This picture via Nico / Slideways @ Autosport.com shows the unique double stacked radiator arrangement with the mercedes sidepods. This explains the splitter seen inside the sidepod inlet, which I queried in my earlier analysis (http://scarbsf1.wordpress.com/2011/03/18/mercedes-w02-preseason-side-pod-exhaust-update/).

More analysis and properly hosted image to follow.
