Ok so a few days ago when I was at an ATM i stopped and revved my engine, i could hear a whining sound like bee/supercharger type. It gets pretty loud when i revv the engine and you could hear it whine down as the rpm drops. Now I put it in Sport mode and on drive and when I hit the gas I could clearly hear the whining noise even in the cabin, specially when I let off the gas and let the Sport mode keep the revvs up high. Anyone know if this is normal??

Pretty sure it has done this since I bought it, but I always have music on so maybe that's why I didn't hear it til now.

 

Mine does that too, I hear it whines when I floor it, sounds like a supercharger and I liked it!

 

akuma88, did you find out what the problem was? i noticed the same sound when i test drove a '13 GS yesterday that i'm planning on buying on thursday.

 

Mine does it too! Pretty normal I guess. If I recall my Camry made a whining noise too. Maybe it's a Toyota thing. Idk.

 

It's normal Toyota engine sounds guys, just floor it.

 

Mine does it too... my dad's GMC envoy does... buddies charger does.. but my tacoma does not. i honestly cant explain it. It's strange that you can only hear it from outside, not in the drivers seat, and i dont notice it with the windows down...

 

Sounds like it is normal from what other people have been saying but I had a issue in a different car with a tensioner pulley that was going and it would make sort of a whining/high pitched sound when revving the engine, it would get worse the higher you revved it.

 

Normal. It's also the reason why a lot of people mistake the GS for being supercharged, but we know better...

 

We know IT IS supercharged, Toyota just wanna remain low key and keep telling us it's a N/A motor.

 

They did an excellent job of camouflaging the supercharger and masking its power!

 

They sure did. I can barely hear it over the clacking noise the DI makes.

 

Call CHEATS! Toyota was the best at it.

We all know it's supercharged anyway, the fuel consumption gives it away

 

WHAAAT it aint supercharged !! False sound advertisement. J/k with the exhaust it is way more pronounced.
