Reading the Bmw 1 Series’s numbers
The Bmw 1 Series passes its MOT first time more often than the average UK car — 79% against 71.4% nationally, across 83,067 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 Bmw 1 Series carries a Band B real-world outcome grade: of the 5,583 people injured while travelling in one over five years of police records, 14.29% were killed or seriously injured — a better outcome share than 54% 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.
