So far so good. I have 1600 miles on it already (I commute 90 miles a day round-trip to work). I am actually getting about 28 mpg on the highway. In town around 21. Better than than the sticker said. Like the Genesis, regular unleaded is what I have been using. The twin turbo feels very strong at highway speeds. I have not had any glitches yet (knock wood). The center console will easily hold 15 CD cases and still have room for my ipod and misc. stuff. The bluetooth is nice in that it displays the phone book from my phone so I did not have to enter any numbers into the car. I really like the seats in the Volvo. The bottom cushion is a bit longer and feels right under the thighs. I really like the ipod integration and the ability to randomly shuffle songs from the Volvo end without having to do that from the ipod itself. The volume of the ipod/usb is louder than FM/AM/CD so when switching from one of these to ipod, it can startle you if the song playing is loud. I was not going to get the Tech package on the Genesis. I am really surprised about how good the HD radio sounds. I have quite a few HD cannels to choose from here and they all sound great!!! Much better than SAT. I discovered that we have AM HD channels here too and they sound amazing, not unlike regular FM. I really think Hyundai should include HD radio across the board. The Volvo has a really dialed in feeling of "straight down the road." Crowns and angels do not seem to move it off of its intended path. I really like the controls for choosing where the ventilation will blow from...maybe the best I have ever experienced. Any combination of top, bottom, and dash can be chosen. The A/C is very powerful. This is also the first car I have ever had that is virtually dead-on with regards to both mpg and miles-to-empty. The brakes are fantastic as is the ride. It just seems to "step-over" road imperfections.
If I had to nitpick some things, I find the power windows to not be as smooth or quiet in operation as the Genesis. I really wish it had the keyless operation that the Genesis has. I also wish it had the power tilt/telescope steering
wheel feature that the Genesis has. The storage pockets in the doors are not as nice as the ones in the Genesis. The trip computer only has a single bank. (My Passat had two, so you could keep one accumulating and reset the other). I am not sure how Genesis does this. It does have two trip odometers though. The S80 has no engine temperature guage at all (I like full instruments). It uses an LCD bar to indicate fuel level that is not as easy to read as a guage.
Yesterday, I dropped the car off so that the dealer could install the mud flaps, give me the rubber mats, and replace the license late frame (all at no charge to me.) They gave me a loaner S80 that had 21K miles. It was only the 3.2 non-turbo FWD. It got about 30 mpg on the highway, but, the difference in power compared to my T6 model was dramatic. Besides the power difference, at 21K miles it was still tight as a drum and really solid feeling. At 21k the leather barely had a crease and looked like it will wear really well.
I hope mine holds up as well as the loaner I had. It is interesting the different approaches and compromises that manufacturers make. I am overal quited pleased so far.
