Metallic Vibration/Rattling/Buzzing At High Speeds

[Mattsraptor 2025]

Here's one for the group gurus......

Anyone got an idea what could be causing the vibrating metallic sound in the clip?
Starts about halfway through.
2024 RR V6.

Sports & Normal Mode 4A & 2H. Occurs when accelerating from about 160km/hr through to 175km/hr. Eases off beyond this, however returns when decelerating through the same range and is not present below the 160.

Sounds like it’s coming from within the cabin or underneath and in front/behind the dash - drivers side.
Have had a look underneath and nothing obvious…..heatshield, bashplate etc.!

I mean how often are you actually going that fast... These trucks aren't really built for that high speed. Considering they're factory limited around 180km/hr.

True, but it’s not the point.
A new vehicle, any vehicle, shouldn’t make that sound while driving!
