Is that referring to the black part of the pic below? Or the whole thing between the headlights (including the T logo)?More interestingly... (leak OP) claims the nose cone is gone.
Not quite. Likely, but not for certain. Doug didn't confirm that the request was from Tesla (vs a third-party that created the mount we think we saw), and even if it was, 'proprietary info' doesn't confirm everything (or anything specific) that we think we learned from the image.
I've been asked about X battery options and I'd like for everyone to get the answer.
The model X will have only 85 and 60 battery.
The form factor has changed slightly. Comparing to 2012-S, the batteries are roughly 20% better. However instead of putting more batteries in the car, the efficiency is used to take weight out. When you model battery size vs. range there is a point at which increasing battery size has diminishing returns (due to added weight). That point rests almost squarely at 85kwhr for the next 3 years. Current improvements in battery energy density are not best used to add more pack power, but to reduce the weight of the vehicle allowing longer range with the same 85kwhr pack.
X is slightly overweight as it stands now and every attempt is being made to save weight wherever possible. Considering it is a much larger car, the efficiency gains in batteries will show themselves when it achieves the same range as the S.

Likewise, it seems he knows no better than us whether there will be a 60kwh in the Model X, which ultimately seems unlikely at the time due to the lack of a S60D.
Going in this afternoon to have my BS detector cleaned and reconfigured...
Can you clarify this? Did you mean the following:
- The form factor DID NOT change, the cell is still 18650, i.e. 18mm in diameter, 65mm long
- Each cell is roughly the same weight, but holds 20% more energy
- The 85kWh variant therefore will have 20% less cells, may be 5,696 cells instead of 7104
- This saves at least 140 lbs from the battery pack (counting savings from the cells only, as the pack is probably changed little)
- The new battery DID NOT gain in "efficiency", but did gain in volumetric and weight energy density
Wondering the same!
With the S and X so similar in the skateboard I think we can be sure they'll stick to 18650. So the 20% reduction would likely result in identical packs as the S but them being 20% empty/ballast for the same capacity (60/85)? Huh, would be irritating to know your 85 could've been a 105 if just those holes in the pack below you were stuffed with cells. I know, he said the sweet spot for now is 85 but a 105 would still go further.
I am really curious if the OP responds because there are additional implications from this info. During the ER call Elon was adamant that 30% reduction in cost is due to improvement in manufacturing efficiency only. So if one applies an additional 20% savings due to quantity of cells, the total savings comes to whopping 44%. This could have a major implication for the gross margin trajectory for MX, MS and Model 3.
I believe you can't multiply the effects. I think he saying between the supply chain efficiency gains, the new cell form factor, and the new cell chemistry, a 30% reduction in cost.
Yes, to be precise about our prediction was that we felt comfortable with at least a 30% improvement in cost or reduction in cost just based on the location and economies of scale. That's without taking any technology improvements into account and we will certainly do technology improvements. If we can't get to 30% even without technology improvements, somebody should shoot us because that would be in complete defiance of economies of scale and obvious cost savings.
Check the Tesla Motors Model X page and they mention 60 and 85kWh in several places:

I'm not convinced based on this picture alone. There's a line going down the inside of the roof that appears to be perhaps a ribbon cable from the rear view mirror assembly on the windscreen to the aft of the forward compartment. I don't think Tesla would have a cable running down the middle of a sun roof, but you never know. However, I am in agreement that it looks [ahem.. looked!] like perhaps a roof rack assembly.
I have some problems with this line of reasoning. "Efficiency gains in batteries", what does that mean? What does "roughly 20% better" mean? 20% improvement in energy density? That would mean a bit over 100kWh pack would be possible for the same space and weight as the 85kWh pack, which would provide significant range increase. Since range is more important in steady state long distance driving than around town, and since aerodynamics are more important in steady state long distance driving than weight, I don't think a 20% reduction in pack weight would provide as much range as a 20% increase in pack capacity.
Thank goodness if it is !! That thing was the ugliest part of the Model S.
Sorry folks. Got a friendly request from Tesla to take it down as it's "proprietary info".
