The recent upturn in the US economy appears to have spurred car sales.

Reports from the major manufacturers show November was a healthy month for the auto sector. It was particularly good for General Motors, whose sales jumped 22% year-on-year, and Toyota Motor, up 12.7%.

Sales at Chrysler Group also rose in November, but by a less impressive 3%. The smallest of the 'big three' Detroit manufacturers responded by announcing a major incentives and promotion effort at the end of the year. It revealed it would spend more on this campaign than it did on its summer marketing push, which had an estimated budget of $100 million (€83m; £58m).

Elsewhere, Ford Motor Company and Mercedes-Benz reported respective sales declines of 2% and 6%, and there were healthy upturns for Volkswagen (+27.6%) and BMW (+6.4%).
