German-owned British luxury carmaker Bentley said Tuesday that its sales surged last year on the back of strong performances in China and the United States, the world\'s two biggest auto markets. Total sales soared 37 percent to 7,003 vehicles last year, said Volkswagen\'s upmarket British-based division in a results statement. Bentley, which is headquartered in Crewe, northwestern England, said sales rocketed by 69 percent in December alone to 1,059 cars, compared with the same month in 2010. The United States remained the group\'s number one market with a total of 2,021 car sales in 2011 -- 32 percent higher than in 2010. But demand was also particularly strong in China, where sales almost doubled to a record 1,839 -- making it the company\'s second-largest market. Sales in continental Europe increased 53 percent to 1,187 vehicles led by strong demand in Germany where sales jumped 88 percent. In domestic market Britain, where the company said conditions were particularly challenging, Bentley sold 1,031 cars in 2011, up five percent. \"It has been a tremendously good year for Bentley,\" Bentley\'s chairman and chief executive Wolfgang Durheimer said. \"The dramatic sales growth reflects a global strength to the brand and a recognition of the quality, craftsmanship and engineering excellence of our cars,\" he said.
