FRANKFURT -- BMW increased sales by 11.4 percent to 131,705 vehicles in September thanks to robust demand at its core BMW brand, it said on Friday.
In the first nine months, group deliveries to customers totaled 988,463 units, also a gain of 11.4 percent.
BMW Chief Executive Helmut Panke had told reporters during the Frankfurt auto show last month that he expected group vehicle sales to climb by 9 percent this year to a new record level.
Sales of BMW brand cars and SUVs rose 13.5 percent last month to 111,518 units, while Mini brand sales managed only a 1.0 percent increase to 20,112 cars.
Growth again was driven by the success of BMW's new 1-series compact hatchback, first launched in September 2004. Through the first nine months, 114,188 units were delivered to customers.
Since group vehicle sales year-to-date would have declined were it not for the launch of the 1 series, this signals weakening figures for the carmaker's other products.
Nevertheless, BMW said demand for its three core model lines remained strong relative to the industry.
The 3 series, 5 series and 7 series are all best-sellers in their own segments, it said.
Volkswagen's premium brand Audi -- a key competitor of BMW -- reported on Wednesday an 11.9 percent increase in unit sales last month.
