BMW Série 2 G42 Coupé (2021 – Présent)

Reliability score : 8.8/10

The BMW 2 Series Coupé (G42) represents a return to form for BMW purists, retaining the classic front-engine, rear-wheel-drive layout (CLAR platform) in a compact segment where most competitors have shifted to front-wheel drive. Introduced in late 2021, it boasts exceptional chassis rigidity, near 50:50 weight distribution, and high build quality. In 2023, the interior received a significant update with the introduction of the curved dual-screen display (iDrive 8). While this guide covers all powertrains, a special focus is placed on the 220d (Diesel). Equipped with the B47 2.0-liter turbodiesel engine and a 48V Mild-Hybrid (MHEV) system, the 220d is an outstanding long-distance cruiser, offering a rare blend of high torque, exceptional fuel economy, and robust reliability. It is widely co

✅ Strengths

Exceptional reliability of the B-series modular engines (B47, B48, B58)
The 220d offers an unbeatable mix of torque (400 Nm) and fuel efficiency
Superb ZF 8-speed automatic transmission (standard across the range)
Excellent chassis dynamics and RWD architecture (CLAR platform)
High-quality interior materials and class-leading infotainment (iDrive 7/8)

⚠️ Weaknesses

Heavy curb weight for a compact coupe (often exceeding 1,600 kg)
Cramped rear seats and difficult ingress/egress for rear passengers
No manual transmission option available (reserved only for the G87 M2)
Diesel 220d is not available in North American markets
Controversial exterior styling (subjective, but widely debated)

🎯 Verdict

The BMW 2 Series G42 is a triumph of modern automotive engineering, successfully blending old-school RWD dynamics with cutting-edge technology. The 220d is a standout choice for European buyers: it is arguably the ultimate daily driver for those covering high mileages, offering bulletproof reliability from the B47 engine, punchy performance, and incredibly low running costs. For enthusiasts or North American buyers, the B48 (230i) and B58 (M240i) petrol engines are equally robust. Regardless of the engine chosen, the G42 is a highly recommended purchase, provided the 220d is not subjected exclusively to short city trips.
