New figures from the Central Statistics Office show that a total of 9,781 new private cars were licensed for the first time in August, up 14.1% on the same time last year.
The CSO also said that a total of 6,135 used or imported private cars were licensed, a jump of 67.3% on the same month last year.
Meanwhile, there was also a 24.2% increase in the number of new goods vehicles licensed in August of this year, bringing the total to 2,393.
Today's figures also show that in the first eight months of 2016, seven out of every ten new private cars licensed were diesel.
They also reveal that despite the recent diesel emissions scandal, Volkswagen was the most popular make of new private car licensed in August.
1,092 VWs were sold last month, followed by Hyundai (1,020), Ford (951), Toyota (822) and Skoda (667).
The CSO said that these five makes together represent 46.5% of all new private cars licensed.
In its statement today, the CSO also pointed out that licensing differs from registration in that a vehicle is licensed when a valid motor tax disc is issued for the first time.
Registration occurs when a vehicle gets its registration number for the first time.
