Is my XLE 2023 MPG normal ?

No, OP's EPA values are correct.

 

For some reason, I thought the OP had an AWD version so my bad.

they said at 75 mph with the limited, they averaged 49 mpg on cruise control over 200 miles with no traffic

can anyone confirm or deny this number at a steady state speed?

Temperature, topography, technique, and speed.

You will get the best MPG's in mild temps (no heat/ac), over longer trips, on flat roads, at moderate-low speeds.

The big variable you can control is technique (ie. accel/decel, gliding/coasting, anticipation).

 

I have a 2023 Prius LE purchase August 16th. Currently have about 2300 mile. I live in the North County in the Florida panhandle. About 120 miles were on the interstate driving between 70 and 80 mph just playing around to see how the car handled speed..(it is a delight)...the remaining time is mostly spent driving at 55 to 60 with the cruise control on..limited time spent in stop and go traffic. Temps have been running from hot and dry August through September with temps currently between mid 30's this morning, warming to 50's 60's range.
Average mpg's since new 62.1.. I am a happy camper.. This is my second Prius.

 

Here are two cent comments
.
1) Tire pressure can be a factor.
Many bump up one or two psi, yet a pyrometer seems to be a foreign tool to many.
Note a high-quality air pressure gauge can be an asset.
A gauge that reads in 1/2 pound or 1/10 of a pound.
2) Wheel alignment could also be a factor.
Again a pyrometer in addition to one's eyesight can help with analysis.
Note appears the car is new, but there are assembly tolerances.
OP's warranty may cover alignments for the first year, otherwise, the hundred plus dollar alignment cost will offset any fuel savings cost.
3) Winter fuel blends typically give lower mileage than summer blends.
4) Yep, use of heater seems to affect mileage.
5) And yep, you still need to use the "go pedal" for acceleration; on-ramp merging and lane changes.

With that said...... check the tire pressure

 

I would love to get those type of miles, I live in S. Florida so there is no mountains or hills . Even when I try to go easy on the pedal I still get crappy MPG average , This is not my first Prius, I had a 2010 14 years later I traded for the xle.

 

Turning on ECO mode, my MPG went up from high 40s to 50+ even in hot summer similar to Florida climate.
It should add 2-3MPG the main difference is the AC doesn't blow as cold at first, if you can deal with that.
The weather has a lot to do with it.

 

55-60 MPH is the optimal driving speed for fuel efficiency. Anything past that and your mpg starts getting dinged pretty significantly.
Mpg For Speed - Fuel Efficiency Vs. Speed

Wired did a cool write up comparing this with time lost during a commute vs. money you could be making at work during that time.

"Most cars" means traditional gassers, not hybrids and EVs. After seeing previous Department of Energy figures on mpg vs speed, which I believe was tested before the hybrid era, I don't agree that the people making this "55 to 60 mph" claim are interpreting that DOE data correctly, it was for a different purpose. And from direct personal experience, I know quite well that Prius speeds in the low to mid 40s produce higher MPGs than 55-60.

Previous Prius MPG vs Speed tests and mathematical modeling among enthusiasts here and in Japan, specifically on Gen3 and earlier Prius generations, have produced several answers for Prius Peak MPG:

* under 25 mph, from a member here who tested and plotted MPG for speeds 25-80 mph. Unfortunately, the chart in his original post has been lost to repeated PriusChat host migrations (many broken links and lost images), though might still exist from being copied to other posts years later. Wayne Gerdes over at CleanMPG has similar charts, though I don't remember his testing below about 40 mph.

* about 15 mph, according to one group of test-and-model fans;

* between 10 and 20 mph, according to another group of test-and-model fans on the opposite side of the Pacific.

If your time is unconstrained such that you can drive slow, your Prius can deliver over 100 mpg.

Combined with the value of the driver's time, all this means that the Prius' "optimal driving speed for fuel efficiency" is "the lowest speed the driver can otherwise accept or tolerate, or ~15 mph, whichever is higher".

 

So what you're saying is if you're stuck in traffic and crawling along, at leas you can feel good about the fact that you're basically sipping on an itty bitty teacup of gas and its almost free to drive!
