With its standalone design, brand new soft-top construction, diverse line-up of engines, advanced chassis technology, and impressive levels of standard equipment, the new BMW 4 Series Convertible delivers BMW’s hallmark driving pleasure in a highly exclusive form.
Sharper than its predecessor and echoing the bold style of the BMW 4 Series Coupé, the new BMW 4 Series Convertible blends sporting driving pleasure and open-air thrills. All models feature the M Sport specification as standard, with the new, even more performance-focused M Sport Pro Edition also available.
There will also be a choice of two four-cylinder petrol units and a four-cylinder diesel from launch in March 2021. Two straight-six diesel engines will join the engine line-up later in 2021. The most eye-catching mode is undoubtedly the M440i xDrive Convertible, which offers standout performance courtesy of a 374hp six-cylinder in-line petrol engine, with power transferred to the road via a Steptronic eight-speed gearbox and the intelligent xDrive all-wheel-drive system.
Alongside the car’s proportions, it is the front end of the new BMW 4 Series Convertible that highlights its standalone character. The defining element is its large, vertically emphasised BMW kidney grille, which has a pronounced forward slant and, for optimised cooling, employs large air intakes with a mesh structure as standard. Full-LED headlights are fitted as standard. There is also the option to specify the Visibility Pack, which adds BMW Laserlight and high beam assist.
Its dynamic side profile helps to give the new BMW 4 Series Convertible a low-to-the-road look, while contoured surfaces intensify the car’s high-performance character. The precise lines and three-dimensionally sculpted surfaces of the rear wheel arches combine to give the new BMW 4 Series Convertible a striking look, particularly with the roof down.
The innovative panel bow soft-top on the new BMW 4 Series Convertible blends the strengths of a retractable hard-top and the traditional appeal of a fabric roof. It comprises large panel bow elements with a flush-fitting glass rear window, several layers of insulation and a fabric cover available in Black as standard and Anthracite as an option.
Inside, the BMW 4 Series Convertible’s driver-centric cockpit design features a large screen-grouping formed by the instrument cluster and Control Display. Standard features include electric sports seats in the front with automatically extending and retracting belt feeders, Vernasca leather trim, seat heating and a leather sports steering wheel, plus the clear individual seat design of the two rear seats to emphasise that this is a car built for driving enjoyment.
Mild-hybrid technology features in the new BMW M440i xDrive Convertible and all diesel model variants to boost both performance and efficiency. Fitting a powerful 48V starter-generator and a second battery allows far more braking energy to be regenerated and stored. This energy is used to supply the electrical system, lighten the combustion engine’s workload and increase its power.
The two four-cylinder BMW petrol engines generating an output of 184hp and 258hp in the new 420i sDrive Convertible and 430i sDrive Convertible respectively, with the four-cylinder 420d sDrive Convertible offering 190hp and up to 67.3mpg. The 430d sDrive Convertible and M440d xDrive Convertible both join the range later in 2021, and offer 286hp and 340hp.
The ultimate BMW 4 Series Convertible has to be the M440i xDrive. Powered by a 374hp six‑cylinder in-line petrol engine, the flagship model has a standard specification designed to complement the enjoyment of open-air driving with performance that would be respectable on a racetrack. The M Sport differential, with electronically-controlled, fully-variable locking function in the rear differential, is fitted as standard along with red M Sport brakes, M seat belts, 19-inch light M alloy wheels and the M Adaptive Suspension.
New digital services.
The driver and passengers in the new BMW 4 Series Convertible will benefit from the wealth of possibilities brought by the introduction of BMW Operating System 7. A built-in SIM card with 4G LTE connectivity and the standard Connected Package Professional enable use of the BMW Intelligent Personal Assistant and other digital services, including BMW TeleServices, Intelligent Emergency Call, Real Time Traffic Information with hazard warning, and the Remote Services and Concierge Services.
The standard BMW Live Cockpit Professional features a fully digital screen grouping comprising a digital instrument cluster (with a screen diagonal of 12.3 inches) behind the steering wheel and a 10.25-inch Control Display. The cockpit’s fully digital instrument display provides enough room to accommodate an excerpt from the navigation map, status indicators for the driver assistance systems or 3D visualisation of the surrounding area.
