The base engine is a refined 3.6-liter V6. All-wheel drive is standard. The interior is plush and roomy, but in-cabin storage is practically nonexistent. Front-seat comfort is superb, but the rear seat is short on thigh support. The CT6's Super Cruise driver assistance system operates on freeways and monitors the driver to make sure he or she is paying attention. The V and Platinum models get a powerful turbo V8. For the 2020 model year, all CT6 trim lines come standard with forward collision warning, city-speed automatic emergency braking with pedestrian detection, blind spot warning, and rear cross traffic warning.
