21 Model YP slower than M3 w/ AB?

[Moopwomp]

So I recently bought a used 21 MYP, and while it’s quick, I was a bit disappointed by the acceleration. It just didn’t feel as quick as I expected.

I had to bring it in to Tesla because the door was groaning loudly when opened, and they gave me a 2018 M3 with AB as a loaner. This thing is noticeably faster than my MYP. My wife even noticed it right away - the M3 is a gut pushing acceleration, while the MYP is fast, but always comfortable.

Anyone else have experience comparing the two? Is there something wrong with my MYP? I have gotten a “front motor temporarily disabled” error a few times, and the car is obviously much slower when that happens. Is it possible it has slightly reduced power all the time, it’s just not telling me?

Any message such as "front motor temporarily disabled" is definitely a problem. I would think you would want to have Tesla address that error versus a creaking door.

You did not provide the battery state of charge (SOC) for the PMY. When the SOC is less than ~70% then maximum power output will be reduced. If you are used to getting maximum acceleration on demand you probably would notice the difference.

I think that it’s normal. I had the same experience/gut feeling. And I do believe that the lr3 with AB is faster out of the hole the car is lighter. It about getting mass moving. IMO.

Tesla is also investigating the motor issue, no worries there. Though I’m not too hopeful, since I’ve read other posts where they just say it’s a firmware problem that will be fixed in an eventual update.

I guess I’m mainly surprised because the posted 0-60 times for M3+AB and MYP are 3.7s and 3.5s, respectively. So I wouldn’t expect the M3 to feel noticeably faster… but the seat of the pants difference is night and day. To the point where the wife wouldn’t let me floor it in the M3 because it was too fast, but no such complaint with the MYP.

Plenty of PMY owners report 0 - 60 times of 3.6 seconds. I'm not sure you can expect 3.5 sec runs with a passenger too. You can shave 1/10th second or a little more off the PMY time with smaller, lighter wheels.

I have lighter 19” wheels, so already there. Even so, that’s still about the same as the M3, but the M3 is clearly faster.

I think I need to get a draggy and just measure it.

A buddy with a couple year old M3 AB drove my 2023 MYP and it felt a little faster to him. I haven’t driven the M3 so I cannot confirm or deny. They seem like they would be close enough that it would be hard to tell the difference. Maybe you are mostly feeling the body roll/suspension difference.

I had a M3 LR Dual Motor as a loaner, and something about it just felt snappier. No acceleration boost, but I think it's the smaller nature of the car fooling you into thinking it's faster. My MYP is definitely faster in a straight line... but it feels heavy by comparison.

All things being equal, the two cars (MYP vs. M3LR+AB) are pretty close to the same 0-60. Car & Driver timed the MYP at 3.6 seconds. They clocked the M3LR at 4.1 seconds. So, if you deduct another 0.5 seconds, that equals the MYP.

It is super hard to judge based on feel, other than a clock. Both cars are very close to linear until 60, so there should not be any sensation of acceleration "out of the hole." Both are going to pull a flat ~ 0.76 G the whole way.

With just a butt dyno, I think it’s in your head. Most likely the poorly built model 3 under a tent with panel gaps and less sound dampening appears to be faster. It’s like an old riced out Civic or RX7 back in the days appeared fast when you chirp the wheels, rev and shift with the interior rattles and lawn mower engines.

Install a phone app that will measure your 0 to 60. It won't be 100% accurate, but it should be close enough.

I think that the MYP figures are quoted with a rollout. The M3+AB is likely without rollout. That'd make the actual M3+AB figure ~.1 second quicker.

I wouldn't have expected that to be noticeable, but I would expect them to be very similar.

They are very similar in straightline acceleration. Cornering is whole other world, the M3 +AB feels much better cornering, but that's just the fact that it's not as tall and the seating position is much lower.

Do all tesla M3 fleet loaners have AB? i had a 2017 loaner with 92k miles. i had a MYLR w/o AB.

No, AB is an option for $2k. on the M3LRAWD & MYLRAWD

Good news, Tesla is replacing my front drive unit under warranty. We’ll see how she feels when I get her back, but it looks like the butt dyno was reliable after all!

Don’t know. I’ve only had a single loaner and it has both AB and FSD enabled (though on an old version). Might be a trade in they repurposed, so it could depend on what the car came in with.

I don’t think it will be any quicker. I’ve bought a MYP to have alongside our M3P and even though 0-60 speeds are just 0.03 seconds slower in the MYP the difference in feel is out of this world, the M3P turns your guts and makes you feel dizzy. The MYP never. Having said that it hits the advertised 0-60 so it’s not slow. I guess it’s just size and mass of the car doesn’t feel quick

The fun way I like to think about it is how many Gs is the car pulling. Acceleration in both cars is relatively linear until you get past 60 MPH, so in a 0-60 run, the MYP is pulling 0.79G and the M3P is pulling 0.89G. If you are a 200 lb. driver, that would feel like another 20 lbs. of force against the seat. That is a lot of force.

Its nearly a half second difference. That's pretty significant when you are in the 3-3.5 second range.
