FORD has added electrification to the Fiesta for the first time, giving the best-seller a mild-hybrid system.
Using a 48-volt motor to assist the petrol engine, Ford claims fuel efficiency is improved by 5 per cent while also making it more powerful and responsive to drive.
For this powertrain, the traditional alternator is replaced with a belt-driven starter generator, which enables recovery of energy usually lost during braking and coasting.
This energy can then be redeployed to boost the engine under acceleration or take over running the vehicle's electrical ancillaries.
It is available in two power outputs of 123bhp and 153bhp. The former emits 109g/km CO2 and promises 57.6mpg, while the latter emits 116g/km CO2 and achieves 55.4mpg.
It's part of Ford's plan to offer an electrified version of every passenger vehicle it makes and plans to have 18 electrified models on sale by the end of 2021.
Roelant de Waard, vice president of marketing, sales and service at Ford of Europe, said: "Adding EcoBoost Hybrid technology to Fiesta's best-in-class driving dynamics means customers can have even more power and still go further on a tank of fuel.
"The Fiesta EcoBoost Hybrid will help Ford bring the benefits of electrification to more drivers than ever before."
The mild-hybrid Fiesta will be available on the Titanium trim level with prices starting just under £20k.
Equipment on this model includes adaptive cruise control with stop and go and speed sign recognition.
