saloon car aerodynamics

Recently the touring cars have a lot smaller frontal area with the front wheels exposed. Is this so they can extend the splitter back and get more downforce or is there another benefit

[greenamex2]

I know the British touring cars have regulation width box arches but can't widen the front to match. The result would be a narrower looking front.

Given that touring cars are supposed to use production shells and other bodywork is it also the result of the manufacturers having smaller frontal areas?

I thought Sergi whatshisface introduced it to help cooling the front tyres which often over heat on FWDs

exposing the top of the splitter to airflow was first seen on the BTCC Nissans .
If I remember correctly ,this design helps to keep the downforce level at the front of the car constant even when the front goes down under braking,wich would normally cause huge variations in downforcelevel.
