Ford's Budget Day fuel saver - 85 mpg Fiesta

Ford has chosen Budget Day to launch the new version of the Ford Fiesta ECOnetic. It emits just 87g CO2/km – meaning free road tax and no London Congestion Charge – with a combined fuel consumption of 85.6mpg.

If you are wondering if those claims are believable, we did an economy run in the previous Fiesta ECOnetic and managed to slightly better its official figure of 76.3 mpg, by getting 78.2 mpg in a run from Brighton to London. It took a lot of concentration and we would not want to drive like that every day, but it does suggest Fiesta MPG figures are achievable, if you are prepared to put the effort in.
