Mercedes-Benz is preparing to take on the Tesla Model S, Porsche Taycan and next-generation Jaguar XJ with its plush new EQS electric saloon, and fresh spy shots of a less-disguised prototype have emerged.
The newly spotted test car ditches 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.
Last week, Mercedes officially 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 upcoming 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 EQS is described as being roughly the size of the current CLS. Mercedes previously hinted at the styling of its first electric saloon with the EQS Vision concept at last year's Frankfurt motor show.
The latest addition to Mercedes' EQ electric vehicle line-up will join the EQC mid-sized SUV and EQA compact SUV in showrooms in 2021. 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 what the engineering boss of the EQ sub-brand, Michael Kelz, suggests will be a 10-strong electric model range by the middle of the 2020s.
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.
