Automobilista 2 V1.4.5.2 & New DLC Packs RELEASED!

I had a question about the new DLC Supercars Pack - Part 1 as it’s on sale at Steam for $4.99. It adds only 3 cars correct? The Mclaren Senna, Brabham BT62 and the Corvette C8 Z06. Should we expect any more cars to be added to this Part 1 DLC or will the next cars coming be in Part 2? I apologize if this has already been asked and answered. Thanks.

 

It's 3 cars you mentioned. More street cars are announced but for part 2

 

Thanks so much for your reply. I appreciate it. I think the 3 cars, especially the Brabham are worth it for the sale price.

 

BT62 is absolutely worth it. It's perfect for a single manufacturer race/league like the PCup except the performance is far higher.

 

I recently discovered speedtrap values for the GT1 race at Hockenheim 1998 in the official Porsche yearbook of 1998, the cars were all in their low-downforce configuration as well and the values were all taken in the race and the cars in AMS2 seem to be lacking a bit of top-end:

Porsche GT1 #8: 307 km/h
Porsche GT1 #7: 309 km/h
McLaren F1 GTR: 316 km/h
CLK LM #1: 320 km/h
CLK LM#2: 319 km/h

And these topspeed values for Le Mans 1998 from the official Le Mans yearbook, Qualifying and Race taken before the right hand before Indianapolis:

Porsche GT1 n25: 310 303
Porsche GT1 n26: 310 298
Nissan R390 n30: 324 312
Nissan R390 n31: 326 312
Nissan R390 n32: 317 311
Nissan R390 n33: 321 307
Mercedes CLK-LM n35:325 308
Mercedes CLK-LM n36:322 307
Mclaren GTR n40:315 306
Mclaren GTR n41:313 308

Seems to make sense due to slightly different engine configurations for Le Mans by ruleset and by being configured to run 24 hours ideally. And as you mentioned and I tested a bit myself, the values in AMS2 seem to be considerably lower with basic setups (lowest radiators and wing settings, max boost), not sure one can gain about 20 km/h with a good setup alone for the McLaren on Hockenheim for example (whose 316 km/h even was in race trim).

 

Porsche experimented with a lower downforce aero setting in the practice days before quali which brought it much closer to Nissan/Merc/Toyota but later decided not to go with one as far as I could read.
You can test on Monza 1970 with the high speed ring in AMS2 and zero wing. Last time I tried measuring top speed in the Porsche I got 316 kph there. But then power was reduced and I never tested again.

 

That's interesting, where did you get that info from?

There were no real practice days for Le Mans though, just 1 day of Pre-Qualifying and 2 days of Qualifying, so they must have tested it at the Pre-Qualifying then I'd assume.

I was not trying to fully test top speed though, just compare the top speeds the real cars achieved at the same track of Hockenheim which seem to be quite a bit higher than what you can get in AMS2.

 

What were you wind and temperature settings? That would make a huge difference...
What about engine and brakes "%" openings...?

 

And I set the date to the 28th of June 1998 and the time to 2pm, most races that season started between 12pm and 1pm local time though I don't know the starting time for Hockenheim specifically

 

Just made another test at Monza 70. It's physically impossible to go beyond 308 kph even with extreme settings. The parameter that seems to affect a lot top speed is tires pressure. The car is either too draggy or having too much rolling resistance or a combination of both.



The low downforce config is mentioned even on Wikipedia as yielding 330 kph. Even though that value could be exaggerated it is not unheard of gaining or losing at least 10 kph through different aero packages especially on very slick cars like GT1s were

 

Well idk, a Wikipedia entry without a source claiming every official source is wrong, I doubt it. Especially as they were on a low-downforce package already, I can't see them just dropping 20 kmh topspeed on a track like Le Mans.

Interesting bit on the topspeed testing though, hopefully it get's reviewed by the devs.

 

I did comparison between 1st January (1C air - 1C track) 1st April (1C -1C, something isn't right with the values) and 1st July (24C - 32C) and the difference in top speed at Hockenheim 2001 (bypassing the 1st chicane) is 307-308 kph in January, 305 kph in April (again something isn't right with April as the track seems suddenly very slippery and temps are the same as January) and 305 kph in July. Considering how extreme is the setup I am using I think we are missing at least a good 10 kph somewhere if not more.
My money is on excessive rolling resistance but who knows.

20 kph is too much I agree but maybe 10 isn't out of the cards. It doesn't take a lot to have a slightly less downforce and less draggy package: a diffuser and/or a different wing make a lot of difference on an otherwise very slick car.

 

@CrimsonEminence Just tagging you here so it doesn't go under the radar as it is in an older thread, hopefully something worth checking for the devs.

 

Another thing that just came to my mind, maybe the LDF package is just not reducing drag as much as it should? You could do another test with your settings on a track like Spa where you have a very long straight but in the normal downforce variant if you have the time?

@CrimsonEminence Is this something you guys are taking a look at or have noted?

 

Rolling resistance is indeed an issue that needs to be addressed...

It's also why the defaults have such over inflated tyres for a good tyre patch... As the AI on tyre pressures that the player would get a good tyre patch with are just plain slow in a straight line... There's like a 20psi difference between the 2 that I've noticed in my testing...

The few cars I've looked at with LD version just have their wing setting lowered... The actual drag figures are the same...

This is one of the things that will be changing for my Group C mod...
