Tata bought Jaguar Land Rover from Ford in 2008
Jaguar Land Rover had seen its sales rise 23% in the second quarter after its new models were well-received.
Owner Tata Motors said new products such as the upgraded Range Rover, Range Rover Sport and Discovery 4 had had successful launches.
Although Jaguar Land Rover made a net loss of £60m in the July-September quarter, it was much less than the £240m loss it made a year earlier.
India's Tata Motors made a net profit of 217.8m rupees ($4.7m; £2.8m)
That compared with a loss of 9.4bn rupees a year earlier.
Tata said Jaguar Land Rover's performance was the highlight of the quarter.
Tata bought the British marques from Ford for £1.7bn in June 2008.
Sales volumes at Jaguar Land Rover rose to 44,300 vehicles from 35,900 in the previous quarter.
Aggressive cost reduction had also paid off, Tata said.
"The [Jaguar Land Rover] business is witnessing some stability in the external environment with certain key markets showing signs of recovery," Tata said in a statement.
