The 2017 Mercedes-Benz CLA250 4matic, with its 27 MPG combined EPA rating, is not trying to be a Prius. Instead, it aims to deliver a credible balance of fuel efficiency and sporty performance for buyers drawn to the Mercedes-Benz badge in a compact, coupe-like sedan. It’s a gateway to the brand, appealing to younger, style-conscious buyers who want some luxury without totally emptying their wallets. These owners prioritize aesthetics and the prestige of the logo, and they accept the CLA250’s economy as a decent compromise.

City and highway performance

The EPA estimates detail 23 MPG in the city and 32 MPG on the highway. The city figure reflects the stop-start nature of urban driving, a setting where the CLA250’s 2.0L turbocharged 4-cylinder engine can feel a bit strained hauling around its approximately 3,400-pound curb weight. Highway driving, however, is where the car performs best. The smooth-shifting automatic transmission (AM7) allows for relaxed cruising at higher speeds, helping to achieve the more favorable 32 MPG number. Expect some drop off when the car is loaded with passengers or luggage, or during high-speed runs.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2017 Mercedes-Benz CLA250 4matic at $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that fuel prices fluctuate considerably, and individual driving habits, including how often you accelerate aggressively or drive in stop-and-go traffic, directly impact your real-world costs. Also, depending on which state you live in, premium fuel is recommended for optimal performance, which can raise the price even higher.

Real-world expectations

While the EPA’s 27 MPG combined rating is a useful benchmark, expect some variance in everyday driving. Owners who spend most of their time in congested city environments will likely see numbers closer to the 23 MPG city estimate, perhaps even a bit lower depending on driving style. Conversely, those who primarily drive on the highway might see figures exceeding the 32 MPG highway rating, particularly with mindful driving habits. A combined trip of 50 miles of highway and 20 miles of city driving should yield around 30 MPG.

How it compares

In the compact luxury sedan segment, the CLA250’s fuel economy is about average. The 2017 Audi A3 2.0T Quattro, for instance, delivers a similar 27 MPG combined, while the BMW 228i xDrive manages around 26 MPG combined. The Acura ILX, with its less powerful engine, sometimes achieves slightly better numbers, hovering around 28 MPG combined in some model years. The CLA buyer isn’t necessarily seeking the absolute best MPG; they’re making a trade-off. They weigh the value the 2.0L turbo engine together with the CLA250’s design and brand image, sometimes accepting slightly lower MPG to get it.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking, as these habits dramatically decrease fuel efficiency. The CLA250’s turbocharger is responsive, but it’s also sensitive to how far you press the gas pedal. Gentle acceleration and anticipating traffic flow will allow you to maintain momentum and significantly improve your MPG.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure regularly, using the values listed on the doorjamb, and maintain the recommended pressure for best efficiency.

Minimize idling time. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed for efficient restarting, and extended idling wastes fuel without providing any benefit. This is especially important in stop-and-go urban environments.

Reduce unnecessary weight. Remove any unnecessary items from the trunk or backseat. Every extra pound adds to the car’s overall weight, diminishing fuel economy. This is a small adjustment, but it can make a noticeable difference over time. See all Mercedes Benz fuel economy data.

Use cruise control on the highway when appropriate. Maintaining a consistent speed helps to optimize fuel consumption. Cruise control minimizes variations in throttle input, leading to smoother and more efficient driving over longer distances.
