Question-2025 Prius in EV Mode: Reply quickly!

I have grown to love how they look. I guess I want efficiency and good looks. A small sacrifice. I’m not quite as serious about saving energy as I thought.

When I drive, though, I’m back to my old driving habits of driving for efficiency. Now that I have a car that can report EV efficiency directly, I’m trying to do my best there (as I used to be for gas mileage).

 

What do you guys have your tire pressures set at? In the app, mine measure 44psi in the back and 45psi and 46psi in the front. That seems rather high, doesn’t it?

 

I went out for an EV drive tonight (just for the sake of measuring efficiency). I drove on roads with about 55mph speed limits yet with many stop lights (1/4 mile apart). Overall, without the a/c on, I got about 5.0 miles/kWh. I know I could have done better if it weren’t for those stupid stop lights. When the upcoming light was red, I tried to coast in to maintain kinetic energy.

As expected, this isn’t as good as other people have reported. I guess that’s the penalty for buying the upper trim with all of the bells and whistles.

I’ll be taking the first trip to work tomorrow when the stop lights are further part (but with higher speeds of 65mph…I may not drive that fast, though).

 

The dealer who sold me the car never asked me what I wanted. I think I would have asked for something similar, though. I think they must have been very helpful in allowing me to get 56mpg (after EV was gone) on the trip from Milwaukee to Minneapolis (at speeds of 65mph to 70mph).

I’ve never driven a car with the thinner tires on larger wheels. I just assumed that they were supposed to be set to the higher psi values.

 

Quick question: Do you open the windows to keep it from getting so hot on the inside? I’m worried about overheating the EV battery.

 

I guess until I hear differently, I’m going to be cracking my windows open so the EV battery doesn’t get as hot.

 

Yes. I just measured the tire pressure with an accurate gauge. They are correct 45’s in front a little less in back. That’s exactly what I’d want to help improve efficiency!

When my wife got her Rav4 hybrid, her tires were also pumped up rather high

 

Yesterday, driving about 55mph, I was to get to work (21 miles) and back with 15% of the battery remaining. I ended up having a 4.4 miles/kWh efficiency.

Today I’m driving at 60mph. I’ll see if I get home without gas.

Hey, does anyone have Toyota app working correctly? Mine (iPhone) never shows my correct current charge levels. I also wish it would update solar roof statistics.

 

Yesterday, it was cooler and I wanted to see how efficient I could drive the car, without a/c in (EV mode): The result, was 6.4 miles/kW-hr (over about 15 miles drive).

I was hoping to see 7.0 miles/kW-hr at some point but I never got there. It’s funny. I used to think that once I got an electric car, I’d no longer care about efficiency but I still do. It is electrical efficiency rather than gas efficiency that matters to me (and, thus, I still drive slow).

 

That is very interesting! I never thought of it from standpoint. Certainly my numbers weren’t influenced by that as I started and stopped at the same place. I shall try that out sometime!

 

Why is the newer generation not as efficient? It seems strange that they would go backwards.
