The 2019 Mazda CX-3 4WD 2.0L’s 29 MPG combined fuel economy won’t break any records, but it’s respectable and fits the car’s purpose. The CX-3 isn’t trying to compete with a Prius or a large, fuel-efficient SUV. It’s a stylish, urban-friendly vehicle that offers a premium feel and all-weather capability in a small package that’s easy to park. Buyers attracted to its sharp design and nimble handling are likely willing to accept slightly above-average fuel costs for its unique charm and driving experience.

City and highway performance

The EPA estimates for the 2019 CX-3 4WD are 27 MPG in the city and 32 MPG on the highway. These numbers show where the CX-3 performs well and where it could be better. The 2.0L engine has enough power for city driving, allowing it to keep up with traffic without needing too much throttle. The six-speed automatic transmission helps optimize fuel efficiency at lower speeds. On the highway, the CX-3 can easily maintain speed, but the smaller engine has to work harder, slightly affecting fuel efficiency. The difference between city and highway MPG is smaller than in some other vehicles, suggesting that the CX-3’s engine and transmission work well in different driving conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mazda CX-3 4WD at $1,500. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate. Your actual fuel costs will change depending on how you drive, local fuel prices, and the type of fuel you use. If you drive fewer miles or live where fuel is cheaper, your costs will be lower. But if you drive more aggressively or live where fuel is more expensive, expect to spend more than $1,500.

Real-world expectations

The EPA estimates are a good starting point, but real-world fuel economy can be quite different. Aggressive driving, stop-and-go traffic, cold weather, and even tire pressure can all impact MPG. CX-3 owners often report numbers a bit lower than the EPA estimates, especially in mixed driving. However, many drivers who accelerate gently and anticipate traffic can get numbers close to or even slightly better than the official ratings. Regular maintenance, especially keeping tires properly inflated and changing oil on time, is also critical for getting the best fuel efficiency.

How it compares

The 2019 CX-3’s fuel economy is competitive in the subcompact crossover segment and beats smaller SUVs with more powerful engines. For example, the all-wheel-drive Honda HR-V also gets 29 MPG combined. The Nissan Kicks, which doesn’t offer all-wheel drive, gets a better combined rating of 33 MPG. Buyers often compare these vehicles based on styling, features, and driving, considering fuel economy as one factor. The CX-3 stands out with its more upscale interior and engaging driving experience, which some buyers value more than the best possible fuel efficiency. You can view all Mazda fuel economy data to compare the CX-3 across the manufacturer’s full lineup.

Tips to maximize efficiency

Accelerate and brake smoothly. The CX-3’s engine responds quickly, which can lead to spirited driving, but easing off the gas and avoiding sudden stops will greatly improve fuel economy. Give yourself plenty of time to slow down by watching traffic, and avoid accelerating quickly for no reason.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which makes the engine work harder and lowers fuel economy. Check your tire pressure regularly, at least once a month, and inflate them to the pressures shown on the sticker on the driver’s side doorjamb.

Minimize idling. Idling wastes fuel without going anywhere. If you’re stopped for more than a minute or two, it’s usually better to turn off the engine. This is especially important in cities where frequent stops are common.

Reduce weight in the vehicle. Carrying extra cargo, like sports gear or tools, increases the vehicle’s weight and lowers fuel economy. Take out any unnecessary items from the trunk and passenger area to reduce the load.

Consider limiting air conditioning use, especially when the weather is mild. Air conditioning puts extra strain on the engine, reducing fuel efficiency. On cooler days, opening the windows or using the ventilation system can be a more fuel-efficient choice until it gets too hot for those methods to effectively cool the cabin.
