Mazda 3 Gas Tank Capacity & Driving Range (2004–2025)

We deliver the most comprehensive and deeply detailed guide on Mazda 3 fuel-tank capacities and real-world driving range across all generations and trims. This breakdown consolidates every key figure, giving drivers, buyers, and enthusiasts a definitive reference for planning long trips, comparing trims, or evaluating efficiency.

Mazda 3 Fuel Tank Capacity at a Glance

The Mazda 3’s gas-tank size has evolved over the years, ranging from 12.0 gallons on certain modern AWD turbo trims to 15.9 gallons on some older 2.5-litre variants. Despite the downsizing in more recent years, improved Skyactiv efficiency ensures consistently strong ranges.

Typical ranges across the lineup include:

• City range: ~261 to 406 miles
• Highway range: ~362 to 580 miles

Fuel Tank Capacity by Generation

First Generation (2004–2009)

Mazda introduced the first-generation 3 with consistent tank sizing:

• 14.5 gallons across most trims
• City range typically above 260 miles
• Highway range slightly above 360 miles

These early models prioritised practicality and long-range capability before efficiency technology matured.

Second Generation (2010–2013)

The second-gen Mazda 3 offered the largest tanks in the model’s history, with variations based on engine and trim.

Tank sizes included:

• 14.5 gallons
• 15.9 gallons (for select 2.5L trims)

Driving ranges:

• City range: ~286 miles
• Highway range: up to ~580 miles

The combination of larger tanks and respectable mpg delivered exceptional long-distance capability, particularly for highway cruising.

Third & Fourth Generations (2014–2020)

Mazda transitioned to improved efficiency and reduced weight, leading to smaller tank sizes.

Typical capacities:

• 13.2 gallons on most trims

These models still maintained strong fuel economy despite the smaller tank.

Modern Mazda 3 (2021–2025)

Recent model years show a split between drivetrain and trim types.

Fuel-tank capacities:

• 12.0 gallons (mostly AWD / turbo models)
• 12.7 gallons (certain AWD trims)
• 13.0–13.2 gallons (FWD models)

Driving ranges:

• City: ~276 to 370 miles
• Highway: ~372 to 488 miles

This demonstrates Mazda’s emphasis on efficiency rather than relying solely on larger tanks.

Fuel Tank Capacity Trends Over Time

    C --> D[2021–2025: ~12.0 to 13.2 gal]

This visual highlights the shift from large tanks to smaller but more efficient systems as Mazda’s Skyactiv engines matured.

Why Mazda Shrunk the Fuel Tank but Maintained Range

Even with a tank reduced from ~15.9 gallons to as low as 12.0 gallons in some models, actual driving range remained strong due to:

Efficiency Improvements

• Skyactiv-G high-compression engines
• Improved aerodynamics reducing drag
• Refined 6-speed transmissions delivering optimal cruising ratios
• Weight reduction strategies across platforms

As a result, modern Mazda 3 drivers enjoy fuel savings and similar or better range than older models with bigger tanks.

Detailed Breakdown of 2025 Mazda 3 Fuel Tank Capacity

Tank Sizes by Trim

For the 2025 Mazda 3, the following fuel-tank sizes apply:

12.7-Gallon Tank (AWD Turbo & AWD Non-Turbo)

• City range: ~292 miles
• Highway range: ~406 miles
• Combined: ~356 miles

13.2-Gallon Tank (FWD Trims)

• City range: ~356 miles
• Highway range: ~488 miles
• Combined: ~422 miles

Metric Equivalents

• 12.7 gallons ≈ 48.1 litres
• 13.2 gallons ≈ 50.0 litres

These metrics help international buyers and owners compare specs effectively.

Factors Influencing Real-World Range

Even with a precise tank capacity, real-world range varies due to:

Driving Style

• Hard acceleration increases consumption.
• Smooth throttle application extends range.

Traffic Conditions

• Stop-and-go city travel decreases efficiency.
• Constant-speed highway cruising provides optimal MPG.

Load & Terrain

• Added passenger or cargo weight reduces economy.
• Hilly terrain and headwinds increase fuel usage.

Temperature

• Cold climates reduce efficiency due to denser air and longer warm-up times.

For accurate planning, drivers should subtract ~10–20% from theoretical range figures.

Trim Differences & Why Tank Sizes Vary

Drivetrain Differences (FWD vs AWD)

AWD systems require additional mechanical components, often consuming underbody space, which can reduce fuel-tank size. This is why AWD turbo models typically receive the smaller 12.0–12.7 gallon tanks.

Engine Packaging

Turbocharged engines often require extra cooling hardware, influencing component layout around the tank.

Body Style Differences

Although most body styles share tanks, occasional hatchback vs sedan packaging differences do occur between generations.

Real-World Examples of Driving Range

Example 1: 13.2-Gallon Tank (FWD)

• Highway: ~488 miles
• You can effectively drive from London to Edinburgh (399 miles) without refueling.

Example 2: 12.7-Gallon Tank (AWD)

• Highway: ~406 miles
• Ideal for city-motorway blends, though slightly more frequent fuel stops.

Example 3: 12.0-Gallon Turbo Hatchback

• Highway: ~372 miles
• Still strong performance considering increased power output and AWD load.

Comparison With Compact-Car Rivals

Across the compact segment, most vehicles offer fuel tanks between 12 and 14 gallons. The Mazda 3 fits squarely within this category but often excels due to:

• Better real-world fuel efficiency
• Higher highway driving range
• More refined powertrain calibration

Older Mazda 3 models with 15.9-gallon tanks exceed the class average for capacity, giving them longer per-tank range than many rivals.

Key Mazda 3 Fuel-Tank Figures Summary
