Energy Consumption On Model 3?

[T34ME]

Do we have already some data facts from early adopters about consumption?

Realistically, the numbers are all over the place depending on speed, 19" wheels vs.18" wheels, aero covers or no aero covers, climate, elev. change, etc.

My opinion is the number is around 255 to 265 Wh/mi at 70/75 mph, flat land, mild climate, no wind with 18" wheels and aero covers. Maybe 265 to 280 Wh/mi under same conditions with 19" Sportwheels. YMMV.

I get 270Wh/mi @75mph in my P85.. I would hope that the Model 3 is more efficient than that.

An Electrek article from July noted that the Tesla website briefly contained reference to the Model 3 efficiency in the mileage estimator.

The efficiency rating was 237 wh/m, and I assume this is best case scenario (smaller battery and aero wheels).

That fits well with EPA range for the small battery. 52 kWh/220 miles = 237 Wh/mile

That would be the combined city + highway result.

Highway only at ~ 65 mph is 250 Wh/mile

Highway only at ~ 65 mph is 250 Wh/mile

No, it's definitely lower than that. The Bolt EV gets 250 Wh/mi at 65 mph, which I've verified through testing.

Here are my estimates for the Model 3.

Based on what?

 

[Zoomit]

Based on what?

Physics-based models using public specs and engineering estimates then calibrated with EPA submission data. No empirical Model 3 data yet.

220 Wh/mi @65 mph is pretty low. The lowest real world I've read about was 240 Wh/mi for an owner while commuting. Of course this wasn't cruising at steady hwy speed. All other Wh/mi at hwy speeds (75/80/90) were much higher than in your figure. I've seen 255-300 so your estimates seem pretty low to me. I'd love to see them in the real world, though.

EDIT: I looked at your graph in more detail and noticed the consumption Whs are going up fairly quickly with speed. So 220@65 might be realistic after all. Would be great!

Interesting, so steady 60mph would give 370 mile range?

Could you extend calculation till 100mph? For those who (sometimes) drive on the autobahn.

 

[Zoomit]

Yes a steady 60mph would be around 370-380 mi. The energy consumption goes up to ~390 Wh/mi at 100 mph according to my current model.

 

[ölbrenner]

Love the continued speculation, even as the real world numbers come in.

If your estimate for the Aero wheels is accurate, the Sport wheels will at least use 10+% more energy. Probably 15+% more since the EPA testing shows 10+% more at 50mph for the Sport wheels.

I’ll add my experience so far with 300 miles we averaged 300 Wh/Mile. 19 inch wheels.

Some cavities 1) Took an 80 mile round trip to SF late at night at ~80MPH. 2) Home is up hilll and every time we start our driving we get the “limited regen” all the way down the hill. Probably loosing some effiency there.

235/40/19 or 235/45/18?

and if 18", can we assume aero covers on?

You do realize you quoted dragoljub's 19" wheel size?

Yea 19 inch wheels.

We do not drive agressive but usually fast in car pool lane on freeways.

I think limited regen on our downhill is what’s to blame for my lower than expected efficiency. Will reset trip B for some fresh averages.

Does limited regen also occur when you start with less than 100% SoC ?

Did 120 mile round trip yesterday on Highway 1 from Aptos to north of Half Moon Bay (a pretty flat stretch of earth). Speed mostly 60-70 except the last bit of highway 1 where it was probably 75. Outside temp 60-65F. Averaged between 220-230 Wh/mi. The battery range indicator was spot on. Aero wheels.
