The car was said to feature "one of the most extreme rear diffusers seen" and also a ride height adjustment system.

A front splitter and rear diffuser further improve vehicle aerodynamics.

Injecting the exhaust into the rear diffuser can also help extract the air from below the car.

The closer the car is to the ground, the more efficient the front wing and rear diffuser.

Audi has also introduced a new rear diffuser that appears to be more cosmetic than the one found on previous models.

Yet the car had one difference, which was focused on the rear so-called 'double-decker diffuser'.

To complete the aerodynamic body, the bottom of the car is flat all the way from the front to the rear diffuser.

The rear diffuser is revised to meet the regulations that stated it has to produce less downforce.

Sutil's car suffered damage to the rear diffuser, and he was forced to retire.

Under the body, panels and air fences in the front, along with a small rear diffuser, produced balanced downforce.
