Refreshed Tesla Model S

Just a couple of days ago, via a CARB leak, we were able to confirm that Tesla will be offering the Model S in 75D.

The 75D version adds 5 kWh over the existing 70D Model S and goes up to 259 miles on a single charge, according to Tesla. That’s 19 miles more then the existing 70D.

The extra 5 kWh is expected to set buyers back an additional $3,000 and the official launch of the 75D Model S is expected any day now.

However, we’ve now learned, via a post on Tesla Motors Club Forum, that existing/future 70D owners (since around the time of the refresh) will be able to upgrade to 75D via a firmware update.

Update (confirmed):  Tesla states that all newly refreshed Model S cars either have the 75 kWh or 90 kWh battery.  Meaning that if one purchases a “70D”, the battery is actually a 75 kWh pack and has been electronically limited to provide less range.

According to a post from gcgp, his Tesla delivery specialist was told by Tesla that new 70D owners will also have the option to upgrade to 75 kWh via an over-the-air software update.

gcgp states (via TMC):

“We’ve just found out that your Model S is going to have the option to upgrade via firmware to the 75 kWh battery pack. We don’t have official Australian pricing yet, but you’ll be able to do it before or after delivery. The US price will be $3,250, but our Sales team will have a call campaign to confirm with you once pricing is out.”

The question is, would you pay $3,250 for 19 more miles of range?

    No. Might rent it for a trip though

  2. SparkEV says:

    With expected range degradation, it’s probably better to keep 70 kWh and have extra margin in capacity than upgrade. I wonder if any S40 suffer range degradation since it had 60 kWh battery limited to 40 via firmware.

  3. Lunguuks says:

    That is a cool question, does the software limit maximum capacity without taking into account battery degradation over years? That would give 70 owners full 5 kW degradation for free, means no real degradation first 5-6 years:) In such case S40 owners will have their S40 for real till the car falls apart, not because battery is weaker. Good option for Tesla to unlock their inventory and CPO, although I suspect the upgrade is valid only to really latest production, where they probably used new cells like in 90. The “old” 70 then had same cells as 85.

  4. David Murray says:

    3,250 seems like a lot of money for 19 miles of range. That’s $650 per kwh.

    1. TomArt says:

      Considering that the option, new, costs $3k, they are gouging a bit, I think, by tacking on another $250 for a software trick.

  5. Four Electrics says:

    This leaves the door open for a firmware upgrade to 100 from 90. It’s possible Tesla wants to see real world degradation of the 90 batteries before deciding on the feasibility of potential upgrade. Perhaps this is just wishful thinking.

    1. vdiv says:

      Considering that Tesla likes to test their software in the field by their customers your hypothesis is more than wishful thinking. Relatively “tiny” 5 kWh differences spread over 6 to 7 thousand cells are unlikely, cell capacity improvement is a step function.

  6. vdiv says:

    Higher capacity can have other benefits such as greater propulsion and regen power, which is important in the cold. Not sure how Tesla would handle this with the same cells. Of course here we are talking about less than 10% improvement so it would be hardly noticeable, whereas $3,250 subtracted from my Starbucks budget would leave me without Grande Iced Lattes and Blueberry Honey Yogurt muffins for quite a while…

    No deal. I’ll counteroffer though with $325, you think Tesla will take it? 🙂

  7. Bacardi says:

    I believe this to be somewhat true but am not entirely sure which 70s can and which cannot be upgraded…I believe not every face-lifted S will be able to or they would have already announced it during the facelift announcement…Tesla just had an earnings call the other day and made no mention of this…

    I’d guess they’d want to exhaust the “old” 70kWh packs; we don’t know when that will be…Of course its possible it did already happen but it doesn’t seem very Tesla to announce a refresh, have an earnings call and to hide this feature…

    1. Jay Cole says:

      We are in the process of updating the story now, but we have heard back that all of the newly “refreshed” cars (and maybe some even before then) are equipped with a 75 kWh pack…there is no more 70 kWh cars, those packs are now discontinued/OoS completely.

      So all the 70D cars since at least the last ~2 weeks of April have this ability.

      1. Bacardi says:

        Thanks for the update!

      2. TomArt says:

        That was my assumption – I did not expect them to stretch an existing pack – they were 75s from the factory.

        Funny enough, a commenter two days ago predicted that this might happen!

  8. Speculawyer says:

    On disk paid DLC!

    This is going to really annoy many people.

  9. Stimpacker says:

    Looks like Tesla is trying hard to make up revenue from the reduction in sales of the higher end/optioned models.

    1. Bacardi says:

      Are you referring to the capped US deliveries in April? They allocate most of their deliveries to foreign markets at the beginning of the quarter…

      Yet Tesla does have a habit of increasing base models prices…

      1. TomArt says:

        It is annoying, but you are getting more for your money – it’s not like the increases are just increases with no material changes to the vehicle.

  10. Koenigsegg says:

    All the batteries are electronically limited.

    A guy in 2012 on TMC had a 40 and upgraded it to an 85.

    1. TomArt says:

      ??? That would dramatically increase the resale value of the S60s if that were the case. I thought that the S60s were lighter than the S85s?

    2. Otmar Ebenhoech says:

      I don’t see that this is at all possible. 60s, 70’s and presumably 75’s have 14 modules inside and a lower voltage. Larger packs have 16 modules.

      1. Yep.

        40 / 60 / 70 / 75 kWh batteries are all 84 cells in series (354 volts)

        85 / 90 / presumably 100 kWh batteries are all 96 cells in series (403 volts)

  11. Jacked Beanstalk says:

    Over $3K for a freakin’ firmware update to remove crippleware? Hell no. Bittorrent time.

  12. Windbourne says:

    I am curious where the extra 5 KWH comes from?
    Is it new cells, or is filling all of the cells up further?
    If the first, then it is probably good to buy it.
    If the later, I think that I would wait a bit and see what happens.
