24 MPG combined won’t win any hypermiling awards, but for the 2019 Mazda CX-9 2WD with its 2.5L 4-cylinder, it’s a practical compromise. This isn’t a vehicle bought by minimalists. It’s purchased by families who value driving dynamics and premium features as much as they need three rows of seating. These buyers understand fuel economy is a factor, but not the only one. They are accepting of this level of efficiency as a price to pay for the CX-9’s style, handling, and practicality.

City and highway performance

The EPA estimates suggest 22 MPG in the city and 28 MPG on the highway. These figures accurately reflect the CX-9’s character. Around town, the turbocharged 2.5L engine delivers ample torque for confident acceleration, but stop-and-go driving impacts fuel consumption. On the open road, the CX-9 settles into a relaxed cruise, allowing the engine to operate efficiently, getting you closer to that 28 MPG figure. The six-speed automatic transmission is well-matched to the engine’s power delivery, further helping highway fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mazda CX-9 2WD at exactly $1,800. This calculation is based on driving 15,000 miles per year, using EPA’s fuel economy estimates, and assuming current national average fuel prices. Individual spending may vary depending on driving habits and local fuel costs, but this figure represents a standardized benchmark for comparing fuel expenses across different vehicles. Families should consider this when budgeting for the cost of running a midsize SUV.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy varies. Aggressive driving, heavy loads, and consistently short trips will negatively impact MPG. Spending time on the highway can help you get closer to the EPA highway number. The key is understanding the CX-9’s engine. Its turbocharged nature means that efficiency suffers when you demand rapid acceleration.

Drive smoothly, anticipate traffic, and you will see your MPG climb. Some owners report exceeding the EPA combined figure with mindful driving habits.

How it compares

Compared to other three-row SUVs, the 2019 Mazda CX-9 2WD occupies a middle ground in fuel efficiency. The Ford Explorer with its base 2.3L EcoBoost engine achieves a comparable 24 MPG combined. The Toyota Highlander posts slightly better numbers at 24 MPG combined for its V6-powered, non-hybrid models, though it is not as engaging to drive. A Honda Pilot gets 23 MPG combined. These numbers highlight the tradeoffs buyers face: the CX-9’s refined driving experience comes at a minor cost in fuel economy compared to some of its rivals.

Tips to maximize efficiency

The Mazda CX-9 responds well to smooth driving. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. The turbocharged engine is sensitive to throttle inputs, so try to avoid dipping into the turbo’s boost range.

Keep your tires properly inflated. Check tire pressure regularly and maintain the pressure specified on the doorjamb sticker. Properly inflated tires reduce rolling resistance, improving fuel economy. A few PSI can make a difference, and it will also help lengthen the life of the tires.

Minimize idling. The CX-9, like all gasoline-powered vehicles, gets zero MPG while idling. If you anticipate being stopped for more than a minute or two, turn off the engine. This is important in city driving where you are most prone to traffic, accidents, and slowdowns.

Lighten the load. Remove unnecessary items from the CX-9. Extra weight increases fuel consumption, especially during acceleration and uphill climbs. Clear out any clutter and only carry essential items to help keep your fuel economy numbers up.

Service your CX-9 according to Mazda’s recommended maintenance schedule for optimal engine performance. This includes regular oil changes, air filter replacements, and spark plug maintenance, all of which contribute to efficient operation. These small costs will go a long way.
