    Hey Everyone,

    I have a question about my 2009 DC 4x4. I've had the truck only a month (42xxx miles, bought used) and have always been curious about the sound of the engine at around 2000RPM while accelerating. It's hard to hear, but I've attached a .zip that contains a .wav I recorded. You can hear it best at around 3 seconds and again at 8 seconds.

    The best way I can describe it is a "moaning" sound. Is this normal? It only is noticable at 2000 +/- 100 RPM. It doesn't seem to be affecting performance because when I get on it, I am able to hit 60 in about 6.5 - 7 seconds which is within spec. Also, this sound can be reproduced when the car is in park if I rev it to that 2000 mark.

    Anyway, take a listen. This is my first Taco so I don't know it's idiosyncracies yet.

    Thanks!
    Adam

    EDIT: Oh yeah, and if this is a normal sound, does anyone know what makes such a sound?

    Sounds normal to me too!

    I went from a 2011 F150 5 liter V8 to my Tacoma V6. The Ford was super quiet and I thought the Tacoma was noisy at first. After driving it for a few days I now think the Tacoma sounds perfect!

    If that is moaning to you, I'm curious what your girl sounds like. :p

    I think 2000 rpm is about where the more aggressive VVT-i cam timing kicks in, so the engine sound changes. Keeping the revs below 2000 rpm when cruising will save fuel.

    Mine didn't come with this...even though I asked. Although I would like to see more. ;)

    She's not a moaner, she's a screamer. ;)

    I figured it had to be something like that, and that makes total sense. My previous car, a 2006 tC also had a change in engine note (2AZ-FE) but it didn't happen until about 3600, but of course that was a two door car and not a truck. The sound was different, but definite. In the Taco, I generally keep it below 2000 at all times and really around 1500-1700 for around town cruising, traffic permitting (edit...and so far I've averaged 19.5MPG with little higway miles). Although rarely, I will just give it a good lead foot to hear that awesome 3000+ RPM roar of the 1GR.

    Either way, anyone who complains this truck is noisy needs to buy an Avalon...or a Camry. It's a truck for god's sake and I love the sound. I'm just glad it's normal. :)

    Thanks for the replies!

    I'm still trying to get used to my truck's sounds, since I've only had it for almost 1400 miles. My previous ride was an '05 Ford Escape, and its engine was much smoother than this one. Not complaining, but it's noticeably louder.

    Nice angle on the vid.

    I always like seeing the suspension in action.

    What do you have the camera mounted to? I am guessing by the sound thats a gopro?

    Sounds normal. Sounds like you have an exhaust to me.

    I also feel it sounds louder and noisier in the cabin since I came from Lexus rx450h but I know what I got into when I decided to buy it.
