Dragy GPS Times

[gilscales]

I seen a video of someone who posted 4.7 on a LR model 3, mine did not seem that fast to me so I tested it out
went 0-60 9 times and best I could get was a 5.19 with no a/c on and a 86% soc (19" sport wheels), many people have commented on the off the line performance being nuetered after a certain software update, seems that may be so?

on another note I did one full stop just to see what I would get and it was 130 ft. so right as advertised

Is dragy with or without 1 ft rollout?

I am pretty sure the posted 4.7 sec was with 1 ft rollout. Could explain some of the difference.

The other poster also used Dragy

results around the 1:50 mark

Dragy does not calculate 1ft rollout.

Dragy does not calculate 1ft rollout.

Clarification

It does actually, for distance measures (1/8 mile, 1/4 mile, etc)

It does not for speed measures like 0-60

That's pretty weird that they'll do it for 1/4 mile but not 0-60.

Apparently it’s to reflect how nhra timing works for distance times at tracks

The 4.7 draggy was in April before the unconfirmed nerf that many people reported.

 

[chinnam3]

I did feel the difference right after firmware update, then started searching forums to see if my car has issue, but it seems many folks felt sameway about Nerfing. I am not saying Tesla did it intentionally. May be this was results of some traction control logic tuning, but I think something changed on how it pulls esp from 0-30.

My results, tried to post them earlier but for some reason they did not go through.

So,
0-10 0.75s
10-20 0.83s
20-30 0.80s
30-40 0.82s
40-50 0.88s
50-60 0.91s

Why does everyone say it's soft off the line? Looks like a flat torque curve to me slightly tapering off when it hits the power peak.

It's a "butt dyno" thing. I don't have any hard data but it doesn't really put me back in the seat until 10-15mph(ish).

Perception isn't linear here?

That's your brain messing with you. I get the same feeling in my Model S 85, it seems to pick up around 25mph. But videos of my speedometer during a 0-60 sprint don't support that- just pure, linear acceleration.

It's the combination of things moving faster in your visual field (combined with the existing acceleration) that convince you it's going faster. Try getting somebody to do a 0-60 run with you in the passenger seat, but close your eyes and see if you can tell if the car "picks up."

One theory I have is that some people are used to ICE acceleration which drops off dramatically when the transmission shifts from 1st to 2nd gear. There is no drop off in a Tesla so it's especially powerful relative to ICE in the 30-45mph range (before it hits the power limit).

Reasonable. Hard to argue with the data above.

More Data 1/8 and 1/4 mile

 

[Jedi2155]

I see a clear ramp up in acceleration up to maybe 10 MPH based on your most recent charts. Interested in seeing a similar chart from a P3D or 3D.

You are reading the this wrong, last 2 posts are of 1/8 mile and 1/4 mile runs and are not 0-60 runs, based on my comparison of 24.8 to 28.1 software there is no difference in acceleration.

Ah, was not aware Dragy was doing a post-processing on the data. I heard that all the acceleration "rumors" are simply that and there has been no actual change in firmware.
