A lot
That looks more like a non-Porsche tuning firm testing add ons it wants to sell on the accesories market than a serious Porsche product to me.
It's the same Porsche car that has been spotted on the Nürburgring testing with all the bits attached on the outside/bumpers etc.

Opinion: I'll take the "touring" verson without the wing please.

Opinion: If they are getting ~240 miles of range out of a 1,000HP Taycan, they aren't driving it properly.

Observation: The seats are lifted straight from 911 Carrera GTS with the "full bucket seats" option.

Observation: 251kw charge rate at 64% SOC? Did they change the battery chemistry too, because that's really good. As in hard to believe good.
I have to mention this one again, in case it got lost in the list:

One photo shows a 251kW charge rate at 64% SOC? Here is the zoom in:

Below is the charge curve graph from the InsideEVs June 2021 article. The only EV that can do anything close to 250kW at 64% SOC is..... absolutely none of them! The existing Taycan can pull only ~150kW at that SOC. Other sources say the Taycan can pull 175KW at that SOC. But 250kW? That's new.

I wouldn’t be surprised if they have removed load of protection logic in the BMS. It’s a test mule. They want to charge it fast to cover the test miles and won’t care about major battery degradation over a long period. So just whack the energy in fast.

This may be true, but it would be a surprise to me. I'd want my testing show whether or not the extra battery draw from the much more powerful motors was (or was not) harming the battery. Disabling charge rate protections would mean "changing two variables" here, meaning that if I did see a battery problem it would be difficult to figure out what caused it - draining the battery extra quickly or charging it extra quickly. All to save 5-10 minutes per charge - not worth it in my view.

It depends on the goals of the test. Looks to me like they just wanted to measure "user sentiment" relative to the "enhanced aero package".

Having said that, I am positive I have seen higher than 150kW at 50+ SoC, so I'm not quite sure the graph above is still "the truth". I have no proof, but will keep an eye out. (Well, I've never seen 251kW, either, so there's that.)

Lastly, Porsche mules usually don't have Stuttgart (S) plates - IME they're Boeblingen (BB) or Ludwigsburg (LB) depending on which research facility is doing the testing. I'm with @f1eng on this, it might be a tuner - too few instruments and/or cladding for a factory development vehicle. (And that garish wing - ugh 😖)

A bit of offtopic, but why does this chart shows taycan chargin 150kw from ~35%?
I usually charge at home but during my yesterday’s first long trip after buying my taycan I got flat 255-266kw charging rate during my short charging session. I needed to plug the car for 6 minutes and charged from 30 to 46%.

a friend of mine, senior engineer for major consumer electronics company, told me once - you can do anything you want to a LiON battery cell if you don't care about charging it again (or very many times).

all of these limits (temp, max charge rate, taper curves) are policy tools to elongate/mitigate LiON batteries from degrading - they are enforced by software not chemistry/physics…

I would be unsurprised if they remove/relax the BMS polices (since they are only in place for warranty reasons) on test mules to improve turn around time while testing…

you can do anything you want to a LiON battery if you don't care about how long it lasts.

I'm hearing from someone at the Ring that the GT will keep the 2 speed transmission, not Tri motor.
