Audi has started testing the upcoming Q4 SUV on public roads, with the BMW X2 rival making its spy debut.

The spyshots themselves are edited with new backgrounds in order to not reveal the location of the shoot.

Previously referred to as the TT SUV of the German brand, the new Q4 will be based on the same MQB platform as used in the latest Q3.

The new SUV will adopt its own, more dynamic exterior design that will mix elements from both the Q3 and the larger Q8. A lower roofline combined with higher shoulders are the key differences, along with a front end that’s looks slightly more aggressive than the Q3.

Last month, Audi’s exterior design chief said that the Q4 will be “a bit more than a coupe version of the Q3”, without providing further details.

The final production model is expected to measure at least 4,500mm long (177.1 inches), which will make the Q4 marginally longer than the Q3. Despite the lower roofline, cabin space is expected to be more generous than that of its closest rivals.

The engine range will share some -if not all- of the powertrains currently on offer with the Audi Q3, meaning a wide range of turbocharged petrol and diesel engines. Quattro all-wheel drive will be offered in the most powerful models, including a rumored RS Q4 model with a five-cylinder 400hp powerplant.

Audi previewed its intentions to enter the compact SUV Coupe class with the 2014 TT Offroad concept. The final production version of the Audi Q4 is expected to debut sometime next year.
