Hi all,
before I paid extra $10,000 to upgrade from 75D to 90D. Just 1 hour ago 100D is available, only $3000 more! But the range increased by 38 miles! That make my 75D -> 90D upgrade like an idiot!! My car is not under production yet, just have the VIN number. What should I do? Ask the sales to change it? Is the extra $500 worth it? How long will the delay be (it was said to be there by Feb 16).
YES, it is most definitely worth it. Especially if you already upgraded to a 90D.
I did some calculations, but I don't have Model X 60D to 75D numbers; so I'm using the Model S.
Old Pricing Model S 60D to 75D: $9000 for 37 mi. ($243.24/mi)
New Pricing Model S 60D to 75D: $7000 for 37 mi. ($189,19/mi)
Model X 75D to 90D: $10,000 for 20 mi. ($500/mi + Performance Increase)
Model X 90D to 100D: $3,000 for 38 mi. ($78.95/mi)
Model X 75D to 100D: $13,000 for 58 mi. ($224.14/mi + Performance Increase)
Without getting into the software, charging at 100% discussion. The 75D to 100D is already a pretty good deal if you can afford it. Going from a 90 to 100, is a screaming deal. Even if you have to pay the $500.
Thinking about it another way. If Tesla gave you the option to downgrade back down to a 75D but keep the 90D performance, and refund you $2,000 (78.95/mi x 20 mi + $500 Change Fee) Would you do it? If yes, the upgrade may not be for you. If your answer is **** no! Then you should probably upgrade. If you needed to check your wallet, bank account, and/or credit report. I can't help you.
I have 2 X 90Ds on order
My questions are:
1. Are these 90Ds actually 100D packs?
2. Can I upgrade to 100D now and not lose free Supercharging?
3. Can I upgrade to 100D later and continue to supercharge for free for life?
1. No, they're not. There's been a couple of articles about upgrading from a 90D to 100D. It involves a battery pack swap. Here's
one article.
2. There's been a claim or two that it was done, but during the confirmation period and not during the change period. Nothing has been confirmed.
3. Unknown, based on Tesla's statements; you should be able to. The supercharging for life is tied to the VIN of the car. If you upgrade and do a hardware battery swap, you would retain your VIN and thus your supercharging. But refer to #1, it's $20,000; vs upgrading now would be a $3,000 additional plus $500 in change fee. The difference is $16,500 for free supercharging.
$16,500 will buy you 82,500 kwh @ $0.20/kwh. If my math is right (it often isn't) that's an estimated 275,000 miles at 300 wh/mi on the supercharging network to break even.
The only way #3 would make sense is if you need a replacement battery pack anyway. But you're looking at a failure that would be out of warranty, which would be 8 years down the road; and kind of makes this discussion a moot point as we will be talking about another battery by then.
