I'm basically asking, "is it normal for the BROBOT track times to be faster than the Automation times by a second or more?" Because my first car has an automation time of 2:24.35, and in BROBOT it's 2:23.04

Sometimes. I think during practice for 1955, they were slower for some and faster for others. Or was that 1966? *shrugs*

Re: BRC QuER - Hockenheim 1000 km 1976 [OPEN]

In earlier versions the cars had less power, suffering a lot more under the fuel load. It is normal that the times are faster because of not having to do a standing start each lap ;)

Just a suggestion or question to overpowered cars.
My car pretty much has wheelspin up to 180kph. So at 80kph it drives around in 2nd gear and the driver applies 30% throttle.
I think in real life a driver would choose a higher gear and apply 80-100% throttle, since that it way easier to control - and it also saves some fuel (i think?).
Same thing for racing in the rain.

Don't know what Brobot does there ....

Re: BRC QuER - Hockenheim 1000 km 1976 [OPEN]

In Brobot throttle losses are not modelled. So it depends on your torque/BSFC curve if you would be better off in a lower gear or not. I could see a way of calculating this, but it makes the whole driver model a good bit more complicated. At some point I would like to introduce a more intelligent driver model anyway, for example backing down when having a huge lead, being less aggressive in the final laps if no opponents are around, saving fuel to make the last laps without another pit stop, ... There are many possibilites and each of these strategies could be controlled by the player for example by setting some threshold values. But it turns out pretty complex very fast. So maybe in a major update which only focusses on driver intelligence :)

yeah, I had a brain fart. Forgot about the flying lap times

Re: BRC QuER - Hockenheim 1000 km 1976 [OPEN]

Slow, not significantly better fuel consumption, AND horrendous tyre wear. That's clearly not how it's done.

I think I've lost my Automation mojo these past few months. As I'm unable to spend much more time tweaking the car, I'm withdrawing from this event. I'd be happy to contribute something "different", but something crap isn't going to be helpful!

Re: BRC QuER - Hockenheim 1000 km 1976 [OPEN]

I believe something happened with pyrlixs polonez body soon before i submitted my car which messed something up so that my game didnt recognize the body for some reason which ruined all my stats for the practice session. Ive now recreated the car and its now slightly cheaper and has wider tires but my drivability went down at least 5 points somehow. It is slighly faster i just need to do more stuff to optimize it with the things that changed.

With this im wondering if not having a body lowered my fuel consumption for my car and was the reason i had lowest fuel consumption.

I did learn i have a lot of tire wear though so i will probably make changes for that. Will the wider tires change that as well?

Just a quikc one for someone new to the brobot system. I did a search but couldnt find anything.... Could someone explain what it all means when it comes to the r/dmg/f column? I assume from what ive seen on here that F is driver fatigue? Dmg is car damage? So i can only assume R is tyre wear (rundenturnenwearenouten in german perhaps?? :D )

Front Tire Wear, Damage, Rear Tire Wear.

Driver fatigue is the little blue bar by the car's number.

Speaking of which. Can my numbers be made white on the blue background? Black on blue is almost impossible to see.

Very interesting practice. The speed of the cars is amazing.

For my own cars, I am confused why my second car is shown as only doing 13 laps when it actually ran out of fuel on lap 17.

Did it start later? It could be that the leaders of the practice had been doing 4 laps when you started. My cars started 12 minutes after the start, which is about 6 laps, for example.

I actually have underestimated my fuel consumption. Did the whole 20 laps with 0.2 liters to spare. Also the ehm... let's call them "joker cars" (as in ones that were entered without much consideration that an endurance race might be longer than 1 lap), have mixed the field up quite a bit, so retrieving data that I could use is now also more complicated.

Re: BRC QuER - Hockenheim 1000 km 1976 [OPEN]

I was really happy with the tire wear on my N/A car. It's lap times only fell off ~1 sec. by the end of the 20 lap run which was almost a full fuel run. I only had a few Kg left and I was burning 3.75 Kg/Lap.

My turbo car was really thirsty, and not much quicker, although I was no where near the weight limit. I could lose another 300 Lbs. and still be within the rules, so it may be something to tinker with in a new model. Using the same car body definitely didn't work out well.

Do we know how long a full pit cycle will take? Like entry, plus pit stop standard pit stop (we can come up with a range here for a better estimate), plus pit exit? I really want to know how much time a car will lose in the simulation from stops alone. I can't keep up and be economical, so we need to know where the line exists. If I was 8.5s/lap slower I need my fastest competitors to lose at least 170s/20 lap cycle in a worst case scenario (likely less since my car holds up well on tires).

If the pit stop cycle is fast enough, there is no hope in beating faster cars by staying out.
