The introduction of new E10 fuel could increase motorists' fuel consumption by more than 10 per cent. The new fuel, which contains 10 per cent bioethanol, will be rolled out across the UK as part of the government’s commitment to reducing emissions.
But real-world testing by What Car? magazine found that vehicles running on E10 are less efficient than the current E5 (up to five per cent bioethanol) blend of fuel across every engine type tested. This means cars have to use more of the new fuel, costing drivers much more each year.
What Car? tested E10 against pure unleaded using a Dacia Sandero, Hyundai i30, Toyota Prius+ and a Mini Paceman. The Sandero registered a 11.5 per cent drop in economy, while the i30’s consumption increased by 9.8 per cent.
CO2 emissions also increased, although the Low Carbon Vehicle Partnership told What Car? that increases would be partially offset by the renewable properties of bioethanol.
The Society of Motor Manufacturers and Traders said that only 92 per cent of UK cars will run on E10, leaving 1.5 million petrol-powered vehicles at risk of not being able to use the fuel.
