BMW 4 Series Convertible

(2021 - present)

    Summary


    As the name suggests, the BMW 4 Series Convertible is the soft-top version of the 4 Series Coupé, rivalling the Audi A5 Cabriolet and Mercedes-Benz C-Class Cabriolet in the high-end convertible market.

    The 4 Series Convertible has received a very positive reception since its UK arrival in Autumn 2021, reviewers particularly commending the soft-top for its comfortable and refined interior, which comes with plenty of on-board tech as standard.

    Now in its second generation since evolving away from the 3 Series Convertibles of old, the 4 Series Convertible has swapped its predecessor’s folding hard-top roof for a fabric alternative, which Carbuyer says is quicker to take down, and leaves more space for passengers and luggage. That said, Carwow explains that limited rear passenger space and boot capacity still slightly hinders the soft-top’s day-to-day practicality.

    Like almost all modern BMWs, most publications are not convinced by the 4 Series Convertible’s “toothy” grille design. Regardless of its controversial styling, however, the large majority of reviewers are more than won over by the convertible’s impressive performance – the BMW’s agile handling and range of petrol and diesel engines providing driving dynamics that Top Gear calls “fabulous” and The Telegraph “exhilarating”.

    Auto Trader concludes, “The BMW 4 Series Convertible has all the charm and sophistication of its coupé brother with the added bonus of fun in the sun for four.”

    As of August 2023, the BMW 4 Series Convertible holds an Expert Rating of 79%, a score that’s just 2% behind its coupé sibling. It’s also 10% higher than its key rival, the Audi A5 Cabriolet.

    Running costs for the BMW 4 Series Convertible are a bit of a mixed bag, according to numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

    Petrol models offer a below par fuel consumption of 39 mpg on average, while diesel models are much more efficient, offering 53 mpg. Insurance is neither expensive nor cheap, and service and maintenance costs are fairly average too when compared to the rest of the market.
