I believe it's all the tires' fault. I can hardly ever hear my engine, unless windows are down and I'm really gunning the car. Road traffic noise has been tremendously reduced compared to my 2012 PIP. Also, you have a lot of different noise characteristics depending on the road surface. The smooth, new asphalt surface on some of the freeways is noticeably quieter. If you're running on electric at that time, you can hear a pin drop inside the car!!. The Prime Advanced really offers an excellent Stealth Mode!
. I really wish we could get noise cancelling technology out of Toyota; now that would be truly revolutionary since it should obviate the need for so much heavy insulation.

Thanks Henri. Good report.

Is the noise all the tires fault? Or is the Prius also lacking some sound insulation? Is the new Prime quieter than the regular Gen4 Prius? I just came back from a nice morning drive, and my Toyo tires were very noisy on just about every road.

Other than that, it's a very nice car to drive. Looking forward to the day when I can put on a new set of Michelin defenders.

I would think twice about the defenders. They're comfy and quiet, but kiss the 50+ MPG bye bye. When I had the defenders on the gen 2 I got about 32 MPG when I usually get 40, so I returned them. Big difference IMO. I still haven't had a good set of eco tires. My gen 2 is riding on Yokohamas right now and the MPG is pretty good, but they are pretty noisy still, especially compared to my gen 4. Nice to have you back CoastCruiser!

Page 311 of the owners manual implies that the OEM tires on the Prime are not designed to go over 85 mph.

Not really. It gave Toyota the flexibility to spec OEM tires with an 85 mph speed rating. The Toyo NanoEnergy tires most of us have as OEM tires are speed rated "S" to 112 mph/180 kph, I believe https://www.tirerack.com/tires/tires.jsp?tireMake=Toyo&tireModel=NanoEnergy+A29&sidewall=Blackwall&partnum=965SR5NEA29&tab=Specs

That said, there are plenty of good reasons to avoid going over 85 in a Prime (or any car)
