Sauber Sidepods are found in these pictures. Its only a mock up chasis but its exactly the same as the real thing so I assume this is how the sidepods really will look like.

Also, Ive noticed that in the Renault driver seat fitting pictures, the Renault has a very narrow Airbox (or whatever its called). See for your selves.

and finally, more news on the R31, this is from F1 Technicals forums.
“Firstly it appears to be a clean sheet on the chassis side, the nose is distinctly more “V” shaped, I’m told the shape resembles the B192 with a rounded underside and flatter top.
As mentioned earlier (and in my autosport.com post) the KERS batteries are in the sidepods and this lifts the radiator inlets upwards into a McLaren like shape.
No word on the Gearboxsuspension layout, although Lotus heading for Red Bull may suggest Pullrod is not on the cards. Renaults 2010 car shifted the rockers & dampers towards the front of the case, this makes them sit neatly in the shadow behind the engineairbox. So they might not need the access issues of pullrod.”
thats all from me!
