The quickest way to get to 60 mph in the drop-top BMW 4 Series convertible is to choose the range-topping M440i xDrive. The all-wheel-drive setup does indeed add on to the curb weight, tipping the scales just under 4,300 pounds, but this model allows you to make the benchmark sprint in just 4.7 seconds. Other than its premium price tag, there is no other difference between the xDrive and its RWD sibling. Both share the same premium interior, and the assertive styling on the outside that identifies this as the M-powered derivative in the lineup.
