Where each one leads

• On Canada's official test the most frugal 2003 Infiniti QX4 uses 15.4 l/100 km, the 2006 Mitsubishi Montero 16.0.

Mitsubishi Montero

• Against cars of the same year, the Mitsubishi Montero comes out better in New York safety inspections (fails 2% more often than average) than the Infiniti QX4 (fails 12% more often than average).

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
