The 2018 Mazda CX-3 2WD with its 2.0L engine gets 31 MPG combined, making it a reasonable choice for those who prioritize style and urban maneuverability over cargo space or off-road capability. This is a design-focused subcompact SUV aimed at young professionals, empty-nesters, or city dwellers who value a premium driving experience in a small package and accept slightly less fuel economy.

City and highway performance

The CX-3’s EPA ratings of 29 MPG in the city and 34 MPG on the highway show its intended use. The city figure is particularly relevant, as the CX-3 excels in urban environments. Its small size and responsive steering make it easy to navigate crowded streets and tight parking spots, where larger vehicles are less efficient. The 34 MPG highway rating is respectable, suggesting this CX-3 is a suitable commuter. The six-speed automatic transmission is well-matched to the engine, providing smooth shifts and maximizing efficiency at cruising speeds.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Mazda CX-3 2WD is $1,400. This figure is based on driving 15,000 miles per year and using the national average fuel price. The annual fuel cost can vary depending on individual driving habits, local fuel prices, and the type of fuel used. The EPA calculation uses regular unleaded fuel, which the CX-3 is designed to use. Driving more conservatively, opting for efficient tires, and keeping up with maintenance intervals can all help to reduce this expense.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary. Aggressive driving, frequent short trips, and carrying heavy loads can all decrease fuel efficiency. However, smooth acceleration, consistent speeds, and proper tire inflation can help drivers achieve or even exceed the EPA estimates. Understanding how driving habits impact fuel consumption is important for optimizing efficiency, as with any vehicle. Many owners report figures close to the EPA estimates, suggesting the CX-3’s fuel economy is reasonably predictable.

How it compares

The CX-3’s fuel economy is competitive in the subcompact SUV segment. The Honda HR-V 2WD achieves a slightly better 31 MPG combined, 28 city, and 34 highway. A Nissan Kicks fares even better, with 33 MPG combined, 31 city, and 36 highway. The CX-3 has a more upscale interior and a sportier driving feel than some rivals. Buyers often prioritize factors beyond just fuel efficiency. For those who are willing to sacrifice some driving fun, models like the Toyota C-HR offer similar fuel economy (29 MPG combined) with a more polarizing design.

Tips to maximize efficiency

Driving habits can enhance the Mazda CX-3’s fuel economy. Avoid rapid acceleration and hard braking whenever possible. Smooth, gradual acceleration will conserve fuel and reduce wear and tear on the vehicle’s components. Anticipate traffic flow and maintain a consistent speed to minimize unnecessary stops.

Tire pressure is important in fuel economy. Ensure your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, which reduces fuel efficiency. Regularly check and adjust tire pressure, especially during seasonal temperature changes.

Minimize the use of accessories that use a lot of energy from the engine. Air conditioning, particularly at full blast, consumes a significant amount of energy. Use it carefully, and consider opening windows or using the ventilation system when weather permits. Avoid leaving electronic devices charging unnecessarily when the engine is off.

Regular maintenance is important to optimizing fuel efficiency. Ensure the engine receives timely oil changes, air filter replacements, and spark plug maintenance. A well-maintained engine operates more efficiently, resulting in better fuel economy and lower emissions. Refer to the owner’s manual for the recommended maintenance schedule.

Consider the route that you are taking to get to your destination. If possible, routes that minimize stop and go traffic improve efficiency. Selecting routes that are direct and maintain a steady pace instead of constant acceleration and braking will drastically improve efficiency. You can find all Mazda fuel economy data on our site.
