The DBX has... a ducktail?

There’s no chance this serves an aero purpose, right?

“Fixed rear spoiler ensures both aerodynamic and aesthetic look of rear”

Aerodynamics were an important consideration within the design process and this included the novel experience for the team of running computational fluid dynamics (CFD) tests with a DBX towing a trailer with a DB6 on it. At the car’s front, the daytime running lights (DRLs) have an integrated aerodynamic duct, which channels air through the front wheel arches and along the side, helping to reduce both drag and lift while also cooling the brakes. Air flows cleanly over the roof, through the rear wing, over the rear window and on to the rear flip. This unique approach and design detail allows the rear screen to self-clear on the move.
