The all-new BMW M4 Convertible
The arrival of the new BMW M4 Convertible sees BMW M GmbH making another addition to its legendary high-performance sports car line-up. The new M4 Convertible replicates the performance of the new BMW M4 Coupe and M3 Sedan, but emphasizes its stylish and distinctive appearance through its retractable hardtop that places open-top driving at center stage. The new model finds BMW M GmbH drawing inspiration from a long tradition. BMW’s high-performance, top-down sports car enters its fifth generation globally with this new chapter in its history.
The BMW M4 Convertible shares the elegant lines of its open-top 4 Series siblings. Its design language allows it to skillfully blend a distinctive and graceful silhouette boasting finely balanced proportions when the roof is open with an exceptionally dynamic coupe line, shorn of B-pillars, with the hardtop closed. At the same time, the M4 Convertible’s styling cues – including a signature power dome for the bonnet, distinctive front air dam, signature rear apron with four-round tailpipes and flared front and rear wheel arches bulging over forged light-alloy wheels available in 18 or 19-inch design – all identify it clearly as a member of the BMW M3/M4 model family.
Powering the BMW M4 Convertible is the newly developed in-line six-cylinder engine with M TwinPower Turbo technology and high-revving character already familiar from the
M3 Sedan and the M4 Coupe. It generates maximum output of 425 hp from its 3.0-liter displacement and serves up peak torque of 406 lb-ft across a wide rev band. The
BMW M4 Convertible offers the driver not only exceptionally sporty performance attributes – the sprint from 0 to 60 mph takes just 4.2 seconds with the optional seven-speed
M Double Clutch Transmission, 4.4 seconds with the standard 6-speed manual – but also sufficient reserves of power to cruise along in relaxed but rapid style with the roof down.
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 hood and front fenders are made of aluminum, as are many components of the high-performance chassis. Ultra-lightweight and strong carbon-fiber reinforced plastic (CFRP) is employed in many areas of the new M4 Convertible. The drive shaft is just one example. The use of CFRP enables the M4’s driveshaft to be constructed as one single piece which not only offers significant weight saving but a reduction in rotating masses as well. The CFRP high- precision front strut brace in the engine compartment, meanwhile, weighs only 3.3 lbs
(1.5 kg) yet offers rigidity superior to that of a comparable aluminum component. It provides an added measure of steering response and precision.
The BMW M4 Convertible will arrive in US showrooms in summer 2014.
