2021 BMW 4 Series Convertible breaks cover

The new BMW 4 Series Convertible takes the modern route by ditching the old hardtop for a new fabric roof. 

Earlier this year in June, BMW pulled the covers off the all-new 2021 4 Series Coupé, which also marked the debut of the infamous 'XXL-sized' kidney grille. A few days back, we were also greeted by the all-new M3 and M4, and now, the 2021 4 Series line-up seems to be complete, with the arrival of the Convertible.

Over the outgoing 4 Series Convertible, the biggest change (apart from the exterior) on the 2021 model is the replacement of the old retractable hardtop with a new folding fabric soft-top, much like its competitors. The new roof panel is said to be 40% lighter than before and provides better acoustic and thermal comfort. The reduced bulk has also led to an increased boot capacity – 300 litres (80 litres more than its predecessor), with the roof down, and 385 litres (15 litres more than its predecessor), with the roof up.

Of course, the engine options on the Convertible remain the same as the 4 Series Coupé, although, the former gets BMW's xDrive AWD option only on the range-topping M Sport variants. This means the 4 Series Convertible is available with three petrol derivatives (420i, 430i, and M440i xDrive) and three diesel variants (420d, 430d, and M440d xDrive).

While the 420i (181bhp and 300Nm) and 430i (255bhp and 400Nm) are powered by a 2.0-litre four-cylinder engine, the M440i xDrive (369bhp and 500Nm) draws its power from a 3.0-litre six-cylinder unit. In the diesel line-up though, the 420d (188bhp and 400Nm) is the only variant powered by a 2.0-litre (1,995cc) four-cylinder motor. The remaining two variants, the 430d (282bhp and 650Nm) and the M440d xDrive (335bhp and 700Nm) come with a 3.0-litre six-cylinder diesel motor.

All its engines are available exclusively with an eight-speed Steptronic transmission. However, customers can also go for the optional Steptronic Sport transmission, which is being offered with a new 'Sprint' function, which is supposed to help it achieve better, more instant acceleration. All engines, except for the 2.0-litre petrol, also come with 48V mild-hybrid assistance as standard.
