“The Super Cruise is a great start towards a self driving car. If you do a substantial amount of long distance driving, it's a great option to have. The Blackwing engine is incredible.”
2019 Cadillac CT6: What's New, Specs & Features
Last updated August 4, 2026
The 2019 Cadillac CT6 gets a substantial mid-cycle update led by redesigned front and rear styling. Cadillac also installs a 10-speed automatic throughout the lineup, reorganizes the trims, and adds a Blackwing twin-turbo V8 later in the model year.
About the 2019 Cadillac CT6
1st generation (2016-2020), mid-cycle refresh year
Cadillac positioned the CT6 as a driver-focused flagship sedan: a large luxury car with full-size room and high-end technology, but a lighter, more agile feel than the traditional big luxury-sedan formula. Cadillac leaned on the CT6’s aluminum-intensive structure, available Super Cruise, and broad engine range to sell it as American luxury with real road feel. For most shoppers, the CT6 is the brand’s technology showcase and long-distance luxury sedan with stronger driver appeal than its size suggests.
The 2019 CT6 lineup ranges from comfort-focused Luxury models to the darker-trimmed Sport and richly equipped Platinum. Notable features include a 10.2-inch touchscreen with Apple CarPlay and Android Auto, Super Cruise hands-free highway driving on Platinum, and massaging front and rear seats in the top trims. The 4.2 Platinum pairs those luxury features with the hand-built Blackwing twin-turbo V8.
What changed, by category
Styling
Cadillac redesigned the CT6’s front and rear. The new Sport trim adds a black mesh grille, front splitter, rear spoiler, and dark window trim.
Powertrain
A 10-speed automatic replaces the previous 8-speed throughout the lineup. A turbocharged 2.0-liter four-cylinder becomes the standard engine on lower trims, while the 4.2 Platinum adds the Blackwing twin-turbo V8 later in the model year. The plug-in hybrid leaves the U.S. lineup.
Safety
Super Cruise hands-free highway driving becomes standard on Platinum. On 3.6 Luxury, automatic high beams, blind-spot monitoring, and lane-departure warning move from standard equipment to optional equipment.
Tech
On 3.6 Luxury, navigation moves from standard equipment to optional equipment. Ventilated front seats also change from standard to optional on 3.6 Premium Luxury.
