26 MPG combined. That’s the headline for the 2023 Toyota GR Supra 3.0L, and while it might not sound impressive in a world of hybrid crossovers, it’s a reasonable figure for a performance coupe designed to deliver thrills. This isn’t a car purchased by someone overly concerned with squeezing every last mile from a gallon. It’s about sharp handling, a potent engine, and head-turning style; traits that the Supra delivers on.

City and highway performance

The EPA estimates 23 MPG in the city and 31 MPG on the highway for the 2023 GR Supra 3.0L. The city figure reflects stop-and-go traffic, frequent acceleration, and idling, conditions that penalize fuel economy. Even in urban environments, the smooth power delivery of the inline-six and the responsiveness of the eight-speed automatic transmission can make the drive enjoyable. The highway rating of 31 MPG is attainable during steady-state cruising. Longer road trips are manageable, if you can resist the urge to exploit the engine’s power on open stretches of road.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Toyota GR Supra 3.0L is $2,250. This figure is based on driving 15,000 miles per year and using national averages for fuel prices. This is a projection, of course, and your actual cost will vary depending on your driving habits, the type of fuel you use, and local fuel prices. However, it provides a standardized benchmark for comparing running costs with other vehicles. Premium fuel is recommended for optimal performance, which will influence your real-world fuel expenses.

Real-world expectations

While EPA estimates offer a useful baseline, real-world MPG often differs. GR Supra owners tend to be enthusiastic drivers, and the temptation to exploit the engine’s capabilities can significantly impact fuel economy. Expect to see numbers closer to the EPA estimates if you prioritize smooth acceleration and highway cruising. However, spirited driving, track days, or frequent use of the car’s sport modes will likely lower your average MPG. The Supra is a car that encourages engagement, and that translates to a less fuel-efficient driving style. Check out GR MPG across all years.

How it compares

The GR Supra’s fuel economy places it in the middle of the pack for performance coupes. For instance, the BMW Z4 M40i, which shares its engine with the Supra, achieves a similar 25 MPG combined. The Porsche 718 Cayman S, with its turbocharged four-cylinder engine, offers a slightly better 28 MPG combined. On the other hand, the Ford Mustang GT with its 5.0L V8, struggles to reach 18 MPG combined. The Audi TT RS, another performance all-wheel-drive coupe, manages around 22 MPG combined. Slight differences in fuel economy between these cars are unlikely to be a deciding factor for the Supra buyer. Performance, handling, and overall driving experience are more influential in this segment.

Tips to maximize efficiency

The GR Supra’s automatic transmission offers different drive modes, Eco, Normal, and Sport. Using the Eco mode during relaxed driving, like highway cruising, can make a difference in fuel consumption. This mode adjusts throttle response and shift points to prioritize efficiency over performance.

Avoid aggressive acceleration and hard braking. Smooth, gradual inputs are better for fuel economy and contribute to a more comfortable and controlled driving experience, especially in a car as responsive as the Supra. Anticipate traffic flow and maintain a consistent speed whenever possible.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Check your tire pressure regularly, every few weeks, and inflate them to the recommended pressure specified on the door jamb sticker.

Consider the weight you’re carrying. Removing unnecessary items from the car’s trunk and cabin reduces the overall weight the engine has to move, leading to better fuel efficiency. It’s a small difference, but it helps, particularly in a car with sporting intentions where weight is important. See all Toyota fuel economy data.
