Some of the most popular family cars will be unable to use a new fuel the government hopes to roll out in an effort to cut carbon emissions.
Hundreds of thousands of vehicles including Volkswagen, Ford and Nissan models, are not compatible with E10 petrol, which has already been introduced across the EU,US and Australia.
E10 is considered a greener alternative fuel as it is made up of 10% bioethanol, rather than 5% found in regular petrol. The Department for Transport launched a consultation last month on its proposal to encourage larger forecourts to sell E10 to help the UK to meet climate change targets. New analysis by motoring research charity the RAC Foundation shows that many cars still in regular use are incompatible with the new fuel.
