Why is the Mazda CX-4 fuel tank small?

[DiAngela]

Mazda CX-4 has a 45L fuel tank, and the reason for the small tank is to allow for modification to a dual-tank system. Definition of automotive fuel tank: The automotive fuel tank is the full name of the car fuel tank. Currently, with the development of the automotive industry and the revitalization of the domestic automobile industry, the demand for automotive fuel tanks from major automobile manufacturers has shown a clear upward trend. Design principle of automotive fuel tank: Utilizing the heat energy generated by the engine during vehicle operation, a thermal circulation system is added between the engine, fuel tank, and radiator. The original single fuel tank is designed into a combined fuel tank consisting of a main tank and an auxiliary tank.

I've recently researched Mazda's vehicles, and the CX-4's smaller fuel tank is primarily for sporty performance. Mazda has always emphasized the 'Jinba Ittai' driving feel, where a lighter car enhances steering agility. Reducing the fuel tank from the standard SUV's 60 liters to 45 liters sheds dozens of pounds, significantly easing the chassis burden during cornering. Combined with their Skyactiv engine's fuel efficiency, a full tank can easily cover 500 kilometers for city commuting. While highway driving may require more frequent refueling, this is a trade-off for superior handling—after all, CX-4 drivers are more about enjoying the thrill of driving than long-distance travel.

As a CX-4 owner, I believe the small fuel tank is inseparable from its design philosophy. This car isn't a pure family SUV - the fastback styling makes the rear space compact, forcing the fuel tank to adopt a flat structure. I've compared it with the CR-V in the same price range, whose boxy body can accommodate a 57-liter tank. But Mazda chose to preserve the coupe's aesthetic appeal at the cost of some fuel capacity. Fortunately, with urban fuel consumption at just 7-8 liters, it's sufficient for commuting. The manufacturer probably also considered today's dense gas station network, making the small tank's disadvantage less noticeable in cities.

The positioning of the Mazda CX-4 is quite unique within the Mazda lineup, and its small fuel tank actually reflects its target user base. Compared to family-oriented models like the CX-5, the CX-4 is more tailored towards younger demographics and urban commuting needs. Think about it—how much fuel do you really use for daily commutes? A 45-liter fuel tank is more than enough to cover two weeks of commuting. On the contrary, a larger tank would add weight, increase fuel consumption, and make the car feel more cumbersome when parking. I’ve driven a friend’s CX-4, and its light and agile steering wheel is a testament to its lightweight design, which is also evident in its compact fuel tank.

From a technical perspective, the CX-4's chassis layout limits fuel tank capacity. Its multi-link rear suspension design requires more space for the exhaust pipe and muffler than typical SUVs. To maintain chassis flatness, the fuel tank had to sacrifice thickness. With a 2700mm wheelbase, the large wheel arches and rear driveshaft area further restrict available width for the fuel tank. Mazda engineers prioritized ground clearance and suspension tuning - the true essence of an SUV. After all, more frequent refueling beats a bumpy ride any day.

When researching Mazda, I noticed they place special emphasis on weight distribution. The CX-4 positions its fuel tank in front of the rear axle, which helps balance front-rear weight distribution and reduces body roll during cornering. If the 60-liter fuel tank were placed under the trunk like in some other vehicles, the center of gravity would shift noticeably during turns. Although the current design has a smaller fuel capacity, it provides more stable handling. During my test drive, I specifically observed this point - the body barely swayed during quick lane changes. Plus, with the fuel-saving automatic start-stop system, the actual range isn't much shorter than vehicles with larger tanks. Just fill up before highway driving.
