The 2020 Mazda 3 5-Door 4WD 2.5L gets 27 MPG combined. This figure might not excite fuel efficiency seekers, but it’s a reasonable trade-off for compact hatchback practicality combined with all-wheel drive and the power of the 2.5-liter engine. This Mazda 3 prioritizes a fun driving experience, a high-quality interior, and usability in all seasons. The ideal buyer values style, performance, and security, and they’re willing to accept decent, but not class-leading, fuel economy in return.

City and highway performance

The EPA estimates the 2020 Mazda 3 5-Door 4WD 2.5L at 24 MPG in the city and 32 MPG on the highway. The city MPG reflects the realities of stop-and-go driving, where the all-wheel-drive system and larger engine use slightly more fuel. The highway MPG is more respectable, showing the engine’s efficiency at steady speeds the six-speed automatic transmission is geared to balance performance and fuel economy, which helps it achieve 32 MPG on long trips. Continuously variable transmissions (CVTs) often deliver better MPG, but Mazda has stuck with a conventional automatic, placing more importance on driving feel than marginal efficiency gains.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mazda 3 5-Door 4WD 2.5L at $1,600. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Individual fuel costs will change based on local fuel prices and personal driving habits. Drivers who primarily drive in the city may find their annual fuel cost exceeds this estimate, and those with mostly highway miles may spend less. The $1,600 figure provides a useful benchmark for comparing running costs with other vehicles in its class, but your actual expenses will depend on your specific circumstances.

Real-world expectations

EPA estimates provide a standardized benchmark, but real-world fuel economy often differs. Many factors influence the MPG you’ll actually achieve, including driving style, traffic conditions, weather, and even tire pressure. It’s reasonable to expect a slight difference from the official figures.

An aggressive driving style with frequent acceleration will likely decrease fuel economy, while smoother, more deliberate driving can help you get closer to the EPA estimates. Colder weather can negatively impact MPG, particularly on shorter trips, as the engine needs more time to reach its optimal operating temperature. Checking tire pressures regularly is also critical, as underinflated tires increase rolling resistance and reduce fuel efficiency. Owners often report numbers within 1-2 MPG of the EPA’s estimates under typical driving conditions. See 3 MPG across all years.

How it compares

In the compact hatchback all-wheel-drive segment, the Mazda 3 strikes a particular balance. The Subaru Impreza hatchback, a direct competitor with standard all-wheel drive, achieves a slightly better 31 MPG combined in its automatic form. The Impreza sometimes sacrifices driving engagement for efficiency. The Nissan Kicks, while not offering AWD, gets a significantly better 33 MPG combined, but it does so with a less powerful engine and a different target customer. Even front-wheel-drive versions of the Honda Civic Hatchback can reach around 35 MPG on the highway, indicating where the Mazda 3 places its priorities.

The Mazda 3’s fuel economy is a calculated trade-off for the more advanced drivetrain, refined interior, and more responsive driving experience. The buyer of this Mazda isn’t only focused on MPG; they’re after a more complete package that includes performance, style, and all-weather capability. Also check out all Mazda fuel economy data.

Tips to maximize efficiency

Anticipate traffic flow and avoid sudden acceleration and braking. The Mazda 3’s responsive engine can be tempting, but smooth, consistent driving will significantly improve fuel economy. Use cruise control on the highway to maintain a steady speed and minimize variations in throttle input, this is helpful on long drives where it’s easy for speed to creep up without noticing.

Ensure your tires are properly inflated. Check the tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. Properly inflated tires reduce rolling resistance and improve fuel efficiency. Think about using low-rolling-resistance tires when it’s time for replacement.

Reduce unnecessary weight. Carrying extra weight in your vehicle reduces fuel economy. Remove any unnecessary items from the trunk and back seats to lighten the load. Even small amounts of weight can add up over time and impact your MPG.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute, turn off the engine. The Mazda 3’s engine restarts quickly and smoothly, making this a simple way to save fuel. This is especially useful in city driving with frequent stops.

Use the air conditioning sparingly. The air conditioning system puts a significant load on the engine, reducing fuel economy. When possible, use the ventilation system or open the windows instead. When air conditioning is necessary, use it on the lowest comfortable setting.
