The 2024 Mercedes-Benz AMG CLA35 4matic 2.0L 4-cyl gets 25 MPG combined, which isn’t class-leading, but fuel economy isn’t the key focus. This is an AMG, after all, a performance car designed for driving thrills. The fuel economy results from the 302 horsepower and all-wheel drive, not the primary goal. Buyers want a stylish, fast, technologically advanced compact “coupe” with four doors and accept the fuel costs.

City and highway performance

The EPA estimates the AMG CLA35 gets 22 MPG in the city and 29 MPG on the highway. The city figure reflects the stop-and-go driving, while the highway number shows its efficiency at a steady speed. The 2.0L turbocharged engine, with an 8-speed automatic transmission (AM8), delivers power smoothly but uses fuel to maintain its quick response. Driving hard which the CLA35 encourages will lower real-world MPG compared to the EPA estimates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz AMG CLA35 is $2,300. This is based on driving 15,000 miles per year using national average fuel prices. This is important for buyers to consider when compared to less sporty cars. Premium fuel is required, increasing the cost per gallon and the annual expense. Driving more than 15,000 miles a year will increase that number, showing that performance driving has a price beyond the car’s MSRP.

Real-world expectations

EPA numbers are a benchmark, but actual fuel economy varies by driving habits, road conditions, and weather. Drivers who frequently engage the AMG’s performance features, like Sport+ mode and manual shifting, should see MPG below the EPA estimates. Those who accelerate smoothly and maintain consistent highway speeds might see slightly better results. Drivers can use the trip computer to see current MPG and adjust driving habits.

How it compares

The AMG CLA35’s fuel economy is normal for performance compact cars. The BMW M235i xDrive Gran Coupe a direct competitor, gets about 26 MPG combined. The Audi S3 another popular choice, achieves 27 MPG combined. Performance sedans like the Acura Integra Type S trade off some MPG, with an EPA rating of 24 MPG combined. The CLA35 gives the buyer the Mercedes-Benz badge and a luxury interior, so they must accept the average MPG. For all Mercedes Benz fuel economy data, browse here.

Tips to maximize efficiency

The AMG CLA35 prioritizes performance, but you can improve its fuel efficiency without losing the fun. Avoid hard acceleration and braking, as these consume more fuel. Smooth, consistent driving is key to better MPG.

Strategically use the car’s drive modes to save fuel. Comfort mode optimizes the engine and transmission for efficiency, while Sport and Sport+ modes prioritize performance. Selecting Comfort will soften the throttle and encourage earlier upshifts, reducing fuel use.

Make sure the tires are properly inflated. Underinflated tires increase rolling resistance, which lowers fuel economy. Check the tire pressure often and inflate them to the recommended levels for best efficiency.

Remove unnecessary weight from the car. Extra cargo in the trunk or back seat increases the energy to accelerate and maintain speed. Keeping the car clear can help improve fuel economy.

Consider using cruise control on long highway drives. Remaining at a consistent speed can optimize fuel efficiency by reducing unnecessary acceleration and deceleration, which can help you reach the 29 MPG highway rating.
