The BMW 4 Series G22 (Coupe) and G23 (Convertible), launched in 2020, represent the second generation of BMW's mid-size luxury coupe and convertible. Based on the CLAR platform, it shares much of its underpinnings with the G20 3 Series, but distinguishes itself with a more aggressive design, most notably the controversial large kidney grille. Positioned as a sportier, more design-focused alternative to the 3 Series, it offers a blend of performance, luxury, and advanced technology. The G22/G23 received a mild LCI (Life Cycle Impulse) update in early 2024, primarily focusing on interior tech and minor exterior tweaks. Overall, it's a well-engineered vehicle with strong performance and a premium feel, though its styling remains a point of contention for some.
The BMW 4 Series G22/G23 is a highly capable and desirable luxury coupe/convertible. Its reliability is generally strong, benefiting from BMW's well-proven B-series engines and the robust ZF 8-speed automatic transmission. The 48V mild-hybrid system, while adding complexity, has proven reliable in its early years. For Diesel Models (420d, 430d, M440d): These are excellent choices for drivers who cover significant mileage, especially on highways. The fuel economy is impressive, and the torque delivery is addictive. However, it is crucial to ensure the car is regularly driven on longer journeys to allow the DPF to regenerate properly. Short city trips will inevitably lead to DPF and EGR issues, which can be costly. Regular AdBlue top-ups and system checks are also vital. If your usage pattern matches, a well-maintained diesel 4 Series offers a fantastic blend of performance and efficiency. For Petrol Models (420i, 430i, M440i): These are generally even more straightforward in terms of long-term reliability, with fewer emissions-related components to worry about. The B58 in the M440i is particularly lauded for its robustness and performance. Overall: The G22/G23 is a RECOMMENDED BUY i
