2021 BMW 4 Series Soft Top Convertible Unveiled

Added in: News

BMW has unveiled its 2021 4 Series Convertible. Instead of the old hard-top design, the new BMW 4 Series comes with a newly developed soft-top design. This makes the car 40 per cent lighter, allows a greater cargo space and also gives the car a lower centre of gravity for improved handling. The soft-top can be operated at speeds of up to 50kmph. Although BMW India has not officially confirmed anything about the India launch of this convertible but its International deliveries will commence from March 2021.

On the design front, BMW’s large kidney grille has a pronounced appeal and has already gained a lot of attraction these days. This reminds us of the brand’s past and how the company allocates the cooling air to its powertrains in its signature style. The biggest change in the 4 Series is the soft top and the use of that signature slim LED headlights as standard. BMW also allows the buyer to get its Laserlight as an option. Speaking about the soft top, the previous convertible 4 Series featured a folding hard-top, whereas the new version features a lighter cloth roof, that matches with its rivals, the Audi A5 and Mercedes-Benz C-class. The electrically powered soft-top roof takes 18 seconds to open or close and can be operated up to the speed of 50kmph. The roof also adds to the practicality of the car. It is 40 per cent lighter than the hardtop used in the previous 4 Series Convertible and also allows extra cargo and boot space.
