Using these figures
"In lists" shows which yearly VCA lists include the version; it is not the model year. Manufacturers supply figures to the VCA voluntarily, so some makes are missing from some years' lists (for example several large brands between 2019 and 2024); a gap in the years does not mean the car was not sold.

Real-world economy is usually lower than official figures — measure yours with the MPG calculator.
