“Figures from” is the group of build years behind each card's MOT figures. Years where one generation gave way to the next can sit in a wider group until there's enough history to split them.

By build-year group

How each group of build years performs

Each card shows MOT results for one group of Tesla Model Y build years. “Age” means the car's age on the day of its MOT, not its build year. “25+” groups every test on cars aged 25 or older.
