For the second year in a row, Ford has claimed the title of selling world's most popular car.

The Focus, which has become a big hit in China, was the world's best-selling car in 2013 according to Ford's analysis of registration data compiled by Polk, a division of IHS Automotive.

Last year, Ford sold 1,097,618 Focus models around the world, an 8.1 percent on-year increase.

To give you some perspective on the popularity of the small sedan, Ford sold more than two Focus cars every minute of every day last year.

China driving focus demand

The Focus has become the top selling car in the world over the last two years due to explosive demand in China.

Last year, Focus sales in China increased by 50 percent to total 403,219.

The small car is a big reason why Ford sales in the world's largest auto market are expected to top 1 million this year.

Ford's monthly sales in China topped 100,000 for the first time in March.

Common platforms driving profits

Ford's worldwide success with the Focus is validation of the blueprint CEO Alan Mulally created for the revival of the automaker when he took over the company eight years ago.

At the time, Ford had 27 different vehicle platforms around the world building 6.8 million vehicles.

Under Mulally, Ford has consolidated the number of platforms down to 15 with annual sales totaling 6.3 million.

As Ford has shrunk the number of platforms, it has increased the use of common parts, cut costs and raised profits.

Last year, Ford posted a pre-tax profit of $8.6 Billion.
