25 MPG combined, a figure from a plug-in hybrid system, positions the 2025 Mazda CX-70 4WD PHEV 2.5L 4-cyl for a specific type of buyer. This isn’t a stripped-down commuter; it’s a premium, mid-size two-row SUV designed for those who appreciate upscale driving dynamics, genuine all-wheel-drive capability, and a refined interior. These buyers also value the substantial electric range a PHEV offers before the gasoline engine takes over. The 25 MPG combined isn’t its headline act, that’s its impressive EV range, but it’s a strong showing for a substantial vehicle tasked with accommodating families and their gear with Mazda’s signature driving engagement. This CX-70 is for the suburban driver whose daily commute is often within the electric buffer, but who frequently ventures further afield, unwilling to compromise on comfort, power, or that distinctive Mazda feel.

City and highway performance

Looking at the specifics, the 2025 Mazda CX-70 4WD PHEV achieves 24 MPG in the city and 27 MPG on the highway. These numbers illustrate the powertrain’s bias and its ideal operational environment. The slightly lower city MPG relative to highway figures might seem unusual for a PHEV, but it shows the efficiency of the electric motor doing most of the work in stop-and-go traffic. Once the electric range is depleted, or the driver demands aggressive acceleration, the 2.5L four-cylinder engine engages. In city driving, especially with frequent starts and stops that allow for regenerative braking, the system is designed to maximize electric assist, even beyond the specified EV range. On the highway, where sustained speeds mean continuous engine operation once the battery is depleted, the 2.5L engine paired with the smooth automatic (S8) transmission operates capably, delivering solid efficiency for its class. For drivers who primarily use their CX-70 for daily errands and a shorter commute, the gasoline engine will remain dormant for significant periods, leading to gasoline consumption far lower than the EPA estimates suggest.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,300 for the 2025 Mazda CX-70 4WD PHEV 2.5L 4-cyl. This figure is based on a standardized calculation assumption: driving 15,000 miles per year with a mix of 45% highway and 55% city driving, and using national average fuel prices. It’s crucial to understand that for a plug-in hybrid, this $2,300 primarily reflects the cost of gasoline, with electricity costs factored separately. For many CX-70 PHEV owners, this annual fuel cost will be a ceiling rather than an average. Drivers diligent about charging at home or work, and whose daily driving habits fall within the vehicle’s substantial electric range, will find their gasoline consumption, and thus their actual annual outlay for fuel, significantly lower. The $2,300 figure represents the cost for a driver who is not maximizing their electric range or who consistently drives long distances beyond the battery’s capability. Those who plug in frequently and have shorter commutes should anticipate substantial savings on gasoline, trading that cost for a (typically less expensive) electric bill.

Real-world expectations

Expectations for the CX-70 PHEV’s fuel economy need to be calibrated to its mission. This is not a minimalist, efficiency machine. It’s a premium, mid-size SUV that prioritizes refinement, comfort, and performance. The 2.5L four-cylinder engine, when running, provides ample power, especially when augmented by the electric motor. The all-wheel-drive system ensures confident traction in various conditions, a major draw for its target audience. Real-world fuel economy for the 2025 CX-70 PHEV owners will heavily depend on their charging habits and typical usage patterns. If you frequently drive less than the EV range (which is quite generous here) and consistently plug in, your gasoline fill-ups will be rare, and your overall energy cost will be dominated by electricity. If you’re consistently undertaking long road trips without opportunities to charge, then the 25 MPG combined essentially means you’re operating a very efficient conventional gasoline SUV, still a respectable number for its size and AWD system. The appeal of this CX-70 isn’t just the 25 MPG combined, but the flexibility it offers: zero-emission local driving combined with the peace of mind of a gasoline engine for longer journeys, all wrapped in a luxurious, engaging package. This is a vehicle for those who appreciate the best of both worlds.

How it compares

The 2025 Mazda CX-70 PHEV steps into a competitive segment, but its unique blend of features and Mazda’s driving philosophy sets it apart. Comparing its 25 MPG combined to other premium mid-size PHEV SUVs reveals its position. Consider the Audi Q5 55 TFSI e quattro, another luxury PHEV SUV. It delivers 26 MPG combined, nudging slightly ahead of the CX-70, but typically at a higher price point and with a different driving character. The Volvo XC60 Recharge T8 offers a similar 36 MPG combined (when factoring in its electric range), but its driving dynamics and interior aesthetics have a distinct Scandinavian flavor that may not appeal to the Mazda buyer seeking a more driver-centric experience. On the more mainstream side, a non-PHEV like the Honda Passport AWD manages around 21 MPG combined, illustrating the efficiency benefit the CX-70’s hybrid system brings even when its battery is depleted. The CX-70 is positioned against vehicles that prioritize luxury and performance, and within that context, its 25 MPG combined is a strong showing. It’s not striving to be the absolute most efficient PHEV on the market, but rather a driver’s SUV that happens to offer significant electric range and strong fuel economy when running on gasoline.

Tips to maximize efficiency

Using the full potential of your 2025 Mazda CX-70 4WD PHEV’s fuel economy requires a mindful approach, particularly regarding its electric powertrain. The key is to maximize electric-only driving whenever possible.

Always plug in your CX-70 when you have access to a charger, whether at home, work, or public charging stations. Maximizing the electric range means you’ll delay the engagement of the gasoline engine, significantly reducing your fuel consumption and pushing your combined MPG much higher than the EPA’s blended estimate.

Pay attention to your driving style. Smooth acceleration and gentle braking, particularly using the regenerative braking capabilities, will not only conserve electricity but also make the transition to the gasoline engine less frequent and more efficient. Avoid aggressive starts and stops that drain the battery faster.

Consider using the available drive modes. Sport mode will inherently prioritize performance and likely engage the gasoline engine more readily, even when battery charge is available. Opt for normal or eco modes for daily driving to encourage electric-only operation and optimize overall efficiency.

Keep your tires properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine (or electric motor) to work harder and reducing efficiency, no matter the powertrain. Regular checks can save you both fuel and tire wear.
