2019 Infiniti QX50 starts fresh with a new face and trick engine

Last week, Infiniti rolled out the refresh of the big daddy QX80 in Dubai. At this year's Los Angeles Auto Show, the Japanese automaker is poised to reveal something that's bound to be far more mainstream: the 2019 Infiniti QX50 and its trick variable compression turbocharged engine, or VC-T. In addition to the new engine, the QX50 drops rear-wheel drive in favor of an all-new front-wheel-drive platform and gets the new ProPilot assist technology that debuted on the Nissan Leaf. The QX50 may be the headliner, but the engine is the really interesting bit. This 2.0-liter turbocharged inline-four can adjust the stroke of the pistons on the fly, varying the engine's compression from 8:1 to 14:1, and giving the new midsize crossover improved efficiency and diesel-like torque. It's rated at 268 horsepower and 280 pound-feet of torque, down 57 horses but up 14 pound-feet. Front-wheel-drive models hit 60 mph in 6.7 seconds. That drops to 6.2 seconds with all-wheel drive. Combined fuel economy is 27 mpg for front-wheel-drive QX50s and 26 mpg for all-wheel-drive variants, both up from the abysmal 20 mpg combined rating of the current model. Power is sent through a continuously variable transmission. If it's like other Nissan and Infiniti CVTs, it will be inoffensive if a bit lifeless. We've covered the details of this powertrain extensively already, but it's great to see companies giving more life to the internal combustion engine. The new platform marks a big improvement over the outgoing QX50 in terms of platform rigidity and space efficiency. Rear-wheel drive might be fun, but it's never ideal from a packaging perspective. Cargo capacity is up from 31.6 cubic-feet to 37 cubic-feet. With the seats down, the space expands to 60 cubic feet, up from 50.1 cubic feet. That's not exactly class-leading, but it's no longer among the class-worst. The 2019 QX50 will use a new type of high-tensile steel, improving torsional rigidity by 23 percent and shaving overall weight. The styling falls in line with most other Infiniti products. The outgoing model had a bit of an identity crisis, looking more like a lifted wagon than a fully-realized crossover (it was, after all, essentially a G35/G37 wagon). This new one has much more conventional SUV proportions. In fact, it looks like a 7/8-scale version of the new QX80 with a front-wheel-drive profile. That's either good news or bad news, depending on where your tastes fall.

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.

Infiniti hires Sebastian Vettel as Director of Performance

Remember when, during the Grand Prix of the Americas weekend last November, we told you that Sebastian Vettel had worked with Infiniti on the new G Coupe and that there'd be more of that kind of involvement on the way? It's been made official with the three-time Formula One World Champion being named Infiniti's Director of Performance.
Although the announcement is fresh, Vettel's time on the job isn't, Infiniti saying that Vettel went to Japan, the Nürburgring and the Circuit de Catalunya to assist in the development of the Q50 sedan.
When we spoke to Andreas Sigl, the man in charge of Infiniti's F1 collaboration with Red Bull, about the tie-up he had also said, "Like Mercedes has AMG and BMW has M - whether it's called IPL or not - we want to have something in that space." If the brand is still serious about that, Vettel's chops could help them deliver the kind of performance they'd need as upstarts to challenge the ringleaders of that particular hi-po circus.
