Huh. You can calculate the torque at the wheels. It's definitely not enough to spin the tires. In general you need > 1g acceleration on an AWD car to spin the wheels. The measured acceleration for P3D with the Pilot Sport tires is EXACTLY the same as the P3D with the MXM4 tires. It's been measured many times by people in this forum.This is not correct. I think we can agree that the torque produced by either version of the car is enough to spin out the wheels of either tire, so it is the tire that fundamentally determines the amount of torque that can be applied at low speeds. This is a significant factor and relates to this roll out concept.
The car doesn't instantly start accelerating. 0.4s sounds about right for RWD though I admit I don't know which version you're talking about.It’s clear from the 0-60 time for the P that it is producing about 1g on average and clearly much more at lower speeds. This is much more significant when considering the 0-2.4s time of the S performance version. So yeah, 0.4s is absurd. Maybe 0.2s ...but that doesn’t even address my point that Tesla should mesure in a consistant way unless otherwise mentioned. To do differently would be unethical. So where is the evidence thay they use different metrics currently for P versions? Moreover, what as to my argument that from a simple power output point of view the times makes sense?
Constant 1g acceleration gives a 0-60 time of 2.7 seconds.
Tesla is a somewhat unethical company, sorry.
