The 2021 Mercedes-Benz GLA250 4matic gets 27 MPG combined, which is an acceptable number for a subcompact luxury crossover with standard all-wheel drive. While it won’t break any fuel efficiency records, GLA buyers are usually more interested in the Mercedes-Benz brand, a size that fits well in cities, and the higher seating position of an SUV, all in a stylish design.

City and highway performance

The GLA250 4matic earns an EPA-estimated 24 MPG in the city and 33 MPG on the highway. This difference shows how the engine is tuned for both quick response and efficient cruising. In stop-and-go traffic, the 2.0-liter turbocharged four-cylinder provides plenty of low-end torque for quick acceleration. On the open road, the eight-speed automatic transmission (AM8) selects higher gears to lower engine speed and improve fuel economy. Drivers who do most of their driving in cities will probably see numbers closer to 24 MPG, while those with longer commutes can expect to get close to 33 MPG. The GLA’s small size makes it easier to drive on crowded streets, which is a big advantage over larger SUVs, and its light weight helps it be more efficient.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz GLA250 4matic at $2,150. This is based on driving 15,000 miles per year and using national average gas prices. Individual fuel costs will change based on driving habits, local gas prices, and the type of fuel used. The GLA250 doesn’t require premium fuel, but using it might slightly improve performance, but it will increase fuel costs. Drivers who want a small performance increase might choose to pay more for premium, but others will be fine with regular unleaded.

Real-world expectations

The EPA estimates provide a good starting point, but real-world fuel economy can be different. Factors like aggressive driving, heavy loads, and weather can all change the numbers you see. GLA250 drivers who focus on fuel efficiency can expect to get close to the EPA estimates, especially on longer trips. However, those who often use the Sport driving mode or drive mostly on short, city trips will likely get lower MPG. Larger optional wheels can also hurt fuel economy, as can incorrect tire pressures.

How it compares

The GLA250 4matic’s fuel economy compares well to its competitors. The BMW X1 xDrive28i, another popular subcompact luxury SUV, gets a combined 25 MPG. The Audi Q3 45 TFSI quattro gets 23 MPG combined. The Lexus UX 250h, a hybrid SUV, offers much better economy at 42 MPG combined, but it offers a very different driving experience and doesn’t have the GLA’s sporty feel. The GLA’s slightly better fuel consumption than the Audi and BMW may help buyers who want to save money on gas, but the trade-offs in other areas (price, features) will affect the final choice. Buyers who want the best fuel savings should consider the Lexus UX hybrid, but the GLA is a better choice for those who prefer performance and luxury.

Tips to maximize efficiency

Use the GLA250’s Eco driving mode. This setting changes the engine and transmission settings to focus on fuel efficiency instead of performance. The throttle responds less quickly, and the transmission shifts sooner, which improves MPG. It may feel less sporty, but using Eco mode for daily driving can make a difference over time.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which makes the engine work harder and use more fuel. Check your tire pressures often and inflate them to the recommended levels on the driver’s side doorjamb. Correctly inflated tires improve fuel efficiency and also extend tire life.

Avoid unnecessary idling. Modern engines are designed to be efficient when running, but idling wastes fuel without going anywhere. If you’re stopped for more than a minute, turn off the engine. The GLA’s start/stop system helps with this, automatically shutting off the engine at stoplights, but you can turn it off if you want.

Drive smoothly and predictably. Quick acceleration and hard braking waste fuel. Anticipate traffic and maintain a steady speed when possible. Using cruise control on the highway can also help improve fuel efficiency by keeping your speed consistent. The smoother the driving, the more fuel-efficient the GLA250 will be.

Schedule regular maintenance. A well-maintained engine runs more efficiently. Make sure your GLA250 gets regular oil changes, air filter replacements, and spark plug services according to the manufacturer’s schedule. A clean air filter, for example, ensures the engine gets enough air, which optimizes combustion and improves fuel economy. See GLA250 MPG across all years.
