What mileage can I get

Maybe ask ChatGPT or use a search engine?

 

you should be able to get around 50mpg if you stay within the speed limit

 

This is what ChatGP

This is what ChatCP said. I had to reword the question just a little.

"The Toyota Prius Prime is a plug-in hybrid electric vehicle (PHEV) that can run on both electricity and gasoline. It has an electric range of approximately 25 miles before it switches to gasoline power.

When driving on the freeway, the Prius Prime's fuel efficiency will primarily depend on its gasoline engine since it is not operating in electric mode. The EPA estimated fuel economy for the Prius Prime in hybrid mode is 54 miles per gallon (MPG) combined city/highway driving. However, since you mentioned driving 120 miles on the freeway per week, let's assume that the majority of your freeway driving is at a constant speed, which can potentially improve your fuel efficiency.

For in-town driving, the Prius Prime can operate in electric mode, which means it consumes minimal or no gasoline. However, the electric range is limited to about 25 miles, after which the vehicle will switch to hybrid mode.

Considering your driving habits, which include 120 miles on the freeway per week and the remainder in-town, it's challenging to provide an exact MPG figure without knowing the specific breakdown of your in-town mileage and the exact conditions of your driving. However, we can make an estimation based on the available information.

Let's assume the following breakdown:

• 120 miles on the freeway per week: Assuming your Prius Prime is operating in hybrid mode during freeway driving, and you achieve a conservative estimate of 50 MPG.
• The remaining mileage in-town: Assuming you complete approximately 7,000 miles in-town per year (approximately 135 miles per week) and your Prius Prime operates in electric mode for about 25 miles before switching to hybrid mode, resulting in a conservative estimate of 50 MPG for in-town driving.

To calculate the overall fuel efficiency, we can use the weighted average based on your weekly mileage: (120 miles/week * 50 MPG + 135 miles/week * 50 MPG) / (120 miles/week + 135 miles/week) = (6000 + 6750) / 255 = 52.9 MPG

Therefore, with the given assumptions and driving habits, you can expect an estimated fuel efficiency of around 52.9 MPG for your Prius Prime plug-in with 100k miles. Keep in mind that this is just an approximation, and actual results may vary based on driving conditions, maintenance, and other factors."

 

Now if we could just get ChatGPT to troll itself and argue about the details so we wouldn't have to write out our own opinions/experience and we could just watch...

 

I have 172k and still averaging as much as 60mpg on a daily 150-160 miles plug in every night.

 

I have 115 K mi , and did 200 highway miles per week and have a lifetime mpg of 83.6
