Our fearless spy shot photographers captured a film of the 4-Series coupe just last week and now have some snaps of a spied 2013 4-Series Cabrio to share. Internal code names of F32 for the Coupe and F33 for the Cabriolet are being used and slowly we are building up an idea of how the entire 4-Series family will shape up. An automated folding hard-top roof is the obvious talking point of the Cabrio, which has been based on the recently revealed 2012 BMW 3-Series.

Renaming the coupe/cabrio version of the 3-Series is not a shocking thing, considering Audi has been doing the same with the A4 and A5. A four-door sport coupe to rival the Audi A5 Sportback is also something that may feature in the new 4-Series family. The coupe is expected to debut sometime in 2013 and the Cabriolet should follow soon after.
