The company had sold 14,033 units in the same month last year, HCIL said in a statement.
Last month, the company sold 396 units of small car Brio, 2,971 units of premium hatchback Jazz, 2,913 units of compact sedan Amaze and 4,854 units of mid-sized sedan City.
In addition, it exported a total of 350 units during the month under review.
On the sales performance, HCIL President and CEO Yoichiro Ueno said good growth with strong sales numbers was seen across all the models.
"We have increased the WR-V supply for our waiting customers from last month and is reflected in the good numbers posted by the model in July," he added.
On the outlook, Ueno said the post-GST price benefits, healthy monsoon and onset of festive season in many regions from August will give another boost to the sales.
