27 MPG combined shouldn’t be the primary decision-making factor for buyers of the 2018 Mercedes-Benz CLA250 4matic. This sleek, entry-level luxury sedan prioritizes style and badge appeal over outright efficiency. It’s not a gas guzzler, but it’s not a Prius either. The CLA250 4matic is aimed at younger buyers or those new to the Mercedes-Benz brand, individuals often more interested in making a statement than hyper-miling. For them, fuel economy is likely an acceptable compromise for the cachet of the three-pointed star and the engaging driving experience (especially in 4matic guise).

City and highway performance

The EPA estimates fuel economy at 24 MPG in the city and 32 MPG on the highway. These numbers reflect the realities of the CLA250’s turbocharged 2.0L four-cylinder engine and its seven-speed automatic transmission (AM7). The city figure acknowledges the stop-and-go driving that the engine frequently encounters, impacting fuel consumption. The highway MPG suggests that the engine is reasonably efficient at cruising speeds, especially when the transmission shifts into its higher gears. Drivers should understand that aggressive acceleration and frequent use of the Sport mode will likely reduce these numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mercedes-Benz CLA250 4matic to be $2,150. This calculation is based on driving 15,000 miles per year, using national average fuel prices, and assumes a mix of city and highway driving conditions. Your actual fuel costs may vary significantly depending on your driving habits, the type of fuel you use (premium is recommended), and where you live, as fuel prices can vary widely by region. Drivers who commute longer distances or have heavier feet will find this figure optimistic.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy for the CLA250 4matic can vary. Some owners report figures closer to the low 20s in the city and high 20s on the highway, especially in areas with hilly terrain or frequent traffic congestion. The car’s all-wheel drive system (4matic), while enhancing grip and stability, also adds weight and can slightly reduce fuel efficiency compared to the front-wheel-drive version. Consistent use of the Eco driving mode, and a conscious effort to drive smoothly, are crucial for achieving numbers closer to the EPA estimates. Don’t expect hybrid-like fuel economy; focus on driving habits instead.

How it compares

The 2018 Mercedes-Benz CLA250 4matic’s fuel economy stacks up reasonably well against its direct competitors, but some alternatives offer better numbers. For instance, a 2018 Audi A3 quattro, with its turbocharged 2.0L engine, achieves roughly similar fuel economy, around 25 MPG combined. A BMW 230i xDrive coupe, another sporty contender, might offer slightly better highway numbers, approaching 34 MPG, thanks to BMW’s focus on efficient engine technology. The Lexus IS 300 AWD, with its larger V6 engine, typically lags behind, hovering around 23 MPG combined. The comparison is important to a CLA buyer because while style and brand are important, no one wants to feel like they’re sacrificing fuel economy for the sake of aesthetics. Drivers who are looking for even greater fuel efficiency from the Mercedes-Benz brand might explore all Mercedes Benz fuel economy data to consider a model. Comparing the CLA250 MPG across all years could also show incremental gains in economy.

Tips to maximize efficiency

Engage the Eco driving mode whenever possible. The CLA250’s Eco mode optimizes engine and transmission settings for fuel efficiency, often resulting in better MPG during city driving. The system dampens throttle response and initiates earlier upshifts, promoting a more relaxed and fuel-conscious driving style.

Monitor tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure at least once a month, or before any long trips, and inflate them to the recommended pressure listed on the doorjamb sticker.

Minimize unnecessary weight. Carrying extra cargo in the trunk or backseat adds weight to the vehicle, reducing fuel economy. Remove any items you don’t need, such as sports equipment or tools, to lighten the load and improve efficiency, especially on longer drives.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and high-speed cruising consume significantly more fuel. Drive smoothly and anticipate traffic conditions to maintain a consistent speed and minimize the need for abrupt maneuvers. This is especially relevant to the CLA250, as its turbo engine can easily consume more fuel when driven aggressively.

Consider using cruise control on the highway. Cruise control helps maintain a constant speed, reducing fuel consumption compared to constantly varying your speed manually. This is particularly effective on relatively flat stretches of highway with minimal traffic congestion.
