The 2025 Cadillac CT4 and 2025 Cadillac CT5 both offer luxury, performance, and advanced technology, but they cater to different drivers. The CT4 is a subcompact four-door with agile handling, while the CT5 is a midsize sedan that provides a more spacious, refined ride. Let’s compare the two so you can make the best decision for your needs when buying your new Cadillac.
KEY TAKEAWAYS
- The CT4 is the smallest model in Cadillac’s sedan lineup.
- The CT4 features standard rear-wheel drive across trims—a rarity in most sedans.
- The 2025 Cadillac CT4 starts at $36,390 and goes up to $48,690 over its four trims; the 2025 Cadillac CT5 is priced from $48,990 to $58,390. Prices are effective April 2, 2025.
2025 Cadillac CT4 vs. CT5: Which Luxury Sedan Has the Best Engine and Powertrain?
The Cadillac CT4 is small but has a little pep in its step, nonetheless. It offers two powertrains:
- A 2.0-liter four cylinder generating 237-horses (standard in the base Luxury, Premium Luxury and Sport models);
- A standard 2.7-liter four in the CT4-V delivers 325 horsepower and is available for the Premium Luxury trim, making 310 horsepower.
The 2.0-liter engine mates with an eight-speed automatic transmission, while the 2.7-liter engine is paired with a 10-speed automatic transmission. Rear-wheel drive is standard across trims with all-wheel drive as an option.
The CT5 features the same 237-hp turbocharged 2.0-liter four-cylinder, but the powertrain similarities end there. A 335-hp twin-turbocharged 3.0-liter V-6 is optional. The high-performance CT5-V features a 360-hp version of the twin-turbo V-6, adaptive dampers, and an electronically controlled limited-slip differential.
No matter your powertrain choice, engines mate solely with a 10-speed automatic transmission, and again, rear-wheel drive is standard across trims with optional all-wheel drive.
Which Sedan Offers Better Fuel Economy—the 2025 Cadillac CT4 or 2025 Cadillac CT5?
In terms of fuel economy, the CT4’s 2.0-liter engine gets 23 mpg city/34 mpg highway, while the 2.7-liter four gets a little less, at 21 mpg/city, 31 mpg/highway. In the CT5, the numbers are close—its standard turbo-four gets 23 mpg/city and 33 mpg/highway. The 335-hp V-6 gets 19 mpg/city and 27/highway, and in the 360-hp version those numbers drop to 18 mpg/city and up to 27/mpg highway.
Interior Features of the 2025 Cadillac CT4 vs. 2025 CT5 Compared
The CT4’s overall cabin space can feel a bit tight (remember, it’s the smallest of the Cadillac sedans) as can cargo space, which has just 10.7 cubic feet of breathing room in the trunk. The base trim is fairly practical and no frills, but comfortable just the same, while optional luxury and tech amenities offered in higher trims will push all user-friendliness and style buttons. The CT5, while stylish with more luxurious features, isn't ideal for taller adults, particularly in its back row—and its low stance and sloping roofline at the back make it challenging to enter and exit.
All CT4 trims feature an 8.0-inch infotainment touchscreen system with Cadillac’s CUE software, Apple CarPlay, Android Auto and onboard Wi-Fi hotspot as standard. Navigation is available for all trims, as is a 14-speaker Bose stereo system.
The CT5 takes things up more than a notch here, with a massive 33-inch user-friendly digital display and many of the same software features listed above. Its touchscreen can be operated by dial control, giving you the choice of how you want to interact with the system.
