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."

The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.

2019 Infiniti QX50 First Drive Review | A high-tech engine flies under the radar

Update: An Infiniti representative reached out after this review was published and noted that the "Park with Easy Steering" function of the Direct Adaptive Steering system was erroneously left engaged. Infiniti says this feature "reduces feel considerably at low speeds to aid in parking", and that the Easy Steering function will be disabled by default in customer cars unless the customer chooses to engage it. This seems to explain the issues our reviewer had with low-speed steering feel, although we've had other problematic experiences with Direct Adaptive Steering in a broader sense – not to mention the fact that the drive-by-wire system has been recalled several times to fix various issues, and also recalibrated in response to criticism. We hope to get another QX50 soon, and if so we'll compare the low-speed steering response with Easy Steering on and off. Even as manufacturers rush headlong into electrification and autonomous driving, revolutionary internal-combustion engine technologies are still being developed. Consider the Mazda Skyactiv-X Spark Controlled Combustion Ignition process, for example. But Infiniti's VC-Turbo four-cylinder engine, which makes its debut in the 2019 QX50, is truly a work of engineering fortitude. The engine realizes the long-held ambition among engine manufacturers to create a way to alter the compression ratio on the fly, a boon to both power and fuel efficiency. It's a brilliant bit of science that's, unfortunately, still in search of the right car. Don't get us wrong, the QX50 is perfectly competent — it's an exceedingly quiet and comfortable cruiser. However, it's no longer the driver-pleasing machine its predecessor was. That car, originally known as the EX35, was built atop Nissan's sporty FM platform, a front-midship, rear-wheel-drive layout putting the engine aft of the front axle line and giving the vehicle the athletic driving dynamics of a sport sedan. In fact, it was basically a G37 hatchback, and it was sold as the Skyline Crossover in Japan. A shortened FM chassis underpinned the 370Z, to put a finer point on it. For those more concerned with comfort than corners, the 2019 QX50 might actually be a more useful. It rides atop an all-new front-wheel-drive chassis, which means it's able to add more space for both passengers and cargo. It trades a heap of the old QX50's sportiness for comfort and packaging efficiency. If that sounds good to you, perhaps the new QX50 is the right crossover.
