Reading the Mazda Mx-5’s numbers
The Mazda Mx-5 passes its MOT first time more often than the average UK car — 73.8% against 71.4% nationally, across 94,532 real tests. Pass rates reflect the age and upkeep of the cars tested as well as the design — an older fleet drags a model’s rate down.
On safety, the Mazda Mx-5 carries a Band D real-world outcome grade: of the 533 people injured while travelling in one over five years of police records, 22.33% were killed or seriously injured — a better outcome share than 0% of the 129 models we grade. This is a real-world measure shaped by who drives the car and where, not a crash-test score — check its Euro NCAP rating alongside.
