About the BMW G23 (2021–Present)
The BMW G23 is the convertible variant of the second-generation 4 Series, launched in 2021. Moving from the retractable hardtop of the F33 to a lighter soft-top design, the G23 offers improved performance and a more traditional silhouette. It is powered by BMW’s latest turbocharged petrol engines including the B48 (4-cylinder) and B58 (inline-6), paired with 8-speed automatic transmissions and available xDrive all-wheel drive.
Key features include a digital cockpit, iDrive 7.0/8.0 interface, adaptive suspension, and advanced driver assistance systems. The G23 blends sportiness with luxury and remains a leader in its segment.
