What Changed

The long-running 3-Series convertible becomes the 4-Series with the 2014 model year. The new model is about 2 inches longer, and 2 inches wider. The track and wheelbase have both increased. Styling changes are subtle: the most visible difference is in the front. Two engines are offered at launch: a 2.0l four-cylinder turbo rated at 240-bhp and a 3.0l turbocharged inline six rated at 300-bhp.
