The Mercedes-Benz GLC specifications are unusually simple, since both trims cost the same and share 4MATIC all-wheel drive. Only the engine differs between them. A nine-speed automatic and mild-hybrid help feature on each. Both cars weigh much the same and share their running gear. The spec sheet reads almost identically apart from the engine. Grip is equal thanks to standard 4MATIC.
The GLC 300 4MATIC runs a 2.0 litre turbo petrol with 258 bhp and 400 Nm. The GLC 220d 4MATIC uses a 2.0 litre diesel with 197 bhp and 440 Nm. The petrol revs more freely, while the diesel pulls harder low down. Both engines measure close to 2.0 litres.
On fuel the diesel clearly leads at 19.47 kmpl. The petrol GLC 300 returns 14.72 kmpl, respectable for a powerful all-wheel-drive SUV. Read the GLC economy figures tied to each engine, then see what each GLC trim includes.
Length is 4716 mm on a 2888 mm wheelbase, and the 620 litre boot is among the largest here. The tank holds 62 litres and ground clearance is 201 mm. Width is 1890 mm and height 1640 mm. Seating is for five across two rows. The two cars weigh close to the same. The cabin is roomy for the class.
Because both variants are priced identically, equipment does not change with money spent. Your budget picks a fuel rather than a trim level. Standard 4MATIC means neither loses out on grip. Find the GLC on-road total to compare the two fuels fairly.
