BMW Série 4 F32/F36 (2013–2020) (2013 – 2020)

Reliability score : 7.8/10

The BMW 4 Series F32/F36 generation, launched in 2013, marked a significant shift for BMW, separating the coupe, convertible, and later the Gran Coupe models from the 3 Series sedan. The F32 is the 2-door coupe, the F33 is the convertible with a retractable hardtop, and the F36 is the 4-door Gran Coupe, offering a sleek, coupe-like profile with added practicality. Positioned as a sportier, more premium offering than its 3 Series sibling, it aimed at buyers seeking enhanced driving dynamics and distinctive styling. Built on the F30 3 Series platform, the 4 Series shared many components, including its extensive range of engines. A significant facelift (LCI - Life Cycle Impulse) occurred in 2017, bringing minor styling tweaks, updated infotainment, and crucially, the introduction of BMW's mor

🎯 Verdict

The BMW 4 Series F32/F36 offers a compelling blend of style, performance, and luxury. However, the overall verdict heavily depends on the specific engine and production year. For pre-LCI models (2013-2016) with N20/N26 (petrol) or N47 (diesel) engines, a cautious approach is advised. These engines are known for timing chain issues that can be very costly. If considering such a model, ensure the timing chain has been proactively replaced with updated components, or factor in the cost of this repair. Oil leaks (OFHG, VCG) are also common on N20/N55 engines and should be checked. The sweet spot for reliability and performance lies with LCI models (2017-2020) featuring the B-series engines (B48, B58, B47, B57). These engines are significantly more robust and address many of the reliability concerns of their predecessors. The B58 (440i) is particularly praised for its blend of power and dependability. The M4 (S55) is a phenomenal performance machine but comes with higher running costs and the rare, but serious, crank hub concern. It's best suited for enthusiasts who understand and are prepared for its specific demands. Overall, the 4 Series is a desirable car, but due diligence is param
