Audi has been working the generation upgrades for its entire line up and while last year we saw the new-gen models of the Q5 SUV and the A8 sedan. This year, however, we are expecting the next-gen Audi Q3 to make its global debut, possibly towards the end of 2018. Recently a prototype of new-gen Audi Q3 was spotted undergoing cold weather testing and while most of the car was heavily camouflaged, we were able to notice the stylish LED taillamps and LED headlamps, which look like they are final production units.
