Now remove the wings, and you will find that a high percentage of the "added" downforce has all but disappeared. The reason is that the device does not produce downforce, ie: negative lift- but simply helps remove the lift causing high pressure areas that develope undercar and grant the wings more downforce.

However, the new rules has opened a new door for further research in aerodynamics. The following image is an analysis on the actual car with the diffuser producing the up-wash which is causing a lot of problem nowadays. I did that to study the performance of newly designed rear wing with close proximity to the car.
