Britain’s best-selling car, the Ford Fiesta, is expected to feature a sub-120g/km 1.0-litre Ecoboost engine when a facelifted version goes on sale in December.
The highly impressive turbocharged three-cylinder unit — one of Autocar’s favourite engines and already fitted to the Focus — will save owners at least 10g/km in CO2 emissions compared with the four-pot petrols that power today’s Fiesta.
That will bring savings in VED tax and fuel economy, but the engine will also add a lively driving style and pleasantly thrumming three-pot engine note to the Fiesta.
The 1.0 Ecoboost is just one example of a significantly revamped Fiesta engine range based on the powerplants recently announced for the Fiesta-based B-Max mini-MPV.
Also on the cards for the revised Fiesta are a 73bhp 1.5 TDCi and a 93bhp 1.6 TDCi, tipped to replace the 1.4 TDCi. These engines will bring more power and slightly better CO2 emissions to diesel Fiestas.
There will also be styling changes, which incorporate the new grille and headlamps seen on the Fiesta ST.
