Mercedes-Benz India has overtaken rival BMW by posting higher sales in the January-April 2010 period. According to the Society of Indian Automobile Manufacturers (SIAM), Mercedes sold 1,644 units in the first four months of 2010, compared to BMW’s 1,621 units. In calendar-year 2009, BMW had for the first time dethroned Mercedes as the leading luxury-car company in India, by selling 3,619 units as against the latter’s 3,247 units. However, Mercedes-Benz CEO Wilfried Aulbur had said that the company was not worried as its lower sales were attributable to the limited availability of its high-selling model, the E-Class, whose demand exceeded supply by over 300 units.
