25 MPG combined might not sound like the best gas mileage, but the 2024 Cadillac CT5 AWD 2.0L 4-cyl is designed to be a comfortable, stylish and capable luxury sedan providing confidence in all weather. It’s not a hybrid aiming for ultimate efficiency. This car is for executives and drivers who want a premium experience without completely giving up fuel economy. The CT5 buyer wants a Cadillac, appreciates the brand’s heritage, and accepts the fuel consumption.

City and highway performance

The EPA estimates the 2024 CT5 AWD 2.0L achieves 22 MPG in the city and 30 MPG on the highway. These figures represent typical urban driving and consistent highway speeds. The 2.0L turbocharged four-cylinder, paired with a 10-speed automatic transmission, balances power and reasonable fuel consumption. The highway number is more impressive, showing the engine’s efficiency at stable speeds, which is ideal for long commutes or road trips. Remember that driving style and conditions play a big role, and aggressive acceleration or heavy traffic will hurt these numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Cadillac CT5 AWD 2.0L is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. This is just an estimate, and your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and changes in fuel prices, but this figure provides a benchmark for budgeting fuel expenses for the year. Compare this to the annual fuel cost for this vehicle with the CT5 MPG across all years to understand changes over time.

Real-world expectations

The EPA ratings provide a standardized benchmark, but real-world fuel economy often differs. Expect to see numbers slightly below the EPA estimates in mixed driving conditions, especially if you often encounter heavy traffic or drive aggressively. Many owners report about 28 MPG on long highway trips when following posted speed limits. Consistent, smooth acceleration and careful driving can help close the gap between the EPA figures and what you see.

How it compares

The CT5 is in a competitive market segment, and its fuel economy reflects that. The BMW 330i xDrive, another popular choice with all-wheel drive, reports 28 MPG combined. The Mercedes-Benz C300 4MATIC achieves a similar 26 MPG combined. The Acura TLX with its standard 2.0L turbo and SH-AWD system gets 24 MPG combined, slightly below the CT5. These differences can add up over time. But, the decision to purchase a CT5 often depends on things other than fuel economy, such as styling, brand preference, and features. Drivers interested in saving more at the pump can review all Cadillac fuel economy data, including hybrid models.

Tips to maximize efficiency

Use the CT5’s drive mode selector. The “Tour” or “Eco” mode will optimize the engine and transmission settings for fuel efficiency, prioritizing lower RPMs and softer acceleration. Selecting this mode during consistent driving can noticeably improve your MPG.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels specified on the tire placard, typically located on the driver’s side doorjamb.

Avoid unnecessary idling. Modern engine technology allows for quick restarts, and idling consumes fuel without any forward progress. If you expect to be stopped for more than a minute, consider turning off the engine. Do not idle to warm up the engine. It is more fuel-efficient to drive gently.

Remove any unnecessary items from the trunk or rear seats as extra weight increases the engine’s workload, resulting in decreased fuel economy. Clean out your car regularly to minimize the amount of cargo you’re carrying around.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel efficiency on long, relatively flat stretches of road. But, avoid using cruise control in hilly terrain, as the system may aggressively downshift to maintain speed, negating any potential fuel savings.
