RPM's

As you can see from my signature, I have a 2017 Grand Cherokee V6. While in Park or Nuetral, when I rev the engine the RPM's do not go above 3000. Is this normal for the 2017 V6? I don't remember having a rev limiter on my previous 2014.

Re: RPM's

I believe they all have a rev limiter that is much below redline when in neutral. Better question though is why are you revving your engine so high, or why would you ever need to do that?

Reason I tested that was because of an experience I had yesterday using my paddle shifters through the first 3 gears. Yesterday, as I was driving home with the family from our annual pumpkin picking trip, I noticed there is a slight pause in acceleration at exactly 3000 rpms when using the paddle shifters. Example: Light turns green, while using paddle shifters and while in 2nd and 3rd gear, as the rpms reach 3000 and with your foot still on the accelerator to drive up the rpms, anything over 3000 you will notice a pause in rpm increase for a split second before continuing passed 3K....I went up to 4K. I would never even go near redline using paddle shifters or in manual mode (I usually don't go passed 4K). So this morning as I parked at work, I thought that I would rev it a little passed 3000 rpms as a test, and long behold the rpms did not go passed 3000 no matter how far I pressed the gas pedal. I wonder if you can try this and let me know if the same thing happens to you As I stated before, my 2014 Limited, with the v6, did not have the rev limiter. So I'm guessing the rev limiter was added to the 2015?

Re: RPM's

It's a pretty common thing on all new vehicles with electronic gas pedals (drive-by-wire). Wasn't that easy to do in the days of cables opening the throttle plates, but now a little motor (servo) moves the plates, based on what the computer tells it to do, based on many inputs (including the gas pedal position).

Don't worry, you didn't hurt your engine at all. You can pretty much drive any new vehicle any way you want, right off the lot, without doing any damage. "Careful, meticulous, new engine break-in" is a thing of the past.

Thanks for responding, I thought that was the case (although I'm pretty sure my 2014 wk2 did not have the rev limiter). Can you try my paddle shifter test regarding the pause at 3000 rpm?

Re: RPM's

I've never noticed any pause while accelerating through 3000 rpm with or without using paddle shifters (I drive hard, so my gas pedal is often floored, and I routinely hit 5000+ rpm). Keep in mind that I have the 5.7 V8, so we don't have the same engine, or even the same transmission.
