Testing, testing… Mercedes’ luxury battery cars assault global roads

  • EQS all-electric Mercedes S-Class range for 2021
  • More models based on new architecture to follow soon
  • EQS first to use new Mercedes electric architecture

STUTTGART, Germany – The new generation of Mercedes electric vehicles in the luxury and executive segment is based on a custom-developed architecture, scalable in every aspect, and expected to be used across model series.

The wheelbase and track as well as all other system components, especially the batteries, are variable thanks to the modular design so the vehicle concept is optimised to meet every requirement of a future-oriented, battery-electric model family.

Such vehicle architecture will make Mercedes-Benz electric cars from saloons to large SUVs.

The EQS will allow luxury segment buyers maximum benefit from all the advantages of an all-electric vehicle of whatever space and design and offer ranges of as much as 700km (according to WLTP). The EQS also meets the requirements of a progressive sedan in the S-Class segment.

”Electric or not,” Mercedes says, ”the brand will remains faithful to its recipe for success in production and will design its vehicles and factories to assemble various models on the same production lines.

”The electric vehicles will also use pioneering cross-sector technology from Mercedes-Benz such as the Mercedes-Benz User Experience control and display system or the driving assistance systems.”

The Vision EQS concept car, Mercedes reminded, gave pointers to the progressive design of the coming EQS back in September 2019 when camouflaged prototypes (see images this article) undergoing testing were also revealing key design features then regarded as revolutionary in the luxury segment – cab forward and coupé-like ‘one-bow’ styling design.

However, further details of the progressive design of the EQS SUV, EQE and EQE SUV crucial for the success of the electric initiative remain a secret…

Mercedes-Benz will introduce the all-electric architecture in 2021 by which time the company should have battery power driving its most-successful platforms – among them the EQC mid-size SUV 4MATIC and the all-electric EQV people carrier.

Customers in the compact car segment can look forward to two all-electric SUVs – the EQA and EQB (A- and B Class). ”Their progressive design,” Mercedes told The Corner in a media release, ”identifies them as members of the all-electric product range… production of the EQA will have started before the end of 2020.


The EQS is (October 2020) undergoing its final testing to validate the overall vehicle quality standards. Stations will include winter testing in Scandinavia, chassis and drivetrain tests on proving grounds, public roads, on the high-speed test track in Nardo as in the heat of southern Europe and South Africa.

Test drives are currently (Oct 2020) also being conducted in China and the USA.

Christoph Starzynski, Mercedes’ vice-president for electric-vehicle architecture at Mercedes-Benz and responsible for the EQ vehicles, said: “The EQS has already piled up far more than two-million test kilometres from the heat of South Africa to the cold of northern Sweden.

“The EQS will be the S-Class of electric vehicles – which is why it’s undergoing the same demanding development programme as any other vehicle bearing the three-pointed star.

”There were quite a few tests specifically for electric cars that cover important development priorities such as range, charging and efficiency.”


The EQS will be assembled with the S-Class in Factory 56in Sindelfingen, one of the world’s most modern automobile factories. Flexibility in those plants has been an investment priority and the technical equipment featuring trailblazing Industry 4.0 solutions is a key factor in such flexibility.

”Highly flexible plants will produce vehicles with various power trains,” Mercedes explained, ”to be able to respond quickly to changes in market demand.”

The company wants electric cars – pure and plug-in – to account for more than half of its sales by 2030.
