Group C cars grip under acceleration

By redoing the tyres?

 

All we need is a nice confirmation like this for the complaints to stop

 

Performance calibration is kinda vague though, might as well be HP tweaks.

 

I agree with Frentzen the Sauber shouldn't have that much front grip...

It also should feel like it had tyres and a turbo of the era... Just like he states when someone asks about the turbo lag...

 

I continued my tests on this class yesterday. After exchanging opinions with others, just in case, I tried to re-tune the FFB, verified installation and reconfigured game by wiping out the Documents folder. The end result had very little differences with what I had before with a straight update to 1.5. So I don't think I have much left to do there. What IS interesting though, is having 180 degrees opposite views on each and every car, regarding which ones are more lively and difficult, and which ones are easier. Puzzling tbh.

After considering that my original test scenario could have lesser grip than normal due to the previous day being a rainy one, and probably the tarmac conserving still a little bit of moist, I swapped real weather for Sunny and track state as medium rubber, from Default Progressing that I had before.

Re-testing the C9 then and there, it clearly becomes easier, and yes, longitudinal grip under traction feels too high and could use some nerfing, as already announced. But it honestly did not feel bad on my end, just a tad too grippy, and still had to have some considerations with lines and throttle application out of the Bus Stop Chicane. La Source became easy with some heat on the tyres though!

Went back to my original test scenario for the other two cars of the class. First was the Nissan R89C. And it was...dissapointing. I found a car quite smoothed out and dulled down, and besides understeer at high speeds, I found it both easy (floor the throttle on exit, maybe a small correction on the wheel to keep the rear on check and that's it) and lifeless. As it comes out of the box, I find myself matching laptimes with the 962C, although with some setup work for high speed balance it should pull ahead. Power output seems to have been brought back to more realistic 1989 levels: at 85% boost it outputs max 792 HP, 40 down on the C9. Brakes are maybe a bit too powerful considering that they were the car's main weak point that season. I did not gather fuel consumption numbers, I frankly forgot to see that in the telemetry, and was not very interested on it given how much "fun" the car gave me. I did check tyre temps and saw that cambers would need reducing, specially at the front: the temps spread was at 12C there, and 6C at the rear.

As for the fantasy Corvette, I cannot call it any other way rather than "Group C EZ mode, rookie car". It's clearly the slowest of the bunch at the moment, its tyres nerfed down so the brutal mechanical grip advantage it had prior to 1.5 is finally lost, so now the rest of the car is laid bare to see. It's well balanced, nice to drive, pleasant, more interesting than the Nissan, but 2s per lap slower and with just decreased performance in all levels bar top end HP. Don't ask me about tyre temps, power figures or fuel consumption; I just did not bother to check its telemetry.

Considering the announcements made that these tyres will be adjusted, I will stop lapping with this class for the moment until the next update, and focus on other cars that I've been itching to try.

 

For me the 962 was about 2 seconds slower and had the grip like it was in a slot, slot car. I’m waiting eagerly for an update, until then the cover is on the group c cars

 

Just gonna put it out there...

We shouldn't be comparing the old R89C or GTP to the 1.5 versions...

There has been a tonne of work to correct the physics profiles of both cars... They wouldn't drive the same on their old respective tyres... Whilst the Sauber and Porsche don't have obvious differences on the set up screen that scream huge differences in physics profiles...

In the limited running I had with both the new R89C & GTP on release day I found them a vast improvement over their former selves... Just a little too tame out of the slow stuff... I do need to put more time into them... I have done some running in the GTP for an upcoming league race at Indy Speedway... That's on the easy side as well... Although I've got no idea how a car like that is supposed to perform on an oval, the downforce might just glue it to the road... The racing in that event will hopefully spice it up...

I think I missed the original announcement that this class was going to be updated... Since being able to drive AMS2 again I haven't been checking every post to see what people were saying...

There was a video someone made where they said it'd be nice if we could have a list of expectations with these tyres... As in the devs think they are this far along in the process with the soft tyre and this far along with the wet tyre...

That way leagues know which classes to avoid and which classes to avoid wet weather transitions in... And so do those setting up championships on the SP side...

 

Removed by poster for redundancy.
Sorry for taking up space.

 

they just released the patch. I’ll be trying after the Indy car race

 

The balance of the C9 is now quite more neutral at higher speeds. It is more tricky on the rear end at low speeds, but quite manageable IMO. Tyre wear is more rearwards, which means that car does not tend to get planted as the stint goes on. I guess many of the people who complained about this car on 1.5 would find the update a step forward, although it may not fully convince them.

Me? I'm undecided, because there are things of this car that I liked more on previous iterations. I liked the understeer at high speeds that required much more precision to get consistent laptimes and the higher power output, which has been neutered again on this update. I like more how the car now wears rears first than the fronts. I like the behaviour at low speeds more now too.

 

I posted my thoughts in the Release thread. It’s better then it was but 1.48 was more of the beast the c9 was

 

Wil be intresting to try this again. Before the hotfix this car had way too much grip in low speed corners. Shouldnt be able to have full lock and full throttle and still manage it easy into corners

 

Version 1.5.0.4 is more or less the same. Here's a video of me in the Porsche 962, absolutely flooring it in 2nd gear, on cold tyres, at the exit of Les Combes.

I actually have the throttle on a wheel button for demonstration purposes, and hit it slightly before the turn apex. All drivers aids are disabled. As you can see, the revs go up until they hit the limiter, and the car just goes slightly wide.
The rear doesn't step out at all, i just need to center the wheel on corner exit.

There's no challenge driving a car like this, it's impossible to make a mistake. I'm pretty sure this is not how the Group C car were supposed to feel like.

 

It also seems clutch overheat

 

I have auto clutch and drove out of the garage slowly. It's not clutch overheat, it's just the way the car drives.

 

Your video does show a weird behaviour. But top Group C cars were known for their understeer, not oversteer. Specially the 962C, which Tony Southgate estimated to have its downforce spread at roughly 25/75, compared to the 40/60 that his Jaguars had.

 

Again, these cars where not the undrivable,untamable beasts many people for one reason or another believe them to be. They were very close to F1 cars at the time, watch the video below of a real race onboard from the time, its a very controlled and balanced car.

AMS2 version of the C group cars might still need some further fine tuning, but I don't know why so many are looking for cars that you have to feather the throttle and counter steer on every corner, just because they are older cars and have a mythical reputation to be extremely difficult, when on real evidence they weren't.
