The next-generation BMW 4 Series Convertible has been spied for the first time, sitting on the back of a truck in Europe.
While the vehicle is essentially fully clothed in a swirly black-and-white wrap, we can see the new 4er resembles the new 3 Series, while it also appears to be dropping the current car's folding metal roof for a fabric one.
That means the next 4 Series Convertible will do away with the hard top that has adorned the last two generations (including the last version of its 3 Series Convertible predecessor), bringing it in line with the smaller 2 Series, outgoing 6 Series and the upcoming 8 Series convertibles.
The use of a fabric roof will save weight, increase luggage space with the roof down, and also save costs for the Bavarian marque.
It's believed the next-generation 4 Series will also borrow several design cues from the new Z4 sports car, including the mesh grille pattern as opposed to the horizontal slats that usually adorn the double-kidney grille.
Under the bonnet, the new 4 Series will likely offer a range of turbocharged four- and six-cylinder petrol and diesel engines, including the "most powerful four-cylinder engine ever to be fitted in a BMW series-production model" destined for the next-gen 3 Series range.
There's also speculation an entry-level three-cylinder could be offered for the first time in the 4er, and we wouldn't rule out a plug-in hybrid version in the future given the industry's push towards electrification.
In terms of timing, the 4 Series coupe and convertible are believed to be scheduled for reveal either late-2019 or sometime in 2020, with a market launch to rollout shortly after.
