22 MPG combined is what you can expect if you buy the 2022 Mercedes-Benz AMG GLA45 4matic. To be clear, this isn’t a purchase made for saving money. It’s a calculated choice for drivers who want high performance and a premium brand in a small package. This isn’t just a car for errands, it’s a hot hatch that looks like a crossover, and its fuel economy shows that trade-off.

City and highway performance

The EPA estimates 19 MPG in the city and 25 MPG on the highway. The city number is probably more important. This vehicle will probably spend a lot of time in cities. Because the GLA45 responds quickly to the throttle and the engine is powerful, getting 19 MPG might be hard. On the highway, the 25 MPG is better, allowing for a comfortable driving range. But, if you avoid using the engine’s full power, your mileage will stay close to that number.

Annual fuel cost

The EPA says the estimated annual fuel cost for the 2022 Mercedes-Benz AMG GLA45 4matic is $2,650. This is calculated assuming 15,000 miles driven per year and using the national average fuel price. Remember that premium fuel is required, which raises the total cost. Also, your actual annual fuel cost could be higher than the EPA estimate depending on how you drive. Driving hard and taking many short trips can quickly empty the fuel tank, making you exceed the average.

Real-world expectations

Don’t expect to always match the EPA numbers. The AMG GLA45 makes drivers want to use its performance, which lowers fuel economy. Owners often report getting around 17-20 MPG in mixed driving. If you tend to accelerate quickly, expect the lower end of that range. Regular highway driving with careful throttle control might get you close to the EPA’s 25 MPG. The turbocharged engine’s quick response and the exciting exhaust sound are often too tempting for drivers, making careful driving difficult.

How it compares

The AMG GLA45 is in a niche market, combining performance and practicality. Competitors like the BMW X2 M35i, which gets 25 MPG combined, offer slightly better fuel economy. The Audi SQ3, which isn’t currently sold in the US, could also be more efficient, potentially reaching 27 MPG combined. Within the Mercedes-Benz lineup, looking at all Mercedes Benz fuel economy data can show more efficient options if fuel economy is more important. However, these alternatives often lack the GLA45’s high performance and AMG-specific features. For detailed comparisons, see AMG MPG across all years. The slightly better fuel economy compared to the GLA45 isn’t always enough to persuade buyers who like the unique characteristics of the GLA45. The decision depends on whether performance or fuel efficiency is more important.

Tips to maximize efficiency

Avoid using the engine’s turbo boost constantly. The AMG GLA45 is fun to drive, but accelerating at full throttle uses a lot of fuel. Accelerating gently and anticipating traffic flow can make a difference over time.

Make sure the tires have the correct pressure. The right tire pressure reduces rolling resistance, improving fuel efficiency and handling. Check the tire pressure regularly and set it to the manufacturer’s recommended level, especially when the temperature changes.

Avoid idling too long. Letting the engine idle for a long time wastes fuel. If you’re stopped for more than a minute, turn off the engine. The AMG GLA45’s engine starts quickly, making restarts efficient.

Use the ECO drive mode when you can. The AMG GLA45 has different drive modes, including ECO mode that focuses on fuel efficiency. While it might slightly reduce performance, it can help save fuel when you don’t need as much power.

Remove extra weight from the vehicle. More weight increases the fuel needed to accelerate and maintain speed. Remove unnecessary items from the trunk and passenger areas to reduce the vehicle’s weight.
