Reading the Audi A4’s numbers
The Audi A4 passes its MOT first time more often than the average UK car — 72.4% against 71.4% nationally, across 264,163 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 Audi A4 carries a Band C real-world outcome grade: of the 2,485 people injured while travelling in one over five years of police records, 14.93% were killed or seriously injured — a better outcome share than 38% 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.
