Ford Focus ST sales have increased by 270 per cent since the introduction of new petrol and diesel powertrains.
Almost 6,700 petrol and diesel Focus STs have been sold in the UK so far this year, compared with 2,460 for the whole of last year.
UK demand is almost split evenly between the two engines, with 45 per cent opting for the new 185bhp diesel, and 55 per cent choosing the 250bhp EcoBoost petrol.
Ford will further expand the Focus ST power-train line-up in early 2016 with the introduction of a six-speed dual-clutch PowerShift transmission available with the diesel engine. Order-books are open now.
Roelant de Waard, Vice President of Marketing, Sales and Service at Ford of Europe, said: "New Focus ST has been a runaway success with customers spoilt for choice between our latest petrol and diesel power units. Diesel drivers now have the additional option of the Ford PowerShift transmission, which allows them to swap between quick-shifting automatic and sporty manual to suit their mood."
