About the 2017 Cadillac CT6

1st generation CT6 (2016-2020), second model year, before the later tech-focused updates and refresh.

Cadillac positioned the CT6 as its flagship sedan: a large, roomy luxury car with advanced technology and a lighter, more athletic feel than many traditional full-size rivals. The core appeal was space, quiet comfort, modern cabin tech, and confident road manners, with the CT6 meant to feel like a prestige sedan you would want to drive yourself rather than only ride in.

The 2017 CT6 lineup ranges from straightforward turbo-four and V6 models to comfort- and technology-focused Premium Luxury and Platinum versions. Twin-turbo V6 models pair stronger acceleration with AWD, while Platinum trims add features such as massaging front seats and ventilated rear seats. The new Plug-In serves as the technology-led model, with navigation, a Rear Camera Mirror, heated and ventilated front seats, and dual rear entertainment screens.

What changed, by category

Powertrain
A new CT6 Plug-In joins the range with a 2.0-liter turbocharged engine, two electric motors, an 18.4-kWh battery, and rear-wheel drive. The gasoline engine lineup is largely unchanged.

“The ride is very smooth and the car is easy and fun to drive. The technology in the car is easy to learn and use. It gives a great level of comfort when you are driving alone or with others in the car to know that if something unexpected happens the car will stop itself and prevent an accident.”
