The new Econetic Fiesta delivers a combined fuel consumption of 85.6mpg with CO2 emissions at just 87g/km.
This is enough to qualify for zero Vehicle Excise Duty (VED) in the UK and the high fuel economy ensures Ford drivers will be cushioned from recent budget fuel duty increases.
The line-up retains a 93bhp 1.6-litre diesel engine as well as its five-speed manual transmission. As before this powertrain is available with three and five-door models of the Fiesta and applies to three trim levels including Edge, Zetec and Titanium.
However while the set up remains the same, Ford’s engineers have fine tuned the engine in order to improve efficiency.
As a result the Fiesta Econetic’s combined fuel economy has been improved by about 7mpg from the previous figure of 78mpg and CO2 emissions have been cut by 8g/km from the previous total of 95g/km.
These numbers mean that owners of the new Ford Fiesta Econetic benefit from free road tax and exemption from the London Congestion Charge.
The Econetic range can also be found with the Ford Focus hatchback, which returns 83.1mpg and emits 88g/km in CO2. The specification also applies to the Ford Mondeo saloon and estate, which records 65.6mpg and 114g/km in CO2 emissions.
Prices for the 2012 Ford Fiesta Econetic range start from £14,095 for the Edge trim, increasing to £14,645 for the Zetec model and £15,845 for the Titanium trim. They are available from Ford UK dealerships.
