300 Mile Range Specification

[NealC]

What speed, temperature, altitude, etc. is used to specify the 300 mile range?

The reason I ask is because drag increases with velocity squared and I am getting 335 Wh/mile for my normal drive around town (over the last 9000 miles). I've only once took it on a trip where the speeds were around 75-80 mph and I was using around 450 Wh/mile. If you ever get in trouble getting to your charging station, reducing the speed just a little should significantly increase range.

AFAIK, they use the EPA 5 cycle test.

Thanks for the information. They sure made that as complicated as one could get!

I regularly get 300 miles to a full charge. I don’t drive very fast though, so that probably figures in. My overall usage for 26k miles over the year+ is about 340 Wh/mi

My lifetime is 420Wh/mi

I drive it like I stole it

Speed kills, especially range. I suspect they are projecting using the speed limit and mixed city/hwy driving. 335 Wh/m should get you more than the projected range, that is really low! Highway speeds get less range than in town.

They are the government, and they are here to help you (complicate everything).

Iv driven 20k on interstate. I never get more than 175 miles off 300 charge.
The it was new I only got 225.
Iv got 230k on my S. It gets about 200

Do you drive 90 mph on the interstate? Those numbers don't seem reasonable compared to what I'm experiencing.

Designed to go 420miles at 69 MPH.

Actually that’s a little generous.

Agreed! Drive the thing and enjoy it.

master understanding and using the in vehicle energy app
just drive in all conditions attempting to maintain the desired wh/mile desired
the 123kwh pack at 95% max utilization, 300 mile range target requires you maintain max 389 wh/mi
for the MYP, that meant driving in perfect weather, 68 miles per hour, no more
but its amazing how much all conditions affect the wh/mi
we know temp, humidity, wind, rain, hills up or down, etc
but the road surface has a massive impact
just returned from a 1250 mile drive, one interstate normal smooth at the desired wh/mi, all of sudden in another state, same interstate, designed very rough road surface and my wh/mi climbed hitting range bad
back to the smooth surface and my wh/mi dropped
point is, the energy app is king, live by it for max range

This would be a brilliant metric of measurements for EV brands to strive for lmao!

This is actually what makes Tesla the only mega success so far in the EV world. They have massive data sets, and also don't shy away from building in professional tool sets for the public to use.

Most of the time when I try to explain this stuff to the average ICE driver, I get the "deer in the headlights" look.
