Rough idle by nature?

Hey guys, last night I test drove a brand new 2015 diesel. Overall it definitely felt like a more v6 with more torque, but very drivable that's for sure. I really liked it but did not like the idle. It seemed to vibrate everything a lot more than the V6 - like 100% more than the V6.

Did you guys notice (when you first purchased) a more rough idle? Is that by nature of the diesel?

Thanks for the input.

Gotcha. Just thought I would ask. Tons of benefits, but that must be one of the small downsides.

Yep it's a diesel. I have also read in reviews and experienced myself that the GC diesel does indeed idle a bit louder and more rough than say an X5 with a diesel.

Re: Rough idle by nature?

The BMW X5 diesel motor is a straight 6.
Straight 6's are inherently more balanced than a V6, hence the "rougher" idle in our VM Motori engine.

Re: Rough idle by nature?

I would have to say though, for the GCs motor being all new it's a great one. It just has a typical diesel cladder, especially noticeable at idle. I still really like it though.

Agreed. It seems pretty civilized compared to the 5.9 Cummins in my Ram though.

We just traded a 2013 X5 diesel in on a 2015 Summit Diesel and in our case the Jeep is a whole lot quieter and smoother. I've read the Summit has some fancy noise cancellation system (how do you even know that is on? LOL) but even externally the X5 was noiser at idle, even when it was new. Noise doesn't equal vibration, but the same is true, the Jeep seems better. Maybe our X5 was an oddball.

Re: Rough idle by nature?

I was a little surprised the idle quality wasn't a bit nicer. If you pay attention, you can feel it in the steering wheel as well.
