Plug-in hybrids have been the fastest-growing type of car sold in Britain. There is a catch buried in the specifications, and new research has dragged it into the open. The Guardian reports that three-quarters of the twenty best-selling plug-in hybrid models in the UK cannot use rapid chargers at all.
The analysis comes from ChargeUK, the body that represents the public charging industry. It found only 26% of vehicles sold across the top twenty models, which include the Jaecoo 7, the Ford Kuga and the Hyundai Tucson, can accept chargers with a power of 50kW or more. Not one of them can use the ultra-rapid tier, which starts at 150kW and adds serious range in minutes rather than hours.
Why does that matter? Because a car that cannot charge quickly on a motorway trip mostly will not charge at all on one. Rapid and ultra-rapid points make up about a quarter of the UK’s public charging network but deliver the bulk of its capacity. Drivers limited to slower speeds face waits of several hours where a pure electric car would be gone in twenty minutes.
For comparison, every one of the top twenty pure electric models sold last year could use rapid chargers, and 64% could use ultra-rapid ones.
ChargeUK chief executive Shane Brennan did not mince words. A plug-in hybrid that is never plugged in, he said, is “a costly petrol car pulling round a heavy battery”, and government should not be hoodwinked into treating stronger PHEV sales as meaningful electrification. He called the mythical PHEV compromise “a spectacular own goal”.
The sales numbers explain why this is a live policy fight. Around 227,000 plug-in hybrids were registered in the UK last year, up almost 35% on 2024, and a further 180,000 have gone out so far this year. Carmakers lean on them because they cover the ZEV mandate while soothing range anxiety. The government allowed manufacturers to count more of them towards electric targets last year.
Independent studies have repeatedly found PHEVs emit far more in real driving than the official test figures suggest, and the government’s own consultation document now concedes that the calculation method significantly overestimates electric driving. Ministers say the practical approach is to let drivers choose hybrids, and that PHEV emissions remain 40% below the average petrol or diesel car. The industry argues those two statements are not easy to hold together at once.
With a consultation on the zero emission vehicle mandate closing in October, and Nissan this week hinting it could withhold a £170m Sunderland investment if targets move the wrong way, the charging capability of Britain’s favourite hybrids just became a much bigger deal than a spec-sheet footnote.
