What exactly determines a car's PP?

First of all, yes. I recognize that this might be pushing the limit in allowed discussion, but I'm still doing it for two reasons:
  1. I think it would be highly beneficial to all members, regardless of if they hybrid or not, to know what exactly goes into PP calculation. There have been many, many threads asking about how it is determined, or why one car has X PP and a similar car has Y PP, so I feel this thread is good as a whole regardless now that we are in a position to actually figure it out because it can be used to explain how it works when the question arises (or other questions where the information is applicable; ie. physics discussions).
  2. The existence of sorg's thread makes me believe that threads of this nature done for the purposes of research gathering are allowed so long as the specifics aren't delved into too much; plus some of this information is already being discussed in some of the other threads and it would be nice to have one place to see it.




Now, we already knew certain things that it took into account. Weight, area under the torque curve, downforce, aerodynamic efficiency (though it does a particularly poor job of it), weight distribution (though only in the extremely simple sense that it rewards you for piling weight onto the drive wheels and pretty much nothing else, and weight reduction doesn't seem to have any effect on it whatsoever) and (recently patched in, though also in a very poor way) drag.
As an example of what I'm alluding to, I've long suspected that there was a base tire grip statistic factored into the system (and, indeed, the game engine); based on how certain cars (usually, but not always, older ones) got the shaft on PP and how it correlated into how badly they slid around. And now we know that there was, in fact, a grip multiplier at play by the game engine that PP does take into account.



So what else can we add to that list of definite factors that affect the PP rating of any one car with the new knowledge that we have of GT5?

Very good OP.

I think we can take into account that the PP system is not totally flawed. Its true nature in GT5 has really shown how well it applies with the hybrids vs none hybrids (which truly i am amazed on that).

I am also amazed on how many things affect the PP.


I think the PP system was actually a great thing to brought into the game
 
Yes, I agree, I also have a sneaky suspicion that the amount of body roll affects the PP levels.

Also factor in Breaking in new engines and also excessive wear. (Exaggerated in case of RBX1's)
