1.0 litre EcoBoost engine to power new Ford Focus

Ford’s EcoBoost range of turbo-charged engines is expanding, with a three-cylinder 1.0 litre engine joining the family next month.

Rivalling existing 1.6 litre engines for economy and power, the tiny three cylinder unit will initially power the Ford Focus, before finding a home in the C-Max and new B-Max later in the year.

Power output is an impressive 98 bhp or 118 bhp depending on spec, while economy will be as high as 58.9 mpg. With low fuel usage comes low CO2 emissions, with a figure of just 109 g/km being the lowest in the class for similar engine outputs. The slightly higher emissions of the 118 bhp variant (still just 114 g/km) means road tax will be just £20 or £30 a year depending on model.

Around 200 UK engineers based at Dunton and Dagenham successfully developed the economic and powerful powertrain, whilst also making it compact enough that the cylinder block can fit onto a sheet of A4 paper.

“This is the third addition to our acclaimed EcoBoost engine family,” commented Graham Hoare, European executive powertrain director based at Dunton. “Joining the 1.6-litre and 2.0-litre EcoBoost engines which span 150PS to 240PS, this 1.0-litre EcoBoost signals a new era of downsized, super frugal engines for the sub-130PS segment. During development our UK engineers focused on improving thermal efficiency and reducing friction of the engine’s internal moving parts, especially during warm-up.”

The engine block is cast iron rather than aluminium in order to improve warm up times by 50%, while the flywheel is unbalanced to counteract the natural vibrations a three cylinder engine creates. The engine, despite being designed in Britain, will be built in Germany.

The new Focus range starts at £13,995, while models fitted with the new EcoBoost engine start at £16,245 for the five-door Edge spec, rising to £21,845 for the Titanium-X estate model.
