The all-new and opulent Mercedes-Maybach S-Class is still in its testing phase, although its unveiling should take place in the coming months seen as how the brand new S-Class is already with us.

While there are different types of S-Class prototypes still out there, like the Mercedes-AMG S63 for example, we’re pretty confident that this particular vehicle, spotted by one of our readers in Germany, is the long-wheelbase Maybach flagship.

The biggest clue isn’t actually the size of the rear pillar, but the cutout of the rear door, which is straighter than on the regular S-Class, whose rear door curves around the rear wheel arch due to its smaller size. It also lacks the third rear-window that’s incorporated on the S-Class’ door.

Unlike its shorter wheelbase siblings, the Mercedes-Maybach S-Class might actually retain a V12 engine, although with a mild-hybrid system. The reason we say “might” is because the 2021 Maybach GLS is powered by a twin-turbo 4.0-liter V8 with 550 horses and 538 lb-ft (729 Nm) of torque, and it’s the GLS 600, not 500 or 550.

Powertrains aside, expect the Maybach saloon to feature all of the new S-Class’ driver assist functions, including its Level 3 automated driving capabilities. The carmaker’s Lidar-powered Drive Pilot system will debut next year and will work in both heavy traffic situations as well as on suitable motorways in Germany.

Inside, it should boast a similar setup to the GLS, with two rear seats separated by a large console at the back and a 12.3-inch digital instrument cluster at the front, paired with a 12.8-inch OLED touchscreen display in the middle.

As for pricing, since the current Mercedes-Maybach S-class starts off from around $170,000, we expect more of the same from the all-new car. If the carmaker keeps doing two separate variants like before, then the flagship model will probably cost north of $200,000.
