When it comes to these two great vehicles, the core of the CT4 does not change for 2026. It continues on the same platform with the same turbocharged engine options that define its performance-focused driving character. Where the difference shows up is in the details. For 2026, Cadillac shifts several comfort and convenience features to standard equipment and adjusts exterior color availability.
Key Takeaways:
- The 2026 Cadillac CT4 features more standard comfort features compared with the 2025 model.
- Heated seats and a heated steering wheel are now standard on all trims for 2026.
- The Climate Package and Cold Weather Package that were optional on the 2025 models are now standard on respective trims for 2026.
Are there any engine or mechanical changes for the 2026 Cadillac CT4 compared with the 2025 model?
No, the 2026 Cadillac CT4 and 2025 Cadillac CT4 continue with the same powertrain options.
Both model years are powered by Cadillac's turbocharged four-cylinder engines, including:
- A 2.2.0 liter turbocharged I4 (LSY) producing approximately 237 horsepower and 258 pound-feet of torque.
- An available 22.7 liter turbocharged I4 (L3B) is available on higher trims, producing around 310 horsepower and 350 pound-feet of torque.
This means daily acceleration, highway merging, and general performance characteristics remain consistent between 2025 and 2026 sedans. Drivers will find familiar throttle response and transmission behavior year-over-year since the engines and eight-speed automatic transmission are carried over.
