The 2020 Mazda CX-30 4WD, with the 2.5L 4-cylinder engine, gets 26 MPG combined. It’s not going to win any hypermiling contests, but that’s a reasonably efficient number for a stylish, compact crossover that’s fun to drive and has all-wheel drive. The CX-30 isn’t for those solely focused on maximum fuel savings; it’s for people who want some fun and practicality in a small package and are willing to accept slightly average fuel consumption.
City and highway performance
The EPA estimates the 2020 CX-30 4WD gets 24 MPG in the city and 31 MPG on the highway. This reflects the engine’s tuning for quick acceleration and the all-wheel-drive system’s slight inherent efficiency loss. The city MPG is fine for navigating cities, while the highway MPG makes longer road trips tolerable. Owners shouldn’t expect major swings in either direction under normal driving. Expect consistent performance within the EPA estimate.
Annual fuel cost
The EPA calculates the annual fuel cost for the 2020 Mazda CX-30 4WD at $1,700 per year. This is based on driving 15,000 miles annually and using national average fuel prices. The real cost will vary depending on driving habits, local fuel prices, and gasoline grade. The $1,700 figure offers a standard for comparing the running costs against other choices. If local fuel prices are higher than the national average, or if you drive more than 15,000 miles per year, the actual cost will be higher.
Real-world expectations
While the EPA estimates provide a consistent comparison, real-world fuel economy will vary depending on several things. Hard acceleration, frequent short trips, and heavy loads can all hurt fuel efficiency. On the other hand, smooth acceleration, consistent speeds, and proper tire inflation can get you better mileage. Because the CX-30 2.5L has a small engine and the vehicle is on the heavier side, it’s prone to suffering during slow, stop-and-go driving. Drivers who spend most of their time on the highway, and who accelerate gently, are likely to get close to the EPA’s 31 MPG estimate. See CX 30 MPG across all years for comparison.
How it compares
The 2020 Mazda CX-30 2.5L 4WD’s fuel economy is in the middle compared to other small crossovers with all-wheel drive. For example, the Subaru Crosstrek gets slightly better fuel economy, with an EPA rating of 29 MPG combined for its base engine with CVT transmission and the Honda HR-V, another popular choice, gets about 28 MPG combined. The Nissan Kicks gets nearly 33 MPG combined, making it much more fuel efficient, though it’s only offered in front-wheel drive. However, those vehicles often aren’t as fun to drive or don’t have as nice an interior, areas where the CX-30 excels. Think about what’s important to the buyer. If saving gas is the only concern, other options exist. The CX-30 balances economy with a premium feel and fun driving, which many buyers find more compelling than a few extra miles on the gallon.

Tips to maximize efficiency
Smooth acceleration is important to getting the best gas mileage in the CX-30. The 2.5L engine responds well to gentle acceleration, meaning you don’t have to rev the engine too much, which wastes gas. Treat every stoplight like an egg under your pedal.
Proper tire inflation is another simple way to improve fuel efficiency. Check your tire pressure regularly and inflate them to what’s recommended on the tire placard. Underinflated tires increase rolling resistance, which lowers fuel economy and can also wear out your tires faster.
Reduce extra weight in the vehicle. Carrying extra cargo makes the engine work harder and reduces gas mileage. Remove items you don’t need regularly, such as sports equipment or extra supplies.
Minimize idling. Idling wastes fuel. If you’re stopped for more than a minute, it’s usually better to turn off the engine and restart it when you’re ready to go, especially in modern vehicles with efficient starting systems.
Plan routes to avoid stop-and-go traffic and crowded areas, especially during rush hour. Maintaining speed on open roads uses much less gas than navigating city streets with frequent stops.
