    Any direct control to battery pre-condition?

    I've found if you set the charge limit a few percentage points higher and start charging that will engage the battery heater. If you do this for 15-20 minutes before you go you can get about 50% regen.

    New Long Range Model S

    The carbon sleeve on the rotor reduces eddy currents which cause back EMF which is the reason Tesla's motors designs to date all lose a lot of power at high RPMs. Reference: https://www.arnoldmagnetics.com/wp-content/uploads/2017/10/ArnoldWP_-Automotive_FINAL-1.pdf However, by using a...

    New Long Range Model S

    The Plaid powertrain leverages carbon sleeved rotors on both rear motors which is the trick to maintaining power at high RPM. Tesla doesn't advertise the dual motor powertrain featuring that but... Tesla also likes to reduce manufacturing complexity, so it's possible the rear motor in the dual...

    Model S range and interior update imminent?

    Love the new S overall but disappointed that the Plaid models only come with Carbon fiber trim as an option. Also the your wheel options are now down to ugly but efficient and nice looking but inefficient (21"), I much prefer the old 19" style wheels. I've heard too many horror stories with...

    Model S range and interior update imminent?

    The reddit leaker bigteslaguy stated that the refresh would use 18650 cells. He was spot on about the Model 3 refresh that came out recently. So I think his info was at least correct / current at the time he shared. That said, I'm sure the battery will be a major step up in cooling and...

    More circumstantial evidence this is happening in Q1: Tesla tells employees Model S and X production will shut down for 18 days

    Model S range and interior update imminent?

    Carbon likely means replacing the copper windings with carbon. It’s lighter and can save up to 50% of the losses due to resistance. For example a 90% efficient motor becomes 95%. Besides improving efficiency and range, it also helps with the cooling problem in high performance applications...

    Model S range and interior update imminent?

    Maybe something like this... Prototype electrical motor uses carbon nanotube yarn in the motor windings (w/video) "If we keep the electrical machine design parameters unchanged and only replace copper with future carbon nanotube wires, it is possible to reduce the Joule losses in the windings...

    FSD rewrite will go out on Oct 20 to limited beta

    I agree they can't be compared with any other numbers, but can't they be compared with themselves? If the same methodology is used and the rates are trending down, that implies progress no?

    Navigate on Autopilot is Useless (2018.42.3)

    The lane selection issue still seems like low hanging fruit to me. The car can tell if it's in the right most lane based on vision, but if the map data is wrong, it will sit in the wrong lane approaching an exit it knows is on the right side and miss the exit. There's a stretch of road my my...

    Profound progress towards FSD

    It is in production. From the April 2019 Autonomy presentation:

    P85d vs Long Range Plus. Will I miss the performance?

    It would be great to see some more real world numbers from the S LR as your draggy is the first I’ve seen posted.

    Coronavirus

    Isn’t it obvious he’s worried about the pending disaster in Q2 financials. I really don’t think this is about his stock. It’s about his baby (Tesla)
