Hot on the heels of the debut for the 2021 M3 and M4 — and the new 4 Series coupe before that — BMW is giving a first look at the upcoming 4 Series convertible. The four-seat convertible shares much in common with the new 4 Series coupe, including powertrain choices and its gigantic kidney grilles, so be sure to check out our 2021 4 Series coupe preview for more details.

Convertible Top

While the prior-generation 4 Series used a power-folding hardtop, the new 2021 4 Series convertible returns to a soft top that’s also power-folding. The top is available in black or the optional Moonlight Black, which BMW says has a “metallic shimmer, especially in direct sunlight.”

The new, power soft top is 40% lighter than the old hardtop, according to BMW, and also allows for an extra 0.2 inch of headroom. It folds down in 18 seconds at speeds up to 31 mph, and it’s also smaller than the hardtop when folded and stored, allowing for a BMW-measured 9.0 cubic feet of trunk space; that’s 1.2 cubic feet more than in the prior-gen convertible.

BMW also provides a standard wind deflector that can reduce both noise and disruption; it stores either behind the rear seats or in a cargo-area bag.


Safety systems in the new 4 Series convertible don’t differ much from its coupe counterpart, with the notable exception of certain measures to protect occupants, given that either a fabric roof or no roof covers their heads. Part of those changes involve reinforcements to the car’s structure to mitigate the absence of a fixed roof, but also a rollover protection system with pop-up bars that’s triggered if systems intuit an imminent rollover.
