24 MPG combined won’t set any fuel efficiency records, but that’s what you get with the 2023 Mercedes-Benz AMG CLA35 4matic. This car isn’t about saving gas. It’s a statement. A compact, aggressively styled four-door coupe with real AMG DNA. Buyers want performance and style first, accepting fuel economy as a secondary, but still important, consideration.

City and highway performance

The EPA estimates the CLA35 gets 21 MPG in the city and 29 MPG on the highway. The city number reflects the stop-and-go of urban driving, where the 2.0L turbocharged four-cylinder works constantly. The AMG-tuned automatic transmission tends to hold gears longer, keeping the engine higher in the rev range, even in Comfort mode. The highway number is better, showing the engine’s ability to cruise efficiently at higher speeds. Expect that 29 MPG number to drop if you give in to the temptation to test the CLA35’s performance on open roads.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2023 Mercedes-Benz AMG CLA35 at $2,400. This calculation is based on driving 15,000 miles per year, with a set percentage split between city and highway driving, using the national average fuel price when calculated. Actual costs will vary depending on driving habits, local fuel prices, and fuel type. The CLA35 needs premium gasoline to deliver its rated performance and efficiency. Consider this $2,400 estimate a baseline, knowing enthusiastic driving will increase that number.

Real-world expectations

The EPA provides a standard, but real-world fuel economy often differs. Some AMG CLA35 owners report figures slightly below the official estimates, especially in mixed driving. Aggressive acceleration, frequent use of Sport or Sport+ driving modes, and extended idling can lower MPG. However, drivers who want better fuel efficiency and drive more conservatively might see numbers closer to, or even slightly above, the EPA estimates. The car’s computer provides real-time and average fuel consumption data, letting drivers monitor their efficiency and adjust their driving.

How it compares

The AMG CLA35’s fuel economy is competitive with rivals, though some are slightly more efficient. The BMW M235i xDrive Gran Coupe, another performance four-door coupe, gets a combined 26 MPG. The Audi S3, with a similar powertrain, posts 27 MPG combined. These differences probably won’t sway buyers in this segment. People examining these vehicles probably care more about performance, styling, and brand than small fuel savings. Even the less powerful Mercedes-Benz CLA250 only manages 28 MPG combined, showing the MPG penalty for the AMG treatment. You can also view all Mercedes Benz fuel economy data on this site.

Tips to maximize efficiency

Carefully use the car’s driving modes. Sport and Sport+ modes give enhanced performance, but they also consume more fuel. Use Comfort mode during steady cruising and highway driving to maximize efficiency. Dynamic modes are fun but costly.

Check tire pressure regularly. Underinflated tires increase rolling resistance, and that reduces fuel economy. The CLA35’s tire pressure monitoring system tracks tire pressure and helps you maintain optimal inflation.

Avoid aggressive acceleration and braking. Smooth inputs minimize fuel consumption. Anticipate traffic flow and maintain a consistent speed. Turbo engines like this one are very sensitive to throttle inputs, and driving at a more relaxed pace will improve MPG and make your drive less stressful and easier.

Reduce weight by removing unnecessary cargo from the vehicle to improve its power-to-weight ratio and reduce fuel consumption. Every pound counts. Think about how much unnecessary weight you carry in the car and its impact on MPG and fuel expenses.

The CLA35 4Matic is a performance variant. While you can improve fuel economy with good habits, don’t expect amazing numbers since you are buying it for performance and handling. For more Mercedes-Benz AMG information, look at AMG MPG across all years.
