I would say it is a mixture of real world physics plus some anomolies.

Unfortunately the four stats can only ever be indications. Take acceleration, this in reality is a curve, the stat is just one single point on this curve, but the car‘s acceleration in real life will be determined by the curve and not the single point. Same applies for the braking stat. Not sure about grip, this stat is hard to get my head round what this really means in terms of physics.

Two cars can have identical stats, but different PR values, so this suggests either, that PR considers the curves behind the published stats (which I suspect) OR, that further factors are taken into account which we do not know about.
