A premium convertible needs to be many things - bold and extroverted, refined and dynamically capable, and perhaps most importantly, be full of character and personality. After all, no one drives a convertible to be shy about it.

In this sense, the new 4 Series Convertible ticks all the right boxes.

There's no denying the car's bold and attention-grabbing design, headlined of course by the large kidney grille. With its sleek lines and low-slung silhouette, the car has an impactful and elegant design, no matter with the roof up or down.

The interior is typical high-class BMW fare, with plush 'Vernasca' leather, high-tech displays and top-notch finish. And, while four-seater convertibles tend to be on the cramped side, the 4 Series Convertible delivers a reasonable amount of space such that rear passengers can sit pretty comfortably.

A key innovation on this new model is the panel bow soft top, which can be opened and closed in 18 seconds. With the top on, cabin insulation is fantastic, and certainly comparable to a coupe. And with the top down, the car does not exhibit any of the typical 'softness' that one might expect from a convertible.

These technical innovations mean that the 4 Series Convertible drives exactly like a BMW should. It's tight through corners, with accurate steering, and still manages to deliver an enjoyable dynamic experience. Understandably, that's perhaps not what a convertible is chiefly designed for.

A convertible is about the cruising experience, and here it's fully enjoyable. The 2.0-litre engine pumps out a healthy 254bhp and 400Nm of torque, while the suspension is pliant enough that you can be assured of a smooth and relaxing drive.

The 4 Series Convertible is a bold, attention-grabbing car that manages to tread a delightful balance between cruising comfort and the occasional sporty burst, and is a car that's fully defined in its own personality. A sure winner, indeed.
