Ford introduces greenest ever petrol engine in Focus

Ford’s EcoBoost petrol engine range, designed and built in the UK, will now include a three cylinder, 1.0-litre engine for the Ford Focus.

However, concerns about the use of such a small engine in the best-selling small family car have been allayed by the car maker after it revealed it would be as powerful as a 1.6-litre petrol engine.

The new EcoBoost unit will deliver sub-120g/km of CO2 emissions in the Focus, the lowest level ever offered by a petrol engine.

It will mean the Ford Focus will be eligible for Band B of road tax for the first time as a petrol model, making it eligible for free first year road tax in the UK.

The turbocharged engine delivers 100PS or 120PS depending on the variant chosen, but both make use of fuel-saving technology to reduce CO2 emissions and improve fuel economy.

Technology such as Auto-Start-Stop technology, designed to switch the engine off automatically when the car is stationary for short periods of time, Active Grille Shutter to reduce drag and regenerative charging to top up the battery are all included in the EcoBoost package.

Graham Hoare, Executive Director, Powertrain, Ford of Europe, said: “The 1.0-litre EcoBoost is one of the most advanced engines Ford has ever produced and makes use of so many innovative techniques and technologies that it’s difficult to keep count.”

Surprisingly for such a small engine, the 1.0-litre EcoBoost will also be used in the new Ford C-Max from 2012, the five-seat MPV launched towards the end of last year. It will also appear in the more compact Ford B-Max people carrier when it goes on sale.

The new Ford Focus with 1.0-litre EcoBoost engine will be launched in the UK in 2012. Prices for the EcoBoost models will be announced closer to launch date.
