Plug-in hybrid cars ‘costing £500 a year more to refuel than lab tests suggest’

Analysis of real-world data suggests annual cost of fuelling PHEVs is nearly double manufacturers’ claims

Drivers of bestselling plug-in hybrid cars pay £500 a year more on fuel for their cars than manufacturers’ figures suggest, according to analysis of real-world data, largely because owners tend to charge them less frequently than expected.

Laboratory tests of plug-in hybrid electric vehicles (PHEVs) suggest that fuel should cost £560 a year, but real-life data suggests the cost is nearly double that, at £1,059 a year, according to analysis by the Energy and Climate Intelligence Unit (ECIU), a climate research group.
