Looking at the R18, i take it they scrapped the rear wing width thing where the teams would claim that the outer parts of the wing was actually not a wing but a rear fender exstension.
Edit: rather interesting bit on the front aero, from Audi press release,
With respect to designing the front end, the engineers enjoy new freedoms. Instead of
a diffusor, a genuine front wing with a flap may be used for the first time. This
promises aerodynamic advantages and lower costs, as this part of the bodywork will
lend itself to easier modification to suit the various race tracks. In the past, it was
necessary to produce different bodywork assemblies.
