Where each one leads
Porsche 911
- 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 Toyota Supra (fails 63% less often than average).
- Fewer Porsche 911 cars in the Netherlands carry an illogical odometer record (10.0% against 35.6%).
Toyota Supra
- On Canada's official test the most frugal 1997 Toyota Supra uses 13.1 l/100 km, the 2024 Porsche 911 15.5.
- New Toyota Supra cars registered in Europe in 2022 average 181 g/km of CO₂ on the WLTP test, against 278 for the Porsche 911 in 2022.
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
