The 2018 Mercedes-Benz GLA250’s 27 MPG combined rating won’t win any hypermiling competitions, but it’s a respectable figure for a small luxury crossover that values style and a premium driving experience over ultimate thriftiness. GLA250 buyers aren’t necessarily seeking maximum fuel efficiency; they prioritize the Mercedes-Benz brand, the elevated driving position, and the overall refinement.

City and highway performance

The EPA estimates for the 2018 GLA250 are 24 MPG in the city and 33 MPG on the highway. The city figure reflects the stop-and-go driving conditions that many GLA250 owners will encounter during their daily commutes. The turbocharged 2.0L engine, paired with a responsive automatic transmission, provides ample low-end torque, making it feel peppy and agile in urban environments.

On the highway, the GLA250 settles into a comfortable cruise, maintaining a steady speed with minimal effort. The 33 MPG highway rating is achievable, especially on longer road trips where speeds are consistent.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2018 GLA250 is estimated at $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Of course, your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. However, the $2,150 estimate provides a useful benchmark for comparing the GLA250’s fuel costs to those of other vehicles in its class.

Real-world expectations

While the EPA estimates provide a good starting point, real-world fuel economy can vary. Expect to see figures close to the EPA’s numbers if you drive conservatively and follow the speed limit. However, aggressive driving, frequent short trips, and carrying heavy loads can all negatively impact fuel economy. All-wheel drive models may also see slightly lower fuel economy compared to the standard front-wheel drive GLA250.

Most owners report that achieving the combined 27 MPG is realistic with a mix of city and highway driving. For those looking closer at the model, check out GLA250 MPG across all years.

How it compares

In the world of small luxury crossovers, the 2018 GLA250’s fuel economy is competitive, but not class-leading. The BMW X1, for instance, achieves a similar 25 MPG combined. However, the Lexus NX 300h hybrid boasts a considerably higher 31 MPG combined. The Audi Q3, before its redesign, landed around 23 MPG combined, a bit lower than the GLA250. These comparisons are important to GLA250 buyers because they represent tangible operating costs over the life of the vehicle. While comfort, safety, and brand image weigh heavily in the decision process, fuel economy remains a consistent, underlying concern.

Tips to maximize efficiency

The GLA250 benefits from smooth and steady acceleration. Avoid aggressive starts and hard braking to conserve fuel. The turbocharged engine responds well to gentle throttle inputs, allowing you to maintain a good pace without demanding excessive power.

Take advantage of the GLA250’s ECO drive mode, if equipped. This mode optimizes various vehicle settings, such as throttle response and transmission shift points, to prioritize fuel efficiency. It subtly encourages more efficient driving habits without significantly impacting performance.

Proper tire inflation is critical for maximizing fuel economy. Check your tire pressure regularly and ensure it matches the recommended levels, which are typically found on a sticker inside the driver’s side door jamb. Underinflated tires increase rolling resistance, leading to reduced fuel efficiency. Remember to also stay on top of your regular maintenance, checking all Mercedes Benz fuel economy data will allow you to stay on top of manufacturer information.

Reduce unnecessary weight in the vehicle. Carrying around heavy items in the trunk or cargo area can negatively impact fuel economy. Remove any items that you don’t need to carry on a regular basis to lighten the load and improve efficiency.

Minimize idling time. If you’re stopped for more than a minute or two, consider turning off the engine. Idling consumes fuel without covering any distance. This is especially relevant in urban environments with frequent stoplights and traffic congestion.
