27 MPG combined isn’t going to win any hypermiling contests, but for the 2021 Mercedes-Benz CLA250 4matic, it’s a reasonable trade-off for the style, technology, and performance that define this four-door coupe. The CLA250 4matic is for a buyer who prioritizes design flair and a premium ownership experience, acknowledging that fuel efficiency is less important than other considerations. These owners are often young professionals or empty-nesters drawn to the Mercedes-Benz brand and the CLA’s distinctive shape. They’re willing to spend a little more at the pump for the prestige and driving experience that the CLA250 offers.

City and highway performance

The EPA estimates a fuel economy of 24 MPG in the city and 33 MPG on the highway for the 2021 Mercedes-Benz CLA250 4matic. The city figure reflects the demands placed on the 2.0L turbocharged four-cylinder engine in stop-and-go traffic, while the highway number demonstrates its efficiency during sustained cruising. This split is typical for vehicles with internal combustion engines, with the highway MPG benefiting from lower engine loads and consistent speeds. Drivers who spend most of their time navigating urban environments should expect fuel consumption closer to the 24 MPG mark, while those with longer highway commutes will likely see numbers approaching or even exceeding 33 MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz CLA250 4matic at $2,150 per year. This figure is based on driving 15,000 miles annually, using national average fuel prices for premium gasoline, which is recommended for optimal performance in the CLA250’s engine. Keep in mind that local fuel prices can vary significantly, so your actual fuel costs may be higher or lower depending on your region and driving habits. Also, premium fuel typically costs more than regular unleaded, so using the recommended fuel will increase your annual fuel cost.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy can change based on driving style, traffic conditions, and vehicle maintenance. Aggressive acceleration, frequent hard braking, and extended idling will reduce fuel efficiency. Regular maintenance, including tire inflation and timely oil changes, also helps maximize MPG. Drivers who adopt a smooth, consistent driving style are more likely to achieve or even surpass the EPA’s estimates. You can also check CLA250 MPG across all years to see how prior years compare.

How it compares

In the world of compact luxury cars, the 2021 Mercedes-Benz CLA250 4matic’s fuel economy is competitive, but not class-leading. For instance, the BMW 228i xDrive Gran Coupe, another stylish four-door coupe, achieves a slightly better combined MPG of 28. The Audi A3 Sedan, especially in its front-wheel-drive configuration, can often see numbers in the low 30s for combined MPG. Even the Acura ILX, while not positioned as directly as a competitor, offers combined MPG around 28. The choice between these vehicles often comes down to brand preference, features, and styling, with fuel economy being one factor among many. These differences, while seemingly small, add up to real dollars annually. If fuel economy is your sole focus, consider the BMW or Audi.

Tips to maximize efficiency

Adopt a smooth and anticipatory driving style. Avoid sudden acceleration and hard braking, as these actions consume more fuel. Maintaining a consistent speed and anticipating traffic flow can significantly improve your MPG. Use cruise control on long highway stretches to keep MPG consistent.

Ensure that your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check tire pressure regularly, especially during temperature changes, as pressure can change.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart efficiently, and the fuel saved by avoiding prolonged idling can add up over time. Don’t warm up the car for extended periods, especially in mild weather.

Keep your vehicle properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance ensure that your engine is running efficiently. A poorly maintained engine consumes more fuel and produces more emissions. You can find all Mercedes Benz fuel economy data on this site.

Reduce unnecessary weight in your vehicle. Excess weight increases fuel consumption. Remove any items from the trunk or backseat that you don’t need on a regular basis. A lighter car consumes less fuel.
