Right now, Porsche is eating up the headlines with its Taycan electric sedan. Mercedes' EQ division is probably looking for plenty of that action as it prepares to bring its long-rumored EQS electric sedan into the spotlight. As of now, we've seen the EQV van and EQC crossover SUV production models, as well as the compact EQA concept car. Given the naming convention, we can safely assume the EQS will be the sedan hiding under the cloth in the single image that Mercedes has used to put the media on alert for its Frankfurt debut.

There's not much to glean from the single image of what, assuming it is a sedan, we suspect will be the electric equivalent of the Mercedes-Benz S-Class. All we can make out is the three sleek looking dotted running lights and the hint of how big the grill will be with its large glowing Mercedes star badge. Given the running lights, it looks like the headlights could be a departure from those on the EQC. Chances are though that Mercedes will continue the blue accent lights that have become a trope for electric cars.

How the EQ design language adapts or evolves from the models we've seen will be interesting to see. No additional details have been given so we're as much in the dark as everyone else at the moment and waiting for its reveal at Frankfurt. The 2019 Frankfurt Auto Show doesn't start until September 10, so that means we'll see the Porsche Taycan electric sedan debut first on September 4.

It's unlikely the two will comparable though with the Taycan aiming to be a pure-blooded sports sedan and, most likely, Mercedes aiming to do what it does best in the premium and luxury department. Mercedes will most likely have Tesla in the back of its mind as the real competitor.
