THE new 3 Series Convertible marks BMW’s first folding metal-roofed drop-top and uses a three-piece design to strike a fine balance between strict in-house design parameters and engineering capabilities. The result is a sleek sun-lover that looks almost identical to its Coupe sibling yet does not suffer from the ‘big bum’ syndrome. With much-needed revisions to the iDrive multi-function system for improved useability and the infamous run-flat tyres also receiving some much-needed ride compliance, the 3 Series Convertible is back to reclaim its throne as the most dynamic luxury four-seater convertible. Paired with the already-proven 225kW/400Nm 3.0-litre twin-turbo inline six as first seen in Coupe guise, the range-topping 335i has the right arsenal to conquer.
