> We believe these changes will also help prevent a fire resulting from an extremely high speed impact that tears the wheels off the car, like the other Model S impact fire, which occurred last year in Mexico. This happened after the vehicle impacted a roundabout at 110 mph, shearing off 15 feet of concrete curbwall and tearing off the left front wheel, then smashing through an eight foot tall buttressed concrete wall on the other side of the road and tearing off the right front wheel, before crashing into a tree. The driver stepped out and walked away with no permanent injuries and a fire, again limited to the front section of the vehicle, started several minutes later. The underbody shields will help prevent a fire even in such a scenario. That is not just PR. That is damned amazing engineering. That's the kind of description you get out of an episode of Knight Rider, not something in real life. That's clearly evidence that these cars are designed and built to an amazing level. |

Well, yeah, it's exactly that: a description, and a fantastic one at that. It makes no guarantees or even assertions about the efficacy of the changes. Instead, it plays up this explosive scenario, then concludes that they hope the changes will help prevent fires.
And, there's a reason it's not written in technical, engineering jargon with test results, etc. Instead, it reads like a Hollywood screenplay. Judging from your comparison to Knight Rider, it appears to be working.
>That is damned amazing engineering
So, I mean what engineering are you hailing as amazing here, with regard to the new announcement that was gushed over higher up in the thread? The part you quoted just briefly references bolting some plates on the undercarriage amidst a lot of hyperbolic crash talk from the pre-plates days.
Sure, there can be great engineering alongside good PR. The auto itself without the newly announced iron man suit is an impressive piece of engineering.
I'm simply saying that I wouldn't gush over the new announcement. The guy walking away without injuries was pre-crash plates and we have no evidence that the plates will actually help or to what extent. Just sensational, cool-sounding descriptions. There are a lot of things for which Musk deserves credit as a visionary, but this bit of PR could have just as easily been the brainchild of a relatively astute PR staffer talking to an engineer over lunch.
