    Model 3 RWD LR VIN 27xxx

    Scanning through forums after I felt this recently that my model 3 has lost some of its power. There are a lot of reports of this. Apparently it stems back around the 18.3 update but can’t be sure exactly which update it was. But it seems Tesla slipped this in which has lowered the power of the motor. There have been many reports of how much better the car can do 0-60 with VBOX data. Getting 4.6s and 4.7s/4.8s respectively with 75-95% SOC. This now cannot be replicated as the motor has been muted a little. Now getting 0-60 around 5.3 seconds. Notice how Tesla has now changed the 0-60 times for the RWD on the order page to 5.4s (the old standard battery specs, if I’m correct) changed from the original posted 5.1 spec. What’s going on? If they were only muting the initial jerk and twist of the torque to protect the motor for warranty repair costs it wouldn’t change the 0-60 times by much at all. So I believe they have muted our vehicles to further differentiate the AWD and P models. AWD is spec’d At 4.7s and you can’t have two cars that have similar specs for sales. If this is all true I am disappointed. Because I didn’t ask for this. My car has definitely slowed down a bit. It doesn’t throw you back in the seats like when I first got it. I contacted Tesla, and they were angry that I would insinuate this and didn’t give me a straight answer but the VBOX data doesn’t lie. It’s almost a second slower now.

    Please inquire if you have experienced this. There is not a lot of in depth discussion about this topic but now that we have 3 model 3 trims out it seems like a business plan from Tesla to further push the faster more expensive vehicles.

    It’s definitely true the car was “nerfed”.

    That said long range RWD was always 5.1 and standard 5.6.

    They only slowed the car to meet their posted specs.

    I understand they may want to bring it back into specs. Just seems suspect. No one wants their cars slowed down. They were perfect from the factory. They recently changed the posted 0-60 spec on their order page? It’s now 5.4 changed from 5.1 as well.

    They've scrubbed the '5.1' number from the press kit as well. It only shows standard battery acceleration of 5.6 and "as fast as 3.5" in the opening paragraph.

    It’s just a let down. I’m not sure when you received your car, if you were shipped with the pre slow update but when you get in it one day and go to take an on ramp and it’s a slower car, it’s a disappointment.

    Interesting, since my last update (26.1) I'd actually thought they'd increased the starting torque as I've been getting wheel slip on initial acceleration that I didn't get prior to it. I've never actually tested the 0-60, but the initial accel seems to have been boosted recently to me.

    I don’t think they should be doing that. They sold the car with a 0-60 spec of 5.1. I’m no lawyer, but seems they may get themselves into some legal trouble with a move like that. I have the AWD on order. I definitely will not be happy if they change the 0-60 from 4.5 to something higher after I get the car. Now, I have no problem if they go lower!

    They must of changed it again.
    But still what I’m getting at is all models shipped are or were beating the posted specs. LR(5.1) best 4.6. AWD(4.5) best 4.3, Performance (3.5) best 3.18. Anyone would be mad if their car is slowed down and you can feel the difference

    Are we confusing km/hr with miles/hr in this conversation?

    Mountain Pass Perf car still seems to put out the same amount of HP it put out the first time they dyno'ed it. I think this is the first thread that claimed the 0-60 time changed. Most folks complained about the 0-20 acceleration feeling a bit muted.

    My bad, i didn’t think the 3.5 kms mattered .3 seconds but I guess that’s Tesla’s numbers then.

    The concenses is that most owners are feeling their cars have slowed a bit

    Let's say it together: "0-60 mph" does not equal "0-100 kph".

    They're close. But not identical.

    The Tesla website shows 3.5s 0-60MPH for the Model 3 performance version, and for "Long Range" it shows 4.5-5.1, but this covers both the RWD and the AWD. So it seems that it is still 5.1 for the RWD, and 4.5 for the AWD. The "Standard" version shows 5.1-5.6, but again this covers both the RWD and the AWD, so it seems the Standard RWD is 5.6s and the Standard AWD is 5.1s. It does not look like anything has changed to me!

    I’m not sure, but I believe someone was confusing km/hr with miles/hr. Apparently nothing has changed.

    Yes, but they have also worked around the system to disable traction control and that could be where the slowdown is implemented. Are you still working on a Go Fast Button for us, @Sasha Anis ?

    Maybe. It seems like we should be able to get the data via Draggy, but no one appears to be using it/have it.

    Our Model 3 is still making the same power as the day we picked it up. Yes, the traction/stability control defeat is coming! If it was something to do with TC it wouldn't show during our dyno pulls since we have it disabled.
