M3 performance lifetime average Wh per mile

[Apprunner]

Do I still have the record for "best" efficiency? I'm slacking, having slid below the 500's which is embarrassing.

Finally...someone who's driving the car right!

getting about 10k out of a set of tires?

Sounds about right.
I'm on my 3rd set of summers, 2nd set of winters, @58K miles.
Switched to 265/35-19s, home they last a tad longer.

Well my 2020 3 LR AWD lifetime is 254. I checked a section
where were running about 82mph and we hit 278.
This was on new all season tires, I guess to get to 500
we would be in 160mph range.

You and I are probably polar opposites as I am at about 267 wh/mi after almost 5 years and about 96,000 miles. Still on my second set of Michelin summer 20s.

Oops, did not read performance here, sorry.
Why do I get the feeling that the older cars have
better Wh/mile. Why is my GOM (guess O meter) very close.
Why do I love the word Lambo.
Why is the sky blue, again sorry.
Never mind.
I thought I would save the Mod to parse the data,
it says that the 2020 is the best, however we have no
idea what crazy's are doing with the cars, including me.

Drag is the square of velocity.

Simple physics says that if 82 MPH is 278wh/mi, then 500 wh/mi would be at 110 MPH.

However, your numbers make no sense. If 82 MPH is 278, then 55 MPH is 125 wh/mi. Yet the car is rated around 220 wh/mi at 55 MPH. There is zero way a Model 3 at 82 MPH only uses 278 wh/mi on a flat road. Tesla's own numbers would suggest 82 MPH is about 400 wh/mi, and this aligns with my experience.

Why do I get the feeling that the older cars have better Wh/mile.

My car is a 2018. Older cars are much worse if you live somewhere that needs heat. I can easily have a short drive be 1kWh/mi if I only drive a few miles and it's cold out and the car is heating the whole time.

I've done numerous trips like the I5 trip up and down California in a Model 3 and Y. I'm skeptical that 82 mph is 400 wh/mi. Its about 320-340 wh/mi in my Model 3 Performance at 80-85mph on PS4S tires. I've done the LA to San Diego trips dozens of times at night and usually go about 85mph the whole way and always end up around 320-340 wh/mi each way (and its pretty flat).

That's fair as not all of the drag on the electrical system is aero drag. There are hotel loads, climate control, and rolling resistance that do not square like air drag. Some actually get better the faster you go since you spend less time in the car.

But there is zero way 82 MPH is 278 wh/mi when the car is rated 220 at 55MPH. Physics just doesn't allow that.

Personally, I use more like 375 wh/mi at 80 MPH in my older car if I need any kind of heating or cooling at all (stock 20" tires/wheels).

Agree. 278 wh/mi is like 70mph consistently.

Damn! Sounds like a blast haha.

I daily and road-trip with mine which dilutes the fun times a bit . Still, I am down to about 335 total after 28k miles in 16 months. The flush 275s and deck-mounted wing don’t help…

To add a slightly different take to this poll to this thread here is the photo I used for my One Year Anniversary thread I posted on Aug 25th of my lifetime stats on our 2022 MYP.

The only difference is I dumped the 21" UTs for some 18s from TSportLine. More efficient and faster. WINNER WINNER CHICKEN DINNER
