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.

  • Pig_Iron This message is for Matthew Guy. I just want to say thank you for the photo article titled Tailgate Party: Ford Talks Truck Innovations. It was really interesting. I did not see on the home page and almost would have missed it. I think it should be posted like Corey's Cadillac series. 🙂
  • Analoggrotto Hyundai GDI engines do not require such pathetic bandaids.
  • Slavuta They rounded the back, which I don't like. And inside I don't like oval shapes
  • Analoggrotto Great Value Seventy : The best vehicle in it's class has just taken an incremental quantum leap towards cosmic perfection. Just like it's great forebear, the Pony Coupe of 1979 which invented the sportscar wedge shape and was copied by the Mercedes C111, this Genesis was copied by Lexus back in 1998 for the RX, and again by BMW in the year of 1999 for the X5, remember the M Class from the Jurassic Park movie? Well it too is a copy of some Hyundai luxury vehicles. But here today you can see that the de facto #1 luxury SUV in the industry remains at the top, the envy of every drawing board, and pentagon data analyst as a pure statement of the finest automotive design. Come on down to your local Genesis dealership today and experience acronymic affluence like never before.
