"Electric car range figures need to be accurate" – 2023 wish list

As buyers make the switch to electric power, Mike Rutherford believes that a lack of real-world honesty could come back to haunt carmakers

Even an old cynic is occasionally forced to give credit where it’s due. So here goes: most of the all-new models in the showrooms, the latest ICE and EV tech, the driving pleasure bit, the reliability and crash safety standards – they’re all pretty much spot on these days.

My proposed, desperately simple standard is for all sellers to publish the headline/official WLTP range numbers minus 30 per cent ‘TAH’. It stands for Truth And Honesty, qualities that the EV world can’t get enough of during this even slower and trickier-than-expected exodus from ICE cars to pure electric.

Unsure how WLTP tests are conducted? We explain all…
