Summary

The Mercedes-Benz GLC 450 d 4Matic Coupe (2025) is rated for excellent performance (5.2s 0-100 km/h) and massive torque (750 Nm) thanks to the 3.0 Litre Line 6 MHEV engine. It offers good efficiency (8.0 L/100km) for this power, 4x4 traction and new luxury design (C254). The main downsides are very high maintenance costs, heavy car weight, limited head space and small luggage due to the Coupe style, as well as reported problems with the depreciation system and door locks.
