# Here’s How The Tesla Model S P100DL Manages 0 to 60 MPH In Just 2.28 Seconds – Engineering Explained Video

1 Y BY ELECTRICCARSTV 10

If you’re a math whiz, engineering scholar or master of physics, then this Engineering Explained video might be up your alley. If you don’t fall into one of those three categories, then perhaps it’s best to just revel in the fact that the Tesla Model S P100D with Ludicrous + mode can do 0 to 60 MPH in 2.28 seconds and leave it at that.

“How The Tesla Model S P100D Hit 60 MPH In 2.28 Seconds”

As hinted at above, this video is formula heavy and above the heads of most, but the gist is that there are all sorts of variables in play when the Model S P100D with Ludicrous + sets off the line. Variables such as power, grip, weight distribution, weight and so much more come into play. And when you’re pushing the limits, each of these variables can have a profound impact on the end result.

Oh and if you’ve ever wonder just how quickly a street car can mathematically accelerate from 0 to 60 MPH, the answer (as explained in the video) is approximately 2.05 seconds, so the Model S P100D with Ludicrous + is close to that theoretical limit.

What do you mean by a “street car” at 2.05 seconds?

He means using street tires with coeff of friction of about 1.1. EE did a previous video with race car tires that had 0-60 in 1.9 seconds.

I’ve personally did 0-60 in 0.5 seconds with my 1977 VW Scirocco. Someone using similar technique did it in 1.8 seconds with a Corolla. ðŸ™‚

0-60 what in 1/2 second? That’s front page news stuff.

Not really. Speedometer needle broke, so I broke the glass and used a paper clip. Then one can push the “needle” to any speed desired in half a second. It’s like what the guy in video did.

Another issue I do not understand clearly and that is Motor Trend changed its testing some time back (years?) to have a rolling start instead of standing start. Somehow this seems like cheating to me but can someone explain this statement from Motor Trend “We subtract a one-foot rollout from the launch to simulate dragstrip performance” and how much difference it actually makes.

It’s so easy to Google this:

The Two Greatest Sins Regarding Significant Digits

1, Writing more digits in an answer (intermediate or final) than justified by the number of digits in the data.

2. Rounding-off, say, to two digits in an intermediate answer, and then writing three digits in the final answer.

“But, but, but, my calculator gave me 12 digits.”

Yeah, these millenials… I’ve never committed such sin! ðŸ˜‰

Yeah, not to mention resolution, repeatability, margin of error, uncertainty, etc.

His results of 2.32, 2.28, etc. are probably no different from each other when considering the accuracy of the measurements involved.
