Wow, it got deleted already. It seems they are ignoring all evidence.

Give me a couple days to a week to dig around for additional information. Based off pictures alone, we already know it’s incorrect:
In Game:
In Real Life:
Suspension is far too low as well, it should be sitting up higher and there should be a large gap in the wheel well between the body and the wheels.
This video shows just how tight of a turn the chassis can make: https://www.youtube.com/watch?v=1efBGGThZeM at 2:07. I don’t know Chinese so IDK if they are saying anything about it’s performance.

This would probably be a good photo to compare with the model.

The video does not talk about its turning performance at that time, it instead is talking about the professionalism of drivers. However, the most likely way to getting this issue fixed is probably hoping somebody else will review the bug report, somebody who won’t be picking bones with every assumption necessary.

The video provides the demonstration of it’s potential turn radius.
But the real requirement for fixing the turning radius is the angle of the front wheels and the length of the wheelbase.

Okay, did some modelling in Blender since they keep denying their modelling is off, and here is what I got:
Front wheels can turn max of +/-30 degrees, anymore and the wheels will hit the front lower plate. Particularly of note is that the front chassis is thinner than the rear, makes sense though since the rear wheels do not need to turn and is often where soldiers are carried in the IFV versions. Second wheel set can turn just as much as the front but I have never seen them actually do this and are limited to +/- 20 degrees.
Here are some photos of my model (built off of orthographic views of the ZTL-11 + photos I got from your video on the raw chassis, thanks!):
You can see the wheels match up quite nicely, so I am fairly confident in these wheel angle limits.

I did some calculations, and it seems that +/-30 degrees can provide turning with a radius of 10-12m, so the wheel turning angle should be correct and agree with the source.
I also noticed that in the photo below, there is a huge angle between the wheel track and the direction the front wheel is pointing. Is this where the gaijin got wrong? I estimated that according to the picture, the turning radius should be about 13.5m.

What is the wheelbase in this case? I seem to have found an indirect wheelbase information
Wheelbase from the model I made is 4.9m. Here is my bug report on this issue: Community Bug Reporting System finally had some free time to gather all our information and make an argument for it. Next up is to get the reverse speed fixed…

Oh, I wrote the wrong word, it should be wheel track. How many is the wheel track of your model? and can you measure the wheel track of the model in the game?
Wheel track should around 2.3m. I would not be able to measure the in game model without having a copy of their model I could open into Blender. I imagine theirs is a bit larger since the model looks a bit chubbier
There is a master’s thesis of BIT in 2018.
8×8 轮毂电机驱动车辆转向稳定性控制策略研究
They got an 8x8 wheeled IFV from the manufacturer for modification and experimentation.Although the research project may be worked for the new 8X8 chassis,the vehicle for modification, judging by the photo, should be ZBL08.
There is a table that lists the parameters of the experimental platform.The thesis states that the parameters are from the manufacturer.
Since it is a modification on the ZBL08, and not a newly made experimental car, then I think that there should be no change in parameters such as the wheel track.
In other words, this circumstantial evidence may indicate that the distance between the center lines of the two wheels should be 2600mm.I don’t know why your model is still a little smaller.
Do you measure the track from the inside or from the centerline?
I took it from the insides of the tires, not centerline. Measuring centerline in Blender is a pain and the reference image I was looking at for wheel track I thought it showed from the insides of the wheels. But yes, from centerline of wheels 2.6m would match what I have:
Also, rejoice, the bug report got acknowledged status!

Yes, that’s a match. I bet the wheel track of the model in the game must have been narrowed.
Congratulations! Hopefully, you don’t get sniped by that guy. the problem will be resolved soon.
