Real world 85D range - Better over time?

Real world 85D range - Better over time?

I had seen earlier posts saying that the 85D would likely get 34 more miles on the highway than a S85. I heard others speculate it was more like 10.

It looks like the EPA came out with numbers and now the combined difference is only 5. (Although the highway delta is 19)

My owner advisor said that range is really a function of battery capacity and not to expect for the the "D" to change. I am sure that is mostly true but I watched Elon talk about switching motors on and off to really maximize efficiency so software seems like it belongs in the equation as well

Is it possible Tesla writes a better torque sleep algorithms(or other code) that increase the mileage over time for the "D."

I only have 2 more days to confirm my order and thinking of skipping the "D" and saving $5,000.

If you are getting the D primarily for range than I would totally skip it. However if you live in a cold weather climate I can tell you first hand the D is a beast in the snow. We just received a fresh 6 inches last night in CT and I was driving all over to test the handling. No need for snow tires with the D which also saves money.

@tmaz - I'm in CT too and have been wondering all winter how it will do in the snow. My 85D is supposed to arrive "late March" so I'll (probably, hopefully) have to wait until next year to find out. Glad to hear you don't need snows. Are you using the stock tires or did you get something else?

Really the D is good enough to get you through 6 inch snow on summer / all season tyres?

@gbm. I'm using the stock all seasons. the only slippage i experienced was making right angle turns (e.g., left or right turns onto a perpendicular road). the back end slightly kicked out during acelleration, but quickly (within a second or two)recovered to where it was no big deal. Otherwise, the car had no problem taking off on completely covered roadways and unplowed parking lots (had to stop at Arbys after the gym). Snow's probably would have further mitigated the slight slippage, but the care almost instantly recovered as you propelled through the turn, so I really cant see wasting the money on snows. Bottom line, the car is a TANK and equally as good as my two x drive 5 series I owned previously, which, mind you were better in the snow than any of the SUVs I've ever owned. I recommend driving the car first with the all seasons and if for some reason you feel you need the snows you can buy them at a later point. BTW - if you get snows, buy a true snow tire like the Nokian R-2. I would not buy the ones on Tesla's website. While they provide a noticable difference for the RWD 85s, they are a performance snow tire and will provide only a slightly marginal improvement on the 85D.

Ah one thing I left off - I have the coil suspension and had no problem propelling up my driveway with 6 in of snow and a 30-40% slope. The reason I say this is because the air suspension is not necessary in order to drive in a fair amount of snow. Don't get mre wrong, if we get two feet, the car is probably not going to plow through it, but I would say that this would be true with or without the air suspension given that it only raises the car an inch higher than the coils.

Thanks so much. Great information. My driveway is similar (slopes down toward the house). I went with the coils, too. I figured if it's over 6" in the driveway, my wife takes the day off and I take the X5.

the car will plow through powder. If its six inches of ice, we'll all have bigger problems than just trying to get to work :)
