26 MPG combined is acceptable fuel economy for the 2018 Mercedes-Benz GLA250 4matic, but it’s important to understand why. This isn’t a vehicle purchased for its fuel efficiency. This is an entry-level luxury crossover with a premium badge, offering enhanced driving dynamics and all-weather confidence thanks to its 4matic all-wheel-drive system. Buyers prioritize those features, along with the Mercedes-Benz brand, and are willing to trade some fuel efficiency for the overall package.
City and highway performance
The EPA estimates the GLA250 4matic’s fuel economy at 23 MPG in the city and 31 MPG on the highway. This difference reflects the nature of the turbocharged 2.0L four-cylinder engine. In urban driving, stop-and-go traffic reduces fuel efficiency, as the engine works harder to accelerate. However, on the open road, the engine settles into a more efficient cruising speed. The eight-speed automatic transmission plays a key role here, optimizing gear selection for both performance and fuel conservation. GLA drivers will likely be happy on longer highway trips as they pass gas stations.
Annual fuel cost
The annual fuel cost for the 2018 Mercedes-Benz GLA250 4matic is estimated at $2,250. This figure is based on the EPA’s assumption of 15,000 miles driven per year, with a combination of city and highway driving, using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. Use this as a comparison point when looking at other cars in the Mercedes Benz fuel economy data.
Real-world expectations
While the EPA estimates are a good comparison point, real-world fuel economy can change. Aggressive driving, carrying heavy loads, and prolonged idling can all hurt fuel consumption. Tire pressure, outside temperature, and even the use of air conditioning can cause further changes. Many GLA250 4matic owners report fuel economy numbers close to the EPA estimates under normal driving conditions. However, drivers using Sport mode might see numbers in the low 20s. Compare GLA250 MPG across all years before buying.
How it compares
The GLA250 4matic’s fuel economy is competitive in the subcompact luxury SUV segment, but not the best. The BMW X1 xDrive28i of the same year gets 25 MPG combined, slightly better than the GLA250. The Audi Q3 gets around 23 MPG combined. The Lexus NX 300h hybrid offers much better fuel economy (31 MPG combined), but costs more and offers a different driving experience. The difference in MPGs can be substantial for those who drive many miles per year. Buyers who want better fuel efficiency might consider these alternatives, but may have to compromise on performance and driving dynamics.
Tips to maximize efficiency
Drive smoothly and gently. Rapid acceleration and hard braking use more fuel. Watch traffic and maintain a steady pace when you can. Avoid idling for too long; if you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine.
Make sure your tires are properly inflated to the recommended pressure, which can be found on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure often, especially when the temperature changes.
Use air conditioning less. The climate control system puts extra load on the engine, hurting fuel efficiency. Use it carefully and select recirculating air when you can. On cooler days, open the windows instead of using the AC.
Schedule regular maintenance. A poorly maintained engine is less efficient. Follow the manufacturer’s maintenance schedule, including oil changes, air filter changes, and spark plug changes. A well-maintained engine runs more smoothly and efficiently.
Drive with less weight. Carrying unnecessary weight reduces fuel economy. Remove extra cargo from the vehicle, such as items in the trunk or backseat that are not needed for the trip. Weight adds up, especially in cars with smaller engines.
