The 2022 Mercedes-Benz AMG CLA35 4matic gets 24 MPG combined, which isn’t the best fuel economy, but this car is a performance machine disguised as a stylish compact coupe. This isn’t a car designed for hypermiling; it’s built for quick acceleration, sharp handling, and a driving experience that prioritizes fun over frugality. The expected buyer of the AMG CLA35 knows this. They’re not looking for ultimate economy; they want a taste of AMG performance in a relatively compact and affordable package.

City and highway performance

The AMG CLA35’s EPA ratings break down to 21 MPG in the city and 29 MPG on the highway. The lower city MPG reflects the realities of stop-and-go traffic and the temptation to exploit the car’s responsive engine. The highway figure is more respectable, suggesting that you can achieve reasonable fuel economy on longer trips if you resist the urge to constantly overtake and can maintain a relaxed cruising speed. These figures are achieved using the car’s automatic (AM7) transmission that helps to strike a balance between performance and efficiency.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2022 Mercedes-Benz AMG CLA35 4matic. This figure is based on driving 15,000 miles per year and using national average fuel prices. Of course, this number is just an estimate. You may spend more or less depending on your actual driving habits, the amount you drive, and local fuel prices. Aggressive driving, consistently exceeding the speed limit, and frequent short trips will all increase your yearly fuel expenditure above the EPA estimate.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often varies. Expect to see numbers slightly below the EPA estimates if you frequently engage the car’s sportier drive modes or consistently drive in heavy traffic. Conversely, if you prioritize smooth acceleration and maintain consistent speeds on the highway, you might achieve figures closer to, or even slightly above, the EPA’s 29 MPG rating. It’s important to remember that the AMG CLA35 is designed to be driven, and encouraged to be driven hard, therefore the driving behavior has a significant impact on fuel consumption. You can view AMG MPG across all years to see how this model stacks up against other performance models.

How it compares

Compared to other compact performance vehicles, the AMG CLA35’s fuel economy sits roughly in the middle of the pack. The Audi S3, with its 22 MPG combined rating, offers slightly worse efficiency. The BMW M235i xDrive Gran Coupe, on the other hand, is similar at around 26 MPG combined. These differences, while present, are not likely to be deal-breakers to the target buyer. These buyers are prepared to sacrifice a few MPG for the more distinctive styling and performance edge offered by their preferred marque, and can examine all Mercedes Benz fuel economy data. The buyer likely has more stringent requirements to be met outside of MPG when evaluating performance compact cars.

Tips to maximize efficiency

Use the AMG CLA35’s Eco or Comfort drive modes when possible. These modes optimize throttle response and shift patterns for efficiency, reducing fuel consumption without sacrificing day-to-day drivability. It remains a fun car in this mode whilst prioritizing minimizing the burn.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, negatively impacting fuel economy. This is a simple maintenance task that can subtly improve your MPG.

Avoid unnecessary idling, particularly in cold weather. Modern engines warm up quickly while driving, so prolonged idling is simply wasting fuel. Turn off the engine if you anticipate being stationary for more than a minute.

Practice smooth, progressive acceleration and braking. Avoid aggressive starts and hard stops, as these consume significantly more fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Remove any unnecessary weight from the vehicle. Extra cargo in the trunk or back seat adds to the car’s load and reduces fuel efficiency. Lightening the load can make a small but measurable difference over time.
