We successfully upgraded the entire vehicle portfolio during BS6 Phase 2 transition, beyond the mandatory requirements, to offer more features, value-adds and benefits to customers. M&HCV growth was driven by the strong infrastructure push by the Government, as well as increased activity in e-commerce, construction, and replacement demand in auto logistics and petroleum sector. During the quarter, we started deliveries of Electric Buses, in accordance with the CESL tender mandate and expect to ramp up supplies in the coming months. Looking ahead, the promising monsoon and continuing infrastructure thrust by the Government auger well for the CV industry, even as it faces the headwinds of high interest rates, fuel prices and inflation.”

While SUVs continued to be the mainstay, contributing almost 64% of the sales in Q1FY24, car sales remained strong, buoyed by the multi-power train offerings of Tiago and Altroz. The recently launched Altroz iCNG, has received much acclaim and excellent response from customers.

In the EV segment, the company posted its highest ever quarterly sales of 19,346 in Q1 FY24 registering a growth of ~105% over Q1 FY23. This growth is driven by a strong market response to Tiago EV while demand for other EVs was sustained.
