Where each one leads
BMW M4
Ahead on none of the like-for-like measures.
Jaguar XK
- Against cars of the same age, the Jaguar XK comes out better at its first MOT test (passes 31% more often than average) than the BMW M4 (passes 7% more often than average).
Too close to call: new York safety inspections failed, against cars of the same year; official combined fuel use, Canada (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
