Where each one leads
BMW 5 Series
- New BMW 5 Series cars registered in Europe in 2022 average 108 g/km of CO₂ on the WLTP test, against 212 for the Porsche Panamera in 2022.
Porsche Panamera
- Against cars of the same age, the Porsche Panamera comes out better at its first MOT test (passes 15% more often than average) than the BMW 5 Series (passes 10% more often than average).
- Fewer Porsche Panamera cars in the Netherlands carry an illogical odometer record (4.3% against 4.8%).
- Measured by the cars' own fuel meters, the petrol Porsche Panamera uses 11.2 l/100 km on the road, the BMW 5 Series 11.8.
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
