With a great deal of meticulous detail work and on the basis of the Purpose design, the aerodynamicists, in close cooperation with the designers, were able to achieve a new cd best value of 0.202. This makes the EQS the most aerodynamic production car in the world. The operating range particularly benefits from this. It is also among the best in terms of quiet running thanks to the decreased wind noise level. With ranges up to 784 kilometers (WLTP) and an output of up to 516 hp, the powertrain of the EQS meets every expectation of a progressive sedan in the S-Class segment.

A performance version with up to 630 hp is being planned. All EQS models have an electric powertrain (eATS) at the rear axle, while the versions with 4MATIC also have an eATS at the front axle. The EQS marks the launch of a new generation of batteries with significantly higher energy density. The innovative battery management software, developed in-house, allows updates over the air (OTA). This allows the energy management system to remain up-to-date throughout the life cycle. In terms of the cell chemistry, the cobalt content of the cathodes has been reduced to ten percent.

The EQS can be charged with up to 200 kW at fast charging stations with direct current. Power for up to another 300 kilometers (WLTP) is recharged in just 15 minutes4. At home or at public charging stations, the EQS can be conveniently charged with AC using the on-board charger. In addition, various intelligent charging programs can be activated automatically depending on the location, and functions such as battery-saving charging. With Mercedes me Charge the driver can simply drive to the appropriate charging station2, open the flap, plug in and the current starts flowing: this is how easy the charging process is with the EQS, thanks to Plug & Charge.

Other highlights include the densest network of charging points, with over 90% coverage of public charging points in the USA. The EQS is the first Mercedes to offer the option of activating completely new vehicle functions via over-the- air updates (OTA) in many functional areas. Available from launch: two special driving programs, games and the demo program "The Best or Nothing". This means that, following the purchase and the initial new-car configuration, some of the features of the EQS can be adapted according to personal preferences.
