The BMW 4 Series Convertible is the soft-top model in the 4 Series range, which in turn is the two-door version of the 3 Series. The 3 Series and 4 Series feature many of the same engines and share many parts, even though they look very different from the outside.

The main difference is the 4 Series’ huge grille. Whether you love or hate it is up to you, but to our eyes it’s certainly bolder and more eye-catching than the styling of its competitors: the Mercedes C-Class Cabriolet and Audi A5 Cabriolet.

The latest 4 Series Convertible gets a fabric roof. The previous version used a folding hard top, but BMW says that new roof technology means the soft-top is just as quiet when it’s up, but it’s lighter and you get more boot space. That holds true in our experience – the new roof isn’t just good for those things, but it’s also quicker to fold away (it takes 18 seconds to do so).

The interior of the 4 Series Convertible is very similar to that of the coupe, which means it’s packed with the latest tech and has high-quality materials that make it feel very upmarket. We particularly like the driving position, which is sporty and comfortable, and the fact that it’s still quiet on the move even with the roof down.

There are plenty of engines to choose from, including three petrol and two diesels. The diesels are the 420d and 430d, offering 187bhp and 282bhp respectively, while the petrol options are the 420i, 430i and M440i. These provide 181bhp, 242bhp and 369bhp respectively and are smooth, punchy, and fun to use.
