After 18 months on the market in every country outside of North America, an impressive 340,000 variations of Chevrolet's Cruze sedan have been delivered.

Chevrolet's upcoming Cruze sedan represents a major leap forward for the Detroit automaker in the compact car segment currently occupied by the dated Cobalt. Until it goes on sale later this year, however, the automaker's core North American market has been denied the crucial sedan that has sold more than 340,000 units everywhere but at home.

GM announced this morning that it has sold 270,000 Chevrolet Cruze-badged sedans across the globe and an additional 70,000 Holden and Daewoo-badged variants in Australia and South Korea.

"Customers around the world have already made Cruze an international success, setting the stage for it here in the U.S.," said Margaret Brooks, the automaker's director of marketing for Chevrolet small cars, in a statement released to the media.

GM has never really clarified why the Cruze has taken so long to go on sale in North America. Sales are finally set to begin in September, about 18 months after the car debuted in Europe.
