Physics discussion thread

Out of curiosity, are you a big fan of AC and ACC? Because both those games, I determined recently are heavily understeer-oriented, which I believe is because people are accustomed to driving FWD cars IRL and because road cars are tuned more for understeer for "safety" reasons. In my opinion, this is the wrong approach.

Are you comparing the front grip in AMS2 in your open wheelers to real world experience, or to other sims?

If you're comparing to real life, exactly what are you comparing? I look at the video of Max you posted and I compare to your lap and I see something almost identical - except that Max is right on the very limit (as you would expect) and he and the car are both reacting to being at that very limit of grip. To me, every single F1 video looks like they're absolutely on rails. With all due respect - I see nothing "wrong" in your video except that you don't look like you're right on the limit. To be fair, finding the limit in the fastest of open wheelers is extremely difficult and I'm nowhere near it myself - hence why I'm racing things like the McLaren MP4/6 and MP4/12C

If you're comparing to your own personal real life experience, are you comparing RWD cars? FWD? How about the quality of your tyres? An old, or cheap tyre will just slide straight ahead, but a high-quality tyre continually tries to "grab" the road as you slide. And I know this, because every single new tyre model I've bought I've pushed hard to find their limits so that I know just how safe I am in my cars. I imagine slick tyres are even better at doing this.

 

Like i said, i’m not an expert.

My real life racing/track days are limited to karts in dry/rain, rallying in gravel and snow and fast road cars with UHP tyres.

I’m very well aware by merits i’m not qualified to say anything about the Pirelli slicks of a F1 car.

AC and ACC - i like them like all sims, but both have their own issues.
The OG AC is complete opposite what AMS2 is.
Way too rigid front tyres because of 1 point tyre contact patch.
And don’t even let me start about the kerbs in that sim.

Best sims to simulate the front tyre grip are IMO iRacing and ACC. In both sims you can really have the front tyres in slip angle, but generally it doesn’t reward you as massively, it’s not as gradual and there is element of danger present.

In ACC, if you overshoot the corner, but manage hit the corner entry and decelerate too fast the front gives up a bit and you lose grip. In that sim the car balance is very important.

In AMS2 in the same situation the front just finds grip magically and starts rotating.
