The 2025 Mazda CX-70 4WD 3.3L 6-cyl gets 25 MPG combined. This comes from its 3.3L inline-six and eight-speed automatic transmission. The CX-70 is a mid-size SUV that balances power and refinement with efficiency. This vehicle suits individuals or small families who like Mazda’s premium driving and design, but still want reasonable running costs. They buy the CX-70 for its composed performance and strong capability in tough weather, with 25 MPG combined being an acceptable figure for its character.

City and Highway Performance

The combined figure shows a difference in the CX-70’s performance in different driving conditions. In city driving, the 2025 Mazda CX-70 4WD achieves 23 MPG. This reflects stop-and-go traffic, where the vehicle’s weight and repeated acceleration naturally use more fuel. However, considering its all-wheel-drive system and 3.3-liter engine, 23 MPG in the city is a good effort for an SUV built for premium goals. On the open road, the CX-70 performs well, delivering 28 MPG Highway. Here, the smooth dynamics of the inline-six and the intelligent shifts of the automatic transmission allow the engine to settle into its most efficient RPM range. Long-distance drivers will find this highway efficiency appealing, reducing the fuel cost over extended trips.

Annual Fuel Cost

The EPA estimates an annual fuel cost of $2,300 for the 2025 Mazda CX-70 4WD 3.3L 6-cyl. This is based on a standard method: driving 15,000 miles per year, with 45% highway miles and 55% city miles, using national average fuel prices. For a typical CX-70 owner, this estimate gives a benchmark for yearly running costs. They expect these costs for a vehicle offering this level of performance, luxury, and all-weather capability, and $2,300 per year fits within their expectations for a premium mid-size SUV. This is not a budget purchase; it’s a value where engineering and driving pleasure are weighed against predictable fuel expenses.

Real-World Expectations

Owners of the 2025 Mazda CX-70 4WD with the 3.3L engine report fuel economy figures that generally match the EPA’s estimates, though individual results will differ. Drivers with a heavier foot or those in congested cities should expect numbers closer to the 23 MPG city rating, or slightly below if their commute involves frequent, aggressive acceleration and braking. Conversely, those who mainly drive on highways or use a more conservative driving style will likely achieve, and sometimes exceed, the 28 MPG highway figure. The CX-70’s mild-hybrid system, with its inline-six, assists in reducing fuel consumption, especially during start-stop scenarios and gentle acceleration, helping with its real-world performance. The vehicle’s driving mode selection also matters; using Sport mode frequently will reduce efficiency, while Normal or Off-Road modes balance power delivery and fuel use.

How It Compares

The 2025 Mazda CX-70 4WD 3.3L six-cylinder offers an engaging driving experience and good efficiency. For instance, a Jeep Grand Cherokee Laredo 4WD with its 3.6L V6 typically gets 21 MPG combined (19 City / 26 Highway). The CX-70’s 25 MPG combined is more efficient, especially since its 3.3L engine delivers more torque and refined power. A BMW X5 xDrive40i, a luxury competitor with a 3.0L turbocharged inline-six, gets 23 MPG combined (21 City / 27 Highway). While the X5 is slightly less efficient, the comparison is close enough that a buyer prioritizing Mazda’s driving dynamics and value would find the CX-70’s MPG competitive. Even a Genesis GV80 3.5T AWD, another premium competitor, gets around 20 MPG combined (18 City / 23 Highway), making the CX-70 significantly more fuel-efficient. The CX-70 shows that a powerful, premium, and driver-focused SUV does not have to use a lot of fuel. Its fuel economy reflects Mazda’s commitment to delivering a balanced package that appeals to those who appreciate a powerful and luxurious vehicle, without excessive trips to the pump.

Tips to Maximize Efficiency

Maintaining smooth driving habits is important for maximizing the CX-70’s fuel efficiency. Avoid abrupt acceleration and hard braking. Instead, anticipate traffic and let the mild-hybrid system manage power delivery and regeneration.

Regular maintenance, especially proper tire inflation and timely oil changes, directly impacts fuel economy. Underinflated tires increase rolling resistance, making the engine work harder.

Use the available driving modes wisely. While the CX-70’s Sport mode is engaging, it prioritizes performance over efficiency. Sticking to Normal or Off-Road mode for typical driving can lead to better MPG figures.

Minimize unnecessary weight in the vehicle. Removing heavy items from the cargo area and avoiding carrying excessive gear will contribute to better fuel economy.

Strategically plan your routes and combine errands. Minimizing cold starts and short trips, where the engine is less efficient, will allow the CX-70’s powertrain to operate at its optimal temperature more often.
