30 MPG combined isn’t going to set any records, but it’s a respectable figure for the 2016 Mazda 3 5-Door 2.5L 4-cyl, a car that prioritizes driving engagement over being extremely economical. Owners of this specific Mazda 3 configuration aren’t solely focused on saving every last penny at the pump; they appreciate a responsive engine, a well-tuned chassis, and a hatchback’s versatility, and they accept slightly less stellar mileage as the price of admission.

City and highway performance

The EPA estimates this Mazda 3 at 27 MPG in the city and 36 MPG on the highway. These figures reflect the car’s behavior in different driving environments. The city number acknowledges that the 2.5L engine, though relatively efficient, requires more fuel during stop-and-go traffic and acceleration. The 36 MPG highway figure demonstrates the engine’s ability to cruise efficiently at higher speeds, using of the automatic (S6) transmission’s higher gear ratios and the Mazda 3’s relatively light weight. It also shows the benefits of Mazda’s Skyactiv technology, which optimizes engine operation for both power and fuel economy.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2016 Mazda 3 5-Door 2.5L is $1,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s an estimate, of course, and your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and prevailing gas prices in your area. However, it provides a useful benchmark for comparing the Mazda 3’s fuel costs to those of other vehicles.

Real-world expectations

While the EPA estimates provide a standardized basis for comparison, real-world fuel economy often differs. Drivers who frequently accelerate quickly or spend a significant amount of time in heavy traffic may see lower MPG than the EPA estimates. Those with a light foot and predominantly highway driving can often exceed the official figures. Careful monitoring of your driving habits and fuel consumption can provide a more accurate understanding of the 2016 Mazda 3 5-Door 2.5L’s fuel economy in your specific circumstances. Comparing this model to the 3 MPG across all years shows the range of MPG figures for this platform.

How it compares

The 2016 Mazda 3 5-Door 2.5L’s 30 MPG combined stacks up against its competitors in interesting ways. A 2016 Honda Civic Hatchback with the 1.5L turbo engine achieves around 34 MPG combined, offering slightly better fuel economy for those wanting to save gas. On the other hand, a 2016 Ford Focus ST, while offering significantly more power and performance, delivers around 25 MPG combined. The Mazda 3 strikes a balance between these extremes, offering a more engaging driving experience than the Civic while remaining more fuel-efficient than the Focus ST. Consider also the Toyota Corolla iM from the same era, which offers similar utility but with a 28 MPG combined rating, slightly behind the Mazda. Buyers considering all Mazda fuel economy data should weigh these different choices carefully.

Tips to maximize efficiency

Use the Mazda 3’s “Skyactiv” design. The engine is optimized for efficiency through high compression, direct injection, and reduced internal friction. Avoid excessive idling, as it consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, it’s generally more efficient to turn off the engine.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure at least once a month and inflate your tires to the manufacturer’s recommended pressure, which can be found on a sticker inside the driver’s side door jamb.

Use cruise control on the highway whenever possible. Maintaining a steady speed can significantly improve fuel economy compared to varying your speed constantly. and avoid aggressive acceleration and braking. Gradual acceleration and smooth braking conserve fuel.

Lighten your load. Carrying unnecessary weight in your vehicle reduces fuel economy. Remove any items from your trunk that you don’t need regularly. Even small amounts of weight add up over time.

Ensure your car is properly maintained. Regular oil changes, air filter replacements, and spark plug replacements can help maintain optimal engine performance and fuel economy.
