In addition to some other things, I was responsible for all vehicle simulation in Army of Two. This article is a good starting point. I was glad they mentioned implementing Pacejka’s tire model and the transmission differential in the article - those help a lot. Aside from that, I was surprised (not surprised) how important an anti-roll bar physics sim and suspension sim helped make driving feel “fun”.
That’s the most important follow up. Without it, you’ll notice that the driving feels icy - I see it in the demo video. Most folks who fail to do the anti-roll bar and suspension wind up with cars that easily flip on turns - so they make the tires slip or they play with the surface friction, which makes the driving experience worse.
