These are the latest images of the convertible variant of the new
BMW 3 Series, spied undergoing winter testing. Speculation has been rife that the new 3-Series (F33) will be renamed the 4-Series, which will share technical parts with the 3-Series sedan but boast a slightly different front end. Engines from the F30 3-Series will likely power the new coupe and convertible models, so a range of four- and six-cylinder units are expected.
