The Ford Fiesta supermini was the most efficient car on the 370-mile event, which ranks cars in terms of their fuel economy instead of any finishing times.
And, despite driving in challenging weather and across a variety of different roads, a Ford Fiesta Econetic using a 1.6-litre diesel engine recorded average fuel economy of 108.78mpg over the trip.
This is well above the car’s official fuel consumption figure of 85.6mpg thanks to the frugal driving of former rally drivers Andrew Marriott and Andy Dawson.
The 100mpg milestone has not been achieved at the MPG Marathon in the past with a number of Smart cars falling just short in previous years.
Event organiser Ross Durkin commented: “This year’s MPG Marathon will be remembered for the two teams who beat the elusive 100mpg barrier – both superb performances.
“The average improvement over combined cycle figures achieved by the 27 vehicles in this year’s event was a whisker under 16 per cent – impressive by anyone’s standards.
“Manufacturers have done a tremendous job in improving the fuel efficiency of all news cars and vans, but motorists should see their published fuel consumption figures as a target to beat, not the maximum achievable.”
The Ford Fiesta fitted with the 1.6-litre engine is the most frugal car in the Fiesta range and delivers 87g/km of CO2 emissions – enough to qualify for free UK road tax.
The Ford Fiesta is the UK’s most popular car, topping the sales charts in 2011 and in 2012 to-date.
