BMW Série 8 G14/G15 (2018 – 2025)

Reliability score : 9.2/10

The BMW 8 Series (G14 Convertible, G15 Coupe, G16 Gran Coupe) is a flagship luxury grand tourer that replaced the 6 Series. It represents the pinnacle of BMW's non-SUV lineup, offering a blend of high-end luxury, advanced technology, and sporty driving dynamics. The model received a mild facelift (LCI) in 2022, introducing an illuminated grille and a larger 12.3-inch infotainment screen. Overall reliability is highly rated, particularly for the inline-6 powertrains.

✅ Strengths

Exceptional reliability of the B58 inline-6 engine and ZF 8-speed transmission
High-quality interior materials and build quality
Excellent balance between ride comfort and sporty handling
Intuitive and stable iDrive 7/8 infotainment system

⚠️ Weaknesses

Steep depreciation curve
High cost of consumables (tires, brakes, insurance)
Cramped rear seats in Coupe (G15) and Convertible (G14) versions
Large dimensions make city parking difficult

🎯 Verdict

The BMW 8 Series, particularly in its 840i guise with the B58 engine, is one of the most reliable luxury grand tourers on the market today. It avoids the heavy maintenance costs of the V8 models while providing more than enough power for daily and spirited driving. Highly recommended if the service history is impeccable.
