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 G20 3 Series platform, it distinguishes itself with a more aggressive design, most notably the large, vertically oriented kidney grille that sparked considerable debate upon its release. Positioned as a sportier, more design-focused alternative to the 3 Series sedan, it offers a blend of performance, luxury, and advanced technology. This generation received a minor facelift (LCI) in early 2024, primarily updating lighting signatures, interior trim, and infotainment. Overall, it's a well-engineered vehicle, but its reliability, particularly for the more complex powertrains, requires careful consideration.
The BMW 4 Series G22/G23 is a compelling choice for those seeking a sporty, luxurious coupe or convertible. Its driving dynamics are excellent, and the interior quality is top-notch. The key to a satisfying ownership experience lies in choosing the right engine and ensuring a diligent maintenance history. For most buyers, the M440i xDrive (B58) is the sweet spot. It offers phenomenal performance, excellent refinement, and the B58 engine is renowned for its robustness. The mild-hybrid system further enhances its appeal. This is an ACHETER recommendation, provided service records are impeccable. The 420i/430i (B48) models are also a strong ACHETER. They provide a great balance for daily driving and are generally very reliable, with fewer complex systems than the MHEV or M models. They are more economical to run. The M4 (S58) is an ACHETER for enthusiasts who understand the demands of a high-performance vehicle. It requires more frequent and specialized maintenance, and running costs will be significantly higher. A thorough pre-purchase inspection by a BMW specialist is non-negotiable. Diesel models (420d, 430d, M440d) are a NÉGOCIER for high-mileage drivers. While efficient and power
