2020 Mercedes-Benz GLC 300e PHEV review: Quick drive

Full electric cars dominate the headlines, but partially-electrified alternatives that promise cuts to CO2 emissions while still offering a source of petrol power are rolling out at a rate of knots. Mercedes-Benz’s PHEV (plug-in hybrid EV) plans encompass petrol-electric options from A-Class to S-Class, with SUVs and vans in between. These models sit above internal combustion models with high-voltage (48V) starter-alternators, but below pure electric vehicles (EVs) such as the EQC.
