Last week when I was driving on the highway, I could hear a very high-pitched sound when in an aggressive acceleration. i.e. the engine in high rev. I’m not sure about the rev as I was in normal mode, so it’s not displaying on the dashboard. But the sound made me feel the car is turbo-charged while it is clearly not.
So has anyone had similar experience?
Is it normal or I should be concerned?
Thanks in advance.

I, recently, when the weather was hot (35 celsius) on the highway. 3rd gen, so likely not something 4th gen-specific (the cars share a ton). No ideas what it is/was. 395,000km on the clock.
