I have a 2025 Limited (fwd) that I purchased a little over a week ago. It had 600mi on it at purchase, and has over 2,000 miles today. I reset the “lifetime” mpg to hopefully get a more accurate picture of “my” mpg. Obviously, most of those miles are highway miles. Even more so, they were the road trip kind of highway miles where I either wanted or really needed to be in a hurry to make it where I needed to be on time, like the middle of the week drive home from an out of state dealership, or a road trip to see Blink-182 that I left late for work to get started on. Needless to say, on the road trips I probably averaged around 80-85mph, often traveling faster for decent distances. Anyway, I’m only averaging 44.6mpg, and that’s after using 2-3 days of work commute with cruise control set to 72mph in an effort to see how well it would do. With cruise at 72mph, it still only averaged 46.8mpg, which means I guess that’s probably the “peak” of what I’ll ever see with this one. I guess my point being, I am definitely a little disappointed in this generation strictly from a fuel economy perspective. I feel like my Gen 4 was way more fuel efficient. When I traded it in a few years ago, my Gen 4 was showing 49.x on the fuel economy and it was also only ever really driven on the interstate at 80-85mph. Is the Gen 5 just not meant for being as efficient on the highway? Or will it improve over time? Overall, Gen 5 is definitely an improvement literally everywhere else (except the cargo area).
Seems to be a slight dip in Fuelly reported mpg, compared to 4th gen, a mile or two per gallon: Toyota Prius MPG - Actual MPG from 9,280 Toyota Prius owners Something skewing the 2025 numbers, lol.
you traded efficiency for looks. not a bad compromise if it is helping prius sales, but i wish they had one efficient trim or something.
Out of curiosity, what was the trim level of your gen4? You should see a mild improvement to your current mpg. I've got the AWD version and I'm seeing about 45-47mpg on average when I drive a variety of speeds. You should see 3-5mpg better than that. I'm getting roughly: 38-42mpg at 85-90mph(only when I visit Chicago) 42-45mpg at 75-85mph(my local interstate speed limit is 80) 45-48mpg at 65-75mph 48-52mpg at 55-65mph 55ish mpg at 50mph (obviously those number vary by wind and terrain - I live in an extremely flat area with strong winds) I drop back down to 45-48mpg in city driving because I live in a small town and my city trips are usually 2 miles or less.
Previous trim was also limited (if that’s what it was called back then). Both had “leather”, JBL, and were fwd.
Yeah. I mean I definitely like the car, and it unquestionably looks better than the last gen. Just wish I could get 49+mpg without caring how I drive like I did in my Gen4. It’s still more fuel efficient than the Tacoma my son stole from me, so it’s still a good option, I’m just not sure it’s a good enough efficiency for me to have not looked at other vehicles (hybrid or not).
The EPA tests are done with what would be about 4000 miles of wear on the tires. You should see some improvement with more miles racked up. Then the gen5 has worse aero drag than the gen4. Its effect at interstate speeds will be greater. However, you aren't far off from what Gerdes got in steady state testing.

Do you have the 19 inch tires? My gen 5 gets about 2 less MPG on average then my gen 4 did, but I think it is primarily due to the 19 inch tires. I go out of my way to avoid 70+ on the highway because that is not what the Prius is good at. But I just did a 'rush' 350 mile drive down to Miami, mostly 75-80, and I got just about 45 MPG. vs getting around 60 MPG on my local drives in the Miami area last 2 days, including a road trip to Key Largo. That's the kind of stuff the Prius is very good at. Side note - what bothers me the most about my Gen 5 is that it goes into regen mode way more often and seemingly unnecessarily then my Gen 4. I find myself using the EV button more when I'm in a parking lot, the car is warm, and I know it shouldn't start to regen.
