The 2023 Mazda CX-9 4WD gets 23 MPG combined, a figure that reflects the CX-9’s design as a stylish, comfortable, and engaging three-row SUV. It prioritizes driving dynamics and a premium feel over maximum fuel savings. Mazda seems to understand its core buyers are families who value design and a touch of sportiness, and who are more interested in an enjoyable drive than hyper-efficient gas mileage.

City and highway performance

EPA estimates are 20 MPG in the city and 26 MPG on the highway for the 2023 Mazda CX-9 4WD. The city figure reflects the stop-and-go conditions where the CX-9’s turbocharger is frequently active, increasing fuel consumption. The CX-9’s weight and standard all-wheel drive contribute to this result. The highway number is more respectable; the CX-9 is more efficient on longer, steady-speed journeys where the engine can operate more efficiently.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mazda CX-9 4WD at $1,900. This is based on 15,000 miles of driving per year and average fuel prices. Individual fuel costs will vary based on local prices and driving habits, but this provides a standard comparison. Real-world highway MPG may increase or decrease this figure depending on your daily driving.

Real-world expectations

Expect some variance from the EPA estimates in real-world conditions. Aggressive driving, frequent short trips, and carrying a full load of passengers or cargo can decrease your average MPG. On the other hand, gentle acceleration, adhering to speed limits, and minimizing idling can improve your mileage. Drivers who prioritize smooth and predictable driving will experience better real-world results. It’s valuable to review CX 9 MPG across all years before buying.

How it compares

The 2023 Mazda CX-9’s fuel economy is in the middle range compared to other three-row SUVs with all-wheel drive. The Kia Telluride achieves a similar 21 MPG city/24 MPG highway/23 MPG combined. The Honda Pilot with AWD is rated at 19 MPG city/25 MPG highway/21 MPG combined. The Toyota Highlander Hybrid AWD is more efficient at 35 MPG combined, but has a higher price. If fuel economy is important, consider the Highlander Hybrid or front drive-only trims of models the CX-9 competes with. However, it is unlikely they will offer the same premium driving experience as the Mazda. See all Mazda fuel economy data to learn more.

Tips to maximize efficiency

Keep your tires properly inflated. Tire pressure affects rolling resistance, and underinflated tires decrease fuel economy. Check your tire pressure regularly and inflate them to the recommended PSI, found on a sticker inside the driver’s side door jamb.

Avoid aggressive acceleration and braking. The CX-9’s turbocharged engine responds to a light touch. Gradual acceleration will save fuel, and anticipating traffic and braking early avoids hard stops.

Minimize idling. Idling consumes fuel for no distance. If you’re stopped for more than a minute, turn off the engine. This applies in urban environments with frequent traffic lights.

Use cruise control on the highway. Cruise control keeps a consistent speed, optimizing fuel efficiency on long highway drives. It prevents unintentional speed changes that waste gas.
