Auto sales dip month-on-month in April due to rise in Covid-19 cases: SIAM SECTIONS Share Synopsis As per data available with industry body Society of Indian Automobile Manufacturers (SIAM), passenger vehicle sales last month stood at 261,633 units, two-wheeler sales at 995,097 units and three-wheeler sales at 13,728 units. The data does not include volumes of Tata Motors, which has stopped reporting monthly sales to SIAM. Sales of passenger vehicles fell by 10.07 %, compared to March 2021, due to various restrictions in states which have been experiencing surge in COVID-19 cases, said Rajesh Menon, Director General, SIAM. Automobile sales declined in double-digits over March last month, mainly due to the restrictions imposed by local administrations to contain the sharp rise in Covid-19 cases in the country. The industry had recorded zero sales in the same period last year amid a nationwide lockdown.
