    We picked up our P85+ today at Fremont. While sitting at a charger this evening in Monterey, my son crawled under the car to see if we had a "D" pack and were suprized to see the P/N ended with an "E". Anyone know what has changed to roll the part number revision?

    Just a guess, but perhaps this is due to P85D requirements?

    Must be. The D draws a significant amount of current. Probably updated the current collectors and main fuse.

    Hopefully they have also updated those pesky contactors that have clunked so many folks to a stop (not us, still with an A pack, fingers crossed).

    Interesting...

    Don't suppose you can take a snap of the door post's tyre and weight plate too please?

    Had a loaner this week with a D pack but VIN 45439 (sept build) and the contactors had a very different noise, so my guess is that there are using something new already for some time now.

    Thanks for the report @rceldib and @Majerus

    Yep. Noticed the same thing on my S60 loaner last week. They're quieter.

    Does anyone know what the latest revision of 60 pack there is out there?

    For reference, my car (VIN 55228) started production on the morning of the start of Q4 and has a D pack. My money is also on changes for dual motors.

    - - - Updated - - -

    Interesting...35k miles on an A pack, 2,500 miles on a D pack and I don't notice a significant difference in the contactor sound. I'll have to pay more attention, but if the sound is different it seems subtle to me.

    My Sept 2014 car had a D pack. VINs don't mean much here since they have no relation to build order.

    +1

    I would like to see that. Are the cars lighter?

    We just got back from our Tesla factory trip picking up our new Model S with the E Pack. We charged at Gilroy, Atascadero, and Tejon Superchargers. Gilroy was pretty busy with I think six cars charging. We were floored to see 198 mph charge at 153A and 385V as our Rav4 EV charges so slowly.
    We then charged at Monterey on. Tesla standard charger with 26 mph at 47A and 232V.
    Took a picture of our door weight tag:
    Tag date. 11/14
    GVWR. 5710 lb
    GAWR. 2723 lb
    GAWR. 3131 lb
    Then charged at Atascadero. I took a picture of the tag on the Supercharger white box that I thinks has a lerge battery set in it. The tag stated:
    Input voltage. 200-480 VAC
    Input current. 280A @ 200-240 VAC
    3 Phases
    Output voltage 50-410 VDC
    Output current 210A MAX Continuous
    Weight 1320 lbs

    Okay, at Atascadero Supercharger:
    Max charge rate was 381 mph at 314A and 368V. Wow that was fast. We were the only car charging and got on the charger closest to the power packs and it was an "A" labeled charger.
    Darn, the other pictures of charge rate are on my son's phone. I will post shortly.


    Still have to find the our data from Tejon Supercharger but as I recall it was even faster.

    btw this car is awesome. I have been an auto engineer in Detroit in the past and an aerospace engineer in SoCal for many years, have owned 60 interesting cars over the years and the Model S stands above them all.

    The weight listings on the door sticker aren't going to help you much. The GVWR is the Gross Vehicle Weight Rating and includes the passengers and cargo. It's basically the maxium (fully loaded) weight of the car. Tesla reducing the weight of components isn't likely to reduce this unless they weaken suspension and frame parts. The GAWR is the Gross Axel Weight Rating, which is the maximum weight each axle can carry. Again this includes cargo and passengers and isn't likely to change with a battery change. I do note that this vehicle has different GAWR values than the September 2014 S85 (2813lb FRT/3307lb RR) I traded had but I had 19" wheels and this is clearly a P85+ (note the staggered tire sizes), so I believe that accounts for the differences (we know the P85+ has a different suspension setup).

    In order to draw any conclusions you need the curb weight. Which Tesla doesn't publish anywhere on the vehicle. However, Washington requires it as part of the title application and Tesla provided 4,594 lb for the S85 I traded. I'd imagine you'd need to find a recent identical configuration (even things like the Pano roof probably change the curb weight) with a D battery to compare to.

    None of those charging rates are unusual for a Model S at a supercharger. One thing to know is that the charge rate tapers, so it starts off very fast and slows down as the battery fills. So your charge rate at Monterey may have been impacted by the State of Charge (SOC around here) when you were charging. I believe US speced SuperCharges top out at 120kW (EU I think is 135kW but someone will probably correct me if I get these numbers wrong) and your Atascadero rate was roughly 115kW. So none of this is out of line with what we would expect. There's no evidence that the E pack is charging faster than the D pack so far.
