The CarStats template is currently being worked on for Forza Horizon 4, but will function exactly like for any other title. The example below is for Forza Horizon 3, but the parameters will be the same for Horizon 4:
You're free to already fill in the above shown parameters, as they will be accepted once the template is updated. As for the division parameter, try using the division variable names for Horizon 3 that are shown in the documentation. Some divisions may not be in Horizon 3, so you might need to come up with new variable names (we prefer using abbreviations for variable names).
Unfortunately I'll be unlikely to work on the CarStats template soon, as I'll be gone from home for the next two weeks. However, I'll try to check on the site on every possible occasion for questions and patrols.
I've altered the CarStats template and added FH4 functionality.
At the moment, all championships are the same as FH3 and will be changed if needed upon game release. There is also a ForzaThon Store parameter for FH4 that will replace "Purchase from the AutoShow" with "Purchase from the ForzaThon Store", and will also replace its Credit value with ForzaPoint value.
I've also shuffled the DLC and other parameters around to better group data between what's required to own the vehicle, what the vehicle uniquely offers, its rarity value, and to better distinguish it from the more in-depth tuning data.
I assume something is breaking the CarStats template on vehicle pages. I'm getting lots of errors in the Traffic section. I had a coworker look and he was too. The template is more complex than I generally work with, but I assume guys can certainly fix it! I saw it here - Ford_FPV_Limited_Edition_Pursuit_Ute. I'm using Chrome, so if you don't see it, try that browser.
Awesome. Thanks! Question - where do I find a vehicles division in the game? I am looking at the Division section of the CarStats template (documentation) under Forza Horizon (Body Style) and the Titan Warrior Concept Forza Edition (my favorite vehicle in the game so far - truck gal - wish I could afford the Titan Warrior in RL) doesn't seem to fit any of those options.
I don't know if there are any division/championship categories for cars in Horizon 4 yet - I'll be able to find out in 3 hours - but the selection we have for Horizon 4 is copy-pasted from Horizon 3, so it doesn't matter at the moment what you add to the articles as we don't know what to expect ourselves.
If you're having another look, watch out for something like "Offroad", "Concept", or "Modern Offroaders" accompanying the Titan Concept in the menus.
