Ford has announced a new ultra-efficient version of the Focus 1.0-litre EcoBoost that will be the first petrol-powered family car in Europe to offer 99g/km CO2 emissions.

The Focus 1.0-litre EcoBoost has returned 67.5mpg in tests thanks to its specially calibrated 100PS version of Ford’s award-winning engine.

The new Ford Focus will feature Ford ECOnetic Technology including ultra-low rolling resistance tyres, unique aerodynamics under the car and revised gearing to help deliver the company’s most fuel-efficient ever petrol-powered family car.

The International Engine of the Year 2013 and 2012 makes the new model more powerful than a first generation Ford Focus with a 1.6-litre engine from less than 10 years ago, while producing 47 per cent less CO2.

The new model will extend to three the number of Focus models offered with the 1.0-litre EcoBoost engine, alongside the standard 100PS version, with 109g/km CO2 emissions, and the 125PS with 114g/km CO2.

Introduced to the Fiesta, B-MAX, C-MAX and seven-seat Grand C-MAX last year, the 1.0-litre EcoBoost engine will be extended to the EcoSport SUV, Transit Connect and Transit Courier commercial vehicles; Tourneo Connect people mover; and later the all-new Mondeo.

Ford is also currently launching the zero emissions Focus Electric, and also offers the diesel Focus ECOnetic that delivers 88g CO2 emissions.
