The new BMW 4 Series Convertible.

The new BMW 4 Series Convertible heralds a new era in the premium mid-size range of open cars offered by BMW. The new BMW 4 Series Convertible is setting new standards in terms of dynamics, elegance and extraordinary driving pleasure -- with the top up or down. In addition to having its own distinct design, the BMW 4 Series Convertible sets itself apart from its BMW 3 Series cousins through a number of distinguishing technical features. The new BMW 4 Series Convertible is visibly larger in width, track and wheelbase than the BMW 3 Series Convertible.
