GM fans though we may be, we wouldn’t refuse an AMG E63 S were we given the keys. The sporting sedan packs a 603-horsepower punch, courtesy of a twin-turbocharged, 4.0-liter V8, and ships with all-wheel drive. However, if it were our own money, the CTS-V holds one very important, practical advantage over the AMG: a $20k lower price tag.
At the end of the day, though, maybe it’s a bit silly to mention practicality; nobody really needs a high-powered, boosted sedan with over 600 horsepower. You buy cars like these for the vibrant thrills.
With all that said, click play to watch Jonny Lieberman and Jethro Bovingdon pit the two against one another on the track, in instrumented testing, and on the road, in an effort to find out which is a more thrilling performance sedan: the CTS-V, or the AMG E63 S.
