29 MPG combined gives the 2020 Mazda CX-3 4WD 2.0L a respectable fuel economy rating, especially when you consider its purpose. This isn’t a stripped-down economy car; it’s a stylish, premium-feeling subcompact crossover designed to deliver an engaging driving experience in all weather conditions. For its target buyer, often a young professional or urban dweller prioritizing maneuverability and a touch of luxury over sheer cargo volume, fuel efficiency is a consideration, but not always the most important one.

City and highway performance

The EPA estimates 27 MPG in the city and 32 MPG on the highway for the 2020 Mazda CX-3 4WD. The city figure reflects the realities of stop-and-go traffic, where all-wheel-drive systems tend to reduce efficiency, as does the CX-3’s responsive but not overly thrifty 2.0-liter engine. The highway number is more promising, showcasing the benefit of the CX-3’s well-tuned automatic transmission and relatively light curb weight. Long road trips will yield better fuel economy than daily commutes snarled in urban congestion.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2020 Mazda CX-3 4WD 2.0L is $1,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that your actual fuel costs may vary depending on several factors, including your driving habits, the type of fuel you use (although the CX-3 does not require premium fuel), and where you live, as fuel prices can vary substantially from state to state and even city to city.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy can differ. Some drivers report achieving figures close to the EPA estimates, but aggressive driving, extended idling, and carrying extra weight can all negatively impact fuel efficiency. If you drive carefully and perform consistent maintenance you can help you achieve or even exceed the EPA numbers. Check driver forums to see what other 2020 CX-3 owners are experiencing in terms of fuel economy.

How it compares

Compared to its competitors, the 2020 Mazda CX-3 4WD holds its own in terms of fuel economy. For example, the Honda HR-V AWD achieves around 28 MPG combined, slightly less than the Mazda. A Jeep Renegade 4×4 with the 2.4L engine gets close to 24 MPG combined, a notable drop compared to the CX-3 because of its boxier shape and heavier components. Even the Subaru Crosstrek, known for its standard all-wheel-drive system and reputation for efficiency, sits right around 29 MPG combined matching the CX-3. These comparisons matter to CX-3 buyers, who want practicality but don’t want to sacrifice style or driving pleasure for ultimate fuel savings.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Mazda CX-3 rewards smooth driving. Anticipate traffic flow and maintain a steady speed whenever possible to keep the engine operating in its most efficient range. Jackrabbit starts and hard stops are fuel economy killers, so slow down for corners and avoid tailgating.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and consumes more fuel. Check your tire pressure regularly using a reliable gauge, and inflate them to the pressure recommended on the sticker located on the driver’s side doorjamb.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. If you expect to idle for more than a minute or two, turn off the engine to save gas. This is particularly important in cold weather, where extended warm-up times can significantly reduce fuel economy. All Mazda fuel economy data is published and up-to-date right here.

Reduce unnecessary weight. Carrying extra weight in your vehicle, whether it’s cargo or passengers, increases the amount of energy required to accelerate and maintain speed. Remove any items you don’t need from the cargo area and passenger compartment to improve fuel efficiency.

Maintain your vehicle properly. Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, ensures that your engine is running optimally. A poorly maintained engine is less efficient and consumes more fuel. The CX 3 MPG across all years is well documented and easily found.
