For most BMW coupes, there will be a matching convertible, so it seems with the Munich marque’s model line-up. Following this line of thought, it is only natural that the forthcoming BMW M8 gets a soft-top version as well, and here it is, in development vehicle form.

With the 6 Series set to grow larger and more upscale, the 8 Series is essentially the development of that model line. Here, the M8 will be the natural coupe and soft-top pairing to the F90 M5, replacing the M6.

Being a full-on M model in this generation of BMWs, the M8 Convertible will likely be powered by a 4.4 litre twin-turbo V8 petrol engine as featured in the F90 M5, producing 600 hp and 750 Nm of torque in the four-door sedan. Its driveline is likely to be similar as well, utilising the M xDrive system and Active M Differential also used in the latest M5, which we’ve sampled in Portugal.

Changes to the chassis will similarly follow a sportier M Division brief, albeit with a calibration specific to the convertible. Other M-specific items can be expected to comprise high-performance brakes, M Servotronic steering, adaptive dampers and powertrain mapping with multiple modes, and M sport steering wheel, to name a few.

As for the exterior, the M8 Convertible is identified by M-specific cues such as larger air intakes in the front bumper, M black kidney grilles painted black, wider wheel arches to house the larger wheel-and-tyre combinations, as well as the quad tailpipe setup which have become the hallmarks of an M car.
