2026 Mazda Models by MPG

If you're cross-shopping fuel economy across the 2026 Mazda lineup, the numbers swing more than you'd think between a compact sedan and a three-row SUV. The answer to which 2026 Mazda gets the best MPG depends on whether you're comparing gas-only models, hybrids, or plug-in hybrids.

Below, we break down every efficient model so you can match the right one to your driving habits. If you'd rather see these vehicles in person, you can always browse our new inventory at Bountiful Mazda.

Which 2026 Mazda Gets the Best MPG? Quick Answer

For overall efficiency, the CX-70 PHEV leads the 2026 lineup at an EPA-estimated 61 MPGe combined, with the three-row CX-90 PHEV close behind at 56 MPGe. Among non-plug-in models, the CX-50 Hybrid tops the list at 38 MPG combined (39 city, 37 highway), giving it more than 100 extra miles of range compared to the standard CX-50 2.5 S and 2.5 Turbo trims.

For pure gasoline efficiency with no electrification at all, the Mazda3 Sedan in base 2.5 S FWD trim delivers 30 MPG combined, 27 city and 36 highway. Each of these figures is EPA-estimated, and actual mileage will vary based on driving conditions.

How Fuel Economy Varies Across the 2026 Mazda Lineup

Mazda mileage numbers shift based on engine type, whether the vehicle sends power to two or four wheels, and how much it weighs. A compact Mazda3 and a three-row CX-90 are built for different jobs, and their MPG figures reflect that. These variables explain why a Mazda economy car might get 30 combined MPG while a larger SUV lands in the mid-20s.

Engine Type: Skyactiv-G, Hybrid, and PHEV Explained

Mazda's Skyactiv-G engines are built around high compression ratios, which optimize combustion efficiency without adding hybrid hardware. Most gas-powered Mazda models, including the Mazda3 and CX-5, run on this platform. The CX-50 Hybrid takes a different approach, pairing a gas engine with an electric motor assist that doesn't require plugging in, drawing extra efficiency from stop-and-go driving. The CX-90 PHEV goes further still, combining a 2.5L inline-four engine with a 17.8-kWh battery and a 68-kW electric motor for a combined output of 323 horsepower and 369 lb-ft of torque, paired with an 8-speed automatic and rear-biased AWD.

MPGe, the metric used for the CX-90 PHEV, is the EPA's gasoline-equivalent efficiency rating for electrified vehicles. It's meant for comparison purposes only, and it's worth separating out the CX-90 PHEV's EV-only range, its gas-only MPG after the battery depletes, and its combined MPGe figure, since each tells a different part of the efficiency story.

AWD vs. FWD and Vehicle Size Effects on MPG

Adding all-wheel drive typically knocks fuel economy down a bit due to extra weight and mechanical complexity. The Mazda3 FWD base trim reaches 30 combined MPG, for example, while the AWD Carbon Edition comes in at 29 combined.

The turbo Mazda3 sedan running on regular gasoline lands at 27 combined. Vehicle size matters too. All CX-5 trims come standard with i-Activ AWD, which constantly monitors wheel-load variations, and that standard AWD is part of why the CX-5 sits lower on the MPG chart than the Mazda3 despite sharing a similar engine philosophy.

Gas-Powered Mazda Models: Everyday Efficiency

For shoppers asking "are Mazdas good on gas," the answer largely comes down to which gasoline model you're comparing. The Mazda3 and CX-5 sit at opposite ends of the gas-powered lineup: one built for efficiency-minded commuters, the other for families who need more room.

2026 Mazda3 Sedan and Hatchback

The 2026 Mazda3 Sedan MPG rating leads Mazda's gasoline lineup at 27 city, 36 highway, and 30 combined in base 2.5 S FWD trim. The Hatchback comes in nearly identical at 26 city, 34 highway, 29 combined. Both use a base 186-hp Skyactiv-G 2.5L engine, with an available 2.5L Dynamic Pressure Turbo option producing up to 250 horsepower for those who want more power at some cost to Mazda3 fuel economy.

The Hatchback also offers a 6-speed manual, standard on the 2.5 S Premium trim, for drivers who prefer a more engaged experience. FWD is standard, with i-Activ AWD available on certain trims. This trim suits budget-conscious commuters looking for the most fuel-efficient Mazda car without any electrification.

2026 Mazda CX-30

The CX-30 is the most efficient gas SUV Mazda sells, rated at 24 city, 31 highway, and 27 combined in 2.5 S trim. That edges out the CX-5 by a single combined MPG in a smaller, less expensive package, which makes it worth a look for anyone who wants SUV height and standard i-Activ AWD without the CX-5's footprint.

The available 2.5 Turbo drops efficiency to 22 city, 30 highway, and 25 combined, so the base engine is the pick if mileage is your priority. Best for solo commuters and couples who want a crossover but rarely need the extra cargo room.

2026 Mazda CX-5

The 2026 CX-5 delivers 24 city, 30 highway, and 26 combined MPG across every trim level, the 2.5 S, 2.5 S Select, 2.5 S Preferred, 2.5 S Premium, and 2.5 S Premium Plus. All trims share the same 187-hp Skyactiv-G 2.5L engine, a 6-speed automatic, and standard i-Activ AWD, since no FWD option is offered for 2026. CX-5 fuel economy trails the Mazda3 somewhat, a tradeoff for the extra cargo room and standard all-wheel traction. This model fits buyers who want SUV space and standard AWD without stepping up to a hybrid.

Hybrid Mazda Models: Balancing Power and Efficiency

Mazda's hybrid lineup for 2026 centers on the CX-50 Hybrid, which uses electric assist to push mileage well past what the standard gas CX-50 achieves.

2026 Mazda CX-50 Hybrid

The CX-50 Hybrid posts 39 city, 37 highway, and 38 combined MPG, a substantial jump over the gas-only CX-50 2.5 S (24/30/26) and CX-50 Turbo (23/29/25). For its second model year, added features vary by trim: the Preferred adds a panoramic moonroof and parking sensors, the Premium brings ventilated front seats and an auto-dimming mirror with HomeLink, and the Premium Plus includes heated rear seats, a heated steering wheel, and signature lighting.

It's a rare combination in this class: better mileage paired with more power than the standard CX-50 offers. Drivers who want the most fuel-efficient Mazda SUV without needing to plug in will want to look here first.

Plug-In Hybrid Mazda Models: Maximum MPGe

If you're chasing the highest efficiency number in the entire lineup, the CX-70 PHEV is the model to know.

2026 Mazda CX-70 PHEV

The CX-70 PHEV is the efficiency leader of the entire 2026 lineup at 61 MPGe combined, and it's the model to know if you don't need a third row. Mazda revamped the powertrain for 2026, pushing EPA-estimated electric range up to roughly 30 miles, and the MPGe rating climbed with it. Run the battery down and you're looking at 26 MPG combined on gas alone.

It shares the CX-90 PHEV's 323-horsepower e-Skyactiv setup and rear-biased AWD, but drops the third row in favor of 75.3 cubic feet of cargo space with the rear seats folded. It also starts at $44,450 for the SC trim, several thousand below the CX-90 PHEV. For two-row families with home charging, this is the most efficient Mazda you can buy.

2026 Mazda CX-90 PHEV

The CX-90 PHEV is rated at 56 MPGe combined, with roughly 25 to 26 MPG gas-only once the battery depletes. Kelley Blue Book's 2026 listing specifies 26 combined MPG gas-only, 323 horsepower, a 6.6-second 0-60 mph time, and 27 miles of EV-only range.

It seats up to seven passengers across three rows and can tow up to 3,500 pounds, supported by nearly 50:50 weight distribution and a double-wishbone front suspension for stable handling. The MyMazda App also locates ChargePoint public charging stations, showing available stalls and pricing and allowing in-app payment once your account is linked. This one makes the most sense for families who want meaningful EV range for daily driving with gas backup for longer trips.

Matching a Fuel-Efficient Mazda to Your Lifestyle

With five efficient models to choose from, matching one to your actual driving pattern matters more than chasing the single highest number on the sticker.

Best for Commuting and City Driving

The Mazda3 in base FWD trim is the strongest pick for straightforward commuting, thanks to its 30 combined MPG and compact footprint that's easy to park and maneuver around Salt Lake or Davis County streets. If you want SUV versatility instead, the CX-50 Hybrid's 39 city MPG and extended range make it a strong alternative for drivers who log a lot of stop-and-go miles.

Best for Families and Highway Travel

Families covering long stretches of I-15 will likely lean toward the CX-90 gas model, which seats up to eight passengers and returns 28 MPG highway, or the CX-50 Hybrid at 37 MPG highway for a smaller footprint. The CX-5, with its 30 MPG highway rating, standard AWD, and five-passenger layout, remains a dependable middle-ground choice for Weber County families who want space without stepping up to a three-row model.

Best for Going (Mostly) Electric

For drivers who want to run on electricity for most short trips, the CX-70 PHEV is the efficiency pick at 61 MPGe combined. Choose the CX-90 PHEV instead if you need the third row, since it trades a few MPGe for seating and still tows up to 3,500 pounds. It's the most fuel-efficient Mazda in the lineup for anyone with regular access to home or public charging.

Getting the Best Real-World MPG From Your Mazda

EPA figures are estimates, and actual mileage varies with driving habits, weather, traffic, and vehicle condition. Bountiful winters bring cold starts that temporarily reduce efficiency, since engines and hybrid batteries both run less efficiently until they reach operating temperature. Idling in I-15 traffic between Bountiful and Salt Lake also eats into your MPG, though hybrids and PHEVs actually tend to perform better in stop-and-go conditions, while gas engines hit their stride during steady highway cruising.

Keeping your tires properly inflated helps close the gap between EPA estimates and what you actually see at the pump, and so does staying current on maintenance and driving smoothly. Our team put together some practical tips for getting better gas mileage that apply across the lineup.
