M&M Chief Executive (Automotive Division) Pravin Shah said: "It is unfortunate that the auto industry has not seen an upturn over the last couple of months in spite of a reduction in excise duty."
The company expects that post the general elections, sentiments would improve, leading to a better economic situation and hence increased demand, he added.
"At Mahindra, we are happy with our exports performance for the month and we continue to be optimistic going forward and expect to witness a gradual upswing on the back of our product offerings and customer centric initiatives," Shah said.
