Infiniti's Detroit-bound QX50 Concept is Barely a Concept, Boasts Variable Compression Engine

Infiniti has had enough of the QX50’s voluptuous curves.

An edgier future awaits the brand’s midsize crossover, as shown by photos of the QX50 “Concept” released ahead of the North American International Auto Show. If this concept looks almost production-ready, that’s because it is.

Borrowing heavily from the earlier QX Sport Inspiration concept, the QX50 Concept’s updated design language isn’t the only way Infiniti plans to lure prospective buyers. Underneath the newly creased sheetmetal beats a very different kind of heart — one two decades in the making.

The concept bound for Detroit carries Infiniti’s radical turbocharged variable compression (VC-T) four-cylinder engine. Unlike other 2.0-liter turbos, this mill can be whatever the driver wants it to be.

The VC-T engine allows for greater efficiency and power when the conditions call for it, thanks to its ability to raise and lower the height of the pistons’ reach — a process that takes less than 1.5 seconds. This means both a low-compression (8:1) performance mode and a high-compression (14:1) efficiency setting. Infiniti hasn’t released exact specs, but it’s hoping for 268 horsepower and 288 lb-ft of torque.

Another feature found on the QX50 Concept is the automaker’s ProPilot semi-autonomous driver assist technology. While this isn’t a system that allows drivers to hand over full control to the vehicle, it will take over more of the work.

The QX50 is by no means a segment leader, but it has seen significant interest this year as buyers gravitate towards crossovers and SUVs. The next-generation QX50 should arrive as a 2018 model.

    "its ability to raise and lower the height of the pistons’ reach" Is it antisemitism that prevents Rube's name being mentioned in articles about this approach?

    Just bought the newest car I've ever owned. A (shudder) 03 Saturn Vue. (insert laughs, chortles & guffaws) 155k on the odometer, 4 cyl & trans replaced by the previous owners, 1 did the motor, 1 did the trans, neither did the brakes. So, for half a grand, a pretty looking hoopty that I hope I can get a year of weekly 200 mile beatings.(add more derision, nose coffee, etc) Thank you & sorry to waste your time...

      Congrats on the new car! I'm currently looking for a cash car because I'm bored with driving the RAV everyday (I also have a new CRV that's for the family). I'm targeting something that has had the major components replaced, similar to what you have now. My top choice is Honda (I love Hondas), but I'm pretty open to whatever. Also, it has to have a manual.

  • 3-On-The-Tree My 2009 C6 corvette in black looks great when it’s all washed and waxed but after driving down my 1.3 mile long dirt road it’s a dust magnet. I like white because dust doesn’t how up easily. Both my current 2021 Tundra and previous 2014 Ford F-150 3.5L Ecobomb are white
  • Bd2 Would be sweet on a Telluride.
  • Luke42 When will they release a Gladiator 4xe?I don’t care what color it is, but I do care about being able to plug it in.
  • Bd2 As I have posited here numerous times; the Hyundai Pony Coupe of 1974 was the most influential sports and, later on, supercar template. This Toyota is a prime example of Hyundai's primal influence upon the design industry. Just look at the years, 1976 > 1974, so the numbers bear Hyundai out and this Toyota is the copy.
  • MaintenanceCosts Two of my four cars currently have tires that have remaining tread life but 2017 date codes. Time for a tire-stravaganza pretty soon.
