You wouldn’t expect Mercedes-Benz to go to the Frankfurt Motor Show without a conceptual study, now, would you?

The marque with the star previewed their upcoming concept car with a picture teasing a part of its rear end that bears the name, “Concept IAA”.

What does “IAA” stand for, you ask? We’ve no idea, but we’re suspecting that Mercedes is playing with the German acronym for the show “IAA” or Internationale Automobil-Ausstellung, which translates to International Motor Show in English.

If it’s not a styling exercise to communicate a change in Merc’s design-DNA and/or future technologies, it could preview an upcoming model like their rumored Tesla-rivaling proposal or a replacement to a current series, but we’ll know for sure in the coming days.
