First Generation (2016 – 2020)

The first-generation Cadillac CT6 made its debut at the 2015 New York International Auto Show as a 2016 model year vehicle. It goes on sale in late 2015.

The vehicle uses an all-new, rear-drive vehicle architecture known within GM as the Omega platform.

Before Cadillac officially announced the name of the CT6 while revising the entire nomenclature for its lineup, it was widely believed by enthusiasts and the media that vehicle was going to be called LTS.

Discontinuation In North America

Following GM’s decision to produce its new line of large electric vehicles at the Detroit-Hamtramck Plant, the automaker confirmed the discontinuation of the Cadillac CT6 in a memo sent to plant employees in December of 2019. While production was initially scheduled to end in January 2020 a report from our sister publication, Cadillac Society, indicated that CT6 production had been extended to mid-February, essentially giving the luxury four-door an extra two weeks on the line. The Chevrolet Impala, Chevy Volt, and Buick LaCrosse were all discontinued at the same time as the CT6.

Once CT6 production concluded, the Detroit-Hamtramck plant began its transition into GM’s Factory Zero plant, which officially opened in November 2021.

2024 Cadillac CT6

Second Generation (2024 – Present)

The Chinese market received an all-new second generation Cadillac CT6, which debuted in May 2023 and went on sale in Q2 2023. This model represents a complete overhaul over the first-generation model, and is sold exclusively in China. At this time, there are no plans to offer the second-generation CT6 in global markets outside of China.

The next-generation 2024 Cadillac CT6 is offered in four trim levels, including Base, Luxury, Premium Luxury and Platinum, while  the Sport trim is expected to launch later in the luxury sedan’s lifecycle.

For the time being, the CT6 is offered exclusively with rear-wheel-drive with fifty-fifty weight distribution, and harnesses the luxury marque’s turbocharged 2.0L I4 engine (production code LSY), which is rated at 233 horsepower and 258 pound-feet of torque mated to the 10-speed automatic transmission and riding on the MRC 4.0 suspension. More drivetrain configurations could be introduced in the future.
