September quarter sales volume at JLR rose 23 per cent to 44,300 vehicles from 35,900 in the preceding quarter, and Tata Motors said there were signs of improved demand for other key units after a global slump in the auto sector. New JLR products such as the upgraded Land Rover, Range Rover Sports and Discovery 4 were getting a good reception and aggressive cost cuts were also paying off, Tata Motors said. "Many of the cost reductions underway at Jaguar and Land Rover should benefit us in the coming quarters," said Chief Financial Officer R. Ramakrishnan.
