2020 BMW 4 Series Convertible now on sale

• New 4 Series will feature distinctive oversized grilles
• Fabric roof replaces bulky folding metal roof
• UK deliveries to start in March 2021

The new BMW 4 Series Convertible has finally been revealed, several months after the coupe. Besides the distinctive nose, the main difference between this model and the previous one is the fabric roof, which replaces the folding metal one. You can order the new 4 Series Convertible now, with prices starting from £45,785. First deliveries to customers are scheduled in March 2021.

Just like the BMW 4 Series coupe, the convertible will have an eye-catching nose, with darkened headlights sitting either side of two full-height grilles. The grilles are marked out further on the convertible by chrome surrounds. At the rear, there are tinted brake light clusters, large slashes and twin exhausts. The UK line-up is likely to consist of an M Sport model and the powerful M440i xDrive variant. Unlike the previous model, the new coupe won’t get a Sport trim level, so it’s likely the convertible will follow suit.

The 4 Series has a different front end from the BMW 3 Series (on which it’s based) to emphasise the distinction between the two cars. The BMW 4 Series will have a greater focus on performance, so it’ll be offered with the most powerful engines in the 3 Series range.

M Sport trim offers the choice of 420i, 430i and 420d models, which all come with 2.0-litre engines. The petrols offer 182bhp and 254bhp respectively, while the 420d diesel engine offers 187bhp and starts from £47,440. It’ll be joined by a 3.0-litre six-cylinder 430d in July 2021, which will have 282bhp.

The current range-topper, the M440i, has a 369bhp twin-turbo 3.0-litre petrol engine that gets the car from 0-62mph in 4.9 seconds. The M440i also gets adaptive dampers and M Sport brakes, and costs £58,865. Above that will be a 503bhp M4 Convertible, which is expected in 2021.

As with many cars in development, it’s likely a plug-in hybrid version will join the range at some point. If it shares its mechanicals with the BMW 330e hybrid, it’ll feature a 2.0-litre petrol engine alongside an electric motor and a lithium-ion battery. That car offers an electric range of 41 miles, super-low CO2 emissions and up to 289bhp.

The interior is shared almost entirely with the 3 Series, so you can expect the latest version of BMW’s iDrive infotainment system and a crisp digital instrument cluster among the standard equipment. Buyers also get LED headlights, leather sports seats, three-zone climate control and a reversing camera. Moving up to the M Sport Pro Edition trim adds performance upgrades, extra cosmetic touches and bigger wheels.

All of the company’s latest convertibles, including the BMW Z4 and BMW 2 Series Convertible, use a fabric roof now, bringing weight-saving benefits and a more elegant look. We’re told the new roof is 40% lighter than the metal one and can be operated at speeds of up to 31mph. The 4 Series drop-top will rival the Audi A5 Cabriolet and Mercedes C-Class Cabriolet.
