For those engineers out there, how many, or what percentage of G's does the P85 "pull" from 0-10, 0-30, 0-60?

It is Sunday, so no math for me.

Thanks!

Assuming 0-60 is 4sec, then the Model S pulls 0.7g

Don't know the 0-10 or 0-30 times off the top of my head so can't calculate the g's.

Just found the 0-30 time measured at 2.0s on this site, so still 0.7g

Deceleration is about 1.16g (30-0 in 27ft, 60-0 in 108ft)

So 0-60-0 is about 6.4 sec. And some uncomfortable passengers.

"So 0-60-0 is about 6.4 sec."

Which means I can go from 0 to 60 to 0 and back to 60 before my previous car goes from 0 to 60.

Did I get that right... I'm so confused?

@hsadler - Assuming your previous car took 6.5s or longer to get to 60, and assuming you have a P85, then yes, you could go from rest to 60 and brake to a stop before your old car would get to 60.

And in the process you'd go about 288 ft (96yds).

If you pace it out, it is a remarkably short distance.

Think football field. You'd be starting with your rear bumper touching one goal post, be doing 60 at the fifty yard line, and be stopped before you hit the opposing goal post (more or less).

Actually if you start with your bumper at the goal post (i.e., parked in the end zone), you'll hit 60 as the nose of the car crosses the opposite 45yd line, and you'd stop with your nose on the 9yd line (assuming you are driving on pavement and not on grass)

FWIW, As you come to a stop, Usain Bolt would be just crossing the 50yd line doing 27mph and would crash into the back of the car a couple of seconds later.

@nickjhowe

No no.... you misunderstood.
I said 0 to 60 to stop and back to 60. Much quicker than my SmartCar just going to 60.
And I don't have a P.

Anybody tried one of the accelerometer apps yet?

That would be a hilarious race to watch.

@txjak - I tried it but I ran out of road. Not only do you need to do zero to 60, you need to fund for a distance at 60 to calibrate it. Finding a road where I can do sixty, but also be stationary and not a danger to other traffic proved too difficult.

@hsadler - sorry for the miss. Yes, 0-60-0-60 would be about 10.5 seconds. and would beat MANY ICE cars.
