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

The Focus 1.0-litre EcoBoost, which goes on sale in early 2014, has returned 67.5mpg in tests thanks to its specially calibrated 98bhp engine.

It features Ford ECOnetic technology including ultra-low rolling resistance tyres, aerodynamics under the car and revised gearing.

“Just a couple of years ago few would have thought that a medium-sized petrol car could break the 100g/km CO2  barrier,” said Barb Samardzich, European product development vice president. “Ford’s 1.0-litre EcoBoost engine has a habit of taking expectations of what a petrol engine can deliver and turning them upside down.”

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, while producing 47% 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 98bhp version, with 109g/km CO2 emissions, and the 123bhp 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 new Mondeo.

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