BMW releases a teaser video of a car that will be unveiled on August 4th. Under the title “Revolution In The Street”, the teaser video seems to hint at a variant of the BMW i3.

The footage was shot through Munich Center, another indication that this could be a city car, or Megacity car as BMW used to call the i3.

Interesting is the fact that the car in the video sounds sportier than the full electric i3 and even louder than the two-cylinder-powered i3 REx.

We believe that a variant of the BMW i3 with a more powerful gasoline engine is unlikely so we’re in the dark so far at what to expect.

What do you think? Is it a BMW i3?  Or a different model, possibly even a new series?
