The car uses the Volkswagen Group A5 (PQ35) platform of the Volkswagen Golf Mk5, the same as the Volkswagen Tiguan compact SUV. The Q3 slots above the Audi Q2 subcompact crossover SUV. Compared to the compact luxury crossover SUV Q5 and mid-size luxury crossover SUV Q7, which are positioned more for family practicality and off-road performance, the Q3 is aimed as more of a lifestyle/sports automobile. Design and development began following board approval in the second half of 2007. Julian Hoenig's design was chosen for production and frozen in 2009.
