23 MPG combined doesn’t exactly scream “fuel sipper,” but for the 2020 Mazda CX-9 4WD, it’s a calculated compromise. This isn’t a vehicle for hypermilers; it’s engineered for drivers who need three rows of seating, appreciate a touch of luxury, and value responsive handling more than saving every last mile per gallon. The CX-9 attracts those who want a family SUV that doesn’t feel like a penalty box behind the wheel, and they’re typically willing to accept slightly lower fuel economy in exchange for the driving experience Mazda delivers.

City and highway performance

The EPA estimates for the 2020 CX-9 4WD place city driving at 20 MPG and highway cruising at 26 MPG. The slightly lower city MPG is typical for larger vehicles, as stop-and-go traffic and idling reduce efficiency. This makes sense, since the typical CX-9 buyer will often be navigating urban landscapes loaded with kids and cargo, or sitting idle while waiting in the school pickup lane. The 26 MPG highway figure is respectable, illustrating the engine’s efficiency when maintaining a consistent speed. While 26 MPG isn’t groundbreaking, it’s sufficient to make highway road trips feasible without constant fuel stops.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mazda CX-9 4WD at $1,900. This figure is based on driving 15,000 miles per year, with a specific ratio of city to highway driving, using the national average fuel prices at the time of calculation. It’s a useful benchmark for comparing running costs with other vehicles. Your actual fuel costs may deviate based on your individual driving habits, the type of fuel you buy, and the specific prices in your geographic location.

Real-world expectations

EPA estimates are a starting point, but real-world MPG can vary significantly. Factors such as driving style, traffic conditions, terrain, and even tire pressure will affect your fuel consumption. Drivers with a heavy foot will undoubtedly see numbers closer to the city estimate, while those who prioritize smooth acceleration and consistent speeds could potentially exceed the highway figure. Regular maintenance, including timely oil changes and air filter replacements, is crucial for maintaining optimal fuel efficiency. Don’t expect to hit the EPA numbers if you regularly haul heavy loads or live in an area with steep hills.

How it compares

Compared to its competitors in the three-row SUV segment, the CX-9’s fuel economy is mid-pack. For example, the Honda Pilot with all-wheel drive often sees combined MPGs in the 22-24 range, aligning closely with the CX-9. The Toyota Highlander Hybrid, on the other hand, delivers significantly better economy at around 35 MPG combined, but comes at a higher price point and with a different driving experience. The Ford Explorer with its base engine achieves similar numbers to the CX-9. Consider all Mazda fuel economy data to weigh the tradeoffs in price and performance. Buyers who prioritize fuel efficiency above all else might gravitate towards the Highlander Hybrid, but those seeking a more engaging driving experience with similar fuel costs may prefer the CX-9. You can also check fuel economy numbers for all years of the CX 9 MPG across all years.

Tips to maximize efficiency

Use the CX-9’s “Sport” mode only when needed for merging or passing. While it enhances responsiveness, it also lowers fuel economy. During normal driving, keep the vehicle in the standard drive mode for optimal fuel consumption. The transmission will shift more conservatively, preserving fuel.

Regularly check and maintain the correct tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure for your CX-9.

Avoid aggressive acceleration and braking. Practice smooth and progressive throttle control to minimize fuel waste. Anticipate traffic flow and maintain a safe following distance to reduce the need for sudden stops.

Reduce unnecessary weight in the vehicle. The heavier the vehicle, the more fuel it consumes. Remove any items from the cargo area that are not essential. This is especially important for urban drivers often hauling cargo.
