In January, Aristotelis started to publish a series of “Real X vs. Assetto Corsa representation” videos in cooperation with his friend and automotive journalist Maurizio Spinali. Today we received the lastest combo with a little surprise: The showcased Audi S1 isn’t even available to Assetto Corsa yet.
The highlight is that Aris starts to unleash the “rally soul” and does a few successful Scandinavian Flicks. As usual, the AC video almost perfectly matches the real footage – even on far-away physics corner cases.
Simulators usually (need to) focus on a range that they want to simulate, which doesn’t magically include corner cases. Assetto Corsa for example is damn good at racing pace, but doesn’t shine in slow driving handling. Cars can’t even stop inside the physics – with extremely low speed the car would suddenly stand nailed to the track and you need some serious and unrealistic effort to get it moving again. A different example is the Aero simulation; it’s quite sophisticated and realistic while you use a high downforce car “normally”. But as soon as your car jumps, it basically leaves the simulated area and stays airborne in a stable way. Real race cars will lose their ground effect and flip due to the downforce bias in the rear, some needed only a tiny bump and some slipstream.
I don’t want to say this is bad, as we are talking about corner cases that usually do not apply to driving in AC and it would have been a bad choice to invest effort here – my point is there are acceptable corner cases which aren’t well simulated without hurting the simulation aspect. Coming back to the video I’m asking myself if this also applies to the Scandinavian Flick and what it means that Aris could actually recreate it in AC.
I’m not convinced that the Scandinavian Flick is not just a really usual application of already well simulated physics, in fact it’s “just” some tyre load and weight shift physics. But this either means Assetto Corsa does simulate whatever is required very good and reacts realistically just by applying the correct numbers, or that the Audi was more or less modeled and forced to behave like this.
Of course I don’t have a clue what the answer is, but both cases would be fascinating. Somehow it seems unbelievable that you can have a sim that recreates such a behavior just by putting in the manufacturers data.
Very important note:
Remember to subscribe guys! The more subscribers we have, the better cars we can ask from manufacturers and boy do we have some… surprises for the next videos!
