Some numbers on a trip I did today

[cinergi]

Figured more of this type of information will help future Model S owners ...

I drove 154 miles today (2 hours, 40 minutes). Used 38.9 kWh of battery (253 Wh/mi).
When I left, the Roadster indicated 189 Ideal Miles (IM) and 130 Estimated Miles (EM) (of range remaining). When I returned, I had 22 Ideal Miles and 19 Estimated Miles. This was all in standard mode. The first half (literally) of the trip, I drove 60-65 MPH to be safe on the range. When I came back, I knew I was doing OK so I drove 80 MPH as much as I could. This was with the top off and no HVAC, 80 degrees F ambient.

I "used" (189 - 22) 167 IM to go 154 actual miles. And a lot of that was well over 55 MPH. My 130 EM initial range was based on previous aggressive driving and using the A/C and so not terribly useful for the trip.

During the trip, I watched both IM and EM. After having driven 40 miles (that's what the EM is based off of -- your last 40 miles of driving) at 60-65 MPH, EM and IM were within 10% of each other, so I knew I was doing well. I knew if I continued driving like that, I'd have a total round-trip capacity of 170 miles (and I knew my trip about was 150). And guess what -- I had 20 miles left when I returned -- even after coming back at 80 MPH. And if something weird happened, I also knew I could go into range mode and "acquire" another 20-25 miles of range just in case.

Here's what shows up on the screen in the Roadster. The Model S stuff will likely be even more thorough.

Thanks for this. Hopefully the Model S computer is equally accurate -- and that we'll be seeing a lot of impressive real world numbers

I think it says a lot about the Roadster, and the confidence owners have in the IM and EM readings, that you'd do this trip in standard (not range) mode.

Thanks for the info. Most useful.

Thanks cinergi , that's some great info and exactly what I was looking for.

It wasn't today, it was late last year. But I got some pretty impressive numbers on a long drive last year:

.......and you took the picture with which hands????

The picture was taken by a cellphone in my left hand.

That was a trip from Redmond,Wa to Paradise, Mt. Rainier and back, a 192 mile roundtrip. Paradise is at 5400 feet.
That photo was taken during the descent.

For safety reasons, Model S should have a button on the touch screen "post screen shot of my trip counter to TMC, add location, elevation, and my favorite bragging line to it."

+1 ...

Sounds like a job for an app using the SDK!
