What was your the most efficient wattage

[GtiMart]

Just to clarify, round trip does not eliminate elevation changes, but it does help equalize a bit. Regen is not 100% efficient, I think it's closer to 80%, so you cannot reclaim all that you lost going up. Maybe if the slopes are low and regen doesn't play a role it's close but for big slopes there will still be a difference. For wind, assuming it doesn't change during your round trip, it's eliminated.

This is only true for a perfectly head-on wind one way and a perfect tailwind on the way back.
For every side-wind component there is a penalty.

This is correct but between the excellent regen and the underlying consumption of ~ 200 - 250 Wh/mile the 'flattening effect' of a Tesla driving in hilly/mountain country compared to most other EVS, let alone an ICE, is super impressive.

A few weeks ago I drove up the mountain near me. It is about a 4000 foot elevation change each way and the total drive about 70 miles. I averaged 185 Wh/mile.

Unless you are talking about round trip, as demonstrated by others in this thread, this number is fairly meaningless. People at elevation can get negative usage numbers going down the hill, and if they live in on a mountain / etc, could drive quote some distance doing so. Of course, that all reverses when going back up the hill.

TL ; DR -- roundtrip numbers only to compare.

It is round trip. I sure I would not mention one way trip. Trip to philly and back

What was your average speed on this 45 mile trip?

I did not go above 70. On highway it was between 60-67. I don’t remember exactly, but I think average highway plus city was about 55. I do this trip regularly, will try to get the same wattage consumption next week with details and screenshots.

You mean energy

You mean energy

Wattage, or more correct - watt hour or watt mile for cars since rate of consumption is not static is the unit of energy

watt is not a unit of energy, it is a unit of power
watt*mile has no meaning

watt*hour IS a unit of energy

Man, watt mile is short from watt hour per mile. And it is unit of energy.

I suggest you stick with the units used throughout the world instead of making up your own.

250 wh/mi on a downhill.

fyi, i stole this car.

I am not going to explain unit details, everyone understands the reference.

Since you do not understand units, I'm hard pressed to take your word about everybody.
If you cannot grasp the basics, you can just copy others.

Wh/mile

Today I had my best which was 178 wh/ml over a short 54 mile roundtrip with mixed speeds ranging from 30-60mph with the AC on low. When I returned home it only took 37m of range for the trip, I'm impressed!

Just took a trip after having the Unplugged Performance efficiency package installed - front lip & rear spoilers. Plus their anti-sway bars.
