The second-generation Mercedes-Benz GLC (X254) is based on the MRA2 platform, shared with the C-Class (W206). Launched in late 2022 (2023 model year), it marks a gentle stylistic evolution but a technological and mechanical revolution. All engines are now electrified, ranging from 48V mild-hybrid (MHEV) to plug-in hybrid (PHEV) equipped with a huge 31.2 kWh battery offering over 100 km of electric range. Although demand for gasoline and PHEV is increasing, diesel remains a major pillar for this model, particularly in Europe for high-mileage drivers. The OM 654 M (M for Modified) block has been reworked (displacement increased to 1993 cc, increased injection pressure) and coupled with a second-generation integrated starter-generator (ISG) housed in the 9G-TRONIC gearbox.

The Mercedes GLC (X254) is a concentrate of technology that dominates its segment in terms of comfort and energy efficiency. For high-mileage drivers, the 220 d or 300 d diesel (OM 654 M) is the absolute preferred choice. It offers reassuring mechanical reliability, negligible consumption for its size, and high-level driving pleasure thanks to mild hybridization. PHEV versions (including the unique 300 de diesel) are impressive on paper, but their technical complexity and massive overweight encourage caution for a long-term purchase (out of warranty). If you buy a 2023 model, ensure that all recalls (especially electrical and fuel pump) have been carried out and that the MBUX system is up to date to avoid early production electronic inconveniences.
