“Real Range”

[LightningShow]

No true. Consumer Reports just tested.

Dang, i know Tesla has a reputation for overestimating range but 20% under EPA in good conditions is pretty bad.

We're at 422 miles with our ER Lariat and we're at 322 Miles at 100% Charge. 130 Miles of 75 MPH on Highway and than 21 miles Towing dump trailer and small tractor/bucket/backhoe.
Almost one month since we bought Gas and we are impressed with the trucks ride, handling, towing, and comfort. Range seems pretty good with 100% prepaid energy in the form of our Solar Energy System.

Check your math. 322 miles at 100%, not 422.

Yes, thanks, I was correcting our Odometer and changed the wrong number!

The change in battery capacity itself is more than 10%.

This is interesting. I always thought the ideal battery temp was 21.5C. This chart shows 40C as providing the most capacity. Do EVs have the best range in very hot climates?

I think battery manufacturers choose a standard temperature at which the battery is rated. I’ve seen both 25C and 70F (21.5C) stated. It doesn’t necessarily correspond to the battery’s maximum capacity.
I‘d say the answer to your question is that max battery capacity may not correspond to max range, due to energy used for cooling the battery and air conditioning.
Remember that the battery will be running hotter than ambient. The battery may be running at 40C when the ambient is 30C, for example.

I had an “aggressive” 90mile drive this weekend. 75-85 MPH. Good weather, no ac or heat. My trip usage was 1.7m/kwh… That sound right? Has anyone done a chart showing usage rates vs/ MPH? (I have a platinum ER). Thanks

Speed is definitely a factor in miles per kwh. For at least two reasons not only are you getting to your destination sooner but in doing so you've created more wind resistance which is EV'S biggest range killer.
