How many miles per gallon does a Toyota Sienna get on the highway?
The current Toyota Sienna, redesigned for 2021, is a hybrid-only minivan and is known for strong highway efficiency. On the highway, most models achieve about 36 miles per gallon, with slight variations by drivetrain, year, and tires.
Highway fuel economy by generation and drivetrain
EPA highway estimates for the current generation (2021–present) reflect two main configurations. The numbers below summarize typical highway performance and note where there can be differences.
EPA highway estimates for the current generation Sienna by drivetrain:
- 2021–present Toyota Sienna (hybrid)
- Front-Wheel Drive (FWD): approximately 36 mpg on the highway (EPA)
- All-Wheel Drive (AWD): typically mid-30s on the highway, roughly 34–36 mpg depending on year and tire setup
In practice, real-world highway mileage varies with terrain, driving speed, climate control use, tire condition, and load. The highway figure is a guideline based on EPA testing and may differ from your actual experience.
Older Sienna generations (pre-hybrid)
Before the hybrid era, Sienna models used a 3.5-liter V6 with a traditional gasoline powertrain. Highway fuel economy for those generations was typically around the high 20s mpg, with variations by year, transmission, and equipment.
- Pre-hybrid Sienna (pre-2021): Highway mpg generally around 27 mpg, varying by year and configuration
Again, real-world highway mileage for older Sienna generations depended on factors such as engine tuning, drivetrain choice, tires, and overall vehicle condition.
How to maximize highway mpg in a Sienna
For drivers aiming to squeeze the most highway efficiency out of a Sienna, consider the following practices.
- Maintain correct tire pressure and use tires recommended by Toyota; underinflated tires reduce efficiency
- Adopt steady speeds and use cruise control on long, flat highway segments
- Avoid excessive idling and keep A/C usage moderate in warm weather
- Plan efficient routes to minimize hills and stop-and-go traffic
With mindful driving habits, highway mileage can approach the EPA estimates more consistently.
Summary
The modern Toyota Sienna, built as a hybrid-only minivan since 2021, typically delivers about 36 mpg on the highway in its FWD configuration, with AWD models often in the mid-30s depending on year and tires. Older, non-hybrid Siennas historically achieved around 27 mpg on the highway. Always check the latest EPA ratings for your exact year and configuration, and remember that actual mileage varies with driving conditions and maintenance.
