2026 Cadillac CT4: What's New, Specs & Features
Last updated August 4, 2026
The 2026 Cadillac CT4 gets a light equipment update rather than a redesign. The headline change is that heated front seats and a heated steering wheel are standard on every trim.
About the 2026 Cadillac CT4
1st gen (2020-2026), final year
Cadillac positions the CT4 as a small luxury sedan for drivers who still care about how a car feels from behind the wheel. The brand leans on rear-wheel-drive proportions, athletic balance, bold styling, useful cabin tech, and a strong list of standard safety features. Compared with many front-drive rivals, the CT4’s identity is more traditional sport sedan: compact, driver-focused, and sharper to drive while still serving as an everyday premium commuter.
The Luxury trim covers the essentials with a turbo engine, an 8-inch touchscreen, wireless phone charging, and a solid set of safety features. Premium Luxury adds leather, seat memory, and extra driver assistance, while Sport brings more aggressive body details, heavily bolstered sport seats, paddle shifters, and alloy pedals. This is the final model year for the current CT4.
