This is the new BMW M4 convertible – and it ditches the old car’s folding metal roof in favour of a more traditional fabric hood. Here’s everything you need to know about this upcoming performance BMW.

  • BMW M4 Convertible rendered
  • Fabric soft-top
  • Will use M4’s 3.0-litre engine
  • 480hp as standard
  • 520hp Competition models
  • To be revealed in 2021
  • Likely to go on sale before 2022

Hot on the heels of the recently revealed BMW M3 and M4 is the new M4 Convertible, and this exclusive rendering shows what it’ll look like.

Our exclusive rendering shows what the new BMW M4 Convertible will look like.

2021 BMW M4 Convertible design

The new BMW M4 Convertible will look almost identical to the new M4 from the front. It’ll sport the same aggressive bumper, scalloped bonnet and vast kidney grilles, along with wider front wheel arches than the standard 4 Series Convertible.

Spyshots of prototypes, such as this, show the new car will come with a folding fabric roof. 

From the side, you’ll spot the M4 Convertible’s new fabric soft-top in place of the outgoing car’s folding metal roof. Folding soft-tops tend to be simpler and lighter than comparable folding hard-tops, which helps keep the car’s weight down and its centre of gravity closer to the road, which helps improve handling.

These M Performance parts (shown on the M4 Coupe) will be offered on the M4 Convertible.

At the rear, the new car will get the same broad brake lights as the new M4, along with four exhausts nestled in a central rear diffuser. You’ll be able to pay extra for a range of BMW M Performance parts – just like on the M3 and M4 Coupe – including a carbon fibre splitter, carbon fibre mirror caps and a set of stacked exhaust tips in a new carbon diffuser, shown above.

2021 BMW M4 Convertible engine and driving

The new BMW M4 Convertible will come with the same turbocharged 3.0-litre straight-six engine as the new BMW M3 and M4. It’ll produce 480hp in standard trim, while Competition-spec cars will pump out 520hp. This power will be sent to the rear wheels through a six-speed manual or an eight-speed automatic gearbox.

The new M4 will soon be offered with four-wheel drive – expect the same for the M4 Convertible.

The new M4 Convertible will likely be a smidge slower than the M3 and M4 thanks to the extra weight of its folding roof and chassis reinforcement, so expect it to reach 60mpg from rest in around four seconds flat. It’s not clear whether this new convertible will be offered with the same xDrive four-wheel-drive system that’ll soon be offered on the M3 and M4.

The Convertible’s cabin will look the same as the Coupe’s, shown here – blue and yellow trim optional.

2021 BMW M4 Convertible interior

The new M4 Convertible will come with the same interior as the new BMW M4 – besides its folding fabric roof, that is. You’ll get more supportive M-branded seats, an M steering wheel with dedicated ‘M Mode’ buttons and a revised centre console with a new gear lever.

As in the M4 Coupe, you’ll be able to customise your M4 Convertible’s cabin with a range of trim in colours including blue and yellow – if you’re feeling brave. Boot space is likely to be a few litres down on the M4 Coupe – after all, that roof has to go somewhere when it folds down.

The M4 Convertible is still being tested ahead of going on sale in 2021. 

2021 BMW M4 Convertible price and release date

It’s likely the M4 Convertible will be offered solely in Competition trim in the UK – as is the case with the standard BWM M3 and M4 Coupe. This means it’ll come with 520hp and an automatic gearbox as standard. It’ll make its public debut in 2021 and is set to cost from around £75,000 to £80,000.
