Just like the standard Vulcan, this model also has a completely wrong sound.
It sounds more like a modern Lambo than an AMR Vulcan. It screams and wails very loudly IRL, especially the high pitched decibels around redline are unmistakable. Look at some Festival of Speed videos to get an idea. And also POV videos on YT.
I don’t have the time to compile videos for you or do research - please ask your in-house team to do the necessary research and give this car the correct sound. Thanks!
