I think the hope is the Porsche Taycan will be a legitimate track car. Teslas are still known to overheat, and I have yet to find a single example of someone tracking a Tesla for even 5 laps in a row (I am aware of the Model 3 Track mode, but either nobody is using it or it doesn't work).

EDIT: Found this article:

https://insideevs.com/news/367599/video-tesla-model-3-track-...

So it is doing significantly better than what I originally stated, although apparently you're only going to get about 30 minutes of driving before you have to recharge. That takes a few minutes with gasoline, and a few hours with electric (at 80% you won't even last the 30 minutes).

There are some interesting comments on that article, someone calculates the car will only last about 15 minutes on a really demanding track.



I will definitely concede that Tesla's cooling is insufficient for track use.

Track mode pre-cools the batteries when you enable it (among other things), which allows you to go for longer, but it only delays the inevitable.

I'm interested to see if the Model S Plaid edition and Roadster 2.0 have better cooling to make them better on a track.


I think it's just really hard to keep their batteries where they need to be. In order to get better performance/range, Tesla chose NCA batteries.

The problem with NCA is it is more volatile, and if it overheats it literally explodes violently. I am not saying this is insurmountable, but looking at the progress Tesla is making versus the reality of how long you can drive the cars hard, I think Teslas might never be great track vehicles.

Although every EV car will have this problem to some extent, so it's not limited to Tesla. If Porsche can't figure out how to cool an EV well, then it's a long way away because they are famous for their engine cooling technology.


What’s the importance of trac performance in this context?

The Tuscan also quickly runs out of charge at top speed and then be forced into a car or battery swap.

PS: At the extreme Indy cars average 1.92 MPG, batteries are just a poor fit for any kind of endurance racing.

OP said the Model 3 was a superior vehicle, I was stating why it might not be.

The meat of my comment was about batteries overheating, not being drained. We have no idea how well Porsche will cool their batteries in their car until someone has had a chance to test it.

> PS: At the extreme Indy cars average 1.92 MPG, batteries are just a poor fit for any kind of endurance racing.

This is a disingenuous comparison. We are talking about street vehicles you or I can buy and drive on public roads, not track-only vehicles that cost more than a house anywhere but the Bay Area.

I also think it's disingenuous to call a half hour of racing an endurance run. I think it's more accurate to say batteries are a poor fit for racing with the exception of drag races.


Hill climb races tend to be a few minutes and would work just fine with electric vehicles. EX: https://en.m.wikipedia.org/wiki/Pikes_Peak_International_Hil...


I concede, it would be really awesome to watch EV cars attempt Pike's Peak. I'm actually surprised how well it seems to cater towards their capabilities.

(the Volkswagen 2018 full drive)


bronson beat me to it, EVs have now set the Pike's Peak record, and ironically it's a VW (just not one they put into production). Here is another video of the VW, the first result for "EV pikes peak":

No, that is definitely not the hope. The Taycan weighs over 5000 pounds. It will not be a track car.

The hope is that the build quality will be typical Porsche. Whereas the build quality and ergonomics of a Tesla, well hasn't been seen for 30 or even 40 years, at least not in the West.
