The company had sold 6,079 units in the same month of 2012, General Motors India said in a statement.
The sales during May 2013 include 1,506 units of Beat, 2,851 units of Sail, 2,177 units of Enjoy and 1,475 units of Tavera, it added.
"We were able to register the 40% growth only because of the good response to our newly launched vehicles - Chevrolet SAIL and Chevrolet Enjoy," GM India Vice-President P Balendran said.
The company does not expect the market to pick up in the coming months as economic activities have "almost come to a standstill and the market remains completely depressed due to negative sentiments and other structural bottlenecks," he added.
Probably a good monsoon can bring in some cheers to the market, Balendran said.
