NEW DELHI: India’s auto trade body has lowered growth estimate for passenger vehicle sales in next fiscal to 11 per cent from earlier 12 per cent, after the government raised taxes on car sales last month. In his annual federal budget, Finance Minister Arun Jaitley imposed a sales levy of up to four per cent on new passenger vehicles aimed at helping fight air pollution and congestion, and a one per cent luxury tax on cars priced over INR one million. The taxes will be a dampener for vehicle sales and there may be retardation in growth, Sugato Sen, deputy director general at Society of Indian Automobile Manufacturers (SIAM), said.
