According to the independent BMW Blog, the lifestyle model due in 2028 will feature four seats and a classic fabric soft top, similar to the convertible version of the combustion-powered BMW 4 Series. As BMW is developing the vehicle from the ground up as a battery-electric model based on the Neue Klasse platform introduced with the new iX3, it is no longer constrained by the packaging requirements of combustion-engine architectures. This allows for shorter overhangs and a potentially longer wheelbase, creating more interior space and improving comfort despite the compact exterior dimensions.
The design is expected to feature a closed-off front end, aerodynamic wheels and a radically simplified cabin interface.
An i4 Cabrio would underline BMW’s commitment to a high-margin niche segment, despite the recent discontinuation of several other roadster and convertible model lines. Initially, however, the battery-electric model is expected to remain alongside its combustion-powered counterpart.
According to BMW Blog, BMW plans to offer the i4 Cabrio alongside the combustion-engine 4 Series Cabrio (G23). Production of the latter at the Dingolfing plant is reportedly set to continue until mid-2029.
