P85 vs P85+

I am sure this has been covered over and over again, but scrolling through the first couple pages I didn’t see anything. I have my deposit down and looking to finalize the order Thursday between the P85 and the P85+. Is the cost difference worth it? I would love to hear feedback as I have only test driven the P85...if there’s a thread that already covers this topic (I'm sure there is) a link would be awesome as well. Looking forward to joining the family…cheers!

Hi,

This forum really needs a good search function but at least you tried. There have been a few posts here but also over the the populat Teslamotorsclub.com forum. Here is a good one where a new owner of a P85+ compares it to an M3:

The search function there works so you can find a few more about the differences.

Generally speaking the performance plus option makes the car respond better to changes in direction and owners often say it reduces the floaty feel when curnering or making lane changes without negativly impacting the ride quality.

Thanks for the response. I did read that article as well as the one that compares the P85+ to the Panamera and I actually used to own an 11’ Alpine White m3 sedan with every option under then sun and loved it. A keyword search function would be awesome and as we all know (being members of various other car/hobby forums) would keep the repetitive nature of some posts down :)

Repetitive, you say?

How's that for repetitive?

One thing to note about volkerize.com is that it is a day or few behind the times, as it depends on Google's crawlers to update. The most recent posts won't show up.

I started one of the threads about this and have not seen anyone do a direct in depth comparison between P85 and P85+ on this or any other thread. Not looking for comparison between MS and another make although that is also fun.
It would be really nice for someone to do this and report about the real differences.

Not many of us have one of each.

Oh well... we will just have to wait.

+1

The problem, obviously, is getting extended access to both, preferably simultaneously.

When TSLA hits 200 I'll buy a P85+ just for this purpose:) The misses will have to suffer in the plain jane P85

Shakespeare... I had a P85+ owner in Palm Beach post that he/her would be interested in getting together. I'll let you know when we set it up.

I spoke to the guy's at Menlo Park Tesla Service and basically the P85+ feel's a lot like the P85 but without the floating feel when you lane change or take a turn hard. You feel more of the wheel's on rails effect when moving around in the P85+. I will get a P85+ loaner as soon as they have one.

I own a P85+ in the San Francisco bay area. I did not get to test drive a P85 so I can't compare. The car is amazing and absolutely sticks to the ground like glue. The only floating that occurs is me flying around in my seat.

Just to clarify, the main (only?) difference between P85 and P85+ is the $6,500 Performance Plus Package, yes?

I currently have a p85 and was one of those people that just missed out on p85+ by couple of days. My question would be. When they have after market parts can I buy parts worth of $6500 to make it better or same performance?

Todd;
Yes.

rchiang;
Partial (80%) upgrade is ~$13,500. Some changes must be done in production.

Like the thicker sway bars which you can't remove once the car is built.

Can a P85 owner And a P85+ owner get together and give us a report.

Brian H: When I said "Aftermarket parts" that doesn't include dealer product....

I think $6500 is a lot of money for just parts. I've done an engine swap in the old days and I paid 4k plus had enough money to buy all the sway-bar, stabilizer bar, and etc. Don't know just because of the type of car they will mark up the price, I'm sure product is low cost.

Labor and tuning. Then markup.

As for me all I need is parts I'll do most of my labor, but tuning need machine to turned.

just wait till someone compares the P85 with the P85+

I'm sure lolchampcar will chime in soon but from what I recall reading from his posts is that the only thing the factory "retrofit" kit comprises of are the stiffer bushings, wider rear wheels, wider rear tires and more performance oriented tires. While the factory installed kit also adds a thicker rear sway (or both?) and differently valved shocks as well.

At least this is what I recall. Hopefully the "experts" will verify my recollection.

Cheers!

Sorry. I know that doesn't answer the OP's comparison question. Just want everyon to realize that it's not possible to make a P85 into a P85+ without buying one to begin with.

Who knows what the aftermarket can do though. I'm sure there will be some cool upgrades soon enough as long as you don't care for your warranty!

First, I've found out the local owner has a P85 and not a + so I will not be getting together with them this week to do a back to back test (bummer).......

From Tesla Engineering-
P85+ retrofit (call it +r) was a cost/benefit exercise. There is way too much labor to install the relatively inexpensive sway bars in the field. The dampers are expensive and very time consuming to swap in the field so there is a double whammy with those.

To recap-
+ production has updated rear suspension bushings (I was told ALL bushings which means lower a-arm inner bushings, toe, camber and torque link bushings), re-valved dampers (increase bump and rebound), same spring rates, thicker front and rear roll bars and 1/2" wider rim / 20mm wider tires in the rear with the tires being Pilots instead of the normal Contis.

It is my understanding that an order must have 21" wheels ($3,500 I think but am not sure) and the $6,500 + package to get the production + package.

The field update comes with the wheels and tires along with swapping out all the rear suspension arms to get the stiffer bushings. From a cost/value standpoint, this is what I came up with-
lower a-arms $550 each (based on F10 M5 arms which look almost identical to MS)
camber links $220 each (Tesla price... bought some)
torque links $150 each (guess)
toe links $200 each (guess)

The total for both sides would be $2,240. Normally labor equals parts so that brings it up to $4,480 then you need to add an alignment. When you toss in margin for the package (in addition to that already wrapped into the parts) you can see how they get to $6,500.

The +r package requires the purchase of the wheels/tire package. My test drive was with a Conti shod P85. My car was delivered with Pilots. I was very pleasantly surprised by a significant increase in stability of the car on Pilots so I would say the tires are a sizable part of the improvement.

I can see by some of the comments above that there are others like me that prefer to do their own work and do not like to toss cash in the trash. I would prefer to purchase the suspension bits and install them myself. When my Contis (if I had them) wear out, I would simply replace them with Pilots or another good performance tire with better value. I have read posts suggesting Tesla will not sell the parts by themselves but only in a complete package (read - forced to buy new rims and tires even if you already have 21s) with Tesla doing the install. The comments included something about liability which I find difficult to understand and people have already changed rims and tires on their own without impacting Tesla's liability.

When I got my car I started down the path of reducing rear camber to increase tire life. I then started looking into bushings knowing they were too compliant. Tesla came out with the + package so I backed off those efforts. Now that it looks like there will be some road blocks to a sensible implementation, I have picked back up on those efforts. I believe the toe, camber and torque links can be done with aircraft style angular misalignment ball bearings and should have a set of camber links done this week (links built, just waiting on bearings and spacers). I'm also ordering in M5 inner a-arm bushings to see if they will fit MS. Pull up a F10 M5 lower a-arm and compare it to MS. You'll see why I think that is where Tesla got their suspension inspiration. With luck, there should be a way to do this in a cost effective way.

Again, my first choice would be to buy the parts from Tesla. I continue to hope that they will be supportive of this type of owner enthusiasm but then my dad used to say "you can hope in one hand and spit in the other..... see which one fills up first" :)

I'd like to be able to order the + handling package on a standard S - I'd rather the cornering ability than the extra acceleration.

If someone has the P85+ all they need do is schedule with their local Tesla dealer/service center to borrow Teslas loaner for an hour or so. Bam, side by side comparisons. You never know, the people at Tesla might be willing to volunteer as the second driver (I know I would }BD ).

Thanks for chiming in lolachampcar and confirming what you've found.

It would be great to be able to buy this stuff individually for installation on a regular S or even have an S+ as Mark E suggests. I wouldn't be surprised if that happens in the future when parts aren't so scarce.

Cheers!

I drive a Mercedes S600 2007,should i buy the Model S P85 or P85 +
