Just days after spy photographers caught the M4 convertible testing with a light layer of camouflage, BMW’s released a series of official pictures of its latest drop-top model before the international premiere at the New York Auto Show later this month.
The M4 convertible uses the same twin-turbocharged inline-six cylinder motor that produces 317 kW and 550 N.m of torque as its M4 coupe and M3 sedan siblings, and which sends drive to the rear wheels via a six-speed manual gearbox or a seven-speed dual-clutch transmission.
Visually, the M4 convertible gains more aggressive visual details over the regular 4 Series drop-trop, such as a revised kidney grille, bonnet bulge, and larger front airdam. The fenders are wider to accommodate the fatter tyres – and the quad tailpipes underneath the revised rear bumper are dead M-car giveaways.
What obviously separates the M4 convertible from its siblings is its three-piece metal roof, which opens and closes in just 20 seconds at speed of up 18 km/h. BMW’s managed to limit the weight gain from the addition componentry to around 250 kg.
The claimed performance figures are nonetheless impressive – with a zero to 100 km sprint taking place in just 4,6 seconds for the manual M4 convertible, and 4,4 seconds in the case of the while the seven-speed dual-clutch ’box.
