The new BMW 4 Series Convertible


The sporting prowess and exhilarating driving experience of the new BMW 4 Series are taken to even greater heights with the addition of the new Convertible version.

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 the brand’s hallmark driving pleasure in a highlyexclusive 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-airthrills to continue the 35-year legacy in this model class that began with the first BMW 3 Series Convertible.

All models feature the M Sport specification as standard, with the new, even more performance-focused M Sport Pro Edition also available. In addition, both specifications can be upgraded with the Technology Pack – one of several option Packs that enable a high level of personalisation.

The new arrival to the sixth model generation’s model range – the BMW M440i xDrive Convertible – 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.

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 new BMW 4 Series Convertible will be built at BMW Plant Dingolfing.

Exterior design: distinctive, sporty and elegant

The striking proportions and stylish elegance of this open-top four-seater follow the lead of the BMW 4 Series Coupé and ensure the car’s sporty profile. 

At the same time, the brand’s new design language has produced a distinctiveinterpretation of the low-slung silhouette long-established as a signature feature of midsize BMW convertibles. 

The newcomer’s powerful presence also stems from its larger exterior dimensions. At 4,768 millimetres, it is 128mm longer than its predecessor, while width has increased by 27mm to 1,852mm and the wheelbase by 41mm to 2,851mm. With the roof closed it stands at 1,384mm. It also benefits from increased track widths (+ 28mm at the front, + 18mm at the rear).

Front end with expressive, tradition-rich styling highlights 

Alongside the car’s proportions, it is the front end of the new BMW 4 Series Convertible that highlights its standalone character and distinguishes it most clearly from the new BMW 3 Series Saloon. The defining element is its large, vertically emphasised BMW kidney grille, which – as on the new BMW 4 Series Coupé – 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. BMW Laserlightincludes the adaptive cornering function with variable road illumination optimised for urban and motorway driving and, at speeds above 37mph, increases high-beam range to a maximum 550 metres and follows the course of the road.

New darkened headlights are also available for the M440i xDrive as part of the exclusive Shadowline Pack. Other variants can also be fitted with these stylish headlights if the optional performance-focused M Sport Pro Pack is chosen.  

Dynamic side profilepowerful stance, elegant roofline

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. This impression is reinforced by the slim rear light units extending into the flanks. The lights are darkened, with their rear bars illuminating to reproduce the L shape familiar from other BMW models. When closed, the roof flows into the car’s shape to reinforce its sporty appearance.

New panel bow softtop: comfort, timeless style and minimised weight blended into one

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. The acoustic and thermal comfort of the panel bow soft top roof are far superior to that on a conventional soft top. It also 40 per cent lighter than the outgoing model’s retractable hardtop.

The roof is powered by an electric motor that enables it to open or close within 18 seconds at the push of a button, including while on the move at speeds up to 31mph. The variable soft top compartment allows luggage capacity to be increased from 300 to 385 litres when the roof is closed.

Interior: premium seating for four with an emphasis on refinement and driving enjoyment

The BMW 4 Series Convertible’s driver-centric cockpit design features a large screen-grouping formed by the instrument cluster and Control Display. The ergonomically-optimised arrangement of the controls emphasises that this is a car built for drivingenjoyment – as do standard features including 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.

M Sport as standard. M Sport Pro Edition for even more excitement

Every BMW 4 Series Convertible comes with the M Sport specification as standard.This includes large front air intakes, a sculpted rear apron, M Sport suspension, 18-inch M light-alloy wheels, sport seats upholstered in Vernasca leather trim, knee pads on the centre console and a Sensatec dashboard. 

The Live Cockpit Professional, Ambient Lighting, electric seats, reverse camera, reversing assist, Welcome Light Carpet, three-zone automatic climate control and 10.25-inch CID are also included in the generous standard specification. 

Customers can opt for the M Sport Pro Edition specification, which adds such highlights as Jet Black 19-inch M light-alloy wheels, a choice of three Individual paint shades – Tanzanite Blue, Dravit Grey and Aventurin Red (from 07/21) – and the M Sport Pro Package. This package encompasses a selection of features including darkened headlights, M seatbelts, the new Sprint Mode, Adaptive M Suspension and Enhanced Active Sound Design that delivers a sporty engine soundtrack in the interior.

M440i xDrive: the ultimate BMW 4 Series Convertible

New to the BMW 4 Series Convertible line-up is the M440i xDrive.

Powered by a 374hp sixcylinder 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.

Four- and six-cylinder engines with BMW TwinPower Turbo and mildhybrid technology for greater performance and efficiency.

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 starter-generator produces an electric boost effect that instantly delivers an additional 11hp for overtaking or even quicker getaways off the line.

The 374hp straight-six engine under the bonnet of the flagship model is joined in the range by two four-cylinder petrol units, generating an output of 184hp in the new BMW 420i sDrive Convertible and 258hp in the new BMW 430i sDrive Convertible. The entry-level unit delivers combined fuel consumption of up to 49.6mpg and CO2 emissions from 140-131g/km, while the more powerful version’s figures are 47.1mpg and 147-138g/km.

A 190hp four-cylinder diesel engine, featuring BMW TwinPower Turbo technology with twostage turbocharging, powers the new BMW 420d sDrive Convertible. It returns combined fuel consumption of up to 67.3mpg, with CO2 emissions of 119-111g/km, while the similarly-turbocharged BMW 430d sDrive Convertible, which is due to arrive later in 2021, delivers figures of up to 50.4mpg and 147g/km.

Two turbochargers of different sizes ensure exceptionally rapid power delivery in the forthcoming BMW M440d xDrive Convertible. Its strong performance is complemented with combined fuel economy of up to 44.8mpg and it emits 165g/km CO2.
