26 MPG combined is a strong figure for the 2026 Mazda CX-90 4WD 2.5L 4-cyl, particularly for a premium, family-oriented three-row SUV. Mazda’s meticulous engineering delivers efficiency in a package that prioritizes driving dynamics, design, and ample interior space. Buyers attracted to this CX-90 variant appreciate Mazda’s ‘Kodo’ design philosophy and driver-centric approach, but also demand sensible running costs in their daily hauler. They might be upgrading from a smaller SUV, or perhaps downsizing from a larger, thirstier model, seeking a refined driving experience without the fuel price penalty often associated with vehicles of this size and capability. This 26 MPG is a sweet spot, providing enough efficiency to make long commutes palatable while still retaining the power and composure expected from a flagship SUV.

City and highway performance

The EPA rates the 2026 Mazda CX-90 4WD 2.5L 4-cyl at 24 MPG in the city and 28 MPG on the highway. This spread reflects the vehicle’s design philosophy. The lower city figure for a 2.5L four-cylinder might raise an eyebrow for some, but the CX-90’s curb weight and standard all-wheel-drive system both exact a toll in stop-and-go traffic. Mazda’s automatic (S8) transmission is calibrated for smooth, predictable shifts, prioritizing refinement over an aggressive, economy-focused mapping that might detract from the driving experience. The 28 MPG highway figure is particularly noteworthy. It demonstrates the engine’s ability to operate efficiently at cruising speeds, where the vehicle’s aerodynamic profile and the transmission’s higher gear ratios can truly shine. These numbers resonate with families who frequently embark on weekend trips or longer journeys, where the bulk of their driving is done on open roads. For them, the highway efficiency translates directly into fewer fuel stops and smoother travel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2026 Mazda CX-90 4WD 2.5L 4-cyl at $2,250. This figure is based on an assumed 15,000 miles of driving per year, split evenly between city and highway driving, and using national average fuel prices. It provides a standardized benchmark for consumers to understand the long-term running costs associated with vehicle ownership. For the CX-90 buyer, this $2,250 figure is a significant factor in their decision. They are likely a consumer who balances initial purchase price with ongoing expenses. A three-row SUV like the CX-90 is a substantial investment, and understanding that annual fuel outlay upfront helps solidify the value. This cost places the CX-90 squarely in the realm of family-friendly vehicles with manageable operating expenses, avoiding the higher fuel bills often associated with larger, more powerful V6 or V8 SUVs. The transparency of this estimate helps buyers budget effectively and reinforces the CX-90’s appeal as a practical yet reliable choice.

Real-world expectations

While EPA estimates provide a valuable baseline, real-world fuel economy for the 2026 Mazda CX-90 4WD 2.5L 4-cyl typically mirrors these figures closely, given Mazda’s conservative approach to calibration. Owners consistently report mileage within 1-2 MPG of the official estimates. The efficiency of this vehicle, particularly in the urban cycle, is heavily influenced by driving style. Aggressive acceleration and frequent hard braking will push the city MPG closer to the lower end of the spectrum. Conversely, a smooth, measured driving approach will allow drivers to consistently hit or even slightly exceed the 24 MPG city rating. Highway driving is where the CX-90 often impresses, with many drivers easily achieving 28 MPG or more, especially when maintaining a steady speed in the mid-60s MPH range. For those considering a CX-90, understanding that proactive driving habits directly translate into better fuel economy is key. This isn’t a vehicle that demands constant attention to eke out efficiency, but rather rewards a composed driving style with consistent results.

How it compares

The 2026 Mazda CX-90 4WD 2.5L 4-cyl positions itself against its competitors in the crowded three-row SUV segment. Its 26 MPG combined rating puts it ahead of many direct rivals, especially those that rely on naturally aspirated V6 engines. The Honda Pilot FWD, for instance, typically nets 22 MPG combined (19 city/27 highway), and the Subaru Ascent comes in at 22 MPG combined (20 city/26 highway). Even the Hyundai Palisade FWD, often praised for value, manages 22 MPG combined (19 city/26 highway). The CX-90 stands out in its blend of efficiency and premium feel. Its driving dynamics and interior materials often draw comparisons to entry-level luxury SUVs. Consider the Acura MDX FWD, which offers 22 MPG combined (19 city/26 highway), or even the Lexus RX L (non-hybrid), at around 21 MPG combined. The CX-90’s 2.5L 4-cylinder engine, while not offering the raw power of a larger V6, delivers adequate performance for most situations, especially when paired with its refined automatic gearbox. Its efficiency makes it an attractive choice for buyers who want the benefits of a premium SUV but are not willing to compromise on fuel economy. For those who prioritize efficiency, Mazda also offers the CX-90 with more powerful hybrid and PHEV powertrains, but the 2.5L remains a strong offering.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the easiest and most impactful ways to ensure your CX-90 is running as efficiently as possible. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, at least once a month, and ensure they are inflated to the manufacturer’s recommended levels.

Adopting a smooth, anticipatory driving style will significantly improve your real-world MPG in the CX-90. Avoid rapid acceleration and hard braking, instead, look ahead, anticipate traffic flow, and allow the vehicle to coast when appropriate. The CX-90’s well-tuned chassis and transmission reward this kind of driving, enhancing both comfort and economy.

Minimizing unnecessary weight in the vehicle can also contribute to better fuel economy. While the CX-90 is designed for families, removing heavy items that are not routinely needed can reduce the burden on the engine, especially during acceleration. Regularly clear out the cargo area and passenger cabin of extraneous gear.

Routine maintenance, particularly adhering to the manufacturer’s recommended service intervals for oil changes and air filter replacements, is crucial for optimal engine operation. A well-maintained engine runs more efficiently, ensuring that the 2.5L four-cylinder in your CX-90 performs its best without consuming more fuel than necessary.
