When the covers came off the Mercedes-Benz Vision EQS at last year's Frankfurt Motor Show, it's safe to say that most were stunned at the curvaceous, sleek electric flagship that is set to morph into the production EQS. The EQS, of course, will take its place alongside the new S-Class sedan.

Although the production EQS will be more toned down than the Vision EQS, based on spy shots we've seen, it should still prove a more than worthy adversary for the Tesla Model S. Until that becomes a reality, Mercedes decided to give us more insight into the groundbreaking technologies of the Vision EQS and also take it out onto the road in a new video. We also got a better idea of when the production EQS will arrive, although it's not as soon as you think.

In the video, TV host and car enthusiast, Felix Smith, meets up with Gorden Wagener, the chief design officer at Daimler Group, to learn more about the Vision EQS. Smith asks Wagener whether the futuristic steering wheel, which looks like something out of an airplane, would make it to production, but Wagener made no promises.

The Vision EQS is covered with screens, including the entire front grille which accommodates holographic headlamps. The entire dashboard itself is used as a display area for driver information, too, not just the dedicated central screen.

"We are not far from the production car," said Wagener. "The interior is something you will see very soon," he continued, perhaps hinting at an imminent teaser or full reveal of the EQS's cabin.

Elaborating on the sleek appearance and the smart use of space, Wagener explained how the greenhouse blends into the lower body and the upper chrome strip make the whole car look lower. Despite it being about the length of a short-wheelbase S-Class, it offers the interior space of a long-wheelbase version.

Later, an EQS covered in camouflage makes an appearance. Christoph Starzynski, the EQS chief engineer, says it already feels like an S-Class and that the team is hitting its targets. When will the EQS go into production? Starzynski said it will probably be "two more years", which means that it may only arrive as a 2023 model and give the all-new S-Class plenty of time to lay the foundation for the next generation of Mercedes flagship luxury sedans.
