At the same time the flow at the under-body will be reduced and the wake flow is directed into the ground. An automobile diffuser is traditionally used as a downforce generator, but it can also be effective for drag reduction for some type of bodies.

The diffuser generates a pressure recovery for both sedan and wagon, but for the sedan it also made the wake more symmetric. This combined effect is why the diffuser generates better drag reduction for the sedan.

MapTun Rear diffuser is great, looks great and has the effect, but it is quite expensive – € 394,88 excluding vat.
