Since Scuderia Toro Rosso launched the STR10, much attention has been paid to the seemingly overly large airbox above the drivers head.
Curiously though, after comparing it to the STR9 from 2014, the airbox opening isn’t actually much bigger. Instead it’s simply a different design than last season, where the traditional airbox/rollhoop combination has evolved.
More teams than before seem to be including additional cooling options higher up the cars this season, with the airbox opening serving more than one purpose. In this case there is a clear divide, with the top section likely providing the traditional route of feeding air into the engine, with the lower section feeding air into the oil cooler, which has been placed higher up than usual and towards the back of the engine cover.
In addition, and new for 2015 on the Toro Rosso, there are two smaller openings further back in the engine cover; these will be used for feeding air to the turbo as well as possibly a bit of cooling for the gearbox and related ancillaries.
