Where each one leads
Land Rover Discovery Sport
Ahead on none of the like-for-like measures.
Mercedes-Benz GLC
- Against cars of the same age, the Mercedes-Benz GLC comes out better at its first MOT test (passes 5% more often than average) than the Land Rover Discovery Sport (passes 1% more often than average).
- Fewer Mercedes-Benz GLC cars in the Netherlands carry an illogical odometer record (2.4% against 4.5%).
- New Mercedes-Benz GLC cars registered in Europe in 2022 average 129 g/km of CO₂ on the WLTP test, against 145 for the Land Rover Discovery Sport in 2022.
- Measured by the cars' own fuel meters, the diesel hybrid Mercedes-Benz GLC uses 6.6 l/100 km on the road, the Land Rover Discovery Sport 7.8.
Too close to call: real-world fuel use in Europe, diesel (l/100 km).
Only measures that do not depend on how many cars were sold: pass and failure rates against cars of the same age, ratings, fuel use and CO₂. How we compare
