# Tesla Model S P100DL 0 to 60 MPH In 2.28 Or 2.53 Seconds? Or Are Both Numbers Right? Video

For all the math lovers out there, Engineering Explained went back to the drawing board, releasing a new video entitled, “* Tesla Did Not Hit 60 MPH In 2.28 Seconds?”*.

The new video was added to show that they had left out a key piece of information related to rollout, when publishing the original video about the Motor Trend’s 2.28 second, zero to 60 time for the Tesla Model S P100DL.

According to Motor Trend:

“We subtract a one-foot rollout from the launch to simulate dragstrip performance (dragstrip runs started the whole quarter-mile acceleration craze and remain the only practical way for most owners to test their own cars, so we want our numbers to match those acquired in this way).”

Car and Driver put out a post entitled *“The Importance of ‘Rollout’:The first few inches of a drag strip,”* which explains “rollout”:

“Should the owner of one of these performance meters want to compare its performance against the authoritative equipment used at drag strips, he or she will need to deal with “rollout,” which is the distance a vehicle can move before triggering the timing lights.”

You can read both the Motor Trend and Car and Driver posts related drag racing and rollout, in their entirety, at the links included at the bottom of this post.

Video Description via Engineering Explained on YouTube:How Tesla Hit 60 MPH In 2.53 Seconds, And How Rollout Works

The Tesla Model S P100D set a new record with a 0-60 time of 2.28 seconds, as tested by Motor Trend. Originally, this seemed impossible based on my theoretical limit of 0-60 mph in 2.32 seconds from the braking distance of a P85. Thankfully, Jason Cammisa and Frank Markus of Motor Trend contacted me and we worked through their numbers. The critical piece of information which I left out in my first video is that the 0-60 time of 2.28 seconds excludes the time for 1 ft of rollout. In that first 0.26 seconds, the Tesla has already reached 5.9 mph before the clock has started ticking. This video explains rollout, and why it is used by all the major auto magazines.

this means that likely the Faraday Future was way off too?

Faraday future = faraway future

To U.S. car enthusiasts, this is so over-played. One foot roll-outs have been the standard reporting of 0-60 times, at least as far back as the 80’s.

So, why did Engineered Explained wait until Tesla came around, to post their rant? Bias?

Seems truthful. The 2.28s should read as the time from 5.9 mph to 60 mph.

Just watch the first 30 seconds and you will know.

As an engineer, seeing numbers in pounds, feet or fahrenheit hurts my brain. Using those is worse even than voting for Trump!

Because poor little engineer cannot perform unit conversions? Aww…

When there are much better alternative measurements, I can understand his point. No reason to be snarky.

The 1 foot rollout is also traditionally supposed to level the playing field for not-so-perfect launches. That way a poor driver wouldn’t have as much impact on a car’s numbers.

And it used to really not matter at all what happened in the first 1 foot in a 1320 foot quarter mile race. It just didn’t change times that much for 1/4 mile races back when they started using rollout on drag strips.

But the crazy thing is that the Tesla is so damn fast off the line, that all the sudden, it actually matters.
