Aerodynamically the Scuderia have struggled with several key areas for some time now, with the team hurrying through upgrades too quickly, often resulting in components that didn't resolve the problems at hand. Since his arrival James Allison has installed a different structure, with a more pragmatic approach, addressing the core issues.
An area where Ferrari are leading the way this season is their sidepod cooling package, which has allowed the team to close down the cooling outlets at the rear of the car, which in turn will reduce their aerodynamic inefficiencies.
Before we have a look at their solution lets just examine how the radiators in an F1 car differ to those we see on our road cars too.
Giorgio Piola shows the orientation of the radiator within the SF15-T's sidepod.
From this image you'll note that Ferrari's radiator is much flatter than we'd normally see, making it more difficult to keep flow through the radiator efficient. They've not only banked their radiator for this layout but also staggered it (twisted) allowing for more surface area, maximising the exterior aerodynamic bodywork shape.
Having already visited the hot climes of Malaysia without having to open up the rear bodywork, it's clear that the team have an efficient solution, allowing for a more adventurous rear end aerodynamic package.
