What's your lifetime Wh/mi?

[Darthamerica]

This includes a road trip from Los Angeles to New Orleans and back where speed limits are as high as 80 MPH through Texas! Temps between AZ and Texas were as high as 112° and HVAC is always running at 68°-72°. Sentry Mode is always on for me.

After ~9k miles - ~450 wh/m

 

[MetalBonsai]

368 Wh/mi over 1986 miles.

This is with a trip from Seattle to Vancouver B.C. and back. Mix of freeway and local, not going much over 10 mph of speed limit.

Also: AWD, no aero covers, usually riding med or high.

Early days with about 1/3 highway. 343 Wh/mi. Summer in the Northeast, I expect this to get worse in the winter, how much is the question.

For reference, my Model S Plaid with 21's and winters (when appropriate) averaged 321 Wh/mi in a full year and 7,500+ miles before I sold it.

That the Cybertruck can come within spitting distance of one of the most aerodynamic vehicles on the road is astonishing.

I see you Reuters and Electrek, I guarantee you won't steal this post for an article because it's not negative about Tesla. Jokers.

PS I don't use Chill mode. Why would I do that in vehicles with this kind of power? I'm not afraid to use the power, safely, on roads.

Here are my totals for the last few months. My commute is relatively short and all backroads.

Not too shabby in here!

 

[Axwbw]

8900 miles, 433 wh/mi. Mostly commuting, but some towing, some haingsome sand, some off-roading.

Wow, lotta low numbers here. I’m at 386 Wh/mi and 2,216 miles and I thought I drove like grandma. I have one 800 mile road trip in there doing about 75 MPH. The rest is up and down my town. I say up and down because I live at the top of a hill, about 500’ elevation from town. I can actually get to many destinations with a negative Wh/mi, but the return trip is over 500 Wh/mi.

Just to show you how we think, when I first bought my M3, I was wondering if the hill would consume the battery, leaving me stranded half-way up the hill. Of course, the power has so much capacity, that is not an issue.

At 386 Wh/mi, it is equivalent to about 40 miles per gallon, cost wise, for me. Given the $0.32/kWh and $5/gallon for California gasoline, the math is $5/0.32/386*1000=40.5 MPG. Your equivalent MPG will depend on your local cost of gas and electricity. 40 MPG is pretty amazing!

Nice!

I have an excellent use case for range. Most of my miles are on rural roads with 50 - 60 mph speed limits. 650 miles of interstate highway at 70 mph. 80 miles pulling 1,700 lbs tent trailer. Temperatures are hot here in Texas. Tires at 50 psi cold. Very pleased with range! AWD no aero, AT tires.

I was using TeslaFi and it was showing a lifetime average of 369Wh/mi. I went into the settings and used the modification factor (1.067) to make it match my vehicle lifetime average reading. The adjusted speed and temperature efficiency stats from TeslaFi are show below (extremely small datasets still)

I drive mostly backroads, tire PSI between 49-52, tonneau cover closed, custom setting (regular, relaxed, higher), 70 degrees cabin temp w/max seat cooling, 100 degree overheat protection and sentry mode always on, TeslaFi polling and added Tessie now too.

I also exported the TeslaFi data to Tessie and they are showing a lifetime average of 423Wh/mi. Maybe Tessie is estimating for home charging loss and Tesla/TeslaFi are not. ?‍

One missing piece is I found the wh/mi does not include power consumed while car is idle, such as sentry mode or AC on while idle, In hot summer Texas, driving only consumes ~63% of the total power I charged. In ny case, the real MPG need to multiply by 0.63.

Using the same formula here in Washington, with $4 gas and $0.10 electricity, 386 Wh/mi is over 100 MPG!

My lifetime average has crept up to 399 Wh/mi due to all the off-roading where I tend to consume 420 Wh/mile. That works out to 95 MPG when off-roading! In my F-150 I would be lucky to get 10 MPG on the same routes.

You must not drive very many miles per month. The ICE equivalent would be if you left your engine idling while at work to keep your air conditioning and dashcam running for sentry mode. But ICE cars don't even have Sentry Mode and it's impractical (and perhaps illegal) to leave your engine running to keep the cabin cool when you are away from the car. Instead, you park your car with a hot engine and then that engine heat soaks through the firewall into your cabin, making it even hotter than an EV without Cabin Overheat Protection.

If you don't like the extra consumption of Sentry Mode and Cabin Overheat Protection, then you always have the option of disabling them.
