The Pagani Huayra BC Up Close

The front splitter has a raised center section to help reduce pitch sensitivity.  The splitter’s side winglets reduce spillover on the splitter and probably act like vortex generators that help manage flow around the front wheelwells and the sides of the car as do the front canards. The canards are not a particularly efficient downforce creating device but maybe they’re vortex generators and a styling element?  The heat exchanger venting above the splitter reduces its effectiveness by reducing stagnation pressure.  At least the heat exchangers have beautiful properly shaped carbon ductwork that exit on top of the hood that probably contributes to downforce as well.

This is the upper fender vent.  It strips high-pressure air off the top of the tire to help activate the front diffuser and to kill the lift that the tire can create.

The top of the beautiful carbon fiber fender with the flawlessly molded vents. Drool.

You can see the exit of the rear fender vents here.
