Ford claims its new Focus EcoBoost, powered by a 1.0-litre three-cylinder petrol engine developing 100PS, is the first petrol-powered family car in Europe to achieve CO2 emissions below 99 g/km.
The new Focus 1.0-litre EcoBoost, with its 67.5mpg combined cycle fuel economy, will go on sale in early 2014.
Ford’s ECOnetic technologies will feature heavily on the new model, with low rolling resistance tyres, revised aerodynamics, and more fuel-efficient gearing, as well as start/stop, regenerative braking, and an active grille shutter.
The EcoBoost engine is already available in the Focus as a 100PS model with 109 g/km emissions, and a more powerful 125PS version emitting 114 g/km.
Also available in the Fiesta, B-Max, C-Max and Grand C-Max, the EcoBoost engine will make an appearance in the forthcoming EcoSport SUV, the new Mondeo and various Transit models.
The diminutive power plant, already the winner of the International Engine of the Year for two years running, uses a low-inertia turbocharger and direct fuel injection to maximise efficiency.
Barb Samardzich, European Product Development vice president, said: “Just a couple of years ago few would have thought that a medium-sized petrol car could break the 100g/km CO2 barrier.”
