22 MPG combined is exactly what buyers expect from a modern, rear-wheel-drive, turbocharged sports coupe like the 2025 Nissan Z 3.0L 6-cyl automatic. This isn’t a family hauler or a commuter appliance; it’s a dedicated enthusiast machine designed for visceral thrills and engaging performance. The Z’s mission is to deliver potent acceleration, responsive handling, and iconic styling, and its fuel economy figures reflect a powertrain tuned for that purpose. Those drawn to the Z prioritize the driving experience above all else, understanding that a potent twin-turbo V6 and exciting dynamics naturally come with a certain thirst for premium fuel.

City and highway performance

For the specifics, the 2025 Nissan Z with the 3.0L twin-turbo V6 and 9-speed automatic transmission is rated at 19 MPG in the city and 28 MPG on the highway. The city figure of 19 MPG is entirely predictable for a high-performance engine in stop-and-go driving. The VR30DDTT engine, while having 400 horsepower, still needs to move nearly 3,600 pounds. In urban environments, frequent acceleration from a standstill and varied speeds mean the turbos are more active, and the engine operates in less efficient parts of its powerband. Enthusiasts understand this trade-off; the gratification of merging onto a freeway or blasting away from a green light is precisely why they choose a car like the Z.

The highway rating of 28 MPG is arguably more impressive, showcasing the efficiency benefits of modern powertrain engineering. The 9-speed automatic transmission plays a critical role here, offering a broad range of ratios, including taller gears for improved cruising efficiency. At steady highway speeds, the VR30DDTT engine can settle into a lower RPM, allowing the turbos to spool less frequently and the engine to operate closer to its optimal fuel economy window. This highway figure makes the Z a perfectly capable companion for spirited weekend road trips, where the excitement of the drive is as much a part of the journey as the destination.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,650 for the 2025 Nissan Z 3.0L 6-cyl automatic. This figure is calculated based on several standardized assumptions: driving 15,000 miles per year, with 45% of that mileage in city driving and 55% in highway driving, and using national average fuel prices, which the EPA updates regularly. It is crucial to understand that this $2,650 is an estimate, a useful benchmark for comparison rather than an exact prediction of every individual’s annual expense. Actual costs will fluctuate based on local fuel prices, personal driving habits, and the proportion of city versus highway mileage driven. For the Z buyer, this annual cost is a known quantity, a part of the ownership experience that is comfortably absorbed for the joy of piloting such a capable and engaging machine. Someone choosing a Z typically is not making their purchase decision based on minimizing quarterly fuel bills.

Real-world expectations

In real-world driving, owners of the 2025 Nissan Z 3.0L 6-cyl with the automatic transmission should anticipate figures closely mirroring, or perhaps slightly below, the EPA estimates, depending heavily on their driving style. This vehicle encourages enthusiastic driving, the intoxicating pull of 400 horsepower and 350 lb-ft of torque often tempts drivers to exploit the engine’s full potential. When driven hard, engaging in frequent full-throttle acceleration or carving through winding roads, fuel economy will inevitably dip. This is not a deficiency of the Z but a natural consequence of using its performance capabilities. Conversely, disciplined drivers who spend more time cruising on highways might even see numbers at or slightly above the 28 MPG highway rating. Ultimately, the Z delivers on its promise of accessible sports car performance, and its fuel economy is reflective of that mission, largely dictated by the foot of the driver.

How it compares

When stacking the 2025 Nissan Z 3.0L Automatic against its direct competitors, its 22 MPG combined figure holds a strong, competitive position. The Toyota GR Supra 3.0, sharing a similar performance ethos and also featuring a turbocharged inline-six (though a BMW-sourced unit), achieves an identical 22 MPG combined (20 city / 28 highway) with its automatic transmission. This parity highlights that modern 400+ horsepower sports coupes, even with engineering, converge around this MPG envelope. Consider the Ford Mustang GT with its 5.0L V8 and 10-speed automatic, it typically registers around 18-19 MPG combined (15 city / 24 highway), demonstrating the efficiency advantage the Z’s turbocharged V6 offers over a larger displacement naturally aspirated engine. Even the smaller, less powerful Subaru BRZ, with its 2.4-liter naturally aspirated flat-four, comes in at 23 MPG combined (21 city / 30 highway) for its automatic variant, showing the Z’s V6 isn’t far behind a significantly less powerful car. The Z’s fuel economy makes a clear case: it delivers genuine sports car performance without falling significantly behind its peers, especially when factoring in its potent output.

Tips to maximize efficiency

While the Nissan Z is built for performance, adopting mindful driving habits can slightly improve your fuel economy without completely sacrificing the fun. Smooth and gradual acceleration is key, avoid jerky inputs and heavy throttle unless the situation truly demands it.

Anticipate traffic flow and road conditions to minimize unnecessary braking and acceleration. Maintaining a consistent speed on the highway, especially using cruise control, helps the 9-speed automatic keep the engine in its most efficient range.

Keep your tires properly inflated to the manufacturer’s recommended pressures. Underinflated tires increase rolling resistance, making the engine work harder and consuming more fuel.

Regular maintenance, including timely oil changes and air filter replacements, ensures the VR30DDTT engine operates at peak efficiency. A well-maintained engine runs smoother and more effectively, translating to better fuel economy.
