The Guardian view on hybrid cars: profitable for carmakers but not very green | Editorial

Plug-in hybrids pollute more than their manufacturers claim – and delay the real shift to electric and shared mobility“Why the future is hybrid,” chirruped the Economist in 2004. While electric vehicles (EVs) looked like science fiction, that prediction looked prescient. Fast‑forward 20 years and battery technology has improved dramatically; EVs are affordable. Last week it emerged that plug-in hybrid electric vehicles (PHEVs) aren’t very green. The sales pitch had been that motorists could use “clean” battery power for city jaunts and dirty petrol for longer trips. This promised sustainable travel without the anxiety of a limited range. But real‑world tests, by the European non-profit Transport and Environment, show that PHEVs emit just 19% less carbon dioxide than petrol and diesel cars – far short of the 75% claimed in the lab.Hybrid vehicles are, however, very profitable. Carmakers can charge top dollar for what are essentially re-engineered petrol cars with a battery bolted on. They also remain attractive to policymakers keen for industry sops. By weakening electric vehicle targets, the UK government risks a scandal in pushing hybrids that emit five times more CO2 than claimed. Continue reading...
