The first part with the donut definitely is not ingame. The reason why it looks weird is because it clearly is just animation / render, where they have put the car 3d model to make that movement and then just added spinning tires etc. to make it look better, clearly there is no physics calculation or anything going on.
Probably if you go and do donut in the actual game it's not going to be realistic / natural looking then either, but well you maybe got my point.
