WLTP figures, VCA lists 2025–2026

WLTP is the official test for new cars from September 2017. Its figures are closer to real-world driving than the older NEDC figures.

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. Click an mpg figure to open the trip fuel cost calculator with it in UK units, or convert it with the fuel economy converter. Real-world economy is usually lower than official figures — measure yours with the MPG calculator.
