Here is a video from Force Motorsport, the team that has build the Hyundai, this from a build up of a Mazda 2 under the same concept:

What is especially cool about this AP4 concept is that it allows for nationally homologated cars of R5 performance, which means that manufacturers/importers/dealers that want to do a national rally effort, and dont have a homologated car (like Volkswagen), can do it on their own with a ready developed package.
For New Zealand and Hyundai, this opens up for them being able to use the popularity of Paddon to attract fans in a more optimum way than him driving an old Ford (even tough he won Rally Otago in one last year.)
The factory rally drivers are in effect car salesmen, if they like it or not, so to be able to be a part of the marketing is of course very important.
