Infiniti Offers a Peek at the 2019 QX50(?) as It Prepares New Crossover, Engine for L.A. Debut

Nissan’s luxury division isn’t saying it’s the next-generation QX50, but everything we know about that model and its revolutionary (and potentially risky) engine points to one conclusion.

For now, and until the vehicle’s unveiling at the L.A. Auto Show on November 28th, Infiniti simply refers to it as an “all-new model” — one boasting “world-first” technology. The technology’s no mystery, as after two decades of development Infiniti plans to launch a 2.0-liter variable compression gas engine. Expect class-leading interior volume, the automaker tells us.


Infiniti’s VC-T engine, described in great detail here, regulates piston travel in order to create a range of compression ratios — from 8:1 to 14:1, depending on engine speed and load. Basically, it becomes an engine for all seasons. We already know the engine’s specs — 268 horsepower and 288 pound-feet of torque, which means more twist than the outgoing QX50’s 3.7-liter V6.

If it proves durable over the long term and delivers Infiniti’s claimed 27-percent improvement in fuel economy, it could give Mazda a run for its “reinvent the gas engine” money. (Mazda’s going a different route for fuel savings, introducing a mainly sparkless compression ignition gas four-cylinder for 2018.)

Going by EPA ratings for the 2017 QX50, the incoming model could see a combined rating of 25.4 mpg. Highway mileage would rise to 30.5 percent. That’s far less than contemporary compact hybrid crossovers, but an improvement over rivals like the BMW X3 and Mercedes-Benz GLC. It also allows the automaker to green up its fleet without resorting to expensive battery packs and electric motors.

Any leg up over competitors is a weapon in the premium crossover sales war. Infiniti QX50 sales are down just over 4 percent in the U.S., year-to-date, though October saw sales climb 18 percent, year-over-year.

Granted, the above photo purposefully keeps us (and the vehicle) mainly in the dark. Still, it’s clear the next-gen QX50’s “Powerful Elegance” design, seen last week on the facelifted QX80, hasn’t strayed much from the QX50 Concept released last year.

Normally, we’d spare you from the uncomfortably passionate description of a vehicle from its chief designer, but not this time. Alfonso Albaisa, Infiniti’s senior vice president of global design, describes the upcoming QX50 model as the “perfect balance between lust and logic.”

Lust and logic. You’re welcome.

    20 years of development?! They could have saved (b)(m)illions by adopting my theory: a 2.0L 4-holer; a 3.0L 6-holer; and a 4.0L V8. Turbo- or super-charge as needed. Or both, if they felt lairy-enough about a halo model. A 3.0L V or inline six with a pair of wee turbos would easily put out a reliable 300/300 without the 20 years of expensive development. Forced induction is a known quantity and has been so for longer than 20 years - they could easily have had this up and running with the antiquated VQ, even. That said, don't ever end a sentence with 'even'.

      @sportyaccordy I understand that all car manufacturers produce MPG numbers that are nigh-unattainable in the real world - and that's with proven technology. A '27% increase in fuel economy' covers a lot of ground, too: Idling? Cruising? Hauling? I hope that the buyers of this Rube Goldberg device understand that they're paying for 20 years of R&D that might culminate in 5% of fuel savings - which will be utterly and instantly negated when an example of such is left to warm up in the morning at 0 MPG.

    Willems, you are the stubbornest "auto" writer out there, and perhaps the dumbest. Despite repeated reminders, you still write rubbish like this: "Mazda’s going a different route for fuel savings, introducing a mainly sparkless compression ignition gas four-cylinder for 2018." You are totally incorrect. The acronym for the engine is SPPCI, the first two letters of which stand for SPARK PLUG. Time to exercise what little inquisitiveness you have left and google it. When the engine is under high load and reverts to regular SkyActiv operation, the spark plug fires. When it goes into diesel mode, the spark plug fires a small ball of stochiometric A/F to artificially raise the compression and set the remaining lean charge off. SPARK PLUGS ARE NEEDED all THE TIME. As for the VC engine, it's no miracle and ruins the combustion chamber shape and process at low CR settings. Seeing as you cannot seem to drum it into your head that the Mazda uses spark ignition, not sometimes but always, I shall remind you for ever until you GET it.

      I understand your ire, but let's come up with a better way to express it than to use ad hominem attacks, yeah?

  • Dr.Nick What about Infiniti? Some of those cars might be interesting, whereas not much at Nissan interest me other than the Z which is probably big bucks.
  • Dave Holzman My '08 Civic (stick, 159k on the clock) is my favorite car that I've ever owned. If I had to choose between the current Civic and Corolla, I'd test drive 'em (with stick), and see how they felt. But I'd be approaching this choice partial to the Civic. I would not want any sort of automatic transmission, or the turbo engine.
  • Merc190 I would say Civic Si all the way if it still revved to 8300 rpm with no turbo. But nowadays I would pick the Corolla because I think they have a more clear idea on their respective models identity and mission. I also believe Toyota has a higher standard for quality.
  • Dave Holzman I think we're mixing up a few things here. I won't swear to it, but I'd be damned surprised if they were putting fire retardant in the seats of any cars from the '50s, or even the '60s. I can't quite conjure up the new car smell of the '57 Chevy my parents bought on October 17th of that year... but I could do so--vividly--until the last five years or so. I loved that scent, and when I smelled it, I could see the snow on Hollis Street in Cambridge Mass, as one or the other parent got ready to drive me to nursery school, and I could remember staring up at the sky on Christmas Eve, 1957, wondering if I might see Santa Claus flying overhead in his sleigh. No, I don't think the fire retardant on the foam in the seats of 21st (and maybe late 20th) century cars has anything to do with new car smell. (That doesn't mean new car small lacked toxicity--it probably had some.)
  • ToolGuy Is this a website or a podcast with homework? You want me to answer the QOTD before I listen to the podcast? Last time I worked on one of our vehicles (2010 RAV4 2.5L L4) was this past week -- replaced the right front passenger window regulator (only problem turned out to be two loose screws, but went ahead and installed the new part), replaced a bulb in the dash, finally ordered new upper dash finishers (non-OEM) because I cracked one of them ~2 years ago.Looked at the mileage (157K) and scratched my head and proactively ordered plugs, coils, PCV valve, air filter and a spare oil filter, plus a new oil filter housing (for the weirdo cartridge-type filter). Those might go in tomorrow. Is this interesting to you? It ain't that interesting to me. 😉The more intriguing part to me, is I have noticed some 'blowby' (but is it) when the oil filler cap is removed which I don't think was there before. But of course I'm old and forgetful. Is it worth doing a compression test? Leakdown test? Perhaps if a guy were already replacing the plugs...
