Also, if no-one's seen it yet, this car actually does have a step-nose but it has side rails to sort of hide it from view. On another note, the sidepods are dramatically different from last years (almost Red Bull-ish). please log in to view this image
They've said it will build on the strengths of last year's car, which means I presume once again they'll go easy on the tyres but struggle for outright pace the vast majority of the time.
Interesting: Tobias Grüner F1 ‏@tgruener #F1 Sauber #C32 sidepod trick not revealed in detail. Some parts around missing. Matt Morris: "You will see our idea behind that soon."
Slim sidepods apparently inspired by Perez's crash. http://www.autosport.com/news/report.php/id/105375
please log in to view this image In Malaysia Sauber have modified the back of the C32's engine cover with an oval opening similar to that on the Red Bull in order to improve extraction of hot air from the engine and from the car's distinctive, narrow sidepods. And in the lower section of the rear bodywork the team have introduced a small, but very long vertical fin to better direct airflow (red arrows) to the back of the car and the side channels of the rear diffuser.
