Overview
The first-generation CT6 is built on a different platform than the smaller CTS and is engineered as a rear-wheel drive vehicle with optional all-wheel drive. In addition to its primary markets of North America and China, the CT6 was also offered in Europe, South Korea, Japan, and the Middle East. General Motors discontinued the assembly of the Cadillac CT6 in the US in February 2020 due to poor sales and retooling of the Detroit/Hamtramck facility for electric vehicle production, beginning with the new GMC Hummer EV.
Powertrain
The 4.2-liter twin-turbo 'Blackwing' V8 engine was made available for the 2019 and 2020 models making 550 hp for the CT6-V model and 500 hp for other models with the Platinum trim. Torque for both engines is 640 and 574 lbft respectively. This is the most sophisticated V8 engine ever made by General Motors. It reportedly cost GM about $20,000 each to produce this engine. Production of the 4.2TT Blackwing models were limited with CT6-V totals of 504 (2019) and 411 (2020) while the Platinum totals were 168 (2019) and 117 (2020).
Technology
The CT6 line comes with one of three audio systems designed by Bose Corporation: an 8-speaker Bose Premium Sound System, a 10-speaker Bose Centerpoint Surround-Sound System, or the top-of-the-line 34-speaker Bose Panaray Surround-Sound System, which processes stereo audio into Surround Sound using Bose's automotive sound system technologies, as well as technologies from its Panaray line of professional speakers; typical Dolby or DTS surround modes are not available.
