The 2024 Cadillac CT4 with the 2.0L turbocharged four-cylinder engine achieves 26 MPG combined. While this doesn’t make it the most fuel-efficient in the compact luxury sedan class, it’s a reasonable choice for buyers who want a mix of style, sporty handling, and a well-appointed interior. This car appeals to those who enjoy driving and appreciate Cadillac’s style, even if it means slightly higher fuel costs.

City and highway performance

The EPA estimates the 2024 CT4 2.0L gets 22 MPG in the city and 32 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the engine works harder and fuel consumption increases. On the highway, the engine’s efficiency shines at a consistent cruising speed. The eight-speed automatic transmission helps get better fuel economy in both situations, keeping the engine in its best range. Drivers with longer commutes or frequent highway trips will likely see fuel economy closer to 32 MPG, while drivers in cities should expect numbers closer to 22 MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Cadillac CT4 2.0L at $2,250. This is based on driving 15,000 miles per year and using national average fuel prices. It’s a standard way to compare the running costs of different vehicles. Remember that your actual fuel costs may change based on your driving habits, local fuel prices, and the fuel you use. Using premium fuel, while not required, might slightly improve performance but will increase the cost per gallon. View all Cadillac fuel economy data here.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy can vary based on how you drive and the conditions. Driving fast, braking hard, and skipping regular maintenance can all hurt fuel efficiency. On the other hand, driving smoothly, keeping your tires properly inflated, and following the recommended service schedule can help you reach or even beat the EPA estimates. Tracking your own mileage is the best way to understand what to expect in your daily driving.

How it compares

The CT4’s fuel economy is competitive in the compact luxury sedan segment, but not the best. The BMW 330i, for example, gets a slightly better 28 MPG combined, which is good for buyers who want performance and luxury with better fuel efficiency. The Mercedes-Benz C300 also achieves 28 MPG combined. The Acura Integra has an available hybrid powertrain and prioritizes fuel economy, achieving up to 51 MPG in the city in hybrid trims, but it’s for buyers primarily seeking efficiency. The Audi A4 40 TFSI delivers 29 MPG combined. Buyers who choose the CT4 often like its Cadillac styling, available Super Cruise technology, and a more engaging driving experience than some rivals focused on economy, so they accept the difference.

Tips to maximize efficiency

The 2.0L turbo in the CT4 responds well to smooth acceleration. Avoid speeding and try to predict traffic to reduce braking. A gentle touch on the gas pedal will improve fuel economy.

Keeping your tires inflated is important for safety, handling, and fuel efficiency. Check your tire pressure regularly and inflate them to the recommended PSI listed on the doorjamb. Tires with low pressure create more rolling resistance, which reduces fuel economy.

Take out extra weight in the car. Extra cargo adds to the load and makes the engine work harder, burning more fuel. Remove anything from the trunk that isn’t needed for daily driving.

Consider cruise control on long highway drives. Keeping a steady speed helps with fuel economy compared to changing your speed constantly. Watch road conditions and traffic, and turn off cruise control when needed for safety.

Regular maintenance, including oil changes, air filter replacements, and spark plug maintenance, helps the engine run well. A well-maintained engine uses less gas and produces fewer emissions. Follow the service schedule in your owner’s manual.
