Ferrari copy Red Bull exhaust system
Just as rumours suggested in recent days and weeks, Ferrari's aerodynamic update at Valencia includes a revised exhaust system that mimicks the Red Bull's design. Rather than exiting the exhaust gases through the upper side of the sidepods, the pipes are now relocated to push gases out just above the car's flow, ahead of the rear diffuser.
At the same time, Ferrari also shielded its lower wishbones to protect them from the heat while strips are added to measure the exact temperature of the suspension arms. The team also revised the rear brake ducts to make sure they don't fetch too much of the hot exhaust gases.
The change marks the departure of the high exhausts, introduced by Ferrari and quickly followed by its competitors. The last time a low exhaust was tried was on the McLaren MP4-18, again a Newey designed car. That one however had its exhausts exit into the diffuser, causing troubled pressure differences. The MP4-18 eventually got revised with high exhausts before it was first raced.
