    Coldest (and I use the term loosely) drive so far in either the Prime or the "Not the Prime." The car showed 37º when we left the farm. Here's what it showed when we got to the store. It was actually over 60 mpg a little earlier but we had to stop for a traffic light and didn't get a chance to recover before we got to the store.

    That's really good for those temps.

    I thought so. These are slightly rolling hills and rural roads, driven at around 45 mph, so that really helps with fuel economy. And with the engine coolant piped through the cat and the active grill shutters, it's incredible how quickly the ICE will shut itself off. One morning, at around 45-50F, it went EV in 1.0 miles.

    Is this with the heat on? The regular Gene4 doesn't have the heat pump, which must have affected the mpg negatively. I think PP can get over 60mpg at that emp on HV mode even with heat on.

    78 degrees.:eek: I would be sweating to death at that temp. :LOL:I don't usually use heat in my car until the ambient temp is below freezing. Even at below freezing, I have never set my temp above 70F.

    That's about what I would do if I was alone. I'm pretty flexible for temperatures. Wife likes it cool now that one of her meds has apparently skewed her thermostat. She used to always be cold. Now, I hear 10 times a day, "I'm sweating!" LOL! Mother-in-law likes it miserable warm. We love her dearly, but we're doing some serious sweating in her house.

    Edit to add: Oops! I was a little high on where we had the HVAC set. It was actually 77ºF.

    We topped off the gas tank this afternoon in Galion, OH so we can leave for West Branch, IA in the morning with a full tank. If I was willing to endure I-80/I-94 through Gary & Chicago areas, we could get there on one tank. But the plan is to go through Indianapolis on I-70 & get on I-74 to Iowa. So far, so cheap. Except that I just bought new wiper blades. The originals (I assume) were getting smeary and it looks like another day of drizzle tomorrow. I tried an auto parts store just to see that they had. First, they didn't know that Toyota makes the Prius. It's that bad here! And they only had one blade ... the passenger side, which is naturally NOT the one that's smeary. LOL! The Toyota dealer was nearby. While there, I noticed one Prius and two Rav4 Hybrids on the smallish new car lot. Anyway, the parts guy said you had to get a 5-pack to get just the inserts. In hind sight, I wonder if I should have done that since both our cars now take the same wiper blades and are the same model year. Oh well, what's $42 when I haven't spent much more than that on gas so far after 1,622 miles on the road. :LOL:

    Considering you did not stop to stay at a lodge in between, Yeah, if you don't mind driving, $60 for a 1600miles trip for two people is hard to beat. And knowing you are not sharing the air with strangers in a closed quarter, it is the best way to travel in the COVID era. Have a nice rest of the trip.

    Yep - better than cramped up in one of those flying tubes.

    Safe travels. Enjoyed the pics and the MPG calcs. About the same as my 16 if I could manage to keep it just 1-2 MPH over the speed limit. Speed kills MPG on our Prii's!

    Indeed it does. Here's the last fuel economy shot of the trip. I'll post real numbers later after we finish unpacking and all the other stuff that piles up when you take a trip.

    Here's the entire trip:

    And here's the last four days. Oct. 20 was the drive from Ohio to Iowa. Winds were not too contrary and even helped for a little while. It rained most of the morning, though.

    Oct. 21 was in West Branch. I don't think we drove more than about two miles at any one time and the temps were in the upper 30s to low 50s.

    Oct. 22 was West Branch, IA to Columbia, TN in rather contrary winds. And then the final day driving home with very little wind at all.

    The data is all complete. At least all the data that I'm interested in enough to collect and tabulate. I guess, considering that the vast majority of miles were at 70 mph or even a little over, I can't complain for a regular Prius with NiMH battery. There was one tank where I was sure it licked off early, so I gave it some more gas. And it was early again, but I didn't want to fight it and maybe over fill the tank. So I filled it again in West Branch and when combined, they came out OK.

    I'm not sure if a Li-ion would have performed any better but I suspect maybe 1 mpg. I'm sure the Prime would have been at least 4-5 mg better. There were several things I missed from my Prime on this trip, but I did appreciate the BSM and the greater cargo space with this car. Either car is a real treat to take on long trips. Comfortable, reasonably quiet, safe, and economical.

    That certainly beats the Gen 3 on highway trips so there's a definite improvement on the Gen 4 (for any Gen 2 or 3 owner considering on upgrading).

    Yes I believe the Prime will be at least 4-5mpg higher. And even higher still if you could get one or two charges during the trip at hotels or even a partial charge during meal time.

    Totally agree. Last year on our big trip in the Prime (6,013 miles) we got 56.6 for-real mpg with a lot of very high headwinds. (Going across IA into 50 mph winds, we only got 43 mpg.) Lots of rain on the trip, too. We got to plug in for day trips while visiting my sister in AZ and friends in CO. Otherwise, it was ICE all the way. Had the weather been more neutral, I think it would have been over 60 mpg in easily. Getting 60-75 mpg in the CO Rockies sure helped that average!

    The weather was a lot better this trip. Didn't rain as hard or as much. Winds were much less nasty.
