24 MPG combined isn’t going to win any hypermiling awards, but for the 2017 Mazda CX-9 2WD 2.5L 4-cyl, it’s a calculated compromise. This isn’t a fuel-sipping hybrid; it’s a stylish, family-oriented SUV designed for drivers who value performance and driving dynamics over absolute fuel efficiency. The target customer knows that moving a vehicle this size requires fuel, and they’re willing to accept a slightly lower MPG in exchange for Mazda’s driving experience and premium interior.

City and highway performance

The EPA estimates the 2017 CX-9 2WD at 22 MPG in the city and 28 MPG on the highway. The city rating reflects stop-and-go traffic, where the CX-9’s weight and automatic transmission (S6) demand more fuel. The highway number is respectable, showcasing the engine’s ability to maintain reasonable efficiency at cruising speeds. Mazda’s Skyactiv technology prioritizes lightweight construction and efficient engine design. These EPA numbers were achieved in standardized testing conditions. The 2.5L turbocharged engine, while not a hybrid, is engineered to deliver a balance of power and efficiency, and these numbers reflect that compromise.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Mazda CX-9 2WD 2.5L 4-cyl to be $1,800. This is calculated based on driving 15,000 miles per year, using the national average fuel price at the time of testing. This is just an estimate, and your actual fuel costs will vary depending on your driving habits, city versus highway driving, and local fuel prices. Aggressive driving, frequent short trips, and consistently paying top dollar at the pump will all inflate your annual fuel bill.

Real-world expectations

While the EPA numbers provide a useful benchmark, real-world driving often differs. CX-9 owners often report figures that are plus or minus a few MPG from the EPA estimates. Weather, tire pressure, and cargo weight all contribute to variations in fuel consumption. Regular maintenance, including oil changes and air filter replacements, also plays a role in achieving optimal fuel efficiency. Don’t be surprised if your actual MPG differs from the sticker; instead, focus on driving habits and maintenance to maximize your fuel economy.

How it compares

The 2017 CX-9’s fuel efficiency sits in a competitive spot within the midsize SUV segment. The Toyota Highlander LE with its 2.7L 4-cylinder engine manages approximately 20 MPG city and 24 MPG highway, making the CX-9 a more efficient choice. The Ford Explorer with its base 2.3L EcoBoost engine achieves around 19 MPG city and 27 MPG highway, demonstrating that efficiency is available but only with a smaller engine. The Honda Pilot, another popular choice, gets around 20 MPG city and 27 MPG highway in its base LX trim. The CX-9’s slightly better MPG, especially in the city, further justifies its powertrain choice. For someone seeking more information, see CX 9 MPG across all years.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The CX-9’s turbocharged engine responds readily to throttle inputs, but that responsiveness comes at the cost of fuel economy. A more measured approach to acceleration and anticipating traffic flow will reduce fuel consumption significantly, especially in urban environments. Maintain consistent momentum and minimize unnecessary braking whenever possible.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, ideally every few weeks, and inflate them to the recommended pressure listed on the sticker inside the driver’s side door jamb. A simple tire pressure gauge can save you money at the pump over time.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, reducing throttle variations and improving fuel efficiency on long highway drives. Cruise control is most effective on relatively flat terrain; on hilly roads, it may downshift frequently, negating some of the fuel-saving benefits. For all Mazda models, you can check all Mazda fuel economy data.

Lighten your load. Carrying unnecessary weight in your CX-9 impacts fuel economy. Remove any items from the trunk or cargo area that you don’t need on a regular basis. Extra weight forces the engine to work harder, resulting in increased fuel consumption. Emptying out unnecessary items is a free and easy way to improve your MPG.

Consider using the CX-9’s “Sport” mode sparingly. Sport mode enhances throttle response and shift points, but it also keeps the engine revving higher, decreasing fuel efficiency. Reserve Sport mode for situations where you need extra performance, such as merging onto the highway, and switch back to normal mode for everyday driving.
