MASTER THREAD: "Acceleration Boost" option, discussion as to which models and how much quicker

[LACALawyer]

Some before and after acceleration testing of a AWD+ vs a Stealth Performance has surfaced. Skip to 1:40 if you want to see the boosted difference.

The Performance still pulls away but it's much less pronounced. Here's to hoping for another boost package for LR AWD to go full P.

Also saw someone tweeted to Elon tonight asking for "mid range love too" while citing a link to a race video of a boosted AWD and Elon replied "Ok" so it looks like maybe there are more of these boosts coming for the RWD models. I bet that the "BASE_PLUS" found in the source code by @greentheonly might be this very boost.

In other news, I got my booty spanked earlier by what looked to be a 2019 BMW M5 out on the roads. I didn't realize those cars are running 600+ hp now stock...good lord. I will say that running at 45% SoC, the boost is much less noticeable. Felt only slightly stronger than a 100% SoC unboosted AWD, so there's that. It would be interesting to see a race between an unboosted AWD at 95% SoC and a boosted one at 45% SoC.

No matter how much you wish for it, they WILL NEVER MAKE A LONG RANGE THE SAME AS A P.

Why do so many people carry that silly fantasy?

NEVER GONNA HAPPEN!

I believe the timing of this enhanced performance upgrade is perfect.

Many Tesla owners will want to buy themselves a nice Christmas Present

It seems to be an inherent interest, in many automobile owners, to make performance enhancements in their cars.

While not for everyone, this upgrade will be desired by many.

For gassers, obtaining a 1/2 second power gain usually entails many comprimises. Poor mileage, lumpy idle, lower down low pull, louder noise, loss of warranty, lower resale, and the loss of the "keeping it stock" label.

With Tesla, other than the expenses, there seems to be no downside.

Well you never know. As a lawyer, you should know “Never going to happen” often can.

Also think it is perfectly executed, as the upgraded Stealth is still slower than the more expensive P3. Still gives the P buyer the performance edge they paid for.

The boost wasn’t meant to compete with its superstar brother that competes with the M3. It was meant to runaway from pesky M340s and C43s from the Germans

Anyone else with a Stealth now seeing an Upgrade option in the Tesla app? Shows nothing available (of course) but that i bought FSD after original purchase as “Purchased”. My X does not show this on the App.

Edit: ok I’m an idiot. I guess it’s because I recently updated the app for it to show. Just weird it doesn’t show for X.

Interesting video. It's less pronounced but it's still a spanking at any close-to-legal speeds, as you'd expect. In a few of those runs the LR AWD even got the jump, and the Performance 3 still strolls on by.

Agreed. This illustrates what another 50 or so hp and tq looks like and what it means in real world with side by side pulls. It also demonstrates how many actual car lengths that much power difference will make in real world all other things being equal. The real question is whether an AWD is full capable of P power or not. Are there really any bits of hardware preventing a full unlock or not?

Yes and No. It seems to depend upon delivery date. Different spec Inverter in the rear motor unit between the Perfomance and standard LRAWD built on/about/after April/May 2019. 980s are P/N for the rear motor assembly with inverter, vs 990 P/N on the rear motor assembly for the standard LRAWDs built after April/May 2019 or so. LRAWDs built prior to April/May 2019 have the same 980 rear motor assembly as the Performance models. Therein lies the never ending debate in this forum..

And thanks for starting it up again...

I would buy it for $500. But $2,000 seems like a lot for a 0.5 second improvement to an already very quick car. It isn't atypical for car companies to charge $2,000 or more for performance packages, but they usually bundle in a number of items, such as better brakes, upgraded tires, whatever. But $2,000 for only the 0.5 second improvement seems steep.

As has been discussed, at the speeds these cars accelerate now, shaving another half a second off is massive. This is not a steep price at all. If I owned a LR AWD it would be a LR AWD+ in a hot (half) second.

Im pretty sure performance guys will get 3.0 speeds for free, and the option of ludicrous mid 2sec for a upcharge, and we LR AWD+ will be upgraded to performance speeds 3.2-3.3secs......This motors, battery are capable of 900hp if tesla really decides to unleash them.

And you know this, how?

According to this Electrek article, the Acceleration Boost equates to +50hp. That's a massive horsepower increase for $2000.

Another side effect - after the upgrade the car sounds different.

I notice the difference sub 40 MPH, there is also a slight difference in the vibration of the steering wheel.

There is definitely more sound coming from the front of the car now.

Now I have put a lot of noise insulation in my car (see the big thread on it), but the most noise insulation was put in the rear of the car. Now that they are working the front motor more, perhaps it is simply that my car has less noise insulation in the front, that makes the front motor sound louder now.

Perhaps it is induction vs permanent magnet, but the front motor feels/sounds harsher than the rear one.

Note that this is on smooth asphalt at low speeds extreme quite conditions.

Haven't noticed this, only the blood rushing from my face to the backside of my head!

Indeed, and really the HP isn’t just the only thing. A half second at these speeds already, with “only” 50hp added, is boggling my mind. The way these motors are “tuned” is really something.
