Audi AG reaffirmed its full-year forecast for a rise in revenue and earnings that reflects an increase in sales to a record 1 million vehicles, it said on Wednesday.

Turnover in the first nine months gained 2.1 percent to 25.80 billion euros ($32.88 billion), while operating profit grew by 13.6 percent to 2.06 billion, the company reported in its quarterly update.

The company stuck to its target of selling 1 million Audi brand vehicles this year, with a corresponding rise in sales and earnings.

In 2007, the Ingolstadt-based carmaker sold 964,151 vehicles, generated some 33.6 billion euros in revenue and posted an operating profit of nearly 2.71 billion.

Audi said that the continued instability in refinancing markets posed a general risk, particularly for sales financing.

'The Audi group profits in this situation however from the overall solid liquidity position and conservative refinancing policy of the Volkswagen group,' it said in its update.

Audi clearly outperformed its larger luxury rival Mercedes-Benz Cars of Daimler, which was forced to lower its profit forecast for a second straight quarter last week on impairment losses at its U.S. leasing business. BMW, the world's largest luxury maker by volume, is said to make announcement that it too will not be able to meet its profit forecast.

Earnings before interest and taxes at Mercedes fell 26 percent to 2.48 billion in the first nine months, and it now expects full year margins to fall to about 5 percent due to charges of 449 million euros related to falling prices of cars coming off lease.
