Tesla Tries An Engineering Solution To An Emotional Problem

It’s always wonderful to see life imitate art, particularly when the “art” is an Ayn Rand book. Remember that part in Atlas Shrugged where Hank and Dagny ride the first locomotive over the Rearden Metal bridge? (Um, that was a spoiler, sorry about that.) Now we have the real-life Hank Rearden (or is that Howard Roark?) in the form of Elon Musk, showing the world how his technological ideas are stronger than the media’s ability to destroy them.



You can read the whole story on Tesla’s website, but it boils down to this: To address concerns about impact-related battery fires in the Tesla Model S, the company will be fitting (and retrofitting, to existing models) titanium underbody plates to the vehicles.

During the course of 152 vehicle level tests, the shields prevented any damage that could cause a fire or penetrate the existing quarter inch of ballistic grade aluminum armor plate that already protects the battery pack. We have tried every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac.

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.

The final paragraph is the best part:

As the empirical evidence suggests, the underbody shields are not needed for a high level of safety. However, there is significant value to minimizing owner inconvenience in the event of an impact and addressing any lingering public misperception about electric vehicle safety. With a track record of zero deaths or serious, permanent injuries since our vehicles went into production six years ago, there is no safer car on the road than a Tesla. The addition of the underbody shields simply takes it a step further.

Brilliant, really — and stupid. Given that this happened at the same time that revelations about GM’s concerted efforts to deny responsibility for the Cobalt ignition switches, this out-in-front response to potential issues is refreshing. But the fact that Mr. Musk allows his withering contempt for the media, and the general public it serves, to shine through undisguised doesn’t bode well for the company’s future. Remember all the misery that Ayn Rand’s heroes suffer, when the media-governmental complex decides to lean on them?

    I like the idea of Tesla more than I actually like the Tesla itself. After driving it I still think it needs a lot of work and it needs a price chop of at least $25,000 and a minimum range of 350 miles on a charge. The stock price is just laughably and insanely overvalued. Personally I think the car is safe and just fine.

      @Kaosaur >> The average Model S sold is about $95,000 nicely loaded and as far as I am concerned it is not a $95,000 car, it is barely a $75,000 car. Correct pricing is determined by supply and demand. If you're running a 2 - 3 month order backlog, then your product is not overpriced.

    For those following along, the first Tesla fire in the wild happened just days after Tesla "created" it's NHSTA rating of a 5.3 (or was it 5.6) and said no other car was rated safer - ever - an then in a dig to other electric and series hybrid makers went on to say, no Tesla has ever had a fire in an accident. It couldn't have been a week after the first Tesla burned. The Maginot line will never be breached. The Titanic is unsinkable. A DC-10 can never have a triple hydraulic system failure.

      @u mad scientist "> The Maginot line will never be breached." "It wasn’t." Not directly, I suppose... :-)

  • Rochester I'd rather have a slow-as-mud Plymouth Prowler than this thing. At least the Prowler looked cool.
  • Kcflyer Don't understand the appeal of this engine combo at all.
  • Dave M. This and the HHR were GM's "retro" failures. Not sure what they were smoking....
  • Kcflyer Sorry to see it go. The interior design and color options in particular are rare in the industry
  • Wolfwagen Here is my stable. not great not bad I try to do as much as possible. I work for an Aftermarket automotive parts company so I can get most parts at a discount.i try to do as much of my own work as possible. My wife hates that I spend time and money fixing the vehicles but she doesn't want car payments either so...2019 VW Atlas 50K (wife's) Only issues so far were Brakes and normal maintenance.A Bad Cat Converter which was covered and a replacement of the rear bank head gasket which was a manufacturing defect due to improper torquing at the factory. All under warranty2003 Saab 9-5 Arc Wagon (my DD) 116 K picked up used last year. Replaced Struts, brakes, hatch struts, motor mounts, D/S swaybar link, Timing belt, water pump and thermostat Power steering pump Fuel pump, Both Front window regular rollers, Heater core and cabin air filter. Oil and transmission changes. Love the car but Saab/GM packaging is a nightmare.2005 Cadillac Deville (former DD now Son # 1 DD) picked up used 5 years ago with only 47K now 83K Plugs, coils, P/s pump, Water pump, hoses, P/S lines (mechanic job) evap valve, brakes, Front brake calipers and rear brake calipers. Currently has oil pan gasket leak - looking to have a mechanic do that2009 Mini Cooper (Daughters dd)picked up 2 years ago 67K Brakes and thermostat house to clear check engine light2001 Mazda Tribue (Son#2 dd) 106K picked last summer after he severely damaged a 2004 Hyundai accent.
