Prince Charles has converted his vintage Aston Martin DB6 to run on bioethanol distilled from surplus British wine.
Eco-friendly Charles was given the Aston by the Queen on his 21st birthday. It only clocks up 300 miles per year and averages ten miles a gallon - that’s roughly five bottles of wine per mile.
The biofuel costs £1.10 a litre, but its net output of CO2 is considerably less than normal petrol as the gas is absorbed during the growing process of the vines.
A wine surplus exists because vineyard owners can’t bottle more than their EU quota, so they sell it to Green Fuels of Gloucester to convert to bioethanol.
Converting the Aston is just one of a raft of measures that Prince Charles is taking in an effort to reduce the Royal Family’s carbon footprint.
