Took my Model S Plaid out for some testing today, using a dragy secured in a cup holder. Figured the results may be interesting to someone else.
MSP is a 2022, with factory 19s, completely stock everything, on an unprepped surface with no preheating of tires (other than highway driving to test location). Ambient temperature was 18 degrees C. Starting charge level was about 75%. Car was fully prepped in 'drag strip' mode, and the braking technique was to stomp on the brake pedal as hard as I could until the car was no longer moving. (I know, it's quite technically advanced, but I'm classically trained, don't worry).
Test setup was to perform 5 back to back 0-100-0 (Kilometers per hour) runs, measure brake disc temperature, then repeat. Results:
1: 0-100 - 2.50s, 100-0 2.87s
2: 0-100 - 2.59s, 100-0 3.18s
3: 0-100 - 2.52s, 100-0 2.78s
4: 0-100 - 2.51s, 100-0 2.77s
5: 0-100 - 2.48s, 100-0 3.09s
After run 5 I received the 'Brake Temperature Warning' light. Brake rotor temperature as measured with a fluke 64 max IR thermometer was 140 degrees C. Next series was performed after about 2 minutes.
6: 0-100 - 2.56s, 100-0 3.38s
7: 0-100 - 2.45s, 100-0 3.52s
8: 0-100 - 2.52s, 100-0 3.21s
9: 0-100 - 2.52s, 100-0 3.21s -> Yes, completely identical results. I read them back 8 times, this is what it was, twice in a row.
10: DNF
Was unable to perform the 10th test as at this point, the car completely lost it's mind and threw up seemingly every warning it had, including:
Traction Control / Stability Control / Launch / Cruise Control / Auto-Hold - Disabled, Acceleration Limited
There may have been more but that's about all I remember. Measurement of brake rotor temperature was again 140 degrees C, though note this was measured after several minutes of limping along with acceleration limited.
After about 10 minutes of driving the car mostly regained composure, though interestingly cruise control and auto-hold remained disabled even 30 minutes later, and didn't come back until I forced the car off and back on.
Also interested in what folks think of these results. To me this seems, disappointing? Not the 0-100, that it was so close to 2.5s back to back for 9 runs is almost unnervingly good. I'm talking about the 100-0, and in particular, the car just flipping out and disabling essentially everything.
