Consumer Reviews for the Cadillac CT6
Read recent reviews for the Cadillac CT6
Fantastic voyage
Deborah, 04/14/2018
2018 Cadillac CT6 PLUG-IN 4dr Sedan (2.0L 4cyl Turbo gas/electric hybrid EVT)
I absolutely love this car. I have owned 6 cars and 3 SUV's and the CT6 hybrid is by far the best. The ride is incredible. The ride is so smooth it feels as though you are floating. The seats hug you as you drive and it feels as though they were made just to fit your body. The technology in this car is amazing and surprisingly easy to navigate.
