Having said that, cars catch on fire. Porsche had the 991.1 GT3, and many other automakers have had incidents (both electric and ICE). It could also be a one off situation, or even something started the fire inside the car that was unrelated.
I'm confident Porsche will do what's right.

All cars ICE or EV have a massive amount of highly volatile potential energy stored in a very concentrated small space.
This can happen to all cars and does not usually represent a systemic flaw. It will be interesting to follow the investigation.
In the case of EVs only thing that any auto OEMs can do is to develop systems to reduce the probability of thermal runaway from happening through damage or defects in the battery.
As more EVs hit the streets it will be interesting to see the data as if battery fires are going to pose a greater than normal risk compared to traditional ICE vehicles. One thing is for sure is this is not very good PR for electrification.
As more manufactures electrify it will be interesting to discover the safety margins of pouch vs cylindrical cells as it relates to usage in a high vibration high mechanical stress environment.
Pouch cells offer the advantages of greater packing density and much better modularity. The disadvantage is that a plastic pouch does not have its own structure and is more prone to damage than a much stronger aluminum cylinder. Thus is physically more susceptible to mechanical damage.
The other issue is cell isolation. Pouch cells are generally much much larger than an 18650 cell. If one cell has an internal short due to a defect it will release all of its energy and produce a lot of heat and will cause thermal runaway of the entire battery pack. Whereas a single 18650 with a defect will release a lot less energy and will more likely isolate itself from the rest of the battery pack.

Maybe they shouldn't have sourced the batteries and charging system from that hoverboard manufacturer. How many have they put into service in Germany? Seems they would want to spend a year selling them there first before selling in their #1 market.
Doesn't matter. Saw one at the Porsche Experience Center. It's stunning.

I can remember a long period of time that "new" cars didn't spontaneously burst into flames. Plenty have gone up due to shoddy maintenance and repair after being driven for a decade but "new" cars going up in flames seems to be a problem that needs to be looked into currently. As a car owner for almost 4 decades none of the ones I have owned just burst into flames while sitting unused. Not even the ****ty used ones I bought.
