BMW M4 Convertible is here

The BMW M4 Convertible shares the styling with its open-top 4 Series siblings. At the same time, the M4 Convertible's styling cues - including a signature power dome for the bonnet, eye-catching exterior mirrors in twinstalk style and flared front and rear wheel arches bulging over forged lightalloy wheels with mixed tyres in 18-inch (optional 19-inch) format - all identify it clearly as a member of the BMW M3/M4 model family.

Powering the BMW M4 Convertible is the newly developed six-cylinder in-line engine with M TwinPower Turbo technology and high-revving character already familiar from the M3 Sedan and M4 Coupe. The power unit generates maximum output of 431bhp from its 3.0-litre displacement and serves up peak torque of 550Nm across a wide rev band. Top speed is an electronically governed 250 km/h (155 mph). The M TwinPower Turbo engine hits maximum revs of 7,600 rpm.

Like the BMW M3 Sedan and BMW M4 Coupe, the BMW M4 Convertible also displays a strict adherence to the intelligent lightweight construction principle. For example, 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 - thanks to its hugely impressive rigidity - also extremely durable carbon-fibre-reinforced plastic (CFRP) is employed in many areas of the new M4 Convertible. The drive shaft is one example, the use of CFRP allowing 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 therefore plays a key part in the car's excellent steering response and precision.

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