The first C-Max and Grand C-Max models powered by the three cylinder, one-litre EcoBoost petrol engine have been built at Ford's plant in Valencia, Spain.

Both 100PS and 125PS versions achieve claimed best in class fuel efficiency and CO2 emissions.

Fprd Europe's sales and marketing chief Roelant de Waard said: "It's an industry exclusive to power a seven-seat vehicle with an engine this small and we think it will be a revelation for drivers who want fuel economy without sacrificing driving fun."

The C-Max gets 5.1l/100km (55.4 mpg) and emits 117g/km CO2 with either engine while the Grand C-Max achieves 5.2l/100km (54.3 mpg) and 119g/km.

The C-Max line now also will offer SYNC with emergency assistance, various driver assistance technologies, optional power tailgate and a new paint colour called 'burnished glow'.

Ford has sold over 200,000 of the second generation C-Max line which added the seven-seat option.

By 2015, over half of all vehicles Ford produces in Europe for the continent will be powered by EcoBoost engines, which are also available in 1.6- and 2.0-litre forms.
