Where each one leads
BMW M4
- Against cars of the same year, the BMW M4 comes out better in New York safety inspections (fails 58% less often than average) than the Dodge Challenger (fails 38% less often than average).
- New BMW M4 cars registered in Europe in 2022 average 229 g/km of CO₂ on the WLTP test, against 287 for the Dodge Challenger in 2022.
Dodge Challenger
- On Canada's official test the most frugal 2023 Dodge Challenger uses 10.3 l/100 km, the 2026 BMW M4 12.6.
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
