The August performance was also driven by strong sales of the Land Rover Discovery Sport, the Jaguar XE and the F-PACE, as well as rising sales in the US where the firm sold 372,978 vehicles in the first eight months of 2016, up 24% from the same period last year.
Retail sales across both North America and Europe have increased 45% and 37% respectively compared to the previous year, as well as a 36% boost in China.
Land Rover's latest luxury convertible SUV, which is designed, engineered, and manufactured in the UK, has seen promising results since its start of sales, with more than 1,200 vehicles sold worldwide.
Andy Goss, Jaguar Land Rover group sales operations director said: "We continue to grow our sales, with impressive performances across both of our brands. Sales in North America were particularly strong, where we sold over 10,000 vehicles in August alone.
"The Evoque Convertible has performed well in its first few months of sales and will play a key role in continuing Range Rover's 45-year success story."
