    Hi, could someone explain please how a car's top speed is determined after applying a certain tuning kit? I know a (base) car's top speed can be found readily inside the CAR_PHYSICS_DATA table as Top_Speed_kmh. CAR_PACKS links cars with tuning kits and contains for each link override values for acceleration, braking distance and handling - but not for top speed. The tuning kits themselves, defined in AFTER_MARKET_PACKS, are not car-specific and have the following properties: Speed_ratio Power_ratio Acceleration_ratio Free_ratio CX_ratio Weight_ratio Suspension_ratio Braking_ratio The table definition suggests all these can be decimal, although all but power ratio happen to be integers, some negative. My question is: how can I calculate the resulting top speed when applying such a pack to an applicable car? The Top_Speed_kmh field of a car's physics data is in TDUF Database Editor located inside the Tuning tab, which isn't a real tab in the database itself, but it suggests the tuning relevant parameters might be contained to this tab. For completeness, these are: Gravity_Center_Length Gravity_Center_Height Drag force Downforce Top_Speed_kmh coef_grip coef_overturning coef_accel coef_brake BrakingDist Handling coef_suspension coef_sharpness Which of these combine with which fields from the after pack in what way to update the top speed? Thank you in advance for any insights!

    I have indeed reached the dev now and want to share what I've learned with anyone else who is wondering. It turns out that this came down to a typo in the spreadsheet I found. We can indeed expect the Spd stat and top speed to be monotonic. For the car in particular, at tuning level 3 it was Spd=88, not 78. There are about 30 other cars in the sheet whose speed stats suspiciously often contradict top speed relative to other cars in their class, which strongly suggests these are typos as well. There could be typos in other columns which cannot be cross-validated from redundancy as well. I'll try to extract the car stats from the game files and if that doesn't work, have to collect the data manually very diligently if I want correct data.

    Hi andrey! I appreciate your response and detailed context about the CTS-V in particular, but unfortunately that doesn't answer my actual question. Inside the game, how can one car have higher top speed than the other according to the SPD stat, but the other has higher top speed than the one according to the top speed stat? If the two are supposed to tell the same thing just in different units, this should be impossible. I hope I phrased it more succinctly this time.

    Hey! Apologies if that's been asked already, but going through the cars stats at various tuning levels I found a curiosity that I can't quite make sense of myself and hope somebody can explain what's going on: There are a few instances where car A has a higher "SPD" stat (the one on a scale from 0 to 100) than car B, but car B has higher Top Speed (the one in absolute units, mph or km/h depending on metric settings) than car A. The particular example I stumbled across was according to Gee Tee's spreadsheet: Cadillac CTS-V with Cadillac tuning at level 2: SPD=81, VMax=244 Cadillac CTS-V with Cadillac tuning at level 3: SPD=78, VMax=255 I haven't found the car in game yet, but trying to plan ahead this has really confused me about which of the two stats to base decisions on, or understand whether there is a nuanced difference between what the two are exactly saying. Some of the values are missing in the sheet as well and I can't verify yet whether those stats match the ingame values in this particular case, but from the cars I did encounter so far it seems like everything has been parsed faithfully. So is this a data collection error, if yes does anybody have a more complete spreadsheet with the car stats, if no what does such a discrepancy mean exactly? Thanks in advance for any kind soul helping to clear that up!
