Didn't see your post. It isn't a fact per se, but good assumption given the abnormal launch and the propensity of British car reviewers to use 'brake torquing' when it isn't necessary... just like steve sutcliffe of Autocar did recently... Tesla Model S P85D vs Audi RS7 vs Alpina XD3 track...

Btw, back of the envelope math (wrt to rollout speed & time): 1ft=0.305m a=acceleration=1.1g *9.81 = 10.791 m/s^2 (you can play around with the initial g force, but 1.1 is the maximum) d=0.5*a*t^2 t= sqrt(2d/a) t= sqrt(2*0.305/10.791) = 0.238s -> time to reach 1ft (aka time to subtract for 1ft...

Actually in that video the problem is that they launched the P85D with both pedals pressed initially... They were idiots. There was a slight 'hesitation' as they say.

One thing I noticed: in the spec sheet, it lists the front motor gear ratio as 9.34:1. Can anyone confirm if this is correct? I've never seen any magazine report the front motor ratio so idk

Well, this is all hypothetical since in the real world the F1 doesn't have ANY electronic launch control or stability control, not to mention RWD only. The best data we have is the P85D vs. Aventador video w/ launch control. The aventador is faster on paper than the F1, and has AWD + launch...

I think it's probably the latter. Usually 1ft rollout is ~0.2-0.4s, 0.53s seems like too much. PBox is more reliable IMO.

If you take an average from say 45-65mph (power limited region with low drag) what would the whp be? I think the spikes in whp are just due to the accel spikes the graph had earlier, especially if you also see downward spikes. Unless your power meter went above 480kW although that seems...

Disagree. 1ft rollout is appropriate (and standard) for the quarter-mile, as that is the drag racing convention that has a technological reasoning: you need ~1ft to clear the beam at the start line. 0-60 times do not have this convention... There is absolutely no standard whatsoever. Most...

If the difference is indeed due to 1ft-rollout, then I have one question: What is the true 0-60 time for P85D? From your run (which is probably not under ideal conditions) it would seem to be in the mid 3s range rather than low 3s. Is that true? When Tesla advertises 3.1s, are they taking...

Either way, thanks for the data and graph. But it would be better if 1ft-rollout is turned off (I'm sure there's a setting somewhere), because it causes confusion with number comparisons.

Why does the graph show 1mph at 0.0s? Idk about the PerformanceBox, but, does it include 1ft-rollout?

Not the same. I would have given that theory some consideration, given that the 60kWh has been around for 2.5 years and sales are very low. P85D has been around for 5 months, and sells very well. There is no need to put out an upgrade this soon. I'm not suggesting Tesla isn't capable or...

Exactly. Well put. I don't know why @kris is thinking there will be a new model this soon, clearly with the 85D update, and the fact that the P85D is not putting down nearly as much as advertised, the update will likely happen soon. Also, it was promised on the website along with the 155mph...

Question to you and Stoneymonster: do the Dynopocket app results include 1-ft rollout? I think that it should be turned off if that is the case.

I'm not sure if you read/understood my comment so I'll clarify: Your original comment was about peak power vs. acceleration performance. You calculated that 350hp is necessary to accelerate an object from 0-60 in 3.1s. Again, that is right as average, but is a useless number because it is not...
