It is clear to see a curved sharp edged line that starts at the very front, flowing through the middle section, slightly curved down after the A pillar and then going back up again at the rear wheel arches to follow its way back until the diffuser. This same curve language is also applied to the greenhouse and the way windows are shaped. The front is somehow aggressive looking with the traditional AUDI grill and air intakes that are shaped very much like the headlights to create a coherent feeling.
The rear section is obviously very organic with defined curves and subtle details, tail lights are designed to have integrated air outtakes underneath them to avoid any unnecessary details. With dual exhaust and fairly empty rear section, it creates a feeling of subtleness. Another feature is the air intake at the end of the roof which is designed to avoid any distracting design elements on the top of the car combining elegance with functionality.
