A three-wheeled car built by a Bath- based engineer has travelled 6,603 miles on a gallon of fuel.
The eco-friendly car may prove to be the transport of the future
Andy Green, of the University of Bath, who built the vehicle, competes in competitions to find the world's most fuel-economic car.
The Team Green car set a new British record at the Alford race track in Scotland, beating the old record, achieved in 1999, by more than 200 mpg.
"We are delighted to break the record," said Mr Green.
"Our next target is taking on the most fuel-economic cars in Europe and beyond."
Competition judges measure the fuel capacity of the car and then see how far it travels on one tank of petrol.
For its record-breaking run, the car was driven by Jenny Goodman, a graduate Aerospace Engineer, also from Bath University.
The car had to be driven between speeds of nine and 13mph.
