For AWD owners wanting a P3D-

[john5520]

The brakes doesn't care if you got to speed X in 3 seconds or 20 seconds once you move from accelerating to braking.

It's human nature. With more power, you're going to want to drive faster and you'll get to speeds higher than you normally would much quicker. A better stopping distance can make the difference between stopping in time or slamming into the car in front of you, or worse.

Now driving like an idiot is the number one cause of speed related accidents, but that never stopped anyone, has it?


And the braking distance (60-0) between the 2 is about 15 ft or more. That's not a small difference.

With the same tires? I don't think so.

The 60-0 distance, with the same tires, is exactly the same

The brakes don't stop the car- the tires do. This is basic physics.

If you're unclear on this fact I highly suggest the following essay by a professional braking system designer who teaches SAE master classes on the topic and literally writes books about it:

GRM Pulp Friction

I doubt the tires are the same. I'm going by specs I've seen posted online.

Right. The specs online are showing you a shorter distance because the tires are different.

Put the same tires on both- stopping distance will be the same.

The brakes don't matter at all to stopping distance. The brakes don't stop the car- the tires do.

The brakes only need to be good enough to engage ABS (or lock the wheels on older pre-ABS cars)- which any stock brakes in the last decade or two easily can do... after that MOAR BRAKE makes no difference.

Read the link I posted- it explains all the things changing your brakes CAN do for you (and why other than "feel" none of them are useful outside a race track or the chase scene in a Jason Bourne film).... and it explains the one thing they CAN'T do- stop you any shorter than the stock brakes did the first time.

If you want to stop shorter you need stickier tires, not bigger brakes.

I read all the way through. Very interesting.

Its what you get stock. The P3D+ (upgrade package) comes with the PS4S which are fantastic vs. the stock 18s. The upgraded brakes really only help during track or hard driving in canyons (which I do frequently). the braking feel also is better on the upgraded brakes. If you are getting the performance, its a no brainer to get the upgrade package because they are literally the same price and you can always sell your 20s if you want smaller tires.

Does your crystal ball have any info on the chances of AWD non-P cars getting a full software unlock to P levels? Hopefully at least the 980 motor cars.

Bump

Seriously? You are bumping a 103 page thread? Is there anything new that can be said?

Anyone check this video out? Pretty interesting.

interesting.
If the Model Y has the same motors as the model 3, that would mean the model 3 performance motors can handle more Juice.
Wonder if the batteries can handle it in the 3 though ?

Are the inverters the same? Not enough info at this point to assume anything. The LR AWD with Boost would be an interesting race vs the Performance Y.

 

[Urbancowboy]

We really need a parts catalog or someone to at least take a photo of the rear motor on a performance MY. Would be great to know if parts are the same as M3.

Anyone know someone with a performance Y who would snap a pic and post here?

The Y has a bigger battery. Bigger batteries can supply more current to the motors. The question is, does a new Model 3 have the same, upgraded battery capacity as the Y?

Same size battery as the Model 3...the Youtuber mis-read the battery parameters...he apologized in the comments.

 

[anon52695]

But I like the extra power from the motors. That’s a good sign. Another update for the model 3 and maybe a little bit more for the AWD+.

Seems like we can soon go faster than the Performance in our AWD's.

Looking forward to seeing that "easy DIY" video on how to get more hp than the performance.

Long as you don't care about warranty on the impacted parts, sure

And no reason one couldn't do the same thing to a P, unless it's a REALLY crap hack like just boosting a raw output signal or something goofy where doing same to a P would likely break things.
