He only said it would be on the ring not that they were trying for an "official" record. Isn't it open to the public most days?
Why go through the expense of sending a car over to Europe from CA if open track is not available? If they just need to drive the track during public days, then why not just use one of the cars in Europe? I am sure there are P100DL loaners around.

HUGE difference running a P100DL and a current P RAVEN
Safety is required for a track like Green Hell. Roll cage is a basic safety device nearly all manufacturers will put in their cars when attempting track records. It's a track that do claim a number of life a year, and is very unforgiving to mistakes.

Ring makes available exclusive time for companies wanting to set records or test their cars without traffic. Weather is often an issue, as getting clean laps, in cooler weather, and without rain or fog is challenging in that region of Germany.
Either Tesla has reserved some time, but under a different name, or that it just is going to bring one of their cars out to get some initial ring experience. Maybe introduce a professional driver to the car to get feedback to further develop a record challenger.
Interesting coincidence that Tesla has been sending out OTA updates to their Ravens, enhancing handling at speeds over 100 MPH. Somebody at Tesla must be at least doing some development of their new adaptable suspensions to provide enhanced stability and performance.
Tesla can get millions of inexpensive publicity by simply putting their car on the track at earnest speed.
While they are there, perhaps they will also get some autobahn high speed data runs on the Ravens.

Good point. But still, why bother shipping a car over just for public day? The track specifically says no record attempt during public sessions.
It is from the production model. Other than the roll cage, there has been no other change.
There is touristenfahrten allow you to drive your own car on the ring. But it's not the full lap, only BTG times. And it's not reserved so you have to deal with the traffic of all those other cars. So there is no comparable lap record possible.
However if Model S can do a 7:30-ish BTG I will still consider it a good news.

If you have a 12V DC to 120V inverter for your car, ever tried plugging it in backwards and see if you get 12V back? You won't. It's different electronics that convert DC to AC than back. From wikipedia on inverters:
They are different designs, different pieces of hardware. What you have eluded to when EV's use their drive hardware for AC charging, it's likely them use their regen rectifier, not their drive inverter.
A massive Tesla win is unlikely (obviously that's just my guess, given an unmodified car) and, perhaps, unwanted.
If Tesla ran a 7:49, they could walk away heads held high.
Then Taycan sells to the track fans, and Model S to the regular drivers.
Everyone wins, lots of EVs get sold.

Sorry man, the drive inverter in a Tesla is about as similar to a plug-in ac inverter as a nuclear plant is to a briggs & stratton 10KW generator. Teslas use the same circuitry for both drive and regenerative braking, and unless design decisions were purposely made to limit the braking, it should be capable of braking as hard as it can accelerate.
I am an electrical engineer, and formerly worked at Enphase, a solar inverter company. Our inverter was bi-directional, and used in our storage product (a competitor to Tesla's power wall). One side hooked to AC, one side hooked to DC, and you could command the control circuitry to push power either direction, using the exact same transistors - just the timing was different. It could move the same number of Watts in either direction.
I have not seen schematics for Tesla's inverter, but strongly suspect it uses a similar topology. There is no reason for different power hardware for drive and regen.
The Magic of Tesla Roadster Regenerative Braking

How does it work?
Due to the simplicity of the AC induction motor’s single moving part, the Tesla Roadster does not experience the engine compression braking of a traditional internal combustion engine (ICE). Instead, the advanced algorithms in the motor controller give it complete control of the motor torque for both driving and regenerative braking. A torque command is derived from the position of the throttle pedal. The motor controller converts this torque command into the appropriate 3-phase voltage and current waveforms to produce the commanded torque in the motor in the most efficient way. The torque command can be positive or negative. When the torque serves to slow the vehicle then energy is returned to the battery and presto - we have regenerative braking!
This article also talks about the trade offs they considered when choosing the amount of regen.

Then why do all of their videos clearly state that it was a prototype?
If Tesla's Planning a Nurburgring Lap, They Forgot to Tell the Nurburgring
Does not surprise me one bit if Elon didn't actually schedule anything.
If one is going to launch an insurance product, one might actually have a person or two check the rates to see if they make ANY frieken sense before making it public.

Likely because they are not official in production yet. In my industry, a product is a prototype until it enters production for customer delivery, even if the production product is the same as the prototype.
