The 2023 Cadillac CT4 arrives with just a handful of changes and updates over the 2022 model, including the addition of the Driver Assist Package as standard, the addition of the CT4 Bronze Accent Package as well as the CT4 Blue Accent Package. However, the 2023 CT4 has lost the Diamond Sky Special Edition Package.
The Cadillac CT4 rides on the GM Alpha 2 platform and is offered with the turbocharged 2.0L I4 LSY gasoline engine, rated at 237 horsepower and 258 pound-feet of torque, on all three trim levels. The turbocharged 2.7L I4 L3B, rated at 310 horsepower and 350 pound-feet of torque, is available as an option on the Premium Luxury. The LSY engine connects to the GM eight-speed automatic transmission, while the L3B engine connects to the GM 10-speed automatic transmission. All these trims are available in both rear-wheel drive and optional all-wheel drive configurations.
Finally, unique badging for the super sedans.
