Tata Motors reported a strong start to FY27 in its passenger vehicle business, with total sales rising 46% year-on-year in the June quarter, driven by robust demand for its new launches and continued strength in electric vehicles.The company sold 1,82,574 passenger vehicles across domestic and international markets during the April-June quarter, compared with 1,24,809 units in the year-ago period. Domestic passenger vehicle sales rose 45% to 1,80,166 units, while international business volumes climbed 148% to 2,408 units.June also proved to be a strong month for the automaker. Total passenger vehicle sales rose 69% year-on-year to 63,083 units, while electric vehicle (EV) sales surged 183% to 14,800 units, marking the company's highest-ever monthly EV sales.For the quarter, Tata Motors sold 34,467 EVs, more than double the 16,231 units sold in the corresponding period last year.Managing Director and CEO Shailesh Chandra said the company delivered industry-beating growth during the quarter, supported by strong customer demand and the success of recent product launches. He said Vahan registrations increased by around 40% year-on-year, nearly twice the industry's growth rate.The company said the updated Tiago and Punch models received strong customer response across powertrain options, while demand for electric vehicles continued to strengthen across segments.Tata Motors, however, said supply constraints affected deliveries of the Sierra during the quarter. The company said it is working with vendors to increase production capacity and expects deliveries to improve from the second quarter.While the domestic passenger vehicle business reported strong growth, its luxury vehicle arm Jaguar Land Rover (JLR) had a weaker quarter due to temporary disruptions.JLR reported wholesale sales of 79,300 units in the June quarter, down 9.2% from a year earlier. Retail sales fell 15.3% to 80,000 units.The company attributed the decline to a fire at a major component supplier at the start of the quarter, disruption caused by the conflict in the Middle East, and the planned phase-out of existing Jaguar models ahead of the launch of the new Jaguar Type 01.Wholesale volumes declined across most regions, including China, Europe and the UK, although sales in the Middle East and North Africa region increased slightly while North America remained largely flat.Despite lower volumes, JLR said its premium product mix remained strong. The Range Rover, Range Rover Sport and Defender together accounted for 80.8% of wholesale sales during the quarter, up from 77.2% a year ago.JLR will announce its financial results for the June quarter in August.
