The upcoming BMW 4-Series Convertible, which is based on the latest 4-Series Coupe, has been driving around on tests so exposed that BMW might as well not put any camo on it. The car here is a 435i Convertible – we know that from the round exhaust pipes on each side of the rear end.

This is the first time we have spyshots of the 4-Series Convertible with the top down. Our previous set of spy images were of another red example with its metal folding top in place – check out the F33 with its roof up here.
