Mercedes has been on a roll lately with new model debuts. In the last few months, the new Mercedes E-Class Sedan, Coupe, and Cabriolet facelifts have broken cover. However, we're still waiting for the all-new flagship Mercedes S-Class to arrive. Mercedes teased the new S-Class for the first time last month, previewing the sleek new styling. A reveal was slated for later this year, but we now have a more specific timeframe. Speaking to German website Mercedes-Fans, Mercedes' Head of Development, Jurgen Weissinger, confirmed the all-new Mercedes S-Class will debut in early September at the company's headquarters in Sindelfingen, Germany.

Development for the revamped luxury sedan began back in 2015 when the company started building the new platform, so the new Mercedes S-Class has been a long time coming.

Mercedes was planning to show the new S-Class to the world sooner, but development setbacks and the current global situation have delayed its long-awaited premiere. To help reduce costs, "a large number of future models" will share the same platform as the new S-Class, borrowing components such as the shell, safety systems, seats, and climate controls. This platform also supports rear-wheel steering, so expect the new S-Class to have sharper handling and a reduced turning circle.

Weissinger also confirmed the new S-Class will be offered with rear- and all-wheel-drive configurations. For the first time, Mercedes' V12 unit will be offered with all-wheel drive, but it will likely be reserved for the opulent Maybach variant since the Mercedes-AMG S65 is being discontinued.

In the US, the new S-Class will be offered with six- and eight-cylinder units with a mild-hybrid 48-volt electrical system. Plug-in hybrid versions will also offer electric ranges of up to 62 miles, while a fully electric version of the luxury sedan will join the lineup in the form of the Mercedes EQS.

Contrary to rumors claiming the standard wheelbase version will be axed, the new S-Class will once again be offered with three wheelbases: standard, long, and extra long. The standard version's wheelbase will be 1.57 inches longer than the previous model, however. At launch, the Mercedes S-Class will boast level three autonomous driving assists, but Mercedes plans to upgrade them to level four autonomy at a later date. We can't wait to find out how the 2021 Mercedes S-Class will set new standards for luxury cars this September.
