I just did a 30 lap race in the Aerial Atom on brandshatch dry. I was stuck at 9th place for ages before fuel got down to about 25%, then started reeling in the AI. I figured maybe the AI is just going slower but I noticed lap after lap I was shaving about 1/10th of a second off my best lap. Eventually getting it about 1.5 seconds faster than my best lap, despite me feeling like I was driving more sloppy due to fatigue. Is this due to fuel weight? The way I see it is fuel does add weight, or im just getting better and better by doing laps, but then tyre wear and fatigue should come into play.
Also noticed the AI seems to slow down towards the end of the race. Actually ended up being an epic race with the AI all pitting at different times, and me actually ending up 3rd which was good because my car was underpowered and got destroyed on the straights. Love it when everything just works and myself and the AI settles down on the track, it was an awesome battle. My best lap time was in the top 2% in Europe, wonder how much better it could have been had I used a leaderboard car.
In reality, it’s a factor for sure. Gasoline has a density of about 7 pounds/gallon, but I doubt that was something that was coded into the physics engine.
With sim damage I run faster deep useage of tires and fuel. It wasn’t huge difference maybe 1-2 tenths. It might more about the tires.
After doing a 45min tora races lasts night. I notice each lap used 5% fuel a lap no matter if its a full speed, ot rolling cation going 60 mph.
Thats a pretty strange “issue” as I made 100ish laps @ Le Mans with Ford GT FE 2017 (2 weeks ago) and had to pay attention at how I spent fuel since I had to pit at every 4-6 laps.
Pitting at every 6 is already painful enough hehe !!!
This is kinda one of those “Forza mystery” things that you will always hear/see different opinions on. I’ve personally never noticed any effect from it, but then I also play on a controller. I have a few friends who use a wheel that swear that they can feel the difference.
It’s difficult to test as there is no way to limit our fuel fills or change tires without getting fuel.
It’s the same kinda thing with other aspects of the game. You will hear wildly different things about fuel mileage, tire wear, aero, post-pitstop car behavior, dirty tires after going off-track, and surely a few other things I’m forgetting.
Is there life anywhere else in the universe? Why do I hate clowns? Is fuel weight simulated in FM?
So many questions no one can answer.
It’s been discussed to death over the years, but I don’t think T10 has ever given a straight answer to that question.
I run the Fuel and Tires sim and I am not that sure about the fuel but I am positive enough about the tire wear making a difference to the point on my longer hotlapping jaunts I will pit and change tires expecting to cut a killer time 4-5 laps later and 9 out of 10 times it happens too.
Yea I notice the same, the car just feels heavier in turns straight after pitting and also slides more because the tyres havnt heated up enough yet. Even if the blue is gone off the tyre symbols it doesnt mean they have reached optimum grip.
Tbh on a game that alters weight based on your rim choices, it wouldnt surprise me if they did have fuel weight in the game, weird they didnt clarify though
new tires = low pressure; usually, lowering pressure increases grip so after a pit stop, your tires should have more grip then when heated.
Why do u say the car slides more ? I’m 95% sure that :
increased contact on road from deflated tires > increased contact on road from heated tires
Bounty with P3 on Hockenheim really put the tire thing on the radar for me regarding the heat and wear of tires. I reckon as the tire showed yellow I was cutting my best laps mainly because the Porsche was digging in a bit so a little slide was a benefit. It could have been my wheel but as I got around lap 7 of every run I was on fire although by lap 10 I was ice skating so there is a pivot that needs to be taken seriously or for the sake of one lap you end up writing your name in cursive.
I like the fuel/pit set up in RaceRoom where I set up 3 pit strategies including how much gas I want to put in, fix damage etc. The downside is trying to call the pit crew via buttons/D-pad on the wheel confirm you are coming in and choose which preset all at 150 MPH can get a little untidy.
All I know for sure is that if you are driving a car built by Dodge or its siblings you will be pitting before all other brands and manufacturers for fuel. And that is actually pretty realistic. Hemi engines and the SRT-10 engine are so hilariously thirsty for what you get in return. Make no doubt about the power a Hemi engine can make but the 454 from Chevrolet running premium gas will get nearly the same hp and more torque and won’t empty its tank after three laps of lime rock.
Yes, as you burn fuel you load gets lighter and you drive faster, as long as your car is thrirsty on fuel and is good on tyers and you are a smooth driver.
I noticed that in an endurance race, my lap times were the fastest on low gas just before the tyres got above 75% wear. Then lap times got slower because of worn tyres. then I pitted and once the tyres warmed up I was back to quick lap times. This is something I believe to be new to Forza 7. At least the dramatic change in these factors. I remember doing endurance races in forza 3 and not feeling a thing.
