Its amazing what some dieting in a nice wind tunnel will do. I am not sure if this is also the works of ferrari that we are seeing, but Sauber looks like its ahead of the game so far with this new C24. Look at the sidepods, in addition to the the unusual inlet, look at how low they are at the rear! theyre almost on the same line as the rear axle! and by the end it looks like the sidepod's top surface has leveled out at that height, its not a downward slope anymore, which is good, because it does not create as much lift.
Secondly, the Exhaust placement is very interesting, it is very far forward, and very low. This makes me speculate about the engine placement and the header design. I would love to take a peak under the cover!
Anyways, another thing worth mentioning... Shark gills right on top of the sidepod, also very far forward, leads me to believe that the radiators have a new extreme angle, thus needing a way of expelling the hot air ASAP, via the vast amount of shark gills. In general this reminds me of Mclaren's MP4-18 and MP4-19 and their struggle to get more heat out of the tiny cramped sidepods.
And the last and perhaps biggest change in the C24: TIRES! I hope this gives them the needed edge. I want to see that blue on the podium sometime soon.
