Signature Edition will come equipped with the 3.0-liter twin-turbo V6 under the hood that produces 300 horsepower. The bright 19-inch alloy wheels seen on this car are Signature Edition exclusives, according to Infiniti. Then you get your requisite Signature Edition badging on the trunk of this Q50. The inside gets some special touches with "Kacchu" aluminum trim and full leather sport seats. Infiniti makes a bunch of pay options standard equipment on the Signature Edition. These features include Infiniti's ProAssist bundle that includes niceties like blind-spot warning, rear cross traffic alert and backup collision intervention. You get heated seats, a heated steering wheel and navigation, as well. Infiniti is offering the Signature Edition with five different colors: Black Obsidian, Graphite Shadow, Liquid Platinum, Pure White and Iridium Blue. You're looking at the blue in the one photo Infiniti has provided pre-auto show. Infiniti hasn't given pricing or how many Signature Editions it will build, but you'll be able to buy one in May this year. Expect a low number to be available and a higher price for the "exclusivity."

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

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.
