Aksyonov Nikita is the first to finish both of them as renderings. While there is no way of knowing if this is what the real ones will look like, it at least gives us some idea of what to expect.
Starting with the Maybach GLS, this obviously takes inspiration from a couple of sources. The grille is from the S-Class equivalent, which also means it doesn't match the rest of the bumper perfectly. Meanwhile, the fancy wheels were seen on the Maybach Vision concept over a year ago. Of course, the real model won't wear anything as exotic, but there might be some kind of special edition further down the line.
Based on a few patent filing, we have a rough idea about the powertrains as well. The Maybach GLS 600 should offer a few ponies more than a GLS 580 and rely on the same 4-liter V8. Our guess is around 500 HP. Remember, this will be the first Maybach assembled in Tuscaloosa, Alabama.
Meanwhile, the GLS 680 might be a plug-in hybrid with smooth acceleration and 50 km of emissions-free driving. As for the Mercedes-AMG GLS 63, it too will feature a twin-turbo 4-liter V8, though one with a hefty dose of cayenne pepper. We expect the output to be somewhere in the 600-630 HP range.
