when does q3 start

If you're asking about the Audi Q3, it first hit the Australian market in 2011. The latest generation, which really cleans up the act, launched here around 2018. Now, if you meant Q3 as in the third quarter of the year, that starts on July 1 and runs through to September 30. So, clarify your Q3 quandary next time, but that should get you sorted.
