Most popular brand
Volkswagen continues to be the most popular car brand despite the emissions scandal, with 1,092 new cars licensed last month.
Hyundai was the second-biggest car manufacturer, followed by Ford, Toyota and Skoda.
The top five car brands account for almost half of all private cars licensed.
Some 70 per cent of cars licensed in the first eight months of the year were diesel.
The CSO figures usually differ from those issued by the Society of the Irish Motor Industry (SIMI). The CSO measures the number of cars taxed for the first time while the SIMI figures are based on new registrations issued by the Vehicle Registration Office.
