BMW's new soft-top. And that's the story here: a cloth roof. The last two generations of this car (one the last to be badged 3 Series, the other the first to carry a 4 Series badge) deployed three-piece folding metal roof mechanisms, sacrificing weight, packaging and some style in the name of better aerodynamics, refinement, and security.
For the new 4 Series Convertible, BMW has had a change of heart, and returned to the classic fabric roof, though it's a lot cleverer than they used to be. Capable of retracting in 18 seconds at speeds of up to 31mph, there's no excuse not to be making the most of all three and a half days of British summertime.
