The CT6 is closest in its dimensions to the Mercedes S-class. Wheel Base - CT6: 122.4", S-Class: 124.6". Overall Length - CT6: 204.1", S-Class: 206.5". The weights differ, Base CT6: 3,666 lbs, S-Class: listed as 4,630 lbs in both RWD and 4MATIC (AWD), The S63 is listed at 4,806 lbs. The S560 has a 4.0L Twin Turbo V8 rated at 463 Hp/ 516 lb/ft Torque. Cadillac wins there.... The S63 (equivalent to what a CT6-V would be) also has a 4.0L TT V8, but its turned up to 603 Hp/664 lb/ft Tq. Mercedes wins there, depending on what the actual weight if the CT6 V Sport is compared to the base model.

I've actually been shopping the CPO market for a 2016 CTS-V vs. a 2014 MB AMG E63 S. Two great cars to buy used because of the massive depreciation. Even though the CTS-V is lighter and has more power, it's pretty much a no-brainer to go with the AMG for me at least because of these other factors.

1. MB CPO warranty is so much better for DD car (unlimited mileage).
2. You get treated like you expect to be treated when you bring the car in for service
3. Blizzaks + AWD for the winter (and you can turn it off when you don't want it on).
4. The MB is way classier inside and out than the Caddy
