The 430i Convertible is the entry-level open-top member of BMW's second-generation 4 Series, sharing the G22 coupe's CLAR platform but carrying the G23 body code and, for the first time on a 4 Series cabriolet, a fabric soft-top in place of the previous retractable hardtop. Its 2.0-liter BMW B48 turbocharged inline-four produces 255 horsepower and 294 lb-ft of torque with 48-volt mild-hybrid support, driving the rear wheels through a ZF eight-speed Steptronic automatic (xDrive all-wheel drive is offered as a separate variant). The added structure and roof mechanism make the convertible roughly 170 kg heavier than the coupe, so BMW quotes a 0-100 km/h time of 6.4 seconds against the coupe's 5.9, while top speed stays electronically capped at 155 mph. It is positioned as a relaxed boulevard grand-tourer rather than a sports car, sitting below the inline-six M440i and the M4 Convertible.

BMW factory claim for the rear-drive 430i Convertible (6.3 s for the 430i xDrive Convertible). The convertible is slower than the 5.9 s coupe owing to its added weight. Read on the German Wikipedia G22 body-style-specific spec table.
