I love my 05 Deville's ride but I was curious to see how these newer cars ride so I test drove the 2014 Chrysler 300C AWD Hemi, 2015 Hyundai Genesis 3.8 AWD and 2015 Cadillac XTS AWD. Afterwards I decided I'm going to try to keep my Deville going for as long as possible. The 300C had the best ride of the three. It was firmer than my Deville but it absorbed bumps quite well. I loved the power of the hemi and often found myself going much faster than intended. The Genesis rode more firmly than the Chrysler and I felt impacts more but it was tolerable. The 3.8 was smooth and responsive with a nice little growl. I really wanted to like the XTS but I was disappointed. The ride was the worst of the bunch, jittery even on relatively smooth roads and large impacts were felt and heard more than in the Hyundai and Chrysler. The Cadillac's engine sounded and felt more coarse than the others. Driving these cars made me love my Deville even more.
