Tesla Model S Plaid full performance tests 1/4 Mile

i wanted to see how well my ET_Analyst software models an Electric Car ???
.... it seems it did pretty close !

differences between SAE J1349 -vs- SAE J607 HPCF is about 1.04 to 1.06 range

the YouTube and Internet Article said 1020 HP SAE J1349
which could be around 1060.8 HP -to- 1081.2 HP ??

the very 1st Run ET_Analyst Data looks like what i'd expect
to see with an Electric Car with CVT transmission ! 8)

However , the rest of the Runs , such as , 4th and 6th Runs
look like the Telsa had battery problems ????? :?:
....... anyone care to comment on this ???????

DragTimes recently was able to spen some time with the all-new,
red Tesla Model S Plaid at the Orlando Speedway drag strip
and record full performance tests.

When put in Drag Strip Mode, the car quickly reported that it is ready for the job
so the team was able to conduct multiple runs.

The times were very good,
including 1/4 mile in 9.248 seconds at 150.65 mph in the second run.
That's just 0.001 s behind Jay Leno's record.

We listed the results from the video below,
but please take note that some include rollout (like the best 0-60 mph time in 2.01 seconds).
The Dragy appears to report a true 0-60 mph time around 2.21 seconds.

1st try - results (dragy):
0-60 mph (96.5 km/h) - 2.21 seconds
1/8 mile - 6.03 seconds at 120.82 mph
60-130 mph - 4.71 seconds
100-150 mph (240 km/h) - 4.74 seconds
1/4 mile - 9.28 seconds at 151.48 mph
Track measure: 1/4 mile - 9.264 seconds at 151.83 mph

2nd try - results (dragy):
0-60 mph (96.5 km/h) - 2.21 seconds
1/8 mile - 6.01 seconds at 121.23 mph
60-130 mph - 4.64 seconds
100-150 mph (240 km/h) - 4.67 seconds
1/4 mile - 9.25 seconds at 151.99 mph
Track measure: 1/4 mile - 9.248 seconds at 150.65 mph

Seems like it would be interesting to see what effect air density has on MPH and if the lower density shows up as higher developed horsepower at the end of a high altitude track.

Certainly it won't much difference to ET, but it could easily be a 10 "horsepower" difference.

EVs are fastest/quickest with a fully charged battery pack. Performance slows as it is drained.

Also, Tesla has balanced ultimate cost,weight and performance, using wiring harness which will handle 1/4-mile at a time, but not full speed closed course racing. On longer road courses, the Tesla will reduce power in less than one full lap to avoid overheating the wiring harness.

Which is entirely understandable. Most other vehicles in the segment would do the same on a road course, and the plaid is more about who's eco-wang can smack down the loudest gas guzzlers on the street*.

Also that wheel? On a road course? Ewww...**

thanks for that Info !

the 1st Run had full Battery charge ... and my Simulation shows it
from that point on... it appears there were Battery problems or Telsa software protecting wiring harness or combo of both ??
Also you can see they were making almost back-to-back Runs according to ET Slip's time of Day

just looking only at the Time Slip Data
its easy to see which Run is quicker or slower ,
however , its hard to tell from the ET Slip just how much HP varied so much between Runs,
and it was easy for my Software to show the large differences in HP output at different distances
that normally you would not think was happening from the ET Slips . 8)

I can't speak to lithium batteries.
I do know from hard learned experience that lead acid batteries that are tasked hard repeatedly never recover the to same capacity as it had during the previous task or the one before it. It's a slow road to battery failure.
If lithium is the same way it's another little detail the ev fans don't want to discuss.

Lithium batteries have a lot of variability in chemistry options.
The chemistry is tuned to fit the aims of the application.
Whether it is durability, fast charging, cost etc, each priority calls for a different chemistry (there is a lot of R&D work being done on battery chemistry, huge demand for experts in the field).
From what I see, there is still a lot of upside potential in battery development.

Agree with all the above.

The LG Chem/Chevrolet Bolt LiOn batteries were built with the best technology available in 2016 and they've still had twelve fires in 180,000 batteries and they're a slow charging design.

My prediction is as battery development attempts to leapfrog into ultra-rapid charging, thinking that's what the market demands, this has the potential to be not just fires but explosions.

That ultra rapid charging is getting faster and faster.
Vehicles like EVTOLs where very gram counts prefer not to carry the hardware needed for fast swaps.

Doesn't Speedtalk have an electric car sub section?

I know as much as I can learn and try to keep an open mind to anything!

If I didn't overthink stuff I wouldn't be on speedtalk!
