The 2022 Mazda CX-30 4WD with the 2.5L engine gets 26 MPG combined. That’s a calculated trade-off: it’s not the most efficient in its class, but Mazda is prioritizing engaging driving and stylish design over winning economy awards. This crossover appeals to buyers who value aesthetics and road feel along with saving money at the pump. CX-30 buyers want character more than extreme frugality.

City and highway performance

The EPA estimates 24 MPG in the city and 31 MPG on the highway. The city figure reflects the CX-30’s responsive throttle and relatively light weight, which lets it move through traffic confidently. The highway number is respectable, though some drivers might wish it were higher. All-wheel drive gives the CX-30 more capability in winter weather, but it also lowers fuel economy slightly. Drivers who spend lots of time on highway commutes will notice the difference compared to front-wheel-drive models. But the willing 2.5L engine never feels strained, even at higher speeds, which reduces fuel consumption concerns on longer trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mazda CX-30 4WD 2.5L is $1,700. This is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices change, and everyone drives differently, so this is just a baseline for comparison. Someone who drives more than 15,000 miles a year or does more city driving will spend more. If you drive less and stay on the highway, you may spend less. Consider this the starting point when budgeting for ownership costs.

Real-world expectations

EPA estimates are a standard, but real-world MPG often varies. The CX-30’s official numbers are generally achievable. Aggressive driving, enjoying that responsive throttle too much, can easily drop the MPG below 26 combined. Careful drivers who accelerate smoothly and maintain consistent speeds can see numbers close to, or even slightly above, the EPA estimates. Cold weather affects all vehicles, so it can temporarily reduce fuel economy. The best way to learn about real-world MPG for this CX-30 is to check owner forums and online fuel tracking apps. They collect data from many drivers in different climates and conditions.

How it compares

The CX-30 4WD’s fuel economy is average for a subcompact crossover. The similarly equipped Subaru Crosstrek with standard all-wheel drive gets around 27 MPG combined, slightly better. The Honda HR-V (pre-2023 redesign) with all-wheel drive gets about 28 MPG combined. Other competitors like the Nissan Kicks with front-wheel drive can reach 31 MPG combined, but it doesn’t have all-wheel drive or the CX-30’s driving experience. The all-wheel-drive Kia Seltos, with its optional turbo engine, gets around 27 MPG combined, close to the CX-30. CX-30 buyers aren’t only trying to maximize MPG, they will trade some miles per gallon for Mazda’s driving dynamics and upscale interior. Consider all Mazda fuel economy data when you shop.

Tips to maximize efficiency

Tire pressure is often overlooked, but it affects fuel economy. Regularly check and maintain the recommended tire pressure using the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder and burn more fuel. Properly inflated tires are a simple, free way to improve your CX 30 MPG across all years.

Gentle acceleration and smooth braking are important to optimizing fuel efficiency. Avoid sudden bursts of speed and hard braking, which waste fuel and strain the engine and brakes. Predict traffic flow and maintain a consistent speed when you can. The CX-30’s responsive engine can be tempting, but modulating the throttle will give you better fuel savings.

Keep idling time to a minimum. If you’re going to be stopped for more than a minute, turn off the engine. Idling uses fuel without going anywhere. This matters in cities with lots of red lights and stop-and-go traffic. The CX-30 doesn’t automatically stop and start the engine, but turning it off manually will help with your daily fuel consumption.

Carry less weight in the vehicle. Extra cargo adds weight, making the engine work harder and use more fuel. Remove items you don’t need regularly from the trunk and passenger area. It all helps, especially in a smaller vehicle like the CX-30.

On the highway, use cruise control when you can. It helps maintain a consistent speed, which minimizes fuel consumption changes. Don’t use cruise control in hilly areas, because this can make the system downshift aggressively to maintain speed, which wastes fuel.
