@TonyJZX that is one solution for sure.
Another week is here, another Race C is here, and guess what, it is Gr.1 race. And new problems arise. VGT cars are not competitive here, since it is a R18 event as everyone can see... and do you guys know why is it like that? Because someone over there in PD said, let's make all cars have same fuel amount. 919 should have around 63l, and R18 should have around 54l, that would made change and rivalry between those too. But no, it is what it is.
But problem that I wanna discuss today is why LMP1 and odler LMP1 cars cannot be in same group. So it is fight between R18 16' and 908 10'. Both are diesel cars, so they are economical right. But there are differences, R18 is made by newest rules, while 908 is old school with proper V12.
And here is data from my MPG testing: R18 16' ~285km; 908 10' ~270km. By this data it seems that R18 has better chance in this race.
Let's take BoP in calculation: R18 16' 100% Power, 100% Weight, so no changes, still ~285km; 908 10' 90% Power, 100% Weight, so this changes a bit consumption to ~282km, so now they are almost even, or are they?
R18 gives constant 527hp and has 1929lbs, 908 has 630hp (BoP) and 2050lbs, so it is heavier but has more constant power, but peak power goes to R18, since it's hidden eV part that should have around 300kW additionally.
So all in all, R18 seems as better solution right? Well, I am not best driver in the world, but with both cars I can achieve approximately same lap times around LeMans, so you ask what is the problem?!?!
Look at those two pictures now:
First one is R18s, second one is 908s. Problem that R18 has it needs to rev all the way up to limiter in order to get that max power output, while 908 doesn't need (shifts at around 5500-6000), but can. This means that 908 can fuel save a lot and not loosing lap times at all. And all this is because PD chooses to make MPG calculations on AT transmission with BoP included, so everyone is happy and can play the game.
And in this weeks Race C, you need when in good group to drive R18 hard, and use up apporx 165-170l of fuel, while you can do same thing in 908 with 110-115l. Now if both cars can do same lap times (at least I can do approx same times with custom setups, around 3:22s) this means that R18 will lose a lot of time refueling. So, why would I choose R18 over 908, to get that boost at start and constantly hope for more boost after every corner, yet track is power oriented with long straights?!
There are more of these examples, but 908 is in it's own class with this. Simple older LMP1 cars cannot be in same group as newer ones. Same goes for VGTs and Gr.C.
What's even worse, all Gr.C cars must be revved in order to get at least some good times, and by revving you lose a lot in pits. Higher revs, more fuel is needed.
This needs to be addressed ASAP.
