2016 Cadillac CT6: What's New, Specs & Features
Last updated August 4, 2026
The 2016 Cadillac CT6 is an all-new model and the first year of Cadillac’s flagship sedan. Its headline change is the debut of the rear-drive Omega platform with an aluminum-intensive structure.
About the 2016 Cadillac CT6
1st generation (2016-2020), first year / all-new launch.
Cadillac positioned the CT6 as a prestige sedan that combined full-size passenger room with lighter weight and sharper responses than a traditional big luxury sedan. The core pitch was not just softness and status, but a modern flagship that felt more agile, used advanced chassis technology, and brought headline technology into a roomy four-door. For most shoppers, the CT6 was the brand’s tech-forward flagship sedan with real rear-seat space and a more athletic feel than its size suggests.
Cadillac positioned the CT6 as a lighter, more modern kind of large luxury sedan, with a rear-wheel-drive 2.0 Turbo at the entry point and two V6 engines paired with AWD. Premium Luxury trims stand out for a 12-inch digital gauge display, a head-up display, and a rear camera mirror. Platinum models add richer rear-seat accommodations, massaging front seats, advanced chassis hardware, and a 34-speaker Bose Panaray audio system.
What changed, by category

Three engines launch with the new model: a 2.0-liter turbo four-cylinder with rear-wheel drive, a 3.6-liter V6 with AWD, and a 3.0-liter twin-turbo V6 with AWD. Every version uses an eight-speed automatic, and the V6 models include Cadillac’s active chassis software.
Styling
The CT6 arrives with an all-new exterior design and LED high- and low-beam headlights as part of its core equipment.

The new CT6 centers its cabin around a 10.2-inch touchscreen with Apple CarPlay capability, Bose audio, and active noise cancellation. Higher trims add features such as a digital gauge display, a head-up display, a rear camera mirror, rear-seat entertainment, and a 34-speaker Bose Panaray system.
