The Hybrid still has air curtain ducts, but a single vent on each side.
Audi is also using the double-vent setup on its forthcoming e-tron S and e-tron Sportback S:

The controlled airflow at the front wheels is fundamental to the aerodynamics concept. The side air inlets in the front – the air curtains – route the air over a channel in the wheel houses to optimize the airflow to the wheels and the vehicle flank. The airflow through the wheel arch trims serves the same purpose: Narrow horizontal bars in the recesses formed by the widened trims in the front channel the airstream to surround and encapsulate disruptive swirl in the wheel houses. The upshot is “cleaner” airflow along the vehicle flank with reduced flow losses. The design of the 20-inch wheels as well as the tread and the pattern on the sidewalls of the tires have also been optimized accordingly.
