A Ford Fiesta ECOnetic has clocked an incredible 108.78mpg to win the ALD Automotive/Shell FuelSave MPG Marathon.
The completely unmodified, 1.6 TDCi covered 370 miles of real world conditions in the hands of former rally stars Andy Dawson and Andrew Marriott.
Taking the Fiesta round the economy run was a slightly different challenge to the one these rally drivers are used to but a challenge none the less.
They beat strong competition in the form of a Kia Rio 1.1 litre which achieved 102.2mpg, the first car to ever break the 100mpg mark at the MPG Marathon.
But somehow the 1.6 litre Ford eclipsed this achievement and put itself at the top of the fuel economy stack.
The return of 108.78mpg is 23 miles more than the official figure of 85.6mpg that Ford quote for the Fiesta ECOnetic.
The MPG Marathon, organised by fleet trade magazine Fleet World, is made to be a 'real world' test and aims to show how smarter driving can benefit economy.
