Next week, Mercedes will preview a new member of the EQ family with an electric concept car at the Frankfurt Auto Show. Recent teaser photos have confirmed it will be an electric sedan concept and will join the existing EQC SUV and EQV van when it enters production.

Essentially, it will be the electric equivalent to the flagship S-Class sedan and Mercedes' answer to the Porsche Taycan. Details are still scarce, but a new teaser video posted by Mercedes on social media confirms the concept will be called the Vision EQS.

"A lasting beauty that moves you. First details of our vision of sustainable modern luxury. The all-electric Mercedes-Benz VISION EQS live in Frankfurt on September 10th, 2019," the caption of the video reads.

While previous teaser photos have shown the Vision EQS hiding under a sheet, Mercedes' new video teaser gives us a first look at the electric sedan's familiar face. Like the EQC, the Vision EQS has a large illuminated Panamericana grille but we don't get to see the shape of the headlights to compare them with other EQ models.

We'll have to wait until the Vision EQS debuts at Frankfurt to see the rest of the design details, but Mercedes has already revealed the concept's luxurious interior. The cabin looks even more spacious than the S-Class, incorporating individual rear seats separated by the center console that runs along the entire length of the cabin.

The futuristic and high-tech interior also has an abundance of screens, including a fully digital cluster and a massive touchscreen integrated into the center console for the infotainment system. No doubt there will be an advanced self-driving system, too, especially as the next-generation S-Class is expected to offer Level 3 autonomous tech next year. Mercedes will lift the wraps off the Vision EQS Concept next week at the Frankfurt Auto Show, where the new 2020 AMG GLB will also make its public debut.
