With 30 MPG combined, the 2017 Mazda 3 5-Door 2.5L is an efficient choice for drivers who want practicality and fun. It prioritizes driving enjoyment, and its fuel figures show that you don’t have to sacrifice fun to save money at the pump.

City and highway performance

The EPA estimates the 2017 Mazda 3 5-Door 2.5L at 26 MPG in the city and 35 MPG on the highway. It’s important to understand how these numbers translate to real-world scenarios. The 26 MPG city rating suggests this Mazda is well-suited for daily commutes and navigating urban environments. Factors like traffic congestion and frequent stops can drastically impact fuel consumption, but the Mazda 3’s responsive engine and smooth automatic transmission help maintain efficiency in start-stop driving. The 35 MPG highway rating is impressive, making it a comfortable and relatively economical option for longer road trips. This hatchback is equally adept at handling your weekly errands as it is embarking on a weekend adventure. Drivers who frequently find themselves on the open road will find this rating especially appealing. You can find all Mazda fuel economy data on our site.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Mazda 3 5-Door 2.5L at $1,450. This figure is based on driving 15,000 miles per year and using national averages for fuel prices. Keep in mind that your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and gas prices in your region. While $1,450 provides a helpful benchmark, it’s essential to consider your own individual circumstances to get a more accurate picture of what you can expect to spend on fuel annually. This benchmark applies to the specific trim and engine, which is also worth noting when cross-shopping the 3 MPG across all years.

Real-world expectations

Observed fuel economy often differs from EPA estimates. Aggressive driving, carrying extra weight, and even tire pressure can affect your MPG. However, the Mazda 3 generally performs close to its EPA ratings in real-world conditions. Owners report figures around the stated combined MPG, with many achieving even higher numbers on long highway drives when driving conservatively. Drivers who appreciate the Mazda 3’s sporty character might see slightly lower numbers due to more spirited driving, but overall, it’s a predictably efficient vehicle.

How it compares

The Honda Civic Hatchback with the 1.5-liter turbocharged engine achieves an EPA-estimated 34 MPG combined. This makes it a direct competitor and potential alternative for those prioritizing fuel efficiency. The Toyota Corolla Hatchback, another popular choice, reaches 32 MPG combined. While both offer competitive MPG numbers, the Mazda 3 distinguishes itself with its engaging driving dynamics and higher-quality interior. The Volkswagen Golf, known for its refined handling and premium feel, achieves around 29 MPG combined, putting it a bit behind the Mazda in fuel economy but ahead in refinement, depending on the trim. Ultimately, the best choice boils down to individual priorities: fuel efficiency versus driving enjoyment versus overall refinement.

Tips to maximize efficiency

The Mazda 3’s Skyactiv-G engine responds well to smooth, consistent driving. Avoid abrupt acceleration and braking to minimize fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible. This driving style improves fuel economy and enhances the overall driving experience, complementing the car’s balanced handling.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly, especially before long trips. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure for your Mazda 3.

Reduce unnecessary weight in the vehicle. Carrying extra weight places additional strain on the engine, decreasing fuel economy. Remove any items you don’t need, such as sports equipment or rarely used tools. A lighter vehicle is a more efficient vehicle.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate waiting for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t experience any significant delay.

Consider using cruise control on highway drives. Cruise control helps maintain a consistent speed, reducing the fluctuations in throttle input that can negatively affect fuel economy. Engage cruise control on long stretches of open road to optimize your MPG.
