This is the big question on my mind - will Tesla make the new roadster a track monster? Porsche claims the Mission E will be a true Porsche capable of sustained track performance. Will Tesla prioritize this aspect of performance as well? Speculate.

They are spreading the power to three motors, which should help a bit. I think it also depends on if they are using PM (like in Model 3) or induction motors. PM would be easier to cool.This is the big question on my mind - will Tesla make the new roadster a track monster?

In one of the test drive videos, the driver specifically said that they were doing the 0-70+ sprints all night long, and that they could continue to do them without a problem. So, I think the answer is a guarded "yes".
My guess is the third motor is for gearing to reach higher speeds very efficiently.They are spreading the power to three motors, which should help a bit. I think it also depends on if they are using PM (like in Model 3) or induction motors. PM would be easier to cool.
Yes, but my Roadster's motor is already spinning at 14,000 RPM at only 125mph. Assuming a ball-park similar gear ratio, that would mean the new motors need to do in excess of 28,000 RPM, regardless of how much they are contributing to the forward motion of the car. That's one fast motor. Er, three of them.My guess is the third motor is for gearing to reach higher speeds very efficiently.
I haven’t been able to think rationally since the new Roadster rolled out of the Tesla Semi cargo trailer...I can't think rationally about what they've done.
I expect Tesla to show up at REFUEL to smash all the records. The question is in what year. The rational thing to do it would be to do it in 2019 or 2020 with a more production-ready car but Tesla isn't rational.This is a very key question. For track junkies (yours truly, included) this is the main weakness of the current Model S platform. Unfortunately, there is limited real-time telemetry on these cars from the standpoint of motor temperature, battery temperature and impedance, to understand the heat soak issue. Yes, the P100DL shows battery temperature when Ludicrous+ mode is engaged, but it would be useful to have this at all times, as well as motor vitals. What a car endures during hard lapping is a good bit more extreme than back-to-back 0-70 (or even 1/4 mile) runs, so I don't think we will know the answer until a prototype is put through its paces at Laguna Seca or another track.
I think they will. The S and X are family cars, this is a sports car. It's all a matter of a big enough dimensioned cooling system. 3 motors and 200 kWh battery will also help the cooling.
Track driving is far harder than those sprints, which like drag racing involved a cool off driving back to the start. On the track you are accelerating hard at all times except for a a second or two of braking before each corner.In one of the test drive videos, the driver specifically said that they were doing the 0-70+ sprints all night long, and that they could continue to do them without a problem. So, I think the answer is a guarded "yes".
The prototype Roadster shown at the Semi truck reveal had a small horizontal display embedded in the dashboard directly ahead of the driver and the passenger, it displayed the speed, PRND setting, Auto Pilot icon, TACC icon, and a thin horizontal bar whose purpose is unknown at this time.Currently the roadster has no dashboard to convey critical car information front and center to the track driver who must always be looking at the drive line through the corners.
Speculation, unless someone can provide a reference source that is reliable, like the guy giving the Roadster test drives at the event.I heard (or possibly imagined) that the thin horizontal bar is a G meter
It's in the following at time index 3:25.Speculation, unless someone can provide a reference source that is reliable, like the guy giving the Roadster test drives at the event.
