BMW Sauber F1.06 - rear-end detail 20 January 2006
As on all the 2006 machines, the sidepods are smaller and narrower, particularly as they reach the 'coke-bottle' section at the rear of the car (red arrow), where the bodywork looks like a second skin applied to its internal elements. This minimal design is intended to smooth the airflow to the rear diffuser. Hidden by shields at the car's launch, the F1.06's diffuser looks very similar to that of the previous Sauber C24 in its side sections, sporting a small flip-up right in front of the rear wheels, hiding within it two heat sensors, and sporting a small, vertical fin just inside the wheel.
