As with all BMWs, performance is a major factor. Whether the top is up or down, the engine will always be ready to tackle the freeway and open road. The 3 Series convertible is no exception. Available with a choice of four or six cylinder engines and a diesel option, power will never be lacking. The base 320i convertible comes with a four-cylinder producing 170 horsepower going from zero to 60 in 9.1 seconds.
Move up a level to the 325i and 330i and you'll experience a six-cylinder producing 272 horsepower. Prefer something a little different? Try one of the diesel engine options. The turbo charged diesel available in the 330d convertible model goes from zero to 60 in only 6.4 seconds and produces lower C02 emissions while doing so.
