Where each one leads
BMW X5
- Against cars of the same age, the BMW X5 comes out better at its first MOT test (passes 10% more often than average) than the Mercedes-Benz GLE (passes 6% more often than average).
- Fewer BMW X5 cars in the Netherlands carry an illogical odometer record (3.4% against 4.0%).
- On Canada's official test the most frugal 2026 BMW X5 uses 9.4 l/100 km, the 2018 Mercedes-Benz GLE 13.5.
- Measured by the cars' own fuel meters, the petrol hybrid BMW X5 uses 12.4 l/100 km on the road, the Mercedes-Benz GLE 13.5.
- Measured by the cars' own fuel meters, the diesel BMW X5 uses 9.0 l/100 km on the road, the Mercedes-Benz GLE 9.8.
Mercedes-Benz GLE
- NHTSA rates the 2026 Mercedes-Benz GLE at 5 of 5 stars, the 2026 BMW X5 at 4.
- New Mercedes-Benz GLE cars registered in Europe in 2022 average 105 g/km of CO₂ on the WLTP test, against 113 for the BMW X5 in 2022.
Too close to call: real-world fuel use in Europe, diesel hybrid (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
