Generally, Chrysler has speed limiters that match the OEM tires — and this has been the case since at least the 1990s. Not sure about before that. valiant67 pretty much said this. I've seen it with the same model having different speed limiters for trim levels with different tires... and that's the extent of their liability for the most part. The only other reason for speed limiters that I know of, in cars, is if a component other than tires is not able to handle the speed — e.g. it redlines the engine (not likely! but in the Ford Thunderbird SC I drove, not owned, if you went over around 130 mph on the speedometer — not sure if that was accurate! — it would downshift and go over redline, which is just about the same problem). Aerodynamic lift is another possibility though I don't know of any examples there. The video of crashes at the Ring shows that at very high speeds, tiny mistakes yield huge problems very very quickly. I have exceeded 100 mph many times and now I am thinking that was a huge mistake... but I'm still here, no thanks to Young Me’s lack of wisdom. On trucks, sometimes they set relatively low top speeds to match the desires of fleet buyers. They might do that on cars, too, I don’t know. If it was a matter of liability, SRT cars would be top speed limited.
