What's the most realistic car in Assetto Corsa?

[Sassanid]

As far as handling and physics go, which one is it?

[ling.speed]

GT86

Can you elaborate? What is this "most realistic" title based on?

I read somewhere it was the 458 GT2

IER P13c. Ok it’s not a Kunos car but it is in Assetto Corsa…if you install it.

The team that made it work with real world LMP teams. They rewrote physics files for tyre heat and aero model and so on and so on. Yes it’s a paid mod but treat yourself.

It's a half joke. We could discuss good and bad things about every car but devil is in the details...

The issue is that the faster/more fancy car you pick, the more things can go wrong, and fast = very stiff = high frequency = requires higher rate of physics to produce good results.
So in ac the faster the car the more stuff gets skewed and adjusted for fixed rate of physics. Which makes numbers look not much relaistic. Thou the good thing about AC is that it does not try to follow realistic numbers but to make handling have sense.

Personally i think kunos have made great job with ferrari F1 cars considering limitations of the game they drive in a realistic manner.

Kind of similar issues, but with lack of data and problems in suspension modeling happens in some older cars. (many solid rear axle cars behave not great tbh).

So the best car is really the one with modern suspension (well aligned with stiff chassis) and not much else stiff or downforce where stuff can go wrong. Thats GT86. It has no electric/electronic stuff either. Which while pretty great in AC, still require data thats properitary and it cant be expected to be "realistically" simulated. Your IRL street car has probably more lines of code in it than whole AC.

Also tyre load sensitivity as is in AC seem to be slightly better on front engined cars than mid/rear, again GT86 is good here :).


Modders pushed far beyond limitations of AC physics, fixing, going around stuff, or even adding new physics through CSP so some mods are definitely "best"... as for GT3 458 ... Kunos likely had more data on it than other GT3s but there is nothing special about it beyond it being a popular car people want to prise. Within GT3 i feel huracan is better... it was the car that got ported to ACC near 1:1 ... or maybe they did it in higher fidelity for ACC prototype and then moved to AC (before ACC was even a thing).

Can't tell cos I haven't driven them irl, but cars like Audi Sport Quattro, Alfa 155 Ti V6, BMW E30, Ferrari F-40, Porsche "Moby ♥♥♥♥" and several others feel really convincing.

Interesting post Ling, but doesn't the real life GT86 use brakes to simulate a LSD? If that is the case (pretty sure it is) and with what you said perhaps the ND Miata would be the most realistic car?

Thanks, I remember you recommending this particular car before. In my experience, paid mods are usually the best ones out there, so that's a good sign

Interesting stuff! Believe it or not after all these months, I actually drove the GT86 tonight after reading this thread and the car is a lot of fun to drive and doing power slides with TC off is a lot of fun. I can see why it's such a popular car online

I remember reading somewhere that the 458 gt2 has the most realistic handling car physics in AC, which in turn made me happy because it just so happens to be my favorite GT car in the game. There's just something about the way it handles that sets it apart from any other GT2/3 car in AC and I always find myself saving a spin and correcting the car with far more confidence and reassurance in the 458 than any other car, but I'm just not sure what people base these theories on. I wonder if Kunos have said themselves which car is the most true to life in term of physics and feel. I'm guessing no since as devs they want us to drive them all.

Yeah didnt want the post to go too big, ofc IRL you have those things, but in game all cars run in sport ot track mode, which in case of GT86 would turn all that off i think. I was comparing it to cars like GTR, hypercars or stuff like SUVs where electronics are always on.

And then there is a case of MP4 12C (v1) ... car that drives like ♥♥♥♥ without electronics IRL and in game haha. So we can say it's "realistic" but nobody is going to celebrate that realism haha.

I've driven both the GT86 and a Ferrari F430 at the limit on a real life circuit. The GT86 was doing the same speed in the corners to the exact kph in game vs. real life. The 430 isn't in Assetto Corsa, but the handling characteristics were really quite similar to the 458 Italia

You have to be careful comparing times and corner speeds like that. The same car can have different speeds over the course of a day just due to temp, let alone heat cycles of the tires, setup, maintenance, etc
