Jaguar Land Rover retail sales fell 15.3% year-on-year to 80,000 units in the first quarter of fiscal year 2027 as it grapples with supply constraints and softening demand, parent India's Tata Motors Passenger Vehicles said on Thursday. The British luxury carmaker sold 79,300 units wholesale in the first quarter, a 9.2% decline from a year earlier. A fire at a key component supplier temporarily squeezed supply during the reported quarter, the company said.
