Put about 50 miles on her on a hilly country road. Drove 5 miles between 40-50 and did not hear any drone or baffling noise.
8 speed is seamless and you can hardly tell it is shifting unless you really pay attention. I was skeptical on how much it would matter, but initial impression is it is a significant upgrade.
Very quite and smooth ride. Not sure where the phone speaker is coming from but it sounds like an AM radio when making Calls.
It rides smoother than my 2013 with 20" tires. Definitely quieter. Time to go for another drive!
Finally congrats, oh check if the dimer for the air condition goes down when you talk with the phone.
