How are the 2026 Cadillac CT4 Luxury and Premium Luxury different?
Both compact luxury sedans are big on power and plush comfort. As the entry-level CT4 trim model, the Premium gives you a great deal on high-end cruising. The Premium Luxury represents the next level up, adding upscale features you might not want to miss. As the middling CT4 option, the Premium Luxury also helps keep costs down. And while both sedans deliver smooth comfort and turbocharged power, only the Premium Luxury is available with a bigger, faster powertrain!
Which 2026 Cadillac CT4 trim fits my daily driving style better, the Luxury or Premium Luxury?
While the base CT4 Luxury is sharp and quick, the mid-level CT4 Premium Luxury offers next-level powertrain upgrades. Of the pair, only the Premium Luxury is available with the extra-quick, 310-horsepower engine upgrade. It's also the only one of these trim models available with Super Cruise hands-free driving technology!
On the other hand, both sedans are available with all-wheel drive to help you navigate tight turns and slippery highways. And the base engine -- a twin-scroll turbocharged inline-4 -- is nothing to sneeze at, either. Its 237 horses will have you blending seamlessly into fast-moving Sacramento traffic!
