Design & Road Presence

The BMW 4 Series Convertible looks less like a compromise and more like a purpose-built showpiece: a long bonnet, taut shoulders and a slinky fabric soft-top give it a real coupé silhouette even with the roof up. The face is unmistakably BMW with a bold grille that divides opinion but commands attention, and overall dimensions of around 4.77 metres give it a proper grand-tourer stance. From a distance it reads sporty and premium, and up close the detailing — crisp creases and muscular haunches — underlines that this is a car designed to be seen as much as driven.

Interior & Everyday Comfort

The cabin blends modern BMW tech with classic driver-focused ergonomics: a curved display, tactile controls and materials that feel a step above mainstream rivals. Front seats are supportive enough for spirited drives yet comfortable on long runs, while wind insulation from the acoustic soft-top is surprisingly effective at cruising speeds. Controls are logical and well placed, so everyday usability doesn’t suffer beneath the sporty veneer, and it retains the practicality expected of a premium convertible with seating for four in name if not in real-world rear-seat comfort for adults.

Practicality with a Smile

Unlike some convertibles that punish boot space, the 4 Convertible offers a usable 385-litre trunk — enough for two medium suitcases — though the rear bench is tight and best suited to children or short trips for adults. The fabric roof stows and deploys quickly, operating in roughly 18 seconds and even while moving at up to 50 km/h, which makes impromptu topless motoring genuinely convenient. That said, creased luggage and four full-size adults don’t mix well on longer trips, so this is practical in a weekend or city sense rather than as a family hauler.

How It Drives — Poise with Options

Handling follows BMW’s playbook: rear-wheel bias, sharp steering and a chassis that rewards confident inputs while remaining civil on bad surfaces; lighter four-cylinders feel eager and the sixes add smooth mid-range shove. Engine choices span from modest petrols and economical diesel MHEVs to high-performance M variants, with power ranging from about 184 hp up to 530 hp and sprint times quoted between roughly 8.2 and 3.7 seconds 0–100 km/h, so the character can be tailored from relaxed GT to full-blown super-cabriolet. The convertible structure is reinforced enough that body control remains tight, though the trade-off is a slightly firmer ride than the coupe when fitted with larger wheels.

Consumption, Range and Real-World Costs

Fuel use varies by engine: diesel MHEV variants can return around 5.2–6.4 L/100 km, mainstream petrols sit near 6.7–7.7 L/100 km, and the high-output M models climb toward 10.2 L/100 km under spirited driving. In everyday terms this means a diesel 420d can be surprisingly economical for long-distance cruising, whereas the M4 and top M440i will be significantly more expensive to run but offer sports-car performance. Fuel cost aside, ownership also reflects trim and options choices — big wheels, heavy options and frequent open-roof use all nudge running costs and wear upwards.

Tech, Safety and Driver Assistance

The 4 Series Convertible comes equipped with BMW’s latest infotainment ecosystem and driver aids, featuring the curved display layout, voice assistant, wireless smartphone integration and competent sat-nav functionality. Safety tech includes adaptive cruise, lane-keeping aids and automated parking assistants that make city use and motorway miles easier, though none of the features replace attentive driving. The electronic package feels modern and useful rather than gimmicky, with upgrades such as head-up display and advanced park assist available for those who want them.

Who Should Buy One?

The BMW 4 Series Convertible suits buyers after a stylish weekend cruiser with genuine sporting ability: someone who prioritises driving feel and visual impact over rear-seat practicality and cheapest running costs. The range covers sensible diesels for long-distance comfort, punchy petrols for daily enjoyment, and full-fat M variants for those who demand track-capable pace, so there’s a 4 Cabrio for different priorities without changing the character. In short, it’s a premium, image-conscious convertible for those who want an engaging drive with a generous dose of style rather than a pragmatic family car.
