Mercedes runs new exhaust system

After having tested the new exhausts at first free practice in Valencia, both MGP cars were fitted with outer blown diffusers on Friday, set to race the new system. Even with the FIA changing the regulations to reduce off-throttle exhaust blowing, exhaust system like Red Bull are still putting the exhaust gases where they are most efficient.

With the new layout, Mercedes hope to make best use of the little exhaust blowing that is left in the system, and at the same time try to resolve their cooling issues by opening up a hole in the rear end of the sidepod, replacing most of the gills that previously tried to provide some cooling for the internals.
