Tesla P85D 0 to 60 MPH Time Dropping To 2.8 Seconds With Firmware Update?


Elon Musk said that he wanted the Tesla Model S P85D, to be as fast as the McLaren F1 hypercar, and with a 0 to 60 MPH time of just 3.2 seconds, Musk seems to have acheived his goals. But could the P85D go even faster, and with just a software update? A post on the Tesla Motors Club forums hints that this could be the case, and soon.

User anxman posted the following on the TMC forums, the source of these rumors;

Hello folks,

I’m happy to bring you a TMC exclusive rumor. According to my sources deep inside Tesla, a firmware update for the P85D will increase its 0-60 performance from 3.2s to 2.8s. I have not personally operated this P85D, but my sources have allegedly seen it in action and historically these sources have been accurate for Tesla rumors. Please take it with a grain of salt because I have not seen or operated this vehicle myself.

My fingers are crossed — though, I’d rather see Active Blind Spot Detection and Autopilot features before this bump to the “Insane” mode.

So is that enough to go on? Normally not, but other posters quickly came to back up the statements, supposedly coming from Tesla store employees. But why would Tesla wait to drop the P85D into an even faster speed bracket, and how do they do it? Well another poster may have the answer to that as well. From the same thread;

Yes the 0-60 time can be decreased by optimizing the torque on the two axis. Actually I read on TMC that such a decrease was possible from the very beginning of the P85D life but that Tesla designers decided to get 3.2 secs because they didn’t manage to have a continuos acceleration by lowering such a number to 2.8 secs. In fact they had issue to harmonize the acceleration of the two motors.

Maybe that now in Tesla they managed to work out the issues between the two motors and get 2.8 secs.

But IMO the driver should enter a password to get 2.8 secs just to let him think twice before of using such an acceleration.

Good advice. We’ve seen how the Tesla P85D can turn anybody into a laughing, cussing fool thanks to its instantaneous acceleration. More importantly, if true, this firmware update really demonstrates another advantage Tesla holds over its competitors; namely, the ability to improve and repair their vehicles without ever bringing them into a service center. Previous firmware updates have added the ability to open your Tesla with a smartphone and help avoid potholes along regular driving routes. And now, apparently, a firmware update will make an already fast car even faster.

Remind me again why people don’t like Tesla?
