2019 Mercedes-Benz AMG GLA45 4matic: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2019 Mercedes-Benz AMG GLA45 4matic. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 2019 Mercedes-Benz AMG GLA45 4matic. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2019 Mercedes-Benz AMG GLA45 4matic compares

The 2019 Mercedes-Benz AMG GLA45 4matic returns 25 combined MPG. Cars in the Midsize Station Wagons class for the same model year average 22.4 MPG, which puts this car ahead of the class average by about 12%.

The most efficient car in the Midsize Station Wagons class for the 2019 model year is the Volvo V90 FWD at 27 MPG. The bar chart below puts the Mercedes-Benz AMG GLA45 4matic alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2019 model year (across all classes) returns 26.8 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2019 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 600 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Mercedes-Benz AMG GLA45 4matic

The EPA has rated the Mercedes-Benz AMG GLA45 4matic across 7 model years, from 2016 Mercedes-Benz AMG GLA45 4matic through 2023 Mercedes-Benz AMG GLA45 4matic. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

Combined MPG has stayed in roughly the same range across the run, hovering close to 22 MPG.

Specifications

The 2019 Mercedes-Benz AMG GLA45 4matic runs a 2-liter 4-cylinder turbocharged engine paired with a automatic (am7), sending power through 4-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
