From what I can tell, the dirt on the modeled car does not match 1:1 to the real car, in fact it differs substantially in all areas. So the idea that they used the dirt from the real car (i.e. from photographs directly) isn't strictly true - although they obviously have reference material of the real thing (race grime in general at the very least) going by the overall effect.
The artists either made some dirty texture overlays by hand that come close (ish), or it's a "snapshot" (e.g. baked to texture) of a procedural method, or intended to be a "target" for the final build to whet our appetite based on a mixture of prototype output and hand-authored work. The number decals (and anything else that is treated as a decal in their livery system) in particular look separate in some way, but the streaks, smudges and blobs could easily be generated by the looks of them (using a combination of morphed primitives, small textures - like the carbon effect - and shaders), both on the decals and on the paintwork.
There appears to be a severe mapping error of the dirty texture on at least two locations on the car. That is not at all typical of PD's handiwork, which might suggest it was cobbled together.
Hopefully we'll find out for sure, soon.
Probably the Hokusai/Shogun/Ronin? car model artist being whimsical. Kaz saw it, looked up, out to the middle distance and remembered why he loves his kooky band.
