The 2020 Mazda CX-3 2WD 2.0L achieves 31 MPG combined, which is impressive. It’s a subcompact crossover designed for urban agility and easy parking, not a hybrid, and not a particularly large or heavy SUV. That fuel economy rating makes it an appealing choice for city dwellers and first-time car owners who want good gas mileage without sacrificing style and a premium driving experience.

City and highway performance

The EPA estimates for the CX-3 are 29 MPG in the city and 34 MPG on the highway. The city figure is arguably more important for this vehicle, as CX-3 drivers are more likely to spend time navigating congested urban environments than embarking on cross-country road trips. The CX-3’s small size and responsive steering make it a natural fit for city driving, and its fuel efficiency in these conditions makes it an even more attractive option. However, the 34 MPG highway figure shouldn’t be overlooked. It provides valuable fuel savings on longer journeys and makes the CX-3 a surprisingly capable long-distance commuter.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mazda CX-3 2WD 2.0L at $1,400. This calculation is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using national average fuel prices. Keep in mind that fluctuating gas prices and your individual driving habits can cause considerable variation in this figure. The key takeaway is that the CX-3 is relatively cheap to fuel compared to larger SUVs or vehicles with less efficient engines. Consider this figure a baseline as you explore all Mazda fuel economy data.

Real-world expectations

While the EPA’s estimates provide a useful benchmark, real-world fuel economy can vary. The CX-3’s 2.0L engine responds well to a light foot, and drivers who prioritize smooth acceleration and consistent speeds are likely to achieve figures close to the EPA estimates. Conversely, aggressive driving, frequent hard acceleration, and consistent use of air conditioning can negatively affect fuel economy. Expect lower MPG if you frequently drive in hilly or mountainous areas, since topography also plays a role. Always consider your own driving style and typical driving conditions when assessing whether the CX-3’s fuel economy aligns with your expectations. The actual MPG you achieve will also vary with maintenance, so keeping up with scheduled items goes a long way toward preserving economy.

How it compares

The CX-3 competes in a crowded subcompact SUV segment with several fuel-efficient alternatives. The Nissan Kicks, for example, boasts 31 MPG in the city and 36 MPG on the highway, making it a slightly more fuel-efficient option overall. The Honda HR-V, another popular competitor, achieves 28 MPG in the city and 34 MPG on the highway with its standard 2WD configuration. While the CX-3’s fuel economy is competitive, these alternatives offer similar or, in some cases, slightly better fuel economy. However, the Mazda prioritizes driving enjoyment and an upscale interior, so the decision often comes down to individual priorities rather than outright fuel efficiency. If you care most about fuel efficiency alone, there are better choices. If you want driving enjoyment with good, though not class-leading, MPG, then the CX-3 makes a strong case for itself. Owners should also cross-shop to similar models like the Toyota C-HR and Kia Niro (hybrid), and compare those vehicles with the CX 3 MPG across all years.

Tips to maximize efficiency

The CX-3’s engine responds well to gradual acceleration. Avoid flooring the accelerator whenever possible, as this dramatically increases fuel consumption. Instead, aim for smooth and progressive acceleration to maintain optimal efficiency. Anticipate traffic flow and try to maintain a consistent speed whenever possible. Frequent braking and acceleration waste fuel.

Proper tire inflation is critical for maximizing fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Use a reliable tire pressure gauge to ensure accurate readings.

Unnecessary weight in the vehicle can negatively impact fuel economy. Remove any items you don’t need from the trunk or passenger area to reduce the load on the engine. Every extra pound adds up.

Scheduled maintenance is essential for maintaining optimal fuel economy. Regular oil changes, air filter replacements, and tune-ups ensure that the engine is running efficiently. Follow the recommended maintenance schedule in your owner’s manual.

Consider using the CX-3’s Sport mode sparingly. While it enhances the driving experience by providing sharper throttle response and more aggressive shift points, it also consumes more fuel. Use it only when you need extra power or responsiveness, otherwise, stick to the standard driving mode for optimal efficiency.
