Global sales of Jaguar cars rose 63 percent to 7,061 last month, helping to offset a 6 percent fall to 24,149 in the sales of Land Rover vehicles.
Combined sales at the British Jaguar Land Rover brand unit, which India's Tata Motors purchased for $2.3 billion in 2008, stood at 31,210 in the month, a rise of 4 percent from a year ago, Tata said on Sunday.
Sales at Jaguar were boosted by the European launch in May of the F-Type convertible, the brand's first two-seat sports car in almost four decades.
Speaking at the end of last month, the carmaker's global brand director Adrian Hallmark said half of 2013's production had already been sold and customers ordering now would be lucky to receive their cars this year.
Sales of the model in the United States will begin next month.
Jaguar expects the F-Type will account for 15 percent to 20 percent of the brand's total annual production of about 60,000 units.
Tata global sales
Tata's global wholesale vehicle sales fell an annual 18 percent in May, the company said, as the marginal rise in the sales of Jaguar Land Rover cars failed to offset sluggish passenger and commercial vehicle deliveries.
Tata Motors, part of India's salt-to-steel Tata Group conglomerate, sold 81,783 vehicles in May, the company said in a statement on Sunday. Passenger cars accounted for 43,142 vehicle sales, down 16 percent from a year ago.
