I test drove a JX a while ago, and it didn't have a loud roar.... but last night, driving an AWD QX60, the engine roar was too loud for me. I asked the SA if this was "out of spec"... but he said it was normal, and that it was a "good roar"....

are QX60s louder than JX35s?

or was it the AWD?

I dont' think I can get used to this roar....

I just purchased a QX60 and test drove a JX35 before I bought it. I don't remember the JX being quieter in terms of engine noise. I will note that of the major sources of noise - engine, wind and road - the QX60's insulation for engine noise seems to be the worst of the three. The QX60 is fairly well insulated for road noise, ok for wind noise, but you do hear the engine. With all that said, I think most Infiniti products have an engine noise issue. The only ones I think do not are the new Q50 and the QX80 (QX56).

I test drove the pathfinder as well, and I don't remember the pathfinder being that loud...

maybe it was just 'that one' qx60 I test drove.... also, i had the qx60 in sport mode during the test drive, maybe that had some effect to the engine roar as well....

My guess is combination of sport mode, plus you were probably accelerating hard. It is only at high RPM's that I notice engine noise from any JX/QX60. And yes, they're the same - JX and QX60. Any JX on a dealer lot these days is going to be identical to a QX60, other than the badge on the back. The window sticker may indicate slightly lower fuel economy on the JX, but they're the same unless the JX was built before May, 2013.

a big contributer to the engine roar will be the CVT system, under acceleration the engine spools up essentially unburdened by the CVT as it selects its 'ratio' that could simply be what you're hearing....

That's what i noticed with many CVT-equipped vehicles I driven over the years. I originally thought it was an issue but it's of the norm for CVT's

so to avoid the roar sound, one should simple use a lighter foot when stepping on the gas?

I did notice a little less roar when the drive mode switched back to 'normal'....

A bit of a noob question. I've seen many references to the CVT being noisy. Is it that the transmission itself makes perceptible noise or that by the nature of the CVT's operation, there is increased engine noise?

Its the nature of CVT. because it doesnt have gears to flip through it needs to search for where it needs to be. a CVT is basically fluid and a belt, depending on how hard you accelerate it will select different ratios. Under hard acceleration it takes a second to decide where it should be, which lets the RPMS soar as the CVT becomes disengaged...

Quite possibly, it's always best to have driving habits like that, the smooth transition into different speed levels will help
