The Mercedes-Maybach GLS debuted exactly two years ago but engineers and designers already working on an update to the flagship SUV as seen by this lightly camouflaged prototype that our spies caught in Europe.

The most luxurious variant of the GLS will go through mild visual updates in order to stay up to date and in line with the more modern S-Class. Starting from the front, the seven-seater looks virtually unchanged, featuring Maybach’s unique grille and bumper design, although this might be the case only for this early prototype with more changes coming to later models.

The same applies to the profile where we can see the multispoke 22-inch wheels and electronically reclining side steps for easier ingress/egress. What seems to have changed is the rear end, with a portion of bodywork around the taillights being camouflaged. While the shape of the horizontally-arranged lighting units appears to be similar, the LED graphics are now different.

Inside, the updated model is rumored to get updated graphics for the digital instrument cluster and the central touchscreen with the latest version of the MBUX system. At some point, the GLS will inherit the new screen layout that debuted last year on the S-Class and has already found its way into the SL, however, such a big change might not happen during this minor facelift. It is possible though that the Maybach GLS will get the new three-spoke steering wheel from the sedan.

Under the bonnet of the GLS 600 we expect the usual twin-turbo 4.0-liter V8 producing 550 hp (410 kW / 558 PS) and 730 Nm (538 lb-ft) of torque mated to the EQ Boost 48-volt mild hybrid system which is good for an additional 22 hp (16 kW / 22 PS) of power and 250 Nm (184 lb-ft) of torque. We may see some minor power and fuel efficiency improvements across the range.

The updated version of the heavyweight Mercedes-Maybach isn’t expected before early 2023, when it will compete with the likes of the facelifted Bentley Bentayga, the brand new Range Rover, and the higher trim levels of the upcoming BMW X7 facelift.
