The 2020 Mazda 3 4-Door 2WD 2.5L gets 30 MPG combined. It’s a reasonable number, not class-leading but not particularly poor either. It reflects the trade-offs Mazda made, favoring driving enjoyment and styling over maximizing efficiency. This Mazda 3 appeals to drivers who value a responsive engine, a well-tuned chassis, and a premium-feeling interior within an attractive design. They accept slightly higher fuel costs to experience the Mazda 3’s unique feel.

City and highway performance

EPA estimates provide more detail: 26 MPG in the city and 35 MPG on the highway. The city MPG reflects the demands of stop-and-go traffic, where the 2.5L engine uses more fuel to accelerate. The highway rating suggests the engine operates more efficiently at consistent speeds, helped by the automatic transmission selecting the ideal gear for steady cruising. The Mazda 3 isn’t especially thirsty in urban driving, and it achieves respectable mileage on longer trips.

Annual fuel cost

The EPA calculates the annual fuel cost for this 2020 Mazda 3 at $1,450. This estimate assumes 15,000 miles driven per year, using average national fuel prices. This provides a useful comparison point, but your actual cost will vary based on local fuel prices and your individual driving habits. Consider $1,450 a guideline to compare the Mazda 3 to other vehicles and evaluate its affordability. Fuel prices change, influencing your expenses.

Real-world expectations

EPA estimates are valuable, but real-world fuel economy varies. Driving style, terrain, weather, and maintenance all affect MPG. Quick acceleration, hard braking, and high speeds reduce fuel efficiency. Smooth, consistent driving and regular maintenance, like proper tire inflation and oil changes, can help you reach or even exceed EPA estimates. Keep these factors in mind when deciding if this Mazda 3 suits your needs.

How it compares

The 2020 Mazda 3’s fuel economy is competitive in its class. The Honda Civic Sedan achieves up to 42 MPG highway in its most efficient version. While this Mazda 3’s MPG on the highway is not as high as the Civic’s best, you can browse all Mazda fuel economy data to see it beats other Mazda models with larger engines. The Toyota Corolla offers up to 40 MPG highway as a hybrid. The Mazda prioritizes a more engaging driving feel and a better interior, factors that can be viewed on 3 MPG across all years. The Hyundai Elantra achieves up to 43 MPG highway, making it a good choice for maximum efficiency. Mazda 3 buyers often accept slightly less fuel economy for its superior driving dynamics and interior quality that those other trims do not have.

Tips to maximize efficiency

Gentle acceleration and braking are key to maximizing fuel economy in the Mazda 3. Avoid sudden starts and anticipate traffic to minimize braking. It is easy to be tempted to accelerate quickly to take advantage of the 2.5L engine, but resisting this will visibly save fuel.

Maintain correct tire pressure. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure often and inflate to the recommended level which is on the sticker in the driver’s side doorjamb. This will improve fuel economy.

Reduce weight in the car. Extra cargo adds to the load, which lowers fuel efficiency. Remove unnecessary items from the trunk or backseat. By reducing weight, you’ll improve the Mazda 3’s MPG and save more.

Use cruise control on the highway. Keeping a consistent speed helps optimize fuel use. Cruise control reduces changes in acceleration, which leads to more efficient fuel use. Only use cruise control when weather and traffic conditions are safe.

Do all scheduled maintenance. Routine maintenance, like oil and air filter changes, ensures the engine runs efficiently. A clean air filter allows good airflow, and fresh oil reduces friction. Regular maintenance helps to keep the Mazda 3’s MPG high and extends its life.
