I love my car.
I phoned in my upgrade request for my order from an S85 to a P85D on 10/11, the day after the event. I took delivery on 12/29. I know about software and electricity... lithium-ion batteries, discharge characteristics, motor power. I'm not a dope, and I didn't expect that the car would be able to make it's combined HP rating at
every SoC, temperature, pavement condition, etc. but it was within the realm of possible. Knowing what I do about the type of batteries involved, it's very reasonable to think that it could achieve this for short periods of time. Passing! Launching! Fun!
I was super happy to get my red monster after a many-month wait. By that point they had made it pretty clear that it was a work in progress, and I'm an active cheerleader for the brand and the ideas behind it -- so I cut the car and the company both a lot of slack. When I took delivery, it was really cold on the east coast -- batteries don't work well when it's really cold, so that must be part of it, right? The software was obviously not finished, as the car simply
ate electricity, so maybe that was part of it, too, right? Besides, they said they were working on it, and even promised at the end of December that we'd see performance improvements (especially at "high speed") via
software update soon, "above what anyone outside of Tesla has experienced to date". Awesome!
Time passed.
I've had my car for nearing up on a year now and over 20 thousand miles, and it's hands down better than any I've ever owned...
but it's really come as a surprise to find out that it will not meet some of it's specs under any conditions. It's beyond obvious now that as-built, it's simply not capable of meeting the numbers that were widely touted at the time by the media and Tesla employees alike. Car buffs, experts and noobs... these numbers were was all anyone was talking about. I know I'm not alone here. To those that ordered much later, or never did, I don't really expect that you'll understand just how
pervasive these particular numbers were and how
excited everyone was about it all.
In retrospect, it's easy to see why things didn't turn out the way they wanted: The fuse and contactors simply couldn't (reliably) handle the amperage they were hoping to push through them with a software change. The ratings for the fuse and contactors were not a commonly known fact until very recently. Had I known that the parts in question are limited to ~1300A, I wouldn't have upgraded my order -- the math just isn't favorable to meeting the expectation. It's common knowledge (now) that these are the parts that need to be changed out to deliver what's now known as "Ludicrous" mode. The real-life performance characteristics of the "Ludicrous" cars are more in-line with the expectations that surrounded the P85D at it's release, so it's natural for some disappointment to set in. These parts are buried in the battery pack and I'm sure they're a bitch to replace... special tools, training, time, etc. Joy.
I understand that any potential remedies will come at a cost to someone -- software isn't enough to fix this problem. Handing my car back isn't something I want to do - did I mention that I love it?!? - but neither is selling it to replace it. Legal remedies -- well, I'm just not that guy. $5000... plus another $2500, feels like a lot of loot to pay for something I thought I
already owned.
I don't think that people who find themselves unhappy with the situation are wrong to be. People that are fine with it, well, I'm cool with you, too.
