Infiniti said it will be unveiling its most advanced and most compelling vehicle so far at the upcoming 2017 Los Angeles Auto Show. While the premium carmaker didn’t say that this will be the final production version of its 2019 Infiniti QX50, there has been belief and it is highly likely that this reveal pertains to this particular mid-size sports utility vehicle.
Even before Infiniti reveals the 2019 QX50 – if it would really be the QX50 – the premium carmaker has already leaked a number of details about the next-generation of its mid-size SUV. Most of these details were made known through the Infiniti QX50 Concept that was unveiled at the 2017 Detroit Auto Show earlier this year.
As Infiniti revealed, the new 2019 QX50 will be powered by the VC-Turbo engine, which is the first production-ready variable compassion ratio unit. VC-Turbo technology amazingly combines the power of a high-performance 2.0-liter turbo gasoline engine with the torque levels and efficiency of a diesel mill. Already production-ready, the 2.0-liter VC-Turbo engine offers an alternative to diesel mill, as it could adapt its compression ratio to driving conditions; thereby deliver optimized levels of performance and efficiency. Depending on driving conditions, the engine’s compression ratio could be between 8:1 (for high performance) and 14:1 (for high efficiency).
In the new QX50 application, this VC-Turbo engine is tuned to deliver 268 hp (200 kW / 272 PS) of max output and 280 lb.-ft. (390 Nm) of peak torque, which is comparable to some six-cylinder gasoline powertrains. At this power level, the new Infiniti QX50 could sprint from zero to 60 mph (96.5 km/h) in just 6.3 seconds – when configured with all wheel drive system -- and attain a top speed of 143 mph (230 km/h).
In terms of efficiency, the new VC-Turbo engine is estimated to return 27 mpg (combined) when complemented by a front-wheel-drive system as well as 26 mpg (combined) in all-wheel drive. Compared to previous V6 engines, the new QX50 is around 35 percent more fuel efficient. Power is sent to the front or all wheels through a continuously variable transmission.
The 2019 QX50 is underpinned by a new architecture that is around 23 percent more rigid than the platform underpinning the outgoing model. This new platform allows the QX50 to measure around 4,693 mm (184.8 inches) in length and 1,679 mm (66.1 inches) in height. While the previous model comes with 31.6 cubic feet of cargo volume, the new 2019 QX50 offers 37 cubic feet of cargo space. When the rear seats are folded flat, this cargo volume surges to 60 cubic feet.
Just like the 2018 Nissan Rogue, the new 2019 Infiniti QX50 will be available with Nissan’s ProPilot assist, a semi-autonomous driving technology. With a press of a button, this innovative driving system assists in several vehicle functions like acceleration, braking, and steering input.
