25 MPG combined won’t top any lists, but it’s a perfectly reasonable figure for the 2021 Mercedes-Benz AMG A35 4MATIC. This isn’t a hybrid commuter car; it’s a performance-focused hot hatchback engineered to deliver thrills first. The A35 is for drivers who want a stylish, compact, and aggressively fun driving experience, and they’re usually willing to accept slightly lower fuel economy to get it.

City and highway performance

The EPA estimates the A35 4MATIC achieves 22 MPG in the city and 29 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the turbocharged 2.0L engine is more likely to be operating off-boost. The highway number, however, demonstrates good fuel economy at consistent speeds. These figures aren’t class-leading, but they’re acceptable given the A35’s performance and standard all-wheel-drive system.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Mercedes-Benz AMG A35 4MATIC at $2,300. This is based on driving 15,000 miles per year, using a national average fuel price that the EPA updates regularly. Remember that premium fuel is recommended for optimal performance, and higher grade gasoline will increase your actual annual fuel costs. Driving habits and local fuel prices can further impact your fuel expenses, so this figure is an estimate to help you compare running costs with other vehicles.

Real-world expectations

While the EPA provides standardized testing, real-world MPG often varies. Factors like driving style, traffic conditions, and even tire pressure can influence fuel consumption. Expect slightly lower numbers if you frequently engage the A35’s performance features, such as launch control or Sport+ driving mode. On the other hand, consistently smooth acceleration and anticipating traffic flow can help you approach the EPA estimates. Learn more about all Mercedes Benz fuel economy data on our site.

How it compares

The Audi S3, a direct competitor also offering a turbocharged 2.0L engine and all-wheel drive, achieves a nearly identical 26 MPG combined. The BMW M235i xDrive Gran Coupe, another performance-oriented small car, is rated a 26 MPG combined. These cars are all targeting the same buyer, driving enthusiasts who want something luxurious and fun, but also compact and refined. The A35 buyer is clearly not shopping for maximum efficiency, and thus the minor variations amongst competitors often take a backseat against other considerations like styling, brand cachet, or driving feel. You can also see AMG MPG across all years.

Tips to maximize efficiency

Smooth acceleration is key. The AMG A35’s turbocharger delivers a significant performance boost when you demand it, but it also consumes more fuel. Gently apply the throttle and avoid aggressive acceleration to keep the engine operating within its most efficient range.

Use the car’s driving modes carefully. Comfort mode prioritizes fuel efficiency by optimizing throttle response and shift points. While Sport and Sport+ modes enhance responsiveness, they also increase fuel consumption. Save these modes for spirited driving on appropriate roads.

Maintain proper tire inflation. Low tire pressure increases rolling resistance, making the engine work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended levels listed on the driver’s side doorjamb.

Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, turn off the engine.

Reduce aerodynamic drag. Remove unnecessary items from the roof rack or cargo carrier, as they increase wind resistance and negatively impact fuel efficiency, especially at highway speeds. Even a seemingly minor change can have a noticeable effect over long distances.
