Automobilista 2 V1.2.3.0 Update Released on Steam

Reiza Studios has updated Automoblista 2 to version 1.2.3.0, and added two new cars, improved Real Weather features and another round of fixes and improvements.

Automobilista 2’s August 2021 update is now live on Steam. In typical fashion, developer Reiza Studios has offered new, free content plus several other improvements and fixes to the racing sim.

The new content this month is a classic American muscle car in two flavours. The Chevrolet Corvette C3 has been added to both the Vintage Touring Car class as well as to the GT Classics Class in the "R" Spec to compete with the recently added Porsche RSR. The Corvette C3 was teased last month but was offered only to AMS2 beta users before this build.

Another significant improvement that has been added in this build is the addition of accurate environment temperatures in the Real Weather system. The Real Weather system in AMS2 allows users to select accurate current weather for track locations, and even historically accurate weather when past dates are chosen.

On the physics front, many of the cars have been given a tire tread adjustment to go with the potentially significant changes to the clutch inertia and tire tread fixes.

Well, right after curing the former patient, the Porsche RSR 74, they made themself a new patient to cure, the Corvette C3 R.
I'm not even convinced they "cured" the RSR yet. Still isn't fun without drastically changing the setup.
And I love AMS2 by the way.
 
RIP that class's hotlap records! I'm a very average racer, and in 30min, look at what I did to that class's record. And still, I think I could've kept at it and gotten in the 56's.

Nice to see more updates!
I tried out the C3 touring version and honestly wasn't too impressed with its handling.
It brakes as good as an ocean liner and has zero braking bite or sense of forwarding weight shift while braking. It just goes light and slides than you feel the tire scrub effect kick in as you turn the wheel to try and correct the slide.

Welcome to reality, LOL! An unmodified C3 is a boat by modern standards. It is softly sprung and has mushy power steering & brakes.

Tires from the 70's are bad, who would have guessed. AMS2 probably also has too much longitudinal load curve slope, that's what it looks like at least.

Either way I wouldn't expect much from roadcars before 2000. They only really started putting crazy tires on them in the turn of the century. Although even my NSX with the crazy tires Honda put on it in the 90's is "on ice" to most users, even if it pulls north of 0.95g.

We used to have a BMW Z1 in 1989 that was able to surpass 1G lateral on series Pirelly Tyres. quality tyres were quality tyres, even in 1989. In fact it, seems to me that modenr tyres are not as good in regard of grip as they used to be in the 90's. I have that feeling about Winter tyres in particular. Low drag and eco frienly, but not as grippy as before. I guess without electronics, todays cars would not be that safe.

I'm talking about sustained, mind you. I don't know what you mean by "series tire", but I'm not aware of any OEM tires which could pull 1G in the 80's.

Either way, no in general. Tire grip has gone up on average in sport and all-weather tires. Especially on the very low treadwear stuff that gets mounted on supercars. There are compounds like RE010, A-022 that were grippy in the early 90's, but they've been surpassed some ten years ago by tires that wear better. Now some lower end cheap sports tires are meeting that performance. You get 1.4 - 1.5g sustained out of road tires if you disregard tire wear.

Winter tires are a bit of a special case with how easily the compound gets destroyed due to the heating performance and softness. I'm not surprised if they're harder on average with a wider heating range and lower peak mu now.
 
I have worked some on physics of C2 from 1967 Lemans. The car is very heavy, rather tall CG, super powerful. Brakes are rather modest. I just can speculate why, I guess perhaps car this big was given a priority to brakes durability over brakes performance, I have no exact knowledge of that, but such guess makes sense. I can't recall exactly but during the research I read that some Vette, I guess C3 from 69-71 some of those years, or all of those years, had to start braking extremely early. I think if this heavy car lacked braking it was not because tires would have lacked grip, but because brakes would have lacked power.


Thats some nice onboard, with rather good second lap. Pretty awesome on the limit braking into T1:

And thats probably with better tires and better brakes than it was in its youth time.

Braking issues are generally caused by bias imbalances or if cooling is insufficient (I doubt it is but it might be) rather than the brakes just being weak. It's pretty tough to find a brakepad material that won't allow locking the tires even if you input 100bar into the system.

Was watching the vid, thinking; 'Man, has AMS2 come a long way...

Aaanyhow, on the subject of brakes. Donohue says on 'The unfair advantage', driving a Ford GT for the first time:
When I started going faster, though, I rapidly realized what the car's main weakness was. No one knew how to make brakes last on a 3000-pound race car. After the brakes warmed up - in two or three laps - I had to push so hard on the pedal that I couldn't concentrate on driving the car. I really began using the gearbox then, downshifting as early as I could without over-revving. Walter even showed me how to go around the banks low, then climb up them during braking to help cut the speed. Anything we could do to help the brakes. The engineers were trying everything: finned disks, cast-iron disks, copper-coated disks, meehanite disks. Nothing worked. No matter what, in a few laps they would all go to hell. Much later they found that part of the solution was to go to bigger disks. We were running 7/8-inch-wide discs at the time, and 1-1/8 inches turned out much better, even in good old cast-iron.

Modern tyres not as grippy as in the 90s? 1 g lateral? I have done over 1.5g lateral with my I30N on standard tyres, on the country road mind you. And that car has a higher weight center then the Z1

Yeah, so it is a temperature issue then. Usually braketemps aren't really a problem in racecars, but this is in racecars with large disks and decent venting, so from the mid-70's onward. It's possible it was a real common issue in the 60's and earlier. They'll definitely lock up for a lap or two though.

Don't mix up peak G with sustained G.
