Tata Motors' Jaguar Land Rover retail sales in May 2019 fell 12.2% year on year to 42,370 vehicles worldwide.
Higher retail sales of the recently redesigned Range Rover Evoque and I-Pace EV were offset by lower sales of other models, primarily in China.
Sales of the Discovery Sport were lower ahead of the introduction of the refreshed model which is now on sale following its launch in May.
As we reported earlier this month, Land Rover set a new May sales record in the US but Jaguar dragged the company's results and left it with a deficit.
By region, retail sales were down in North America (-1.5%) and also in other markets including the UK (-6.7%), Europe (-9.6%), 'overseas markets' (-18.4%) and China (-26.4%) where market conditions remain challenging.
Jaguar retail sales in May 2019 fell 9.4% to 13,142 vehicles and Land Rover volume was off 13.5% to 29,228 units.
Felix Brautigam, Jaguar Land Rover chief commercial officer, said: "May saw two important milestones for Land Rover with the debut of significant model updates.
The brand's best-selling Discovery Sport premium compact SUV has been transformed from the ground up, making it almost a new car. Featuring the all-new Premium Transverse Architecture, it will be available with MHEV (mild hybrid electric) and PHEV (plug in hybrid electric) powertrains which are important additions to our growing portfolio of electrified vehicles.
"The enhanced interior of the new Discovery Sport is highly versatile, available with seven seats and featuring the latest connectivity.
"The latest Range Rover, which was also revealed in May, comes with a range of upgrades. These include our new three-litre straight six Ingenium petrol engine with a mild hybrid electric system, as well as the innovative combination of supercharging and turbocharging technologies."
"Although sales dipped at Jaguar this month, we were pleased to see the continued strong response to the award-winning I-Pace.
"We also launched the E-Pace Chequered Flag edition which generated a high level of interest with customers and commentators alike."
Jaguar Land Rover calendar year to date retail sales were down 9.7% to 240,471 vehicles.
