The company had sold 8,901 units in the same month of 2012, General Motors India said in a statement.
"Although we have generated the volumes for Chevrolet Sail as expected, the overall numbers inclusive of other models were not on the expected lines as the market continues to remain subdued," GM India Vice President P Balendran said.
With excise duty also going up for certain categories of vehicles, the market is not expected to improve in the coming months also, as the macro economic uncertainties still continue, he added.
"The hike in excise duty for SUVs which is impacting other models as well has further dampened the growth prospects," Balendran said.
