We have another look at the forthcoming BMW 4 Series Cabriolet – now, we get a closer look at it and into its cabin. Inside, the Cabriolet gets the dashboard architecture of the G20 3 Series, here equipped with the latest iteration of the M Sport steering wheel. Also seen here from the latest BMWs, albeit switched off, is the dual widescreen setup for driver instrumentation and infotainment.

Codenamed G23, the open-air 4 Series will revert to a fabric roof construction in place of the folding hard top that had previously been in place. This offers a few benefits, namely additional reduced weight and additional luggage capacity due to the more compact folding roof assembly.

As before, the 4 Series in both coupe and convertible forms will mirror the 3 Series in terms of engine range, and should comprise a mix of four- and six-cylinder units. The G20 3 Series engine line-up comprises a 2.0 litre with outputs between 184 hp/300 Nm and 258 hp/400 Nm, with a plug-in hybrid in the mix as well.

Should there be a six-pot version of the soft-top, motive power will come courtesy of the 3.0 litre turbocharged inline-six from the M340i, which produces 374 hp and 500 Nm of torque in the sedan application. The caretaker flagship – until the full-fledged M3 arrives – sends its outputs to all four wheels, and the same will be the case should there be an ‘M440i’ convertible. All versions are expected to use an eight-speed automatic.
