BMW announces the M4 convertible

P90144817_lowResBMW says the newly released M4 Convertible shares the elegant lines of its open-top 4 Series siblings.

Its styling cues – including a signature power dome for the bonnet, exterior mirrors in twin- stalk style and flared front and rear wheel arches bulging over forged light- alloy wheels with mixed tyres in 18-inch (optional 19-inch) format – all identify it clearly as a member of the M3/M4 model family says BMW.

Powering the M4 Convertible is the newly developed six-cylinder in-line engine with M TwinPower Turbo technology and high-revving character already familiar to the M3 Sedan and M4 Coupe. The power unit generates maximum output of 317 kW/431 hp from its 3.0-litre displacement and serves up peak torque of 550 Newton metres across a wide rev band.

The sprint from 0 to 100 km/h (62 mph) takes just 4.4 seconds (with the optional seven-speed M Double Clutch Transmission) – but also sufficient reserves of power to cruise along in relaxed but rapid style with the roof down says BMW.

The M4 Convertible also displays a strict adherence to lightweight construction. The bonnet and front side panels are made from aluminium, as are many components of the high-performance chassis. Added to which, ultra-lightweight and durable carbon-fibre-reinforced plastic (CFRP) is employed in many areas of the new M4 Convertible. The use of CFRP allows the drive-shaft it to be constructed as a single-piece unit. This makes for a significant weight saving and a reduction in rotating masses. The CFRP precision strut in the engine compartment, meanwhile, weighs only 1.5 kilograms yet offers rigidity superior to that of a comparable aluminium component. It plays a key part in the car’s steering response and precision.

The three-section folding metal roof of the M4 Convertible has full interior lining with excellent soundproofing and winter-proof construction says BMW. The roof opens at the touch of a button in under 20 seconds – while travelling at up to 18 km/h (11 mph), if required.

BMW says the new M4 Convertible can also be ordered with a wealth of attractive options to further enhance its appeal, dynamics, and comfort levels. And for that distinctive personal touch, the exclusive BMW Individual range of equipment offers the prospect of a unique driving experience. Special colours and materials can be fine-tuned to the driver’s wishes.
