New BMW 4 Series Convertible: 2019 soft-top preps for summer launch

BMW’s new 4 Series Convertible has been spied again, this time on its winter testing programme. Its looks inherit many styling cues from the new BMW 3 Series and these images confirm that the old model’s folding metal hard-top will be ditched in favour of a fabric roof in an attempt to lower the car’s kerb weight.

The new 4 Series cabriolet follows on from the new BMW Z4, which has also opted for a fabric roof in its current generation. The decision will help lower emissions and improve fuel economy, while also limiting the amount of space the roof occupies when its folded into the boot area.

BMW’s new 4 Series Coupe and Convertible will reach the UK market in 2019, and these spy shots show that they will share their sleek looks with the new four-door 3 Series saloon. As such, they get the same swept-back headlights, long bonnet and sculpted bumpers, alongside similarly sculpted flanks, a flat rear-end, and slim LED tail-lamps.

Its interior will also be carried over from the 3 Series, albeit with a few changes. Expect BMW’s latest 12.3-inch digital gauge cluster, alongside a 10.2-inch iDrive infotainment system pre-loaded with sat-nav, real-time traffic info and Apple CarPlay connectivity.

Under the bonnet, the 4 Series Convertible is expected to carry over only the more powerful 3 Series engines. The entry-level units will likely be badged 420i and 420d, using tweaked versions of the current car’s four-cylinder petrol and diesel units. Above this will sit the 430i, as well as the six-cylinder 430d and 440i.

It’s unlikely that the lesser three-cylinder 3 Series engines will feature in the sportier Convertible. At this time, it’s unclear whether the 4 Series will adopt the 3’s forthcoming plug-in hybrid and full-EV powertrains but a flagship M4 Convertible is a given.

Like the 3 Series, we expect the 4 Series will be offered with a range of M Sport accessories, including larger M Sport brakes, lowered adaptive suspension, an electronically-controlled differential. Expect the drop-top version to go on sale in summer this year, priced from around £40,000.
