Mark Simpson, marketing director, Ford of Britain, said: "Dealers are telling us that people are coming out of their Peugeot 207s and Renault Clios to get into new Fiesta.
"We expect to attract even more sales from business and economy-minded drivers next year when our Econetic model goes on sale."
