2018 Toyota Prius Prime: Massive MPG

We’ve been driving our 2018 Toyota Prius Prime around the Atlanta metro area for a few months now, using charging stations whenever possible and plugging in at home, and the results have been somewhat astonishing. In case you weren’t aware, the plug-in hybrid runs off electric power for about 30 miles before switching to the 4-cylinder engine to provide power to the wheels. The Prius Prime also regains some electric power through regenerative braking and coasting, replacing power in the battery and thereby prolonging the amount of time between gasoline refills at your local service station. Admittedly, we expected high fuel economy numbers, but nothing even close to what we experienced.

Numbers Don’t Lie

On our first trip to the gas station our Prius Prime had only 121 miles on the odometer — quite possibly the newest car we’ve received in the last several years. That first trip to the gas station was on October 4th 2017. Our next trip to fill up the tank came three and half months later, longer than most of Taylor Swift’s relationships. Aside from the amount of time between trips to the gas station, there was the staggering 2,036 miles traveled on that tank of gas. When divided by the 8.66 gallons used in that time period, fuel economy equates to a whopping 235.1 miles per gallon!

In Comparison

To put the incredible fuel economy of the Prius Prime in perspective, our 2017 Infiniti Q50 has averaged 23.9 miles per gallon over the same period, including long stretches of highway-only driving; or roughly one tenth the fuel economy. While the Q50 isn’t as much like the Prius Prime as it is a midsize luxury sport sedan, our compact 2017 Subaru Impreza was roughly the same size as the Prius Prime and returned a mere 28.9 miles per gallon while being driven mostly on the highway as well, over the same period of time.  Admittedly, the Impreza and the Q50 aren’t hybrids, but they are vehicles currently in our long term fleet that have returned good fuel economy based on our observations.  That being said, the excellent fuel economy comes at a premium, with the base price of the Prius Prime coming in at about $3,500 more than a base Prius and almost $9,000 more than a base Impreza.  

 There’s one thing to keep in mind, however: Almost all of the mileage accumulated on the 2018 Toyota Prius Prime was accumulated during city driving, with short bursts of highway cruising as well. With the keys now rotating to staff members who live further away from the office, it will be interesting to see if the Prius Prime will be able to maintain the incredibly high fuel economy it has managed to achieve so far. Find a 2018 Toyota Prius Prime for sale

  1. How much did you have to pay for the electricity in that time frame/mileage?  I get the good gas mileage since this is an electric car that only uses gas when it runs out of battery charge but how much more money in electricity did you pay? I know we have had to pay quite a bit for our electrical bill when we have a freezer or our A/C/ unit plugged in/running.  That would help us to know if this is really a good trade off.
