Test cars have recently ditched the bulky body cladding and fake lights of previous testing mules, giving a glimpse of the headlight and tail-light designs and the overall body proportions. We recently had our first glimpse inside, too, and it looks like the EQS will have the same 11.9in central touchscreen and 12.3in digital display as the recently revealed 2021 S-Class, doing away largely with physical controls.
Mercedes has already confirmed a range of more than 700km (435 miles) for the EQS. Daimler boss Ola Källenius said the new model would also "set the benchmark" in terms of luxury, comfort and safety.
The EQS will compete with the Taycan and its Audi E-tron GT sibling in the flourishing electric premium saloon segment. Test mules feature a low, swooping roofline, with a slim headlight design among the more obvious visible features.
The latest addition to Mercedes' EQ electric vehicle line-up will join the EQC mid-sized SUV and EQA compact SUV in showrooms later this year. According to officials, the EQS name implies a level of luxury, comfort and features consummate to the company’s traditional S-Class.
It will head up a range of six fully electric models under the EQ sub-brand from 2022.
Whereas the EQC is based on existing underpinnings from the GLC, the range-topping EQS will be the first EQ model to benefit from Mercedes' dedicated Modular Electric Architecture (MEA).
Among the key engineering solutions included in the aluminium-intensive MEA platform is a flat floor structure.
In terms of proportions, it has a much shorter bonnet and a more heavily raked windscreen than the S-Class. In combination with the flat floor structure and a near-three-metre-long wheelbase as well as less intrusion from the gearbox and transmission tunnel than in conventionally powered models, this is expected to provide the EQS with greater interior space than Mercedes' current range-topper.
