The Focus 1.0-litre EcoBoost has achieved 67.5mpg in official tests, thanks to further enhancements of the award-winning three-cylinder 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 achieve the impressive figure.

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’s 1.0-litre EcoBoost engine uses a low inertia turbocharger, split cooling system and direct fuel injection to deliver impressive performance from the three-cylinder engine block.

The new Focus 1.0-litre EcoBoost 99 g/km will also use a range of fuel-efficient Ford ECOnetic Technologies including Auto-Start-Stop, Smart Regenerative Charging, Active Grille Shutter and Ford EcoMode to support a more economical and environmentally friendly driving style.
