Test Drive Reviews

2017 Cadillac CT6

Cadillac hasn't had a proper flagship sedan for a number of years. For a brand that's trying to set itself up as a real contender in the global luxury marketplace, this is very bad. But the brand has been quietly working on one behind closed doors for a few years and, in 2015, they revealed the finished product called the CT6. But being a flagship sedan, it faces quite the opposition from German, British and Japanese rivals who have been playing in this segment for quite a while. Can Cadillac make any inroads with the CT6?
