A camouflaged prototype 2020 BMW 4 Series Convertible has been seen in a cold-weather test ahead of its late 2019 release date. Keep reading for the car’s price, specs and release date

  • BMW 4 Series caught winter testing
  • Specs include a metallic-look soft top roof
  • Price from around £35,000
  • Release date late 2019

The development of the new 2020 BMW 4 Series Convertible continues apace, with the soft-top being photographed during its cold-weather testing programme. The BMW is an alternative to cars such as the Audi A5 Cabriolet and the Mercedes C-Class Cabriolet.

2020 BMW 4 Series Convertible price

Expect the 2020 BMW 4 Series Convertible to cost from around £35,000 when it goes on sale towards the end of 2019. That’s the same as the Audi but undercuts the Mercedes by a welcome £5,000. That’ll buy you a basic model with BMW’s three-cylinder 1.5-litre petrol engine. You’ll easily add £10,000 to that price by going for the top-of-the-range model, with a six-cylinder 3.0-litre engine.

2020 BMW 4 Series Convertible styling

Unfortunately, the car spotted winter testing in Sweden is wearing more camouflage than a sniper who’s been parachuted into arctic combat.

What is obvious, however, is that this BMW 4 Series will get a fabric roof rather than the metal one fitted to the current model.

There are few details about the roof but you can take some cues from the new BMW Z4, which has just gone on sale. Its key feature is that it can be opened in 10 seconds at speeds of up to 30mph.

With no bulky roof to make space for, the new BMW 4 Series will have a more toned rear end than the one that afflicts the current model.

The rest of the look can be pieced together from the just-released BMW 3 Series, which this car is based upon, so it’ll get a large chrome grille and pretty LED headlights.

2020 BMW 4 Series Convertible interior

The same rule can be applied for the BMW 4 Series Convertible’s interior which will be almost identical to what you’ll find in the new 3 Series. So, it’ll get a step up in quality, a large infotainment screen and a host of new gesture-control tech.

The new BMW 4 Series Convertible will be larger than the current model and you can expect that to translate into more rear-seat leg and headroom, which should make it feel reasonably spacious, even for adults.

2020 BMW 4 Series Convertible specs

The BMW 4 Series will get twin-rated dampers that will better absorb bumps, while also feeling firm enough for sporty driving. Use of bonded aluminium in the car’s structure will also allow BMW to reduce the car’s weight by up to 100kg to help improve fuel economy and make it feel more agile in bends.

The range will kick off with a three-cylinder 1.5-litre petrol engine that’ll produce around 150hp and be badged the 418i. It’ll be good for a 0-60mph time of around 9 seconds and fuel economy of around 45mpg. From there, you’ll be able to choose from two 2.0-litre models in the 420i and 430i, while the range will be topped off by the 440i which will get a 3.0-litre, six-cylinder motor producing around 350hp, although fuel economy is likely to be closer to 30mpg.

You’ll be able to have your BMW 4 Series Convertible with a six-speed manual gearbox or an eight-speed automatic, and you’ll also be able to upgrade the car from rear-wheel drive to xDrive four-wheel drive.
