Miles/Kwh

[Westchester Air]

You CAN be a person of two minds. I used to swap back and forth between a 2004 Prius and a 2007 Ferrari 430. I had no issue driving for range / efficiency in the Prius and then letting it rip in the Ferrari. One got over 40 MPG easily and the other? Sometimes under 10! Nowadays I have one car (my 25 AGT / 19”) that can do both!

Lifetime average through 2500 miles is 4.0. This past winter was in the 3.8 range, more recently I’ve had warm weather days in the 4.8 - 5.0 range. Very doable if you try! I actually find that I have just as much fun in my AGT driving it for range as I do wailing on it…it does both exceedingly well.

Completely agree!

Averaged low 3s on my morning commute yesterday (started off in the low 40s temp wise) and drove home in the afternoon in the high 50s and average high 4s LOL. Not "concerned" about efficiency, but curious as part of the journey of owning my first EV. The car is so fun to drive it's probably hard to meet EPA estimates...

I'm trying to think of luxury cars with bi-turbo V12s that make Lucid levels of power and torque

... where the owners are concerned about fuel efficiency ...

Two differences. Many owners will rarely take those vehicles on long trips. If they do range is rarely a concern. The choices of where to fuel are many and the complications with refueling are few.

For people collecting data: Air GT Sept. 2022 build. Use 19" A/S Nov.- Apr. / 21" Summer Apr. - Nov.

Lifetime average 3.3 mi / kWh

Have seen well into the 4s when wife is with me.

Sometimes a man needs to have sudden bursts of irrational acceleration and speed.

Sounds really boring!

Yeah, but I remember a video you made demonstrating that boring resulted in good numbers.
My lifetime is about 3.8, so this was a one off.

These are the stats I need....Miles/KwH driving with the wife vs. without the wife

 

[Blue Lectroid]

Yes, efficiency is highly fun pedal dependent!!

I was thinking the same. I have a Pure AWD with the 19s. Am in SF Bay Area so the winter temps aren't as low as the east coast. My lifetime is around 3.7 m/kwh. Highway driving is mostly in the 70-75 mph ran

I live in a temperate climate year round, and my Pure AWD average over 14k miles is also around 3.7 miles/kWh. No aero covers, but I drive pretty conservatively. I once did 4.25 miles/kWh from Cedar City Utah to Phoenix, but a lot of the drive was on slower rural roads, on a perfect day with calm winds, and with about a 4,800 foot elevation drop.

Montana here. Similar weather, similar results. However, I want to add that in-car heat makes a big difference. When in the teens, I drop below 2!!. At 50 degrees or so, I turn off heat and get up to 1.0 additional m/kwh. It’s a big difference. Also seat heater much more efficient than fan blowing heater. I wish you could just turn on fan with no heat but I cant figure out how to do that. you can turn off AC but I cant see how to turn off heat without turning off whole temperature system.

Hi! I think you can turn off the A/C, drop the temperature setting as low as it will go, and then manually adjust the blower speed and direction.

"They" have been de-constructing the intersection near my home for years. Now they have made a section of about 150 meters of the most pock-marked, bumpy, crack and hole- infested "temporary roadway", followed by the former smooth and straight "pike". After this bumpy section I make a Left into my neighborhood ~ 600 meters.

So my technique is to drive VERY slowly over the bumps, which annoys the SUV/Pickup drivers and makes them crowd my rear bumper. Then I "floor" it, to make a large gap so I can make the left turn without them crashing into me. This works very well, and it's fun to humiliate the "hemi" boys.

However. A few days ago I did this with the wife in the car. She says I almost broke her neck. I was in "Smooth" mode.

She has no idea.

Not a clue.

I love driving this car and routinely drive at 75 (indicated actual around 73) on the freeways. I also often drive in the coastal mountains on windy roads with elevation changes for fun. Have 20k miles on it and my average is right around 3.1 mi/kWh. Battery capacity according to the test app is around 90% so my maximum distance would be 329 miles (.9x118kWhx3.1). Is that bad; not really since on trips we usually stop after a few hours driving for a meal and charge back up while eating. I don't think I've ever seen my SOC below 30%.

 

[LuvLucy]

Sounds really boring!

Also, please, for all of humanity no hypermiling in the left lane!

 

[terrycs]

These hypermiling threads will start fading away in time ... after all, I don't really see any for the ICE versions of BMW, Porsche or MBZ.

If anything, we should be paying more attention to range when the battery is charged to 100%.

Yes and that was a horrible drive! It’s weird to be driving an 800+hp car while being passed by U-Haul trucks and semis. My lifetime efficiency is 3.08 over 35,000 miles.

 

[borski]

My lifetime efficiency is low. Just the way I like it.

My 25 AT 19" (though I have many fewer miles than most of you) is also 3.08. I don't drive too conservatively. The biggest hit for me is elevation. I live about 830' above sea level in a hilly area. If I drive down to the flat lands it's great, and then drive around it's still great (like in the 4's). Today I drove down, little freeway, and was in the 5's, then mid to high 4's. After I climbed the hill back home it was 3.4 for the 30 mile trip. I tried to be a bit more conservative today just to see what would happen (for quite a while it was 6.21 in the flats, apparently it never goes higher than that number). I don't like to be that conservative

Last time I drove up to SF it was 4.1 when I hit downtown area. But, every time i get back home it's in the mid to lower 3's. If I drive "normally" (for me), it's back down to low 3's. Going uphill you can watch the numbers drop rapidly (which is understandable as one moves 5,000 pounds up a steep hill). I don't care that much, but will be interested this May when I drive round trip to Palm Springs to see how it fares.
