The open-top M4 has been caught flexing its muscles at the 'Ring.
It's only been a few weeks since BMW lifted the wraps off the new 4 Series Convertible, but the Bavarian automaker is wasting no time putting its M4 sibling through its paces. Our spy photographers recently got up close and personal with the new M4 Convertible, and now the open-top sports car has been caught going for a performance test run at the Nurburgring. While the previous prototype was painted blue, some of the camouflage has peeled away revealing the new prototype's stylish red finish.
The front fascia is still fully camouflaged but we know what it will look like since the covers have already come off the new 4 Series Convertible and M4 Coupe. Yes, that means the M4 Convertible will inherit its coupe sibling's polarizing grille.
Like the regular 4 Series Convertible, the drop-top M4 will sport a soft-fabric roof replacing the previous model's heavier hardtop. The new roof can open and close in 18 seconds up to speeds of 31 mph and is also 40 percent lighter. With the roof down, the new M4 Convertible will be thrilling to drive thanks to its improved driving dynamics and more potent powertrain.
Engine options from the regular M4 Coupe will carry over, meaning the Convertible will pack a 3.0-liter twin-turbo inline six-cylinder producing 473 horsepower and 406 lb-ft of torque in the base model, which will be paired with a six-speed manual transmission.
The output will increase to 503 hp and 479 lb-ft in the Competition variant, with the six-speed manual replaced with an eight-speed automatic sending power to either the rear wheels or an optional all-wheel-drive system. We're expecting the new M4 Convertible to debut either later this year or early next year and go on sale in 2021. When it arrives in dealers, expect to pay a premium over the regular M4 Coupe, which starts at $71,800.
