Model S 85 software enabled 0-60 speed increase?

[tskguy]

So,

I have been reading about the s 75 and 75d speed increase and I was contemplating if it would be possible for Tesla to increase the 0-60 time for older non performance model S 85's. I have read differing opinions regarding the older DU's are actually the same for the model S and a software only speed increase would be very possible.. I am sure it would help sell the large inventory of older CPO 85's!! The non AP 1 85 and p85's are pretty much going for the same price so it wouldn't impact the used market really. Thoughts?

I thought it was conclusive that P and non-P drive units are different part numbers. That was the case when I had my DU replacement... they had to get a P unit.

 

[tskguy]

Its interesting, I thought that as well.. But after having some discussions with some folks in the aftermarket electric car world said they were in fact the same. But that being said its complete speculation on my part and mostly just wishful thinking.

My understanding is that the very early cars 2012/13 had the same DU, but not any more. That was done initially to limit the variability of the production process

 

[tskguy]

OK this isn't looking good... I guess I have to buy a faster one
Its a huge bummer case I initially read that the insurance rates for a P85 were much higher that the 85..
So when looking for my CPO I focused on the 85... Once purchased I had my insurance provider run a P85 vin and the insurance cost was the exact same!! Grrrrrr.

I have a 2012. They had to explicitly get a P part #. I've read the reports from aftermarket tinkerers as well. I have not dissected multiple cars, so I cannot dispute. I guess it is possible Tesla used same DU with 2 part numbers. But it would be uncharacteristic of how they behaved in 2012/13. At that time, there was no talk of software limiting for manufacturing efficiency. It was more traditional manufacturing cost accounting: you get the part you paid for.

I guess Wk057 may be my only other option

it depends on the insurance company, some classify them specifically, some dont

I believe there was a thread where he made a regular 85 a p85 in fact

The different part is the inverter.

The different part is the inverter.

I think the different part is the firmware in the inverter.

 

[Demetraki]

Has anyone changed their 85 drive unit to a P85 drive unit?

 

[tskguy]

It would make sense that the inverter would be different.... I also read on here once that Tesla early one would install a P Drive Unit as a replacement once in a while depending on availability.

Just heard about this in the Tesla August newsletter which says - "new Model S and Model X 75 kWh vehicles received an over-the-air software update and now have improved performance, with the ability to accelerate from zero to 60 mph one second faster."

Am I right that the upgrade does NOT benefit the Model S 60 even though it has the same hardware as the 75?

Sooo... are 75 owners noticing a difference here? Is it worth buying an upgrade just for the acceleration even if the extra couple miles of battery isn't important to me?

"new Model S and Model X 75 kWh vehicles received an over-the-air software update

I think you missed one word in that. Is the Model S 60 a new Model S 75? (The new 75s had new hardware that the OTA update "uncorked."

We know from other threads that for this claim Tesla considers 75kWh cars made on/after around June 19th, 2017 as "new".

75 and 75D variants increased performance from July 1st - software and hardware improvements?

Here's a lengthy thread about the updates on the 75s. Still conflicting information and no one knows for sure yet.

Upgrading a 60 to a 75 will not currently enable any performance increase. But it could be enabled by Tesla at little expense to them. Likely the biggest expense is warranty liability. Tesla is currently upgrading all of its inventory cars, whether or not they have the new, post mid June, drive unit.

...Still conflicting information and no one knows for sure yet.

We're pretty clear on what Tesla has upgraded. But Tesla is extending those upgrades over time and we don't know how far that will go for free and when, if or how far back they might offer paid upgrades.
