https://jalopnik.com - This CT6 V-Sport is finally the proper kind of flagship that the Cadillac lineup needed. The regular CT6, even with the top-level 3.0-liter, twin-turbo V6 and 404 HP, never really cut it, in my mind. Driving it, I found it to be quick and agile, but not fast. Not exciting. Part of that was because it didn’t have a powerful V8. It needed a powerful V8. And now it has a powerful V8.
