The 2019 Mazda 3 4-Door 4WD 2.5L gets 28 MPG combined. While it won’t win any hypermiling contests, this is a respectable figure for a compact sedan that offers all-wheel drive and a punchy 2.5-liter engine. This isn’t the most fuel-efficient Mazda 3; it’s for drivers who want confident handling and responsive power, even if it means using more gas. The buyer choosing this configuration accepts a small fuel economy trade-off for year-round grip and engaging performance.

City and highway performance

EPA estimates for the 2019 Mazda 3 4-Door 4WD 2.5L are 25 MPG in the city and 33 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine works harder and the all-wheel-drive system might engage more frequently, especially in bad weather. The highway number shows the engine’s efficiency at cruising speeds, helped by the smooth six-speed automatic transmission. Some competitors offer more gears or continuously variable transmissions, but Mazda uses a traditional automatic. This likely contributes to the slightly lower highway MPG compared to some rivals, but provides a more engaging driving experience.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mazda 3 4-Door 4WD 2.5L to be $1,550. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may be higher or lower depending on your driving habits, the type of roads you typically drive on, and the price of gasoline in your area. The $1,550 figure is a useful baseline for comparing the running costs of this vehicle to other options.

Real-world expectations

EPA estimates provide a standardized benchmark, but real-world fuel economy can vary. Aggressive driving, frequent short trips (especially in cold weather), carrying heavy loads, and using accessories like air conditioning can all hurt fuel efficiency. However, drivers who adopt a more fuel-conscious driving style and keep their vehicle properly maintained can often get figures close to, or even slightly better than, the EPA’s estimates. The 2.5-liter engine, while strong, isn’t overly stressed in normal driving, and the automatic transmission is generally efficient. Monitoring your fuel consumption can provide a more accurate picture of what to expect.

How it compares

The 2019 Mazda 3 4-Door 4WD 2.5L competes well with other compact cars with all-wheel drive. The Subaru Impreza, a perennial AWD competitor, gets around 31 MPG combined with its CVT transmission. The Nissan Rogue Sport, a subcompact SUV, offers AWD and gets around 27 MPG combined. However, neither provides the same driving feel as the Mazda 3. If lower fuel costs are the priority, the front-wheel-drive Mazda 3 with the 2.0-liter engine gets much higher figures. You can view 3 MPG across all years. Looking at all Mazda fuel economy data shows that the AWD 2.5L is the least efficient Mazda 3 variant, but it delivers a blend of capability and fun that justifies the trade-off for many.

Tips to maximize efficiency

Minimize aggressive acceleration and braking. The Mazda 3 is responsive, but using that power frequently will diminish fuel economy. Anticipate traffic flow and maintain a steady speed whenever possible. This reduces fuel consumption, especially in city driving, and keeps the engine within its most efficient operating range.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, which forces the engine to work harder and reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels listed on the driver’s side door jamb. This is a simple and effective way to improve your MPG.

Reduce the amount of weight you carry in the vehicle. Extra weight increases the amount of energy required to move the car, leading to lower fuel economy. Remove any unnecessary items from the trunk and passenger area. Every little bit helps, especially for frequent city driving.

Use the air conditioning sparingly. The A/C system is effective, but it also places a load on the engine, reducing fuel efficiency. When possible, use the ventilation system instead, especially at lower speeds. Recirculating air can also reduce the strain on the A/C system.

Keep up with regular maintenance. A properly maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. This ensures that all components are working and helping the car get better gas mileage.
