Mercedes-Benz GLC 2021
The 2021 Mercedes-Benz GLC PHEV offers a blend of luxury and efficiency but is let down by complex hybrid architecture, expensive repairs, and PHEV-specific battery degradation concerns. While the petrol engine itself is robust, the integrated 48V hybrid system, dual-clutch gearbox, and battery management electronics have proven troublesome in real-world ownership. Unless regularly charged, fuel consumption reverts to poor figures for a 2.0L engine, negating the PHEV premise.
