28 MPG combined is a respectable figure for the 2015 Mercedes-Benz GLA250. This isn’t a hybrid or a dedicated economy car; it’s a stylish, entry-level luxury crossover designed to appeal to younger buyers or empty-nesters downsizing without sacrificing premium features. Fuel efficiency is a consideration, but not the primary driver in their purchase. They want the Mercedes star on the hood, the elevated driving position, and the available tech, and the GLA250 delivers that with reasonable running costs.

City and highway performance

The EPA estimates for the 2015 GLA250 are 25 MPG in the city and 34 MPG on the highway. The city figure suggests the engine’s stop/start system and the responsiveness of the 2.0L turbo are working effectively in stop-and-go traffic. That 34 MPG highway number is achievable on long road trips, provided you resist the urge to frequently exploit the car’s peppy acceleration for passing maneuvers. The seven-speed automatic transmission (AM7) definitely plays a role here, keeping the engine in its sweet spot for both performance and efficiency. It’s a smooth-shifting unit that isn’t afraid to downshift when needed, contributing to a pleasant driving experience whether you’re commuting or cruising.

Annual fuel cost

The EPA estimates that the 2015 Mercedes-Benz GLA250 will cost $2,050 per year in fuel. This calculation is based on driving 15,000 miles annually, using the EPA’s combined MPG rating, and factoring in national average fuel prices. Keep in mind that this is an estimate and your actual fuel costs might vary depending on your driving habits, location, and current gasoline prices. However, the $2,050 figure provides a useful benchmark for comparing the GLA250’s running costs to other vehicles in its class.

Real-world expectations

While the EPA estimates provide a standardized benchmark, expect some variance in real-world driving. Aggressive driving, frequent short trips, and consistently using Sport mode will all negatively affect fuel economy. Conversely, practicing smooth acceleration, anticipating traffic flow, and using cruise control on the highway can help you get closer to, or even exceed, the EPA’s estimates. Many owners report achieving fuel economy within a few MPG of the EPA ratings, which speaks to the GLA250’s efficiency in practical driving conditions. Checking GLA250 MPG across all years, you’ll find consistency between the EPA estimates and owner reported results, suggesting the 2015 model is representative of the vehicle’s overall performance.

How it compares

In 2015, the GLA250 faced stiff competition in the entry-level luxury crossover segment. The BMW X1 xDrive28i, another popular choice, delivers around 25 MPG combined. The Audi Q3, known for its stylish design, offers similar fuel economy numbers at around 23 MPG combined on premium trims. The Lexus NX 200t offers similar fuel economy at around 25 MPG combined. These numbers demonstrate that buyers are cross shopping these brands and that, they’re generally willing to accept a slightly lower MPG in exchange for the luxury features, brand cachet, and overall driving experience these vehicles provide. Mercedes-Benz, BMW, and Lexus buyers are often drawn to their vehicles’ image, advanced technology, and refined interiors.

Tips to maximize efficiency

Take advantage of the GLA250’s ECO start/stop system. It shuts off the engine at stoplights and restarts it when you lift your foot from the brake. This reduces fuel consumption in city driving, where idling can waste a substantial amount of gasoline. Make sure the hood is fully clipped open when working on the car to make sure that it will restart correctly every time.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the recommended pressure, which you can find on the sticker located on the driver’s side doorjamb. Remember to check tire pressures when the tires are cold for the most accurate reading.

Drive smoothly and avoid aggressive acceleration. Rapid acceleration and hard braking consume significantly more fuel. Anticipate traffic and accelerate gradually, allowing the engine to operate efficiently. Smooth driving not only improves fuel economy but also enhances the overall driving experience.

Reduce unnecessary weight. Carrying excess weight in your vehicle reduces fuel efficiency. Remove any unnecessary items from the trunk and passenger compartment to lighten the load. Every extra pound adds up, especially during city driving.

Plan your routes strategically. Avoid peak traffic hours and choose routes that minimize stop-and-go driving. Using navigation apps to find the most efficient route can save you time and fuel. Combining errands into a single trip can also help reduce fuel consumption by minimizing cold starts, which are less efficient.
