2019 Mercedes-AMG GLS 63 Gears Up To Take On The Top Luxury SUVs

Introduced in its current iteration about five years ago now, the Mercedes-Benz GLS-Class is starting to grow a little long in the proverbial tooth. Especially with so much fresh competition at the top level of the marketplace for luxury SUVs. Fortunately Daimler is working on a new one, and here we have it.

Spied undergoing winter testing is not just the “standard” version of Benz’s next-generation flagship crossover, but the AMG performance model. You can tell that much from the Panamericana grille, front-bumper intakes, wheels, and brakes – all larger than we’d expect on the lower-powered version.

Under the hood, we’re fully expecting AMG to slot its 4.0-liter twin-turbo V8. The engine produces 571 horsepower in standard guise, and 612 hp in S spec.

And a good thing, too, considering the competition the new GLS will have to contend with. The Bentley Bentayga has been muscling in on the big Benz’s territory, and soon there’ll be new challengers coming in the forms of the BMW X7 and Rolls-Royce Cullinan as well. All the while Land Rover keeps producing more luxurious versions of the Range Rover, with rivals like the Cadillac Escalade, Lincoln Navigator, Lexus LX, and Infiniti QX80 vie for slices of the big luxury sport-ute segment.

The 63 might not be the only AMG version, either, as we could see the mild-hybrid 53 and twelve-cylinder 65 engines slot in under the big hood as well. Of course there’ll be base Benz versions as well, but we’re also anticipating Mercedes to finally produce a Maybach version of the new GLS. That ought to help fend off the advances of the aforementioned Bentayga and Cullinan in an ever-escalating battle for the very pinnacle of the market.

Look for the new GLS to begin reaching dealers sometime next year.

    The proprotions of this already look sooo much better than the first two generations. Really excited to see this.

    This looks so nice! I ca’t wait for it to be debuted.

    I can already see it— even though this and the Telluride were most likely developed at the same time, when KIA reveals the Telluride it’s going to look just like this. And neither one of them have been revealed yet. lol

      Lol, yeah you can definitely see a resemblance in the shape of this vs. the Hyundai/Kia full-size SUVs that are coming. Kind of interesting.

    It’s going to need to really bring it. This class of SUV has gotten seriously luxurious since the current GL/GLS debuted. RR, Lincoln, Bentley, Rolls and BMW all are hitting in this segment or will be. I can see a GLS450 with the new I6 with around 376-385hp, GLS560 with 463hp and the GLS63 with like they stated, 571-600+ hp. The interior needs to surpass today’s S-Class.

    Lincoln is still King right now with its Navigator’s exterior, as well as interior.

    Just about time! I hope this fully redesigned one inside out, help to gain back some of its ancestors glory. In other words, they waited so long to update it.

      I have a massive grievance re the GLS interior still selling in 2018–massive.


    Shock the world…and make it a full electric.
    First company to do that with a full-size luxury SUV will own the category for years to come.
