I spent way too long fiddling with turbo engines, then I just slapped together a NA spec engine that's down like 150hp on my turbo engines and the car is a full second faster around the test track.

Welp, guess team whatever is going to be running without snails this season.

You can get ~*massive gainz*~ with big turbos, but the lag makes it pretty worthless, especially since it seems the AI driver rarely keeps the car close to the turbo's power band in low speed corners. I've been trying to use smaller turbos that spool up earlier.

I actually managed to make a turbo engine that runs faster on the Ring than my sub 700hp NA motor, but it took a bloody 1050hp to do it, and over twice the fuel consumption.

EDIt : And given a quick fuel estimation it would have to pit every bloody lap.

Nope; this is modeled on FIA rules. Two-hour stints are a hard limit. Besides, you'd have to have some pretty incredible fuel economy to go two hours on 100L of fuel. To give you an example, a car with an engine using 400 grams/kilowatt-hour, making roughly 600 horsepower and average gearing length can expect to do something like 11-13 laps of Le Mans with the current fuel economy model, depending on the aerodynamics and drivetrains of the car, which translates into 50-55ish minutes of run time and about 150-180 kilometres.

Funnily enough, just yesterday I was thinking that your car should have at least a 500hp and at most 400 g/kwh fuel use and should go back to the drawing board if it doesn't.

Say, could you give us mathematical inept a hand to help us make a very rough lap time vs fuel use estimate?

That baby might be slow but that doesn't mean it cannot have good fuel consumption or reliability!

For my own car, well I think I have narrowed it down to three possible engines. It's difficult to choose based on power vs economy when you have nothing to compare to.

As for the design, I don't really like playing around with the car so I just took the base model and added bits as required. I will probably change the colour.



Look how happy it is!

On the first page, there is a link in the rules (as well as in one of my posts) to the track files we will be using for this simulation; a competitive car should be able to do a lap of Le Mans in something like 4:10-4:20 or so. Anything under 4:10, I would classify as very good indeed.

Power and efficiency are dependent on one another in a big way and trade off each other; do you go for high power (and good lap times) at the expense of fuel economy, or do you go for high economy at the expense of lap times? I'm kind of struggling with this at the moment; the car I posted as my submission is the high-power, low-efficiency variant, but the more I think about it, the less happy I am with it.

That's certainly more powerful than anything I have ever built.
However, when you do not have to push three tons around a track and use your tokens/quality points smartly you can get away with far less.

Nix that. The game ate my goddamn Lua file so I have to attempt to rebuild from square one.

*edit*
I crash-course recreated Gus, and is awaiting the inspection report. I'm glad I took screenshots of the engine before I closed the sandbox, because it also ate the engine design. I get the feeling Automation doesn't like it when you create a car/engine family, but leave the trim/variants blank.

To be honest it's not that great an engine apart from fuel consumption and I can't really get it higher than 500hp before it starts tearing itself apart, but maybe it is better than what you have or can learn a few things looking at it.

It sometimes also doesn't take engine changes until you test and often it will have wrong car stats until you change a part and put it back how it was.

I took a look at it, and the main thing is why aren't you using the quality sliders ? The Valvetrain slider is especially important for NA engines in this challenge to avoid valvefloat. With just that plus pushing the cam profile up to 100 i picked up nearly a hundred hp.

Did the game remove my quality points? Anyway I put mine into valve train and fuel system but it doesn't solve airflow problems in the valves.
At the end of the day I don't really care that much. I hit a pretty good V8 flat design earlier I already mentioned.

Now to see if it passes scrutineering.

If mid-engine, half a kilo too light, else that RWD is way too heavy by 149.5 kg. I would fix the negative downforce by putting it out of negative with the undertray. I feel it improves performance in the whole run. By the way, too much cooling airflow increases drag and ruins lap times.

Considering the weight of your car and the laptime you posted I'd wager you have created quite the powerful engine and you should make quite a jump forward with a better car model. Also congratulations, I am also now having to rethink entering my "economy" model because it's slower.

On the weight note: screw you MrChips, I am having troubles at times making the 1250 kg Mid-engine limit and have to put stuff in like the entertainment system to pass. Stupid game needs ballast.

I suggest you guys watch https://www.youtube.com/watch?v=Q7BQf4VD4hY about brake and esp. suspension setup.

In short: Critical Oversteer is very bad and you need to keep that small white circle on or within the red an blue line. To correct the behaviour you can change tyres and/or camber settings. The video also explains various things about brake behaviour and such you need to fix to make your car decent.

Here's my quick and dirty picture version to try and tell you to lower camber until you fix oversteer which can get you anything from a few tenths to a second.

I thought it was a minimum weight spec, not a maximum weight spec? As in your car must weigh at least 1100kg? This car is a FR setup, longitudinally mounted v8, RWD. My car is over the 1100kg minimum, and if so it's just a (self-imposed) penalty that it weighs more?

Remember this is a huge estate chassis - I don't care that it's huge and less competitive than a sports car chassis, I want my Touring Car Championship damnit. ;)

That's the intention; building your car, then using interior and infotainment systems and their associated QPs to ballast your car to the minimum weight. There is no restriction on QPs in those two categories for that exact reason.

Also that suspension advice is good :)

I might actually have that version now that you mention it; I'm away from my computer until late tomorrow and all I had to go by was the Steam news feed for the game, which I'm pretty sure is wrong.

Even still, there might be a difference between the standalone and the Steam version; I remember reading that when the first Steam version came out a couple months ago, they had to branch off to make it work properly. Additionally, the standalone didn't get updated with the newest content until.very recently.
