What is it?
It’s the BMW 4-series family’s drop-top in 428i auto spec, meaning it’s powered by a 242bhp turbocharged 2.0-litre four-pot sending power to the rear wheels via an eight-speed automatic transmission.
The 4-series convertible picks up the baton from the E93 3-series drop-top, gaining 26mm in length and 50mm in wheelbase, while added track width and a 10mm drop in ride height also help it assume a more planted and athletic stance.
The 4-series coupé’s svelte lines aren’t quite recreated in the convertible, though: the three-piece folding hard-top dictating a more angular trailing roofline than that of its fixed-head brother.
Torsional rigidity is 40 per cent higher than in the E93 (which also used a folding hard top), although the new model is claimed to be up to 20kg lighter. That said, our car’s 1775kg kerb weight is a staggering 230kg more than its coupé counterpart’s, and 115kg more than that of the equivalent Audi A5 cabriolet, which uses a lighter fabric roof.
