Where each one leads
Porsche 911
- Against cars of the same age, the Porsche 911 comes out better at its first MOT test (passes 33% more often than average) than the Saab 900 (passes 7% less often than average).
- Against cars of the same year, the Porsche 911 comes out better in New York safety inspections (fails 79% less often than average) than the Saab 900 (fails 26% more often than average).
- Fewer Porsche 911 cars in the Netherlands carry an illogical odometer record (10.0% against 16.2%).
Saab 900
- On Canada's official test the most frugal 1998 Saab 900 uses 11.1 l/100 km, the 2024 Porsche 911 15.5.
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
