The Ring: 4 hours on normal tires

Hello everybody,
I am new to this forum. I think this write-up section is great.
So I thought I'd share my endurance experience.

The mission
1st objective: 4hrs Nurburgring, and make it a bit challenging. There's nothing I hate more than starting an endurance only to find out I've lapped everybody a dozen times halfway through.
2nd objective: use normal tires (n1 or n2 or n3). Never used these before, thought this was a good opertunity.
3rd objective: Not buying anything new. Taking notes from the accounts of Mr. Scrooge. :)

Checking a typical line up. The fastest car wil usually be some NSX, at least it was with me.
From the cars I currently got I selected the Ford Escort Rally Car '98 with a stage3 turbo already installed. I thought this would be an effective combination, a race car with al little wing: downforce to cancel out some of the decrease in grip from the normal tires.
After a test run with N1 tires I found out that these take a staggering 2 laps (yes that's over 40km's :crazy: ) to warm up.
I bet they would have lasted for ages, but they weren't working out with the ford escort.

On to the race than. The field:

Honda NSX Type R '02
Chevy Camaro SS '00
Pontiac GTO '04
Evo VIII MR GSR '04
Honda NSX type S '01
And me of course. Ford Escort Rally Car '98

We're off. At about a quarter lap, I have overtaken the Type S, Evo and GTO. My tires are cold, which I forgot :ill: trying a bold overtaking move on the camaro. But it's only a matter of time. About halfway through the first lap I overtake the camaro.
Now I start paying attention to the track section times, and I notice something a little disturbing. I'm losing loads of time on the leading Type R NSX. Well, with my tires now warming up and a little extra effort, I try to minimise the time loss.
At this point I'm counting on the Type R, which I see as the main opposition to pit in lap 5, with me pitting in lap 6.

I carry on, with things looking bleeker every minute.
I manage a 7:59 lap, but other laps so far have been in the 8:05 to 8:10.
A few lawn mower moves in lap 4 led to me being overtaken by the other NSX, the Type S. With me now about 40 seconds behind the type R, I'm thinking of quitting.
So I give it another lap. I figure, I have about 30 minutes invested in this, and if I can't win it, I'll let Backwards B-Spec Bob finish it for some Cr.'s.

Well it's the end of lap 5, and Woohoo the Type S is pitting in ! 👍
But wait, there's another blue dot on that track map, that has passed the Start/finish without pitting. Nooooo, the type-R is gonna run another lap ! 👎
With my back tires going dark yellow and the front ones going light orangyish I need to get another good lap out of them. :scared:
Oh hell, I'll give it a go. I've come this far.
When I cross the finish line I'm 46 seconds behind the type R. So I try, and I try.
T1-45 seconds behind. Now that's some good driving.
T2 42 seconds behind. Hang on, I'm not that good. 💡
T3 40 seconds behind. There's something rotten in the state of denmark...erm I mean on the Ring.
T4 33 seconds behind. Could it be....no....YES, that stupid AI has sent the type-R for another lap on worn tires.
And sure enough there it is, "parked" in the grass. These are the moments you'd wish PD had put in a horn. :dopey:

Now another race starts, after the type-s has also overtaken the type-r.
The type s is about 30 seconds behind me with fresh, cold tires, with me going faster despite the now orange tires. I pit at the end of the lap, and come out with a 10 second lead.
On cold tires the Type-S is gaining, when the tires are warm, I win on good laps, and loose on bad ones.
Laps 5 - 30 show a reoccuring predictable pattern, of me loosing a little when on cold tires, but gaining more when Type S is on new ones.
I pit every 6 laps, the type S pits every 5 laps.

The Finish: I win (obviously) with a 2:01 lead on the Type S in lap 30.

Mission Success.

Let me know what you think,

Cheers,
DasBoot

Was it doing this?
 
That video is too funny, I almost bursted out in laughter (really weird to do at work..:-) )

Scrooge feels your pain.. currently doing the Tsukuba 9 hrs with the RUF and bspec driver managed to get himself practically lapped whithin 2 sets of tires... he wasn't doing as bad as Betty but was lapping .5 of a second slower than the Elise. Add the extra pitstops due to Scrooge not buying tyres and you have a recipe for disaster....

Glad everything worked out! 👍
 
The NSX in the 'Ring 4hrs isn't the only one to lose it on worn tires. The BMW M3 GTR Race Car in the 'Ring 24hrs does the same thing. Same with all the LMP/Group C cars at the Real Circuit Tours race at the 'Ring.

Goes to show you how dumb the AI can be sometimes.
 
This brings in my mind if AI drivers are programmed to go pit only every 4-6 lap, even the ring is more longer than any other track, even though it's doesn't work in Tokyo Enduro, they go over 16 laps and still goin'.

I haven't figured what is the max laps driver can go through Ring without losing tyres in the race.

I liked this post, too, great story and hopefully I could drive it too soon
I have too much interest to tune all my cars by now :dopey:
Let us hear more of your races, so interesting they are :)
 
I think the AI uses a simple formula to determine if it can continue racing. My best guess is that it calculates current tire life and if it is over a certain percentage it will go out again. unfortunately the longer courses like the Ring will punish you severely for doing this.

It is unfortunate that the AI are a little stupid when it comes to pit stops. You would think that it would be easy for a computer to calculate. For instance:

Lap 1 - 15% tire wear 85% remaining
Lap 2 - 20% tire wear 65% remaining
Lap 3 - 20% tire wear 45% remaining
Lap 4 - 25% tire wear 25% remaining (Probably should pit here but could push it)
Lap 5 - 25% tire wear 0% remaining
 
I did the race for 2 hours and handed over to the B-Spec, when I got back I was a lap down! He managed to "miss" the pitstop! A few times!I saw it with my own eyes, the pit icon was on but he just drove past it. :ouch: I drove my butt of to win by only 10 seconds!
The car that was second pitted for the first time on LAP 25!! :nervous:
 
This was probably my most nailbiting endurance when i did it on my old saved game (im yet to do it on my no money game).

I personally chose the NSX Concept car without a single change to it.

My problem was i over estimated my tires and did an extra lap, luckily so did 1st place.

I wrote it up somewhere on here if people wanna look for it again
