26 MPG combined won’t win any hypermiling awards, but it’s a perfectly reasonable figure for the 2024 Toyota GR Supra 3.0L. This isn’t transportation for the masses; it’s a focused performance machine. The target buyer isn’t prioritizing fuel efficiency above all else. They crave the thrill of a boosted inline-six, the agility of a finely tuned chassis, and the head-turning style that the Supra delivers. This level of fuel consumption is the price of admission.
City and highway performance
The EPA estimates for the GR Supra 3.0L break down to 23 MPG in the city and 31 MPG on the highway. The city figure reflects stop-and-go traffic, where accelerating from a standstill and frequent braking impact fuel consumption. The highway estimate suggests that when cruising at a steady speed, the Supra can use its efficient engine and aerodynamic design to sip fuel more conservatively. The eight-speed automatic transmission plays a key role in optimizing fuel economy, shifting smoothly and precisely to keep the engine in its most efficient operating range. However, Supra drivers know that the temptation to downshift and unleash its power will often override any desire for optimal fuel efficiency.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2024 Toyota GR Supra 3.0L is $2,250. This is based on driving 15,000 miles per year and using national average fuel prices. These figures can change depending on your driving habits and local gasoline prices. Aggressive driving, extended idling, and neglecting routine maintenance can all negatively impact fuel economy and increase your annual spending at the pump. Using fuel-saving techniques (detailed below) can help bring that number down closer to the EPA estimate. The type of fuel used also plays a role. Premium fuel is recommended for optimal performance, and variations in octane prices can affect the overall annual fuel cost.
Real-world expectations
While the EPA estimates provide a useful benchmark, real-world fuel economy can vary considerably based on driving style, traffic conditions, and even the weather. A driver who enjoys the Supra’s performance will likely see numbers below the EPA estimates. A more conservative driver who prioritizes smooth acceleration and avoids unnecessary braking might achieve slightly better fuel economy. Terrain also plays a role; hilly or mountainous areas can increase fuel consumption compared to flat terrain. If you spend most of your time in congested urban areas, expect your average MPG to be closer to the city estimate. Those who frequently embark on long highway trips can anticipate achieving numbers closer to the highway estimate.
How it compares
The Supra’s fuel economy positions it competitively in its segment. The BMW Z4 M40i, which shares its engine and much of its chassis with the Supra, achieves a similar 25 MPG combined. The Porsche 718 Cayman, despite its mid-engine layout and focus on handling, manages a comparable 24 MPG combined in its base configuration. A Nissan Z, with its powerful V6, lands around 22 MPG combined. These comparisons highlight that high performance and engaging driving dynamics often mean less gas. If maximizing MPG is your top priority, other vehicles such as a Toyota Prius (52 MPG combined) are better suited. Enthusiasts weighing cars like these are making a trade-off, sacrificing efficiency for a unique driving experience. You can also view all Toyota fuel economy data across their lineup.
Tips to maximize efficiency
Smooth and steady acceleration is key to maximizing fuel economy in the GR Supra. Avoid abrupt acceleration and hard braking, as these actions consume significantly more fuel. Strive for gradual acceleration and anticipate traffic conditions to minimize the need for sudden stops. Using cruise control on the highway can also help maintain a consistent speed and improve fuel efficiency.
Be sure that your GR Supra is properly maintained. Regular tire pressure checks are critical, as underinflated tires increase rolling resistance and reduce fuel economy. Following the recommended maintenance schedule, including oil changes and air filter replacements, will also help keep the engine running efficiently.
Consider using the Supra’s different driving modes to optimize fuel economy. The “Normal” mode typically provides a more relaxed throttle response and less aggressive transmission mapping compared to the “Sport” mode, which can encourage more spirited driving and higher fuel consumption. Experiment with the different modes and see how they affect your MPG.
Minimize unnecessary weight in the vehicle. Removing heavy items from the trunk or rear seats can slightly improve fuel economy, as the engine doesn’t have to work as hard to accelerate and maintain speed. While the effect may be minimal, every little bit helps. Consider taking on the task with your next oil change.
Pre-plan your routes to avoid congested areas whenever possible. Stop-and-go traffic is a major fuel economy killer, so choosing routes with smoother traffic flow can improve your MPG. Even if it adds a few minutes to your commute, the fuel savings can be worth it. You can also browse the GR MPG across all years.
