25 MPG combined isn’t going to win any hypermiling competitions, but it’s a respectable figure for the 2024 Mazda CX-90 4WD with the 2.5L four-cylinder engine. This isn’t a compact crossover designed for maximum efficiency. It’s a three-row SUV aimed at families who prioritize driving dynamics, interior quality, and distinctive styling over ultimate fuel savings. The CX-90 buyer appreciates the finer things and needs the space, but isn’t willing to sacrifice a connected driving experience.

City and highway performance

The EPA estimates for city and highway driving are surprisingly close: 24 MPG in the city and 27 MPG on the highway. This tight range suggests that the CX-90’s engine and eight-speed automatic transmission are well-matched for a variety of driving conditions. You won’t see a dramatic drop in fuel economy navigating stop-and-go traffic, nor will you experience a huge surge on long highway cruises. The consistency indicates a well-tuned engine management system and efficient gearing.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Mazda CX-90 4WD 2.5L is $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that your actual fuel costs will vary depending on your driving habits, local fuel prices, and the specific conditions in which you drive. If you primarily drive in heavy traffic or have a lead foot, you can expect to spend more. Conversely, if you do a lot of highway driving and practice fuel-efficient driving techniques, you may be able to beat the EPA estimate. Compare this to all Mazda fuel economy data to understand where it fits in the lineup.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Factors such as weather, road conditions, driving style, and even tire pressure can impact your MPG. Expect to see numbers similar to the EPA estimates with a mindful driving style. Aggressive acceleration and frequent braking will naturally reduce your fuel economy. If you frequently carry passengers or cargo over steep terrain, expect your average to skew lower than the EPA’s estimates. Don’t forget to check CX 90 MPG across all years to compare this year’s model with older versions.

How it compares

The Mazda CX-90 competes in a crowded segment with a wide range of fuel economy figures. The Toyota Highlander, with its hybrid variants, achieves significantly better mileage than the CX-90 particularly in the city. Some Highlander hybrid models can easily exceed 35 MPG combined. The Kia Telluride, another popular three-row SUV, delivers combined figures in the low 20s, similar to the CX-90. The Honda Pilot, especially in its all-wheel-drive configuration, also hovers around the same MPG figures. Finally, the Ford Explorer, depending on the engine and trim, offers a mix of fuel economy, ranging from the low 20s to the mid-20s and a hybrid option. All of these competitors are worth comparing carefully before deciding on which vehicle to purchase.

Tips to maximize efficiency

Gentle acceleration and smooth braking are universally effective ways to improve fuel economy. Avoid jackrabbit starts and anticipate traffic flow to minimize hard braking. This strategy allows the CX-90’s engine and transmission to operate more efficiently, reducing fuel consumption in city driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels found on the sticker inside your driver’s side door. Proper inflation also extends tire life and improves handling.

Reduce unnecessary weight. Carrying heavy cargo in the CX-90’s cargo area or roof rack increases the vehicle’s overall weight, diminishing fuel economy. Remove any items you don’t need to lighten the load and improve efficiency. This is particularly relevant if you only occasionally need the third-row seats.

Use cruise control on the highway. Maintaining a consistent speed with cruise control minimizes unnecessary acceleration and deceleration, thus optimizing fuel usage. However, be mindful of changing road conditions and traffic, and disengage cruise control when necessary to maintain safe following distances.
