29 MPG combined won’t set any fuel economy records, but it’s perfectly acceptable for the 2021 Mercedes-Benz CLA250. This stylish, entry-level luxury coupe (marketed as a “four-door coupe”) prioritizes design and driving experience over efficiency. Buyers in this segment are often more concerned with making a statement and enjoying a quality driving experience rather than saving money at the pump.

City and highway performance

The EPA estimates the CLA250 will achieve 25 MPG in the city and 35 MPG on the highway. The city figure reflects stop-and-go traffic, where the 2.0L turbocharged engine can be less efficient. The highway number is respectable; the CLA’s aerodynamic profile cuts through the air efficiently at higher speeds, allowing the engine to cruise with less effort. The automatic (AM7) transmission also helps by keeping the engine in its most efficient gear. These figures provide a reasonable expectation of what you can achieve whether you’re driving in the city or on a road trip.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz CLA250 at $2,000. This is based on driving 15,000 miles per year, using a national average fuel price. The actual cost will vary depending on driving habits, local fuel prices, and the type of fuel used. $2,000 provides a benchmark for budgeting fuel expenses. Note that this assumes you’re using premium fuel as recommended by Mercedes-Benz, which generally costs more than regular unleaded.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy can vary. Several factors influence MPG, including driving style, traffic, and even tire pressure. Aggressive acceleration, hard braking, and prolonged idling negatively impact fuel consumption. Adopting a smoother driving style can help you get closer to, or even exceed, the EPA estimates. Maintaining proper tire inflation and ensuring the CLA250 is properly maintained will also contribute to optimal fuel efficiency.

The CLA250 is designed for driving enjoyment, so avoid constantly exploiting its performance if maximizing MPG is a priority.

How it compares

The CLA250’s fuel economy is in the middle of the pack for compact luxury cars. The BMW 228i Gran Coupe, a direct competitor, achieves a combined EPA rating of 28 MPG. The Audi A3 sedan boasts a slightly better 32 MPG combined. The Acura Integra, while not a direct luxury competitor, is even more fuel-efficient at 33 MPG combined, showing that prioritizing fuel economy can improve gas mileage greatly. For shoppers who value performance more than fuel savings, the CLA250 is a good choice. For those wanting the best efficiency, exploring other options might be wise.

Tips to maximize efficiency

The key to maximizing fuel efficiency in the CLA250 is smooth and consistent throttle inputs. Avoid sudden acceleration, and anticipate traffic to minimize braking. The more consistently you drive at a steady speed, the closer you’ll get to the EPA’s highway fuel economy rating.

Use the CLA250’s driving modes. The “Comfort” or “Eco” modes will prioritize fuel efficiency by adjusting throttle response and transmission mapping. This can make a difference in city driving, where stop-and-go traffic can quickly drain fuel. Experiment to see which mode best suits your driving style while still providing adequate performance.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly, especially during temperature changes, and inflate them to the pressure listed on the door jamb sticker.

Reduce unnecessary weight in the vehicle. Excess cargo adds to the vehicle’s weight, which negatively impacts fuel efficiency. Remove any items you don’t need regularly to lighten the load and improve MPG. Also consider the weight of your wheels, as larger, heavier wheel/tire combinations can reduce economy.

Regular maintenance is critical. Keep up with scheduled maintenance tasks, such as oil changes and air filter replacements. A well-maintained engine operates more efficiently, which translates to better fuel economy. For more information on the CLA250, you can also view CLA250 MPG across all years.
