Road tax shown for new vehicles is for the first year from registration. The road tax after the first year of registration will increase by a supplementary amount for years 2 to 6 for vehicles with a list price of more than £40,000 (except for zero emission vehicles).

"Max range" or "Miles per Gallon" figures shown are usually from the Worldwide Harmonised Light Vehicle Test Procedure (WLTP).  These allow comparison between different vehicles as they are based on a standard laboratory test.  Real world results will vary depending on factors including (but not limited to) the accessories fitted after registration, weather conditions, driving styles, vehicle load, vehicle and tyre maintenance including tyre type and pressure (and, for battery electric vehicles, temperature, starting charge of the battery and battery condition)
