Where each one leads
Citroen C1
- Measured by the cars' own fuel meters, the petrol Citroen C1 uses 5.3 l/100 km on the road, the Toyota Aygo 5.5.
Toyota Aygo
- Fewer Toyota Aygo cars in the Netherlands carry an illogical odometer record (2.7% against 3.1%).
Too close to call: MOT pass rate against cars of the same age; official CO₂ of new cars in Europe (g/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
