Summary

The Mercedes-Benz GLC 400 d 4MATIC (2021) is rated for excellent performance (5.0s 0-100 km/h) and massive torque (700 Nm) of the V6/Line 6 engine, placing it next to AMG models. It offers good efficiency (8.3 L/100km) for its power and high quality interior (Phase-II with MBUX). The main downsides are the very high maintenance costs of the diesel engine, and the common problems reported with the GLC X253 models, such as 9G-TRONIC transmission shocks at low speeds, premature brake-pedal wear and engine valve defects (reported in NHTSA complaints, source 2.4).
