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.

Eau Rouge Lite: Infiniti Q50 gets 400-hp, twin-turbo V6

The Infiniti Q50 Eau Rouge is still (probably) dead. But as consolation prizes go, a new 400-horsepower, twin-turbocharged V6 isn't bad. The 3.0-liter biturbo will be offered in two different states of tune. Enthusiasts will flock towards the aforementioned 400-hp model, but the first VR series engine will also be sold in a 300-hp version, as well. Regardless of output, both engines have a very broad torque curve, ranging from 1,600 to 5,200 rpm with either 350 or 295 pound-feet. A Mercedes-sourced, 2.0-liter, turbocharged four-cylinder will serve as the Q50's new base engine, matching the CLA250's 208 hp and 258 lb-ft of torque. The hybrid powered Q50 soldiers on, as do a line of standard seven-speed automatic transmissions. The naturally aspirated 3.7-liter V6 appears to be gone. Another big enhancement for the updated Q50 is a revised version of the widely disliked Direct Adaptive Steer system. Infiniti says its engineers "optimized the control logic to improve feedback from the road" – a huge area of complaint with the current steer-by-wire system. The Q50's new engine lineup will be showrooms later this winter. Read on for the official press release from Infiniti, and stay tuned for more from the brand – including the new Q60 Coupe – at the upcoming Detroit Auto Show.

Infiniti's Detroit concept to be 'very, very, very, very close' to new Q60

Add one more vehicle to the tally of reveals slated for the 2015 Detroit Auto Show. Alfonso Albaisa, executive design director at Infiniti, has confirmed that the marque will be showing a new concept on January 13, the second media day. More importantly, though, this concept won't be another flight of fancy like many of Infiniti's past show cars. Instead, it will foreshadow the arrival of a replacement for one of its oldest vehicles, the Q60, a model better known as the G37 Coupe. "On January 13, you're going to see a concept car that's very, very, very, very close to the next Q60," Albaisa told Motor Trend. There isn't much to go on beyond that, sadly, although we are free to speculate. Infiniti's past would indicate that the Q60 would carry on its role as a two-door version of the Q50 sedan, with styling influenced by its four-door sibling. While that makes sense, there's also an argument to be made for departing from the Q50's styling in favor of a more expressive look that could allow the two-door model to stand out. Whichever avenue Infiniti chooses, we'll have an even better idea in just a few short months.
