31 MPG combined won’t set any records, but for the 2023 Mazda 3 4-Door with the 2.5L engine, it’s a carefully considered balance. This car prioritizes driving enjoyment and a premium feel, even if that means sacrificing some fuel efficiency. Buyers often accept slightly fewer miles per gallon for a more engaging and refined driving experience.
City and highway performance
The EPA estimates are 28 MPG in the city and 37 MPG on the highway. The city figure reflects the 2.5L engine’s responsiveness in stop-and-go traffic. It has enough power to feel quick and nimble, even if it’s not quite as thrifty as some economy-focused rivals. The highway MPG is more impressive, showcasing the engine’s efficiency at steady speeds. The smooth-shifting six-speed automatic transmission helps keep the engine in its optimal rev range for both performance and fuel conservation during highway cruising.
Annual fuel cost
The EPA estimates that the annual fuel cost for this Mazda 3 configuration is $1,400. This is based on driving 15,000 miles per year and using national average fuel prices. Keep this in mind when budgeting and compare it to other vehicles. This number can vary based on your driving habits and local fuel prices, but the official figure provides a baseline to compare this car against 3 MPG across all years.
Real-world expectations
The EPA estimates provide a good benchmark, but real-world fuel economy varies depending on driving style, traffic conditions, and terrain. Owners who prioritize smooth acceleration and consistent speeds are more likely to achieve figures closer to the EPA estimates. However, aggressive drivers who frequently accelerate hard will likely see lower numbers. The Mazda 3’s sporty character can encourage more spirited driving, which can impact fuel economy. Individual results are likely to vary a few MPG in either direction.
How it compares
Compared to its competitors, the Mazda 3’s fuel economy is respectable but not class-leading. A Honda Civic with the 1.5L turbocharged engine routinely achieves around 42 MPG on the highway, a significant advantage for those who prioritize lower fuel costs. A Toyota Corolla Hybrid gets even better efficiency. However, the Mazda 3’s 2.5L engine delivers more power than the base engines in either of those vehicles. The Hyundai Elantra with its standard 2.0L engine lands in the middle, with both power and MPG figures lower than the Mazda. Therefore buyers who value the Mazda 3’s upscale interior and driving dynamics often believe the slight MPG tradeoff relative to competitors is worthwhile. For more efficiency ratings, consult all Mazda fuel economy data.
Tips to maximize efficiency
Use cruise control on the highway whenever possible. Maintaining a consistent speed avoids unnecessary acceleration and braking, which can significantly improve fuel economy. This is especially important on long trips.
Avoid aggressive acceleration and braking. The Mazda 3’s responsive engine can be tempting, but gentle acceleration and smooth braking will conserve fuel. Anticipate traffic flow and avoid sudden stops.
Keep your tires properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and inflate them to the recommended level found on the sticker inside the driver’s door.
Reduce unnecessary weight. Carrying extra cargo in your vehicle can reduce fuel economy. Remove any unnecessary items from your trunk and passenger compartment to lighten the load. Consider lightening larger loads by removing roof racks if you never use them.
Consider using the “Normal” driving mode. The Mazda 3 may offer various driving modes, some of which prioritize performance over fuel economy. Selecting the “Normal” mode will optimize the car’s settings for a balance of performance and efficiency.
