The 2024 Mazda 3 4-Door with the 2.5L engine and front-wheel drive gets 31 MPG combined. While not a dedicated economy car, this compact sedan prioritizes driving enjoyment while remaining reasonably efficient. This number appeals to buyers who want a stylish and fun-to-drive small car and accept average fuel efficiency for Mazda’s driving dynamics and upscale interior.

City and highway performance

The EPA estimates 27 MPG in the city and 37 MPG on the highway, reflecting the Mazda 3’s everyday practicality. The city figure acknowledges the 2.5L engine provides sufficient power for urban driving, even if fuel consumption isn’t as low as a Prius. On the highway, the 37 MPG rating shows the Mazda 3 is comfortable and efficient for longer trips. The six-speed automatic transmission helps achieve these numbers with its smooth shifts and decent fuel economy at cruising speeds. This is important for commuters who spend significant time on highways.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mazda 3 2.5L 2WD at $1,400. This is based on driving 15,000 miles per year and national average fuel prices. Fuel costs will vary depending on driving habits and local fuel prices. This number provides a useful comparison point against other vehicles in its class.

This $1,400 figure is based on a mix of city and highway driving, aligning with typical usage and making it relevant for potential buyers.

Real-world expectations

Real-world fuel economy can vary from EPA estimates. Aggressive driving, stop-and-go traffic, and weather conditions can all affect fuel economy. However, the Mazda 3’s proven powertrain results in consistent and predictable fuel consumption.

Most drivers will likely see numbers close to the EPA estimates if they drive reasonably efficiently. This predictability is valued by many Mazda 3 owners.

How it compares

The Honda Civic sedan achieves an EPA-estimated 35 MPG combined in its LX trim, slightly better than the Mazda. The Toyota Corolla sedan boasts up to 34 MPG combined in its LE trim, also exceeding the Mazda, but some drivers find its driving experience less engaging. The Hyundai Elantra can achieve up to 37 MPG combined in its Blue trim and is known for its value. These comparisons are important to Mazda 3 buyers because they often consider these vehicles. They weigh fuel economy against driving dynamics, interior quality, and styling.

Someone dedicated purely to fuel economy might choose the Elantra or Corolla. Mazda buyers understand the trade-offs they are making for driving experience and interior quality.

Tips to maximize efficiency

Use the Mazda 3’s “Sport” mode carefully. While it enhances throttle response, it also lowers fuel economy. Limit its use if maximizing MPG is the goal.

Around town, avoid quick acceleration. The 2.5L engine can use a lot of fuel when driven aggressively.

Keep your tires properly inflated. Under-inflated tires increase rolling resistance, which reduces fuel economy. Check tire pressure regularly and maintain the recommended level, found on the sticker inside the driver’s side door jamb. Proper inflation also extends tire life and improves handling.

Minimize air conditioning use, especially on shorter trips. Air conditioning puts strain on the engine, lowering fuel economy. On mild days, consider opening the windows or the fan. The Mazda 3’s quiet cabin at highway speeds makes this possible.

Service your Mazda 3 according to the manufacturer’s schedule. Regular maintenance, like oil changes and air filter replacements, keeps the engine running efficiently. Neglecting maintenance can reduce fuel economy and cause engine problems.
