    I'm thinking sticky tires, shed weight. Any other ideas? I'm wondering if it will perform better than stated like the RWD (some got 4.5 when it was claimed 5.1)

    Take off a half second before starting the stopwatch!

    We first have to ask ourselves if it's actually limited by physics or software.

    Someone made a thread months ago looking at what they calculated as the theoretical P mode specs. This was based on some assumptions but calculated the numbers via the weight of the car, the max power draw from each cell of the battery, and hypothesized it would be in the high 2's. The fact that it's listed as 3.5 makes me think of a couple things.
    1) Tesla may not want it to go 2.8 seconds yet as this would be too close the the model S value.
    2) What exactly is in the "performance" mode for the model 3. Will there be a future ludicrious mode to make it even faster or is this already included? At one time the model S had the following modes:
    - P90D without Ludicrous mode (0-60 in 3.1 secs)
    - P90D with Ludicrous mode (0-60 in 2.8 secs)
    3) The P100D awhile ago got an over the air update that dropped the 0 to 60 time by a tenth of a second. Do they plan to further reduce the model 3 P variant this way?

    Simple but disappointing answer is:

    Tesla doesn't want it any faster.

    The best salesperson on the planet couldn't convince a smart person to get a Model S over the 3 AS IS.

    What if you want a bigger car with a smoother quieter ride?
    Why would anyone buy a 7 series over a 3 series?
    It is true that there are probably many people who prefer a smaller vehicle who bought a Model S because it was the only long range electric vehicle available at the time.

    The 3 is bigger on the inside relative to the S, all other things being equal. It legitimately seats five people unlike my Volt. It covers the Sedan needs for almost everyone at a much lower price point.

    BMW doesn't make an M7 (in a practical sense). The S of course makes for a better cruiser or touring car than the 3 but most don't have those needs.

    Choices are good but the numbers dont really work in favor of the S.

    Find wrecked Model 3LR.

    Take motor and inverter from it.

    Swap the front AC motor and inverter for the PM parts. Fab brackets as necessary. Map tip in with a delay to avoid damage at 0-10 mph.

    Assuming 300lb weight gain, 10.4x @ 127. This is a P100DL killer. And why you got the MS75D front motor.

    Hunting exotics? N2 bottle with nozzles pointed at heat exchangers, motors, and batteries that fires off the solenoids when a threshold is reached. Remove everything that is not essential. Rear doors/hatch are CF skins. Front door have crash bars removed. All glass but windshield is Lexan. Build up front wheel drive. Stiffen rear suspension, single wheelie bar 1" from ground. 1 seat only. Seat is a CF bucket. Remove all speakers and amps.

    Note: You can't safely use CO2 or Nitrous. Any cabin intrusion can be problematic.

    Tesla can make the 3 run under 3 seconds any time they want to. But they don't want to. That wouldn't be profitable for them.

    But how fast can it do the Kessel Run?

    I think about 1.5 responses to this thread were helpful lol.

    I ordered mine, so when I receive it I probably ask service to take out extra seats at some point and make a video documenting my attempts

    The car quickly becomes power limited, even in a 0-60 mph sprint. Three seconds only requires ~ 0.9 G on average, well within the tyre traction capability.

    A future AWD Model 3 might be able to pull 5 C from the battery and have it fully utilized by the two motors.
    Then you are talking about up to 400 kW. Over 3 seconds that is ~ 333 Wh = 1.2 million joules
    If 20% motor losses, then 1.2*0.8 = 0.96 MJ to the wheels
    If 30% motor losses, then 1.2*0.7 = 0.84 MJ to the wheels

    Just the KE from 0 to 60 mph is
    0.5 * 1900 * 26.8 * 26.8 = ~ 0.7 MJ

    Conclusion:
    Possible for you ? No
    Possible for Tesla ? Probably

    I guess by the car’s motor and inverter. The AWD is surely just SW limited, since both have the same motors, maybe different inverters, but it really doesn’t make much sense to put in motors that can do 0-60 in 3s, or less and then limit the AWD to 4.5s.

    That would be massive waste in their most popular drivetrain configuration.

    I'm willing to bet that 3.1 is possible with enough weight reduction and some slick tires... Time will tell

    Unless you have a plan to remove ~ 500 lbs of weight, bet on something else.
    Your ability to skirt physics is ... limited
