New mid-sized coupe model could spawn a four-door sport coupe variant as well as a cabriolet version.

These are the very first spy shots of the upcoming coupe version of the new 3-Series F30 rumored to be named 4-Series Coupe.

This is a very early prototype, so it does not reveal much, but we can make out the shape of the upcoming two-door coupe which should be larger than the 3-Series. Or we can imagine it as a smaller version of the 6-Series coupe.

Speculation is that the new 4-Series will feature both two-door and a four-door sport coupe variants (as BMW will be doing with the 6-Series), to compete against the likes of the Audi A5 range, and that BMW may also introduce a cabriolet version too.
