Where each one leads
Citroen C4
Ahead on none of the like-for-like measures.
Škoda Octavia
- Against cars of the same age, the Škoda Octavia comes out better at its first MOT test (passes 4% more often than average) than the Citroen C4 (passes 13% less often than average).
- Fewer Škoda Octavia cars in the Netherlands carry an illogical odometer record (1.7% against 2.9%).
- New Škoda Octavia cars registered in Europe in 2022 average 112 g/km of CO₂ on the WLTP test, against 126 for the Citroen C4 in 2022.
Too close to call: real-world fuel use in Europe, petrol (l/100 km); real-world fuel use in Europe, diesel (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
