Ford Focus 1.0 Ecoboost engine details

The Ford Focus will get a new 1.0-litre Ecoboost petrol engine in the spring with almost as much power as a 2.0-litre unit from 12 years ago.

The 1.0 Ecoboost engine produces 123bhp, with an average economy of 56.5mpg and CO2 emissions of 114g/km. The 2.0-litre petrol engine in the Mk1 Focus from 1999 produced 128bhp, but could average only 33mpg.

Ecoboost technology is already used on 1.6- and 2.0-litre petrol engines in larger Fords, but this 1.0-litre unit will appear in the C-Max and Grand C-Max, as well as the new B-Max MPV when it goes on sale in mid-2012.

A 99bhp 1.0-litre Ecoboost unit is also due to join the Ford line-up next year, with CO2 emissions of 109g/km.
