Are you considering purchasing a Toyota Prius but unsure about the size of its gas tank? Having an idea of the gas tank capacity is crucial, especially if you plan on taking long trips. In this article, we’ll explore the gas tank capacity of different Toyota Prius generations to help you make an informed decision.
Gas Tank Capacity of the First and Second Generation Toyota Prius

Filling up the gas tank of a Toyota Prius
The first Toyota Prius was introduced in 1997, and the second-generation model was launched in 2003. Both models featured a gas tank capacity of 11.9 gallons. However, the second-generation Prius was outfitted with an updated hybrid powertrain that delivered better fuel economy compared to the first-generation Prius.
The second-generation Prius had a fuel efficiency rating of 48 miles per gallon (mpg) on the highway and 45 mpg in the city. This high fuel efficiency rating, coupled with the 11.9-gallon gas tank, meant that the second-generation Prius could travel up to 570 miles on a single tank of gas.
In 2007, the second-generation Prius was updated with a larger gas tank capacity of 13.2 gallons. The larger gas tank meant that the Prius could travel up to 624 miles on a single tank of gas.
Gas Tank Capacity of the Third Generation Toyota Prius

How the gas tank size of a Toyota Prius has changed over the years
The third-generation Toyota Prius was introduced in 2009 and featured a gas tank capacity of 11.9 gallons, just like the first and second-generation models. However, the third-generation Prius saw significant improvements in its hybrid powertrain, resulting in better fuel economy than its predecessors.
The third-generation Prius had a fuel efficiency rating of 51 mpg on the highway and 48 mpg in the city. This high fuel efficiency rating, coupled with the 11.9-gallon gas tank, meant that the third-generation Prius could travel up to 607 miles on a single tank of gas.
In 2012, Toyota released an updated version of the third-generation Prius with a larger gas tank capacity of 13.2 gallons. The larger gas tank meant that the Prius could travel up to 624 miles on a single tank of gas, just like the second-generation Prius.
As you can see, the gas tank capacity of the Toyota Prius has varied across different generations. In the next section, we’ll explore the gas tank capacity of the fourth-generation Prius.
Gas Tank Capacity of the Fourth Generation Toyota Prius
The fourth-generation Toyota Prius was introduced in 2016 and featured a gas tank capacity of 11.3 gallons. This was a slight reduction from the 11.9-gallon gas tank capacity of the previous three generations. However, the fourth-generation Prius saw significant improvements in its hybrid powertrain, resulting in better fuel economy than its predecessors.
The fourth-generation Prius had a fuel efficiency rating of 54 mpg on the highway and 50 mpg in the city. This high fuel efficiency rating, coupled with the 11.3-gallon gas tank, meant that the fourth-generation Prius could travel up to 609 miles on a single tank of gas.
Compared to the third-generation Prius, the fourth-generation model had a smaller gas tank capacity. However, the improved hybrid powertrain and fuel efficiency rating more than make up for the smaller gas tank.
Advantages and Disadvantages of Different Gas Tank Capacities
Having a larger gas tank capacity means that you can travel further on a single tank of gas. This can be especially useful if you plan on taking long trips or driving in areas where gas stations are far apart. A larger gas tank also means that you don’t have to stop as frequently to fill up, saving you time and reducing the inconvenience of stopping for gas.
On the other hand, a larger gas tank capacity can also mean that your vehicle is heavier and less fuel-efficient. This can result in lower gas mileage and reduced performance. Additionally, a larger gas tank means that you’ll be carrying more gasoline, which can be a safety hazard in the event of an accident.
Conversely, a smaller gas tank capacity can mean that you have to stop more frequently to fill up, which can be inconvenient and time-consuming. However, a smaller gas tank means that your vehicle is lighter and more fuel-efficient, resulting in better gas mileage and performance.
In conclusion, the gas tank capacity of the Toyota Prius has varied across different generations. While having a larger gas tank can be advantageous, it can also result in reduced fuel efficiency and performance. Ultimately, the right gas tank capacity for you will depend on your individual needs and preferences. As you consider purchasing a Toyota Prius, it’s important to weigh the advantages and disadvantages of different gas tank capacities to make an informed decision.
Advantages and Disadvantages of Different Gas Tank Capacities
Having a larger gas tank capacity does come with its benefits. Firstly, you won’t have to stop for gas as frequently, making long-distance trips more convenient. Secondly, you may be able to fill up your tank at a gas station with lower prices, saving you money in the long run.
However, having a larger gas tank capacity also means that you’ll be carrying more weight, potentially leading to decreased fuel efficiency. Additionally, larger gas tanks can be more expensive to fill up, and it may take longer to fill up at the gas station.
On the other hand, having a smaller gas tank capacity can be more advantageous for those who don’t travel long distances often. Smaller gas tanks mean that your car will weigh less, resulting in better fuel efficiency. Additionally, smaller gas tanks are generally less expensive to fill up, and you’ll spend less time at the gas station.
Conclusion
In summary, the gas tank capacity of the Toyota Prius has varied across different generations. The first and second generation Prius models featured an 11.9-gallon gas tank, while the third and fourth generations had both 11.9-gallon and 13.2-gallon options.
It’s crucial to consider your individual needs and driving habits when selecting the right size gas tank capacity for your Toyota Prius. If you frequently travel long distances, a larger gas tank capacity may be more beneficial. However, if you mainly use your car for commuting or shorter trips, a smaller gas tank capacity may be more advantageous.
