How big is the fuel tank on a Toyota Grand Highlander Hybrid?
The Toyota Grand Highlander Hybrid has a fuel tank capacity of 17.1 to 17.2 gallons, depending on the trim level, with the Hybrid MAX models holding slightly more. However, owners report that the actual usable fuel is often less than the advertised capacity, with many filling up only around 11-12 gallons even after the fuel light comes on, due to a large reserve designed to protect the hybrid system.
Fuel tank capacity by trim
- Hybrid LE/XLE: 17.1 to 17.2 gallons
- Hybrid MAX (Limited/Platinum): 17.2 gallons
Important considerations
- Usable vs. advertised capacity: It's common for the fuel gauge to read empty and only be able to add around 11-13 gallons, even though the advertised capacity is higher. This is not a defect but a designed feature with a large fuel reserve.
- Purpose of the reserve: This large reserve is intended to prevent the fuel pump from running dry and to protect the hybrid system's components.
- Driving range: The actual driving range will vary based on driving style, but with the larger tank, the vehicle can achieve a significant driving range before needing a refill, even if not all the fuel is used at once.
