BMW’s all-new fourth-generation 3 Series Convertible proves itself more than worthy of its market-leading predecessor, with a three-piece retracting steel roof and extra chassis rigidity when the roof is down. The 2.5-litre entry-level 325i is a finely-balanced machine that provides plenty of driving pleasure and surprisingly brisk performance, while the 3.0-litre twin-turbocharged petrol engine in the 335i is a real performance powerhouse, leaping into action with virtually no lag from almost any engine speed and in any gear. With a choice of six-speed manual and automatic transmissions, plus all the luxury fittings you would expect at this level, the luxury convertible segment now has a new benchmark.
