In addition, Ford Fiesta ranks as the fourth best-selling vehicle, making Ford the only brand to have two nameplates among the global top five bestsellers, according to Ford analysis of Polk global vehicle registration data.
Ford Focus grew 20% in the first half of 2013 from the same period last year, to 589,709 vehicle registrations, driven primarily by increasing demand from customers in China and other Asian countries.
Focus in China is up 137% from 2012, to a total of 202,380 vehicles.
"Fiesta is off to a terrific start, and Focus just keeps getting better – especially in China," said Jim Farley, Ford Executive Vice President, Global Marketing, Sales and Service and Lincoln.
"This is One Ford at its best: great-looking vehicles with great fuel economy, leading quality, technology and fun-to-drive personalities."
