Autoblog.nl claims that the image below is the new BMW M4 Convertible. The Dutch outlet says that the image scan comes from an official BMW brochure.
The M4 Convertible, along with the M4 Coupe and M3 sedan, will make its debut next summer. The official unveil of the M3/M4 family will take place in January at the 2014 Detroit Auto Show.
The Bi-Turbo Inline 6 Cylinder, 430 hp, 369 lb-ft torque will also power the M4 Convertible variant. The high-revving six-cylinder in-line engine with BMW M TwinPower Turbo technology newly developed for the new BMW M3 Sedan and BMW M4 produces maximum output of approximately 430 hp. Its peak torque soars far beyond 500 Newton meters (369 lb-ft), out stripping the figures recorded by the outgoing BMW M3 by well over 30 per cent.
And yet the engine also achieves a reduction in fuel consumption and emissions of around 25 per cent. The weight of the cars has been reduced to just under 1,500 kilograms, which helps to ensure outstanding driving dynamics and exceptional efficiency.
Design wise, the M4 Cabriolet is built atop the F33 4 Series Convertible, so expect to similar design ideas but with the M treatment.
