Logic would dictate that a mid-sized wagon would exhibit different driving dynamics than a mid-sized sedan. And logic would be right, but not by much. Whether on a residential street or a race track, the CTS-V Sport Wagon feels exactly like the CTS-V sedan. You would have to drive both back-to-back to really suss out the differences. It's that close. Turning is just as sharp; weight transfer is similar. If you didn't peer into the rearview mirror, you wouldn't know you were driving a Costco-mobile.
