Britain just passed the EV tipping point

More than one in twenty of the 40.9 million cars on British roads is now pure electric. Showroom sales passed that mark years ago; this quarter, for the first time, the whole fleet followed.

For the first time, more than one in twenty cars on British roads runs on nothing but a battery. Pure electric cars reached 5.14% of the fleet this quarter, up from 4.04% a year ago, an extra 470,000 cars in twelve months. The fleet here means everything licensed for the road, all 40.9 million cars, not the far smaller pool sold new each year.

The tipping point usually gets declared somewhere else: in the showrooms. Once electric cars pass about five percent of new sales, the theory goes, adoption feeds on itself and the curve steepens. Britain's showrooms crossed that line years ago, and electric cars are now around a fifth of what is sold. The fleet is the harder test. It counts every car that survives from every year before, it only turns over by about a tenth a year, and it does not care what happened in the showroom last month. Moving that whole stock a full percentage point toward electric in four quarters is a supertanker visibly changing heading, and one in twenty of everything on the road is the milestone that matters more than any month of sales figures.

The crossing: electric rising, diesel sliding

The other half of the story is the retreat of the liquid fuels. Diesel has fallen from a 45.9% share at its 2018 peak to 36.6% now, some 2.5 million cars gone since the count topped out in 2019, and petrol is easing too. Between them they still account for five cars in every six, but the direction of travel is now unmistakable, and it runs one way.

The quiet winner this quarter was not the EV at all. It was the hybrid, now 7.4% of the fleet and the single fastest growing fuel type in the release. Britain, it turns out, is still crossing on the bridge, buying the halfway technology in larger numbers than taking the full leap.

And the switch has a geography to it. The fastest growing brands on British roads are overwhelmingly electric ones arriving from China; nearly two in five Chinese brand cars plug in, against about one in thirteen across the fleet. We pull that story apart in The Chinese are coming.

None of this is a forecast. It is a count. And the count says the tipping point people kept placing in the future arrived, quietly, this quarter.
