14 MPG combined. That’s the reality for anyone considering a 2025 Chevrolet Corvette Z06. Nobody buys a Z06 for fuel efficiency. This isn’t just transportation; it’s a statement. It’s an unapologetic commitment to raw performance, loud exhaust sounds, and the thrill of a naturally aspirated, flat-plane crank V8 that revs to 8,600 rpm. The target buyer enjoys track days, weekend drives, or simply the experience of driving a world-class performance machine and is willing to accept the gas costs.

City and highway performance

The Z06’s EPA ratings are 12 MPG in the city and 20 MPG on the highway. The city figure shows the engine’s high fuel consumption in stop-and-go traffic, where the 5.5-liter V8 can’t operate at its best. The highway number offers a glimpse of what’s possible with a light foot and consistent speed, but achieving 20 MPG on the open road requires serious restraint, which few Z06 owners will maintain for very long.

Annual fuel cost

The EPA estimates an annual fuel cost of $4,150 for the 2025 Corvette Z06. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using the national average fuel price at the time. It’s a significant amount, potentially exceeding monthly payments for a more economical car. However, Z06 buyers likely view this cost as the price to own a high-performance vehicle. It’s a calculated expense as part of ownership.

Real-world expectations

Real-world fuel economy for the Z06 is highly driver-dependent, so forget the EPA numbers. Track days will greatly impact fuel consumption, pushing MPG into the single digits. Spirited drives won’t be much better. Even with conservative driving, matching the EPA combined number will be a challenge. Expect to average somewhere between 10-16 MPG in mixed driving, and potentially lower if you regularly enjoy the Z06’s performance.

How it compares

Comparing the Z06’s fuel economy to other performance cars shows its relative inefficiency. A Porsche 911 GT3, with its equally impressive naturally aspirated engine, gets around 15 MPG city and 19 MPG highway, slightly better than the Z06. A Ford Mustang Shelby GT500 also has similar fuel consumption. A BMW M4 Competition, with its turbocharged engine, beats the Z06 with around 16 MPG city and 23 MPG highway. However, none of these offer the unique engine and experience of the Z06’s flat-plane crank V8. Buyers aren’t cross-shopping for the best MPG; they’re seeking an unfiltered driving experience that other cars can’t replicate. Find all Chevrolet fuel economy data on our site.

Tips to maximize efficiency

While the Z06 isn’t designed for fuel efficiency, some measures can subtly improve your MPG. Gentle acceleration from a standstill is crucial. Avoid aggressively flooring the throttle, as this instantly uses more fuel. Instead, aim for smooth acceleration.

Use the car’s driving modes. Despite its performance, the Z06 provides different modes that adjust engine mapping and throttle response. Selecting a milder mode, like “Tour,” can slightly improve fuel economy during everyday driving, though it will dial back the car’s responsiveness.

Maintain proper tire pressure. Inflated tires reduce rolling resistance, improving fuel economy. Check your tire pressure regularly and ensure it matches the recommended levels. This is important after track days, as tire pressures can change during high-performance driving.

Minimize idling. Letting the Z06 idle for extended periods wastes fuel, especially when the engine is cold. Reduce unnecessary idling by turning off the engine whenever you anticipate stopping for more than a minute or two. This can make a difference.

Anticipate traffic flow. Planning your routes to avoid congested areas can improve fuel economy. Use navigation apps to identify potential delays and reroute to smoother roads. Maintaining a consistent speed and avoiding frequent stops will help optimize fuel efficiency.
