I recently upgraded my 2012 P85 (which FWIW was almost totally problem free) to the 2015 90D. I have reported to Tesla problems associated with GPS and SiruisXM on my car some of which I believe are potential safety hazards. My local service center has confirmed that the connectivity issues I...

Yes that would be a really good stop for me. I will be driving down in the next 3 weeks I think.. Can you PM me contact info?

Anyone who has an 80A HPWC who would be willing to allow me to use it on my monthly trips down through Southern Illinois, Eastern Missouri and ending in West Tennessee please let me know! I have two campsites along the way I have been using (one in Effingham, the other in Paducah) for 50A...

Tesla **is** up against a huge entrenched oil and auto industry even broader than what you pointed out. There is big oil, big automakers, and dealers. There are also gas stations, auto parts stores, auto repair, farming!? (ethanol), oil pipelines, oil shipping and refineries, energy trading...

If I start the car up from the app to let it warm up before unplugging from the charger, could I avoid the 10Kw loss?

We had our first (extremely light, melting) snow of the season here in Chicago today, and I was a little shocked when on a 7 mile drive my average wh/mile read 703!!!?? Temperature was not terrible, around 32F. Wind was light. Rain turning into snow. I had interior temp set at 70F, and I...

Ugh this is about the worst news I have seen, far worse than a couple of fires. I thought Tesla had announced a battery warranty that would allow you to "pre-purchase" a new battery for around $12K? Is that officially retracted now, does anyone know? Going to be going over those speed bumps...

I posted these "statistics" over on the Tesla Motors forum, but it might be worthwhile to recap here since my statistics actually suggest (but don't prove) that 2 fires is not unusual relatively speaking (even disregarding the point made earlier about whether 2 incidents is enough to make a...

This doesn't really detract from your point, but I think the correct number is more like 122 fires per day, on average. http://www.usfa.fema.gov/downloads/pdf/statistics/v13i11.pdf (three year period of 194,000 all-vehicle fires x 68.9% of those being "standard passenger vehicles" = total...

I think I have the lowest insurance cost with GEICO of any Tesla P85 owner I have found, and I am in a pretty expensive market (middle of the city in Chicago). It matters most of course if you have no accidents, perfect driving record, etc... but I pay only ~400 per 6 months with GEICO. That...

This could be an important story for us in Chicagoland... The 350 Green chargers that were at issue include a good number of CHAdeMO DC Level 3 chargers that can charge at a rate of 100 miles/hour. I believe there are 4 in the Chicagoland area located in the toll plazas... As Tesla has...

I don't have a problem with Tesla keeping an emergency reserve hidden so long as it starts and remains hidden. Like investors, distance driving in an EV absolutely requires predictability, especially when you are in the midwest where there is only one supercharger within in the entire 12 state...

In the spreadsheet I linked to above (from the EPA), go to the EV tab, and look at row 10 (row 9 is gasoline equivalent; row 10 is in 100 wh/mile format so more useful for us), and look at columns M, N and O - these are the "unadjusted" consumption numbers (in 100 wh/mile increments). These...

You are looking in the wrong tab... the tabs are "FEGuide" which only covers ICE, "PHEVs" which are hybrids, and "EVs" which are our cars.

Well, maybe. The EPA has an unadjusted number too - 30.2 Kw/100 miles. The unadjusted number is supposed to reflect driving without any such losses (ac off, no wind, etc.) on a dynometer. However, at 30.2 Kw/100 miles the 82.95 Kwh battery should yield an "unadjusted" rating of 274.67 rated...

I think our 85Kwh batteries are actually 82.95 Kwh. That might make the difference in calculating the "zero" point. See http://www.fueleconomy.gov/feg/epadata/12data.zip and look at columns CP and CQ in the spreadsheet: 350 volts * 237 amp-hours = 82.95 Kwh (I think). With no reserve...

According to the EPA, the Tesla S is rated for 265 miles range (85Kwh battery). However, the same EPA sticker info says that Model S consumes 38 KwH/100 miles of driving (average city and highway), which seems high but is obviously based on some testing methodology that must build in AC...

I edited my post above to provide for a series of tests that we can do. I think it would be really helpful to eliminate (or at least isolate) the variables #1-4. If we have enough people doing these tests, we should be able to figure out roughly what is going on. My money is on variance in...

I am not satisfied with using the modeled 267 wh/mile - it is a kludge and I think that the problem lies in our "acceptance" of that as a means to explain anything. The 267 wh/mile solution is just a matter of trying to fit confusing data to a linear equation - the lost 40 wh/mile is assumed to...

Same issue here ... reported to Tesla yesterday with log data. Will see what they say. The tech did tell me that the "reserve" is 5%. So assuming a full 85 Kwh battery, there would be a 4.25 Kwh reserve. Based on the information in this thread, I am assuming that the reserve IS included in...

The evtripper is awesome. It is exactly what I needed but did not have; i have it bookmarked on the Tesla now. My sincere appreciate and thanks to whomever wrote and provided that. Actual numbers from my trip (including the slight detour for charging) [FOR CLARITY, by "actual" I mean "as...

Well, I added 90 minutes of charging at 40 amps. The actual trip was 268 so I thought that by adding a 90 minute charge I would be pretty safe to drive "normally" and not have to hypermile. Now that I have seen the energy vs speed vs temp/Ac usage graph, I know my mistake. But the car should...

No issue here .. I think it was a bit off topic but I actually did not think about watching the speedo instant wh/mile readout and keeping that within 20-40 was a good rule of thumb I would not have known. ... I DID watch (religiously) the average energy readout, switching often between 5 mile...

Hmm.. This http://www.teslamotorsclub.com/showthread.php/13220-Putting-some-numbers-on-the-factors-that-affect-range explains my 42 miles of loss pretty much. 6% because of my 21 inch tires, and 12% due to traveling at 70mph for the first half of the trip... equals almost exactly the loss...

There is simply no way to do that driving 70 mph on a freeway... even on a straight away with no hills, no one pulling out in front of me, no passing, and on cruise control the average wh/mile never went below 325 - there isn't any technique to driving a single speed on a straight away!? I can...

Yes I know that now! I thought the "ideal" range of 300 was reduced to 270 to yield a practical range; but I know now that is fictitious too. I found the following on Tesla's forum - it seems the data already exists to adjust the rated range by temperature and speed at the least... it makes...

Just finished my first road trip - which was a 268 mile nail biter between Chicago and Detroit. Theoretically, I should have been able to make the trip without charging at the rated 270 mile range. But, I wanted a margin of safety so I borrowed a privately owned wall powered charger halfway to...

I live in Chicago and have a lovely new P85... and I can tell you that we really need ChaDEMO adapters here. The newly installed supercharger in Normal, IL is useless unless I am travelling to St. Louis. Western Michigan is slated for superchargers in the next 6-12 months, but not Detroit...

Chicago, IL P85 In Chicago, IL P85 with 21" wheels (stock) 1118 miles 357 avg Wh/mile (only June and July of 2013)

My two cents on the center consoles... I do think this is the most promising design so far but like others I am not going to pay much for a cup holder no matter how well designed. +1 for the USB ports though, good idea FWIW, here is what I *would* pay $1000 for in a center console to maybe...
