25 MPG combined is a reasonable fuel economy figure for the 2024 Cadillac CT4 AWD with the 2.0L 4-cylinder engine, though it’s unlikely to be a primary selling point for this particular configuration. Buyers choosing this CT4 are more likely prioritizing all-weather capability, a composed ride, and the cachet (or bargain pricing) of the Cadillac brand, accepting middling fuel economy as a trade-off for the overall package. They want a compact luxury sedan with a touch of sportiness and the confidence of all-wheel drive, and they’re willing to pay for it at the pump.

City and highway performance

The EPA estimates suggest you’ll see around 21 MPG in city driving and 31 MPG on the highway. These figures reflect the 2.0L turbocharged engine working with an 8-speed automatic transmission. The city MPG reflects the stop-and-go nature of urban environments, where the engine is constantly accelerating and decelerating, placing load on the turbocharger. The highway figure benefits from consistent speeds and less demand for rapid acceleration, allowing the engine to cruise efficiently. Drivers should temper expectations accordingly, especially if their commute involves significant stop-and-go traffic or aggressive driving habits, which can heavily penalize fuel economy.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,300 for the 2024 Cadillac CT4 AWD 2.0L. This calculation assumes 15,000 miles of driving per year and uses the national average fuel price at the time of testing, which the EPA always uses for comparison purposes. Individual fuel costs will vary depending on local gasoline prices and personal driving habits. Drivers who primarily drive in the city or have a lead foot can expect to exceed this figure, while those who do mostly highway driving and practice fuel-efficient driving techniques may see slightly lower costs.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Factors such as driving style, traffic conditions, terrain, and even tire pressure can influence the MPG you actually achieve. Expect slight variations based on these real-world variables. It’s not uncommon to see figures slightly above or below the EPA estimates, especially considering that the AWD system adds some drivetrain drag. Monitor your CT4’s trip computer and track fuel consumption over time to gain a better understanding of your specific fuel economy patterns. Refer to CT4 MPG across all years if you are considering trims from other model years.

How it compares

In the realm of compact luxury sedans with all-wheel drive, the CT4’s fuel economy is competitive but not class-leading. For example, the BMW 330i xDrive achieves a combined 28 MPG, offering a slight edge in efficiency with a similar driving experience. The Audi A4 quattro delivers around 27 MPG combined, splitting the difference between the CT4 and BMW. The Mercedes-Benz C300 4MATIC, with its combined rating of 26 MPG, is marginally more efficient. These comparisons are important for buyers weighing performance, luxury, and fuel efficiency against the price point of each model when considering all Cadillac fuel economy data.

Tips to maximize efficiency

Avoid aggressive acceleration. The 2.0L turbo engine is responsive, but rapid acceleration burns significantly more fuel. A smooth and gradual acceleration technique will minimize fuel consumption, especially from a standstill.

Maintain optimal tire pressure, as specified on the door placard. Under-inflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Regularly check and adjust tire pressure to the recommended level.

Minimize idling. Excessive idling, such as warming up the engine for extended periods in cold weather, wastes fuel. Modern engines warm up relatively quickly once you start driving, so it’s generally more efficient to begin driving gently as soon as possible.

Use cruise control on the highway when appropriate. Maintaining a consistent speed on long highway stretches can significantly improve fuel economy. Cruise control helps avoid unintentional speed fluctuations that can waste fuel, though it should not be used in wet or slippery conditions.

Consider using a lighter wheel and tire package when it’s time for replacement. A lighter wheel and tire setup reduces unsprung weight, which can improve fuel economy and handling. This is a small change that adds up over time and may improve the overall enjoyment of the CT4 experience.
