New BMW 4 Series Convertable

Design: Elegant & Sporting

Traditionally, BMW Convertibles have dynamic and balanced proportions – when the roof is up or down – and the new BMW 4 Series Convertible is no exception.

The dimensions of the new car differ significantly from the outgoing BMW 3 Series Convertible. The overall length of 4,638mm has been extended by 26mm; the wheelbase has grown by 50mm and, together with the wider front track, this gives the car a very athletic stance on the road. The shorter overhangs, long bonnet and set back passenger compartment further accent the graceful silhouette.

Although the BMW 4 Series Convertible is a more overtly sporting car than its predecessor, the design of the front end reflects its close family ties with the kidney grille and twin headlights showing it‘s unmistakably a BMW. The optional adaptive full-LED twin headlights, with their hexagonal design, combine with the slightly forward-slanting BMW kidney grille to form a strong stylistic statement. The width of the vehicle is accentuated by a large air intake in the front apron below the headlight line. On the far left and right-hand edges of the air intake are the additional, aerodynamically refined, Aero Curtains.


Three-piece retractable hard-top

The three-piece metal roof of the new BMW 4 Series Convertible means that occupants can enjoy a warm, quiet, snug cockpit whatever the weather outside. A simple push of a button transforms the dynamic coupé into an elegant convertible in just 20 seconds and can now be lowered when the vehicle is travelling at speeds of up 8mph.

The redesigned optional wind deflector is now wider at the sides, and the optional three-temperature Air Collar allows for comfortable open-air driving at low temperatures. The wind deflector is now smaller, lighter, more effective and easier to use. When it is not needed, it can be stored behind the rear seats to save space.

M Sport suspension and brakes

The M Sport suspension included on M Sport models can also be ordered separately, enhancing the dynamic handling characteristics of all variants in the model range. It consists of a firmer spring/damper set-up, stiffer anti-roll bars and tweaked suspension settings to suit the new BMW 4 Series Convertible. BMW also offers the M Sport braking system, which features aluminium fixed callipers (four-piston at the front, two-piston at the rear) and generously sized discs for extremely low weight and very short stopping distances.

Alternatively, there is the Adaptive M Sport Suspension option which adjusts the damper mapping to the road surface and driving situation at any given moment. The driver can also use the Drive Performance Control switch to vary the basic suspension settings between the more comfortable and the sportier ends of the scale. The switch – located on the centre console – has four modes: ECO PRO, COMFORT, SPORT or SPORT+ (in conjunction with the Sport or M Sport trim).


Powertrain: TwinPower technology

The state-of-the-art powertrain technology under the skin of the new BMW 4 Series Convertible ensures it delivers an engaging yet efficient driving experience. As is the BMW custom, the engines are in-line and longitudinally mounted up front, sending their power to the rear wheels. All use BMW’s TwinPower Turbo technology, which combines sporty performance characteristics with exceptional efficiency, and are all EU6 compliant.

The new BMW 435i Convertible heads up the range with its straight-six petrol engine with instantaneous power delivery, refinement and efficiency. Equipped with High Precision Direct Injection and Valvetronic fully variable valve control, the 3.0-litre engine with an aluminium crankcase develops a maximum output of 306hp between 5,800 and 6,000rpm, and peak torque of 400Nm is generated from as low as 1,200rpm through to 5,000rpm. The new BMW 435i Convertible can sprint from zero to 62mph in just 5.6 seconds, on the way to an electronically limited top speed of 155mph.
