Are they from 0 or with this roll out business which I frankly don't really understand or like? Hope from 0 as it's the car I have on order

That's awesome!
If this is from standstill the chart on the first page needs to be updated - these numbers were put into the 1-foot rollout/asterisk column.

Would be interested to see your times with a 1-foot rollout
Very interesting result... So close to a P85D...
But how do you manage to get this level of precision with PowerTools, since all data coming from this app is measured on a 1/4 of a second basis?
So basically, you can only get some times ending with .00, .25, .50 or .75 (more or less, depending on the timestamp when you floored it...).
At least, this is the way it works for me. Did you do some kind of interpolation?
Yes, if the runs don't produce the exact speed, then I have to interpolate the time.
example, 33.5s = 58mph, 33.75s = 62mph, then I assume each mph takes 62.5ms, so I will use the result 33.625 as the time to 60mph (33.5 + 0.0625 + 0.0625)
The Tesla accelerates so linearly that interpolating the in-between times should be close enough.
I don't interpolate the initial launch time though, so it assumes the worst case scenario.

Thanks Pete.
Looking forward to you getting that beast of yours on a strip so we can see if the sub 11s quarter time claim can be validated.

BTW, here is a breakdown of actual times from 0-60 (not with 1ft rollout).
I feel like there is room for improvement. If you notice 0-30 is less than half the time, but 30-60 is where the power is dumped. Also, in a previous run I reached 60 in 144ft, so I don't know why it took 10 extra feet this time even though this is the fastest 0-60 (no 1ft) I've gotten yet. Maybe measurements were flawed the previous time.

| Speed (mph) | Time (seconds) | Distance (ft) |
| 0 | 0 | 0 |
| 10 | 0.34 | 3.05 |
| 20 | 0.80 | 13.02 |
| 30 | 1.25 | 29.65 |
| 40 | 1.73 | 54.17 |
| 50 | 2.32 | 93.68 |
| 60 | 3.06 | 153.48 |
Very interesting.
Request: Can this thread be made a sticky? Either here or in Driving Dynamics. The Thread Summary at the start is an excellent comparison (and may need to be revised in the light of software updates/ magazine reviews - hopefully)

What was the setup? Battery%, Wheel size, tire model & pressure and pano roof or not(weight).
This is my run : Stock 2015 Tesla Model S 85D 1/4 mile Drag Racing timeslip specs 0-60 - DragTimes.com
[email protected].
90% SOC, Base 19in with oem michelin@50psi and I have the pano roof.
This track is a bit slippery, it's an old airport so it's concrete instead of asphalt.
19" wheels, 84% SoC on the best run, not sure about tire pressure (I check them fairly regularly and set them at 45), factory Michelin Primacy tires, pano roof, and a 250 pound driver. ;-)
Another 85D owner at the track last night was running pretty consistently 0.15s faster than I was. He was probably 100 pounds lighter than I am. I did race an 85 and from video of that race it would appear this track was somewhat sticky in spots. (All you could hear was the tires peeling off the asphalt in a rhythmic fashion. :wink
I did try runs with the suspension lowered and the mirrors folded in (separately and together), but those didn't seem to make any measurable difference. For me, the only performance variable of any magnitude was SoC.
My 1/4 mile times and speeds, plus SoC and peak power data from PowerTools:
#1 - 13.171 @ 108.38 (my very first race, ever! Forgot to start PowerTools)
#2 - 12.619 @ 108.56 (84%, 363kW)
#3 - 12.667 @ 108.26 (82%, 361kW)
#4 - 12.664 @ 107.95 (79%, 357kW)
#5 - 12.694 @ 107.56 (77%, 356kW)
#6 - 12.738 @ 106.93 (74%, 352kW)
#7 - 12.738 @ 106.91 (72%, 351kW)
#8 - 12.809 @ 106.79 (70%, 349kW)
No two runs were less than 15 minutes apart, and many were 30 minutes apart.
Did a couple of 30-50 and 50-70 runs on a 90D, this time steady at 30, then stomping on gas and looking at power tools log for the time delta from 30 to 50. Same for the 50-70 run... drive at 50 then stomp on the gas pedal.
30-50 was ~1.33 sec (74%soc) -- (according to logs, it was 1.25 sec from 30-49mph and 1.5 sec from 30-52mph)
50-70 was ~1.91 sec (74%soc) -- (according to logs, it was 1.75 sec from 50-68mph and 2.0 sec from 50-71mph)
30-50 was ~1.33 sec (74%soc) -- (according to logs, it was 1.25 sec from 30-49mph and 1.5 sec from 30-52mph)
50-70 was ~1.91 sec (74%soc) -- (according to logs, it was 1.75 sec from 50-68mph and 2.0 sec from 50-71mph)
