The 2025 Cadillac CT4 with the 2.0L turbo four-cylinder achieves 26 MPG combined. It’s not designed to compete with hybrids in fuel efficiency. Instead, the CT4 provides a good mix of energetic performance and reasonable fuel consumption for drivers who value driving enjoyment and some luxury above extreme fuel savings. These buyers appreciate the CT4’s responsive handling and stylish design and are willing to accept average fuel economy for that experience.

City and highway performance

EPA estimates show 22 MPG in the city and 32 MPG on the highway, showing the CT4 2.0L’s versatility. Stop-and-go traffic in cities reduces fuel economy because of frequent acceleration and braking. The eight-speed automatic transmission, while smooth and responsive, doesn’t completely solve the engine’s fuel consumption in these conditions. The CT4 performs much better on highways. At consistent speeds, the engine cruises comfortably, and the transmission selects higher gears, allowing the car to reach the advertised 32 MPG. Drivers who commute mainly on highways will benefit the most from the CT4’s fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Cadillac CT4 2.0L at $2,250. This is calculated based on driving 15,000 miles per year, with 55% of those miles in the city and 45% on the highway. The calculation assumes gasoline prices match the national average. Keep in mind that your fuel costs may change based on your driving habits, the fuel you use, and changes in gas prices. Expect to pay more if you mostly drive in the city or accelerate quickly. On the other hand, you might spend less than $2,250 if you primarily drive on the highway and drive efficiently.

Real-world expectations

EPA estimates are a helpful guide, but real-world fuel economy can vary. Drivers should see results close to the EPA numbers, but results can change. Hard acceleration, frequent short trips, and heavy cargo will all decrease fuel efficiency. Gentle driving, regular maintenance, and correct tire pressure can help you match or improve upon the EPA estimates. The CT4’s information display provides real-time fuel economy data, so drivers can track their fuel consumption and adjust their driving. Explore CT4 MPG across all years to see if previous years’ numbers match your expectations before you buy.

How it compares

Compared to competitors, the 2025 Cadillac CT4 with the 2.0L engine is about average. The BMW 330i, for example, has an EPA-estimated 28 MPG combined, offering slightly better fuel economy. The Mercedes-Benz C300 is rated at 25 MPG combined, making it a little less efficient than the CT4. The Acura Integra, especially in A-Spec trim, achieves around 30 MPG combined. The Audi A4, with its standard quattro all-wheel-drive, is rated at 27 MPG combined. These differences can add up over time. CT4 buyers should consider these figures along with styling, features, and driving. This buyer likely considered all Cadillac fuel economy data alongside the competition before deciding.

Tips to maximize efficiency

Avoid hard acceleration and braking. The CT4’s turbocharged engine responds quickly, but frequent heavy acceleration will use up fuel quickly. Drive smoothly and gradually, anticipating traffic and keeping a steady speed.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tires regularly and inflate them to the pressure listed on the sticker inside the driver’s side door. This small step can make a big difference.

Reduce weight. Heavy items in your trunk or back seat increase the vehicle’s weight, making the engine work harder and using more fuel. Remove unnecessary items from your car to improve efficiency.

Use cruise control on the highway. Cruise control helps maintain a constant speed, avoiding unnecessary acceleration and deceleration. This can greatly improve fuel economy on long highway drives, allowing the CT4’s engine to run at its best.

Consider using the CT4’s drive modes. While “Sport” mode improves performance, “Tour” or “Eco” mode focuses on fuel efficiency by changing engine and transmission settings. Experiment with these modes to see which works best for your driving and fuel-saving goals.
