Rumored Tesla firmware update may allow Tesla P85D to achive 2.8 sec 0-60 - Polidicks

[quote]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.[/quote] [url]http://gas2.org/2015/01/29/tesla-p85d-0-60-mph-time-dropping-2-8-seconds-firmware-update/[/url]

It's cool that a free software update can make your car better. Via Elon's tweets about a week ago, he said it would improve by about 0.1 second. Seeing it drop to 2.8 would be staggering. 2.8 would put it just under the Lamborghini Aventador. I would like to see them do some work on top speed, as that is where it is lacking.

So as a non-automotive person, especially when it comes to Tesla vehicles, what exactly does the software do to improve that kind of performance in a 2.5 ton vehicle?

[QUOTE=Da Big Man;47088613]So as a non-automotive person, especially when it comes to Tesla vehicles, what exactly does the software do to improve that kind of performance in a 2.5 ton vehicle?[/QUOTE] torque optimization but i don't think a drop to 2.8 is happening, the musk tweet about the drop to 3.1 happened after these articles came out.

[QUOTE=Da Big Man;47088613]So as a non-automotive person, especially when it comes to Tesla vehicles, what exactly does the software do to improve that kind of performance in a 2.5 ton vehicle?[/QUOTE] The P85D has two motors, both electric and computer controlled obviously. By updating/playing around with the software that runs the motors they can make them work together more efficiently, optimizing the power of the vehicle. Or something like that. Could be magic for all I know.

[QUOTE=Da Big Man;47088613]So as a non-automotive person, especially when it comes to Tesla vehicles, what exactly does the software do to improve that kind of performance in a 2.5 ton vehicle?[/QUOTE] With that kind of torque, the main problem is probably going to be in not losing traction. Improvements in detecting when you lose traction, and maybe even adding the ability to predict traction and react to that, would improve performance. They can also change how they're using the engines, it's just magnetic fields being controlled by a computer, so there's potential there.

Modern ICE motors have all kinds of electronics regulating stuff, and by tweaking algorithms that run them, you can achieve different results.

[QUOTE=Da Big Man;47088613]So as a non-automotive person, especially when it comes to Tesla vehicles, what exactly does the software do to improve that kind of performance in a 2.5 ton vehicle?[/QUOTE] improvements in torque vectoring, which will be used by launch control/traction control and just electronic driver aids in general. This isn't too far from remapping the ECU of a normal ICE, difference is this is free.

They can't flood like an internal combustion engine, obviously, so the max RPM's is limited only by the amount of power available and the physical construction of the motor. So I'm guessing if they possess a limited top speed, it is because the physical design of the car isn't safe beyond that top speed. Also possible that they simply can't supply any more power from the battery, but I'm guessing it is an electronic limiter like on Crown Vic Police Interceptors (which can exceed 125 mph, but are electronically limited for safety).

Electronic vehicles have instant torque sure, but the torque dropoff as the motor RPMs get higher is still gimping the top end performance of these cars [editline]6th February 2015[/editline] see: [t]http://i.imgur.com/sgBp7vo.png[/t]

Would be interesting to see what an unlimited one would do. I think they should make a racing team where they try to squeeze performance out of it. Stock has no transmission, either. Couldn't adding one also increase top speed?

Plus theres other implications of running a gear box with an EV

I test drove a P85D on Saturday. Blood rushed to my ears, staggered my breath, I was holding on to the wheel for dear life. Basically: [media]http://www.youtube.com/watch?v=mk7VWcuVOf0[/media]

Plus theres other implications of running a gear box with an EV[/QUOTE] Depends on the shift points/gear ratios. All of Tesla's power comes from the bottom end torque it has. If you could put another gear that would plop you into the bottom end once the torque starts dropping off, you could take it faster. The only down side is that you will be eating a LOT of power......

Would be interesting but I don't think we'll see a Tesla with a transmission like that anytime soon. The electric motors would require a very large and heavy transmission for it to work properly, so it'd probably just be slower.

I'm afraid a racing series where ICE and EV mix just simply isn't possible with the technology right now

EV is capable of far too much instant torque, will shred a gearbox in no time. Top speed is limited by how much power the batteries could output, the energy required to make a car go from 100km/h to 200km/h is exponentially more power than it was to go from 0km/h to 100km/h

I don't really think the Tesla needs a transmission, it already goes pretty damn fast and a transmission would only complicate it further, add failure points and increase the price a bunch to only go faster. Although a smaller/cheaper version of it may require a transmission.

The new ones don't have two rear motors. They have a standard motor in the rear and a smaller motor in the front.

I wonder how much the traction control is working so the car doesn't swerve into a ditch. Im also interested on how much stress puts on the tires doing this. they have to be street tires. [video=youtube;HOmXCbVIU_c]http://www.youtube.com/watch?v=HOmXCbVIU_c[/video]

Wow, if you can download speed, maybe you can download more RAM.

Imagine somebody hacking into the firmware and making a custom one with numerous improvements.

Would I be a fool to buy one of these cars? I mean up until I've seen them come out I haven't heard anything short of amazing from them. Not to mention they are the typical price of an above average, off the lot car. I need a new vehicle bad, a new one I can take care of specifically. Would it be better to wait for prices? Maybe Elon will make way better models? Is this going to be hell on earth trying to get parts to repair if in any accidents? Insight from my lovely friends would be cool

Tesla is planning newer, cheaper vehicles but they won't be available for a few years yet. If it needs repairing Tesla will pick it up and bring it back to you fixed. Unless you tampered with it, or the car was totalled. [editline]8th February 2015[/editline] I'd do a lot of research first, and go to a showroom to sit down in one. It is still a lot of money to drop on a car.
