How far can the 2021 Toyota Prius go on a tank of gas?

When you get down to it, the calculation for range is pretty simple. It’s just fuel tank capacity multiplied by the mpg figure. Of course, we have three mpg figures. Your range can definitely vary whether you are driving in the start-and-stop city or whether you are cruising out on the highway, and a hybrid actually usually does better in the city.

However, to provide the most useful range figures, we are going to use the combined mpg to come to our range figures. What is the combined mpg though? It’s actually derived from the other two numbers, hence its name. If you take 55% of the city figure and add it to 45% of the highway figure and add them together, you will arrive at the combined figure. Below are the combined range figures for each Prius model.
