I drove the 3.0 first but then had to wait until my 4.8 came in to see how it compared. I feel that the 4.8i with the sport package rides very well. There is definitely more roll and less compliance with imperfections in the road without the sport package, EDC, etc. The ride has 19" wheels which I thick will have a smoother ride than the 20" although the 20s look great. When in sport mode, there is some increase in the rougness of the ride but not significant. I also have active steering and am getting use to it and am glad I got it. The 3.0 I drove did not have it. In my opinion the sport package would be a must to make me happy and is well worth it!!!
