Under the Chassis: A Look At Tesla's Battery Shield

cartechboy (2660665) writes "Tesla said a few weeks ago it would add additional safety shielding to protect the battery of every Model S car on the road against damage from road debris. But it offered no photos of its update as it would look when installed--so one owner took his own. These may be the first detail shots of what the three different pieces look like. There's a half-round aluminum tube, a titanium plate, and a T-shaped section--and you can see how they combine to deflect and direct impacts to minimize damage to the battery. Do these updates look like they'll solve Tesla's problems?"

      Going around road debris isn't always the best decision, so I wouldn't necessarily assume the driver is being careless. Running over something which may do some damage to your vehicle may be a much better alternative compared to hitting the vehicle in the next lane or swerving into oncoming traffic. Both of which would risk harming others.

      Still, any vehicle with relatively low ground clearance is going to have trouble in this sort of scenario and the most anyone could claim is that the Model S is more prone to damaging expensive components. If that wasn't addressed, there could have been some liability issues in the sense that Tesla drivers may have a financial incentive to make a less safe decision in these sorts of scenarios. I think this, along with keeping the perception as the "safest car on the road" and general goodwill made it worthwhile to implement these design changes even though occupant safety was never really a serious concern.

      This has really been a non-story from the start. Tesla had a minor design issue on a first generation vehicle and have consistently done the right thing for their customers as well the rest of the driving public in every decision they've made along the way.

  17. I have to disagree with you on one point. by mmell · · Score: 1
    Any consumer available product should certainly be engineered to be safe when used as directed, and should be able to accommodate any reasonably foreseeable circumstance without itself becoming an undue hazard. In this instance, a Tesla Motors vehicle should be able to withstand any circumstance which might reasonably be expected to occur - within bounds of reason. I understand that in all instances of battery fires, the vehicle's occupants had ample time to exit the vehicle and watch their car burn up from the safety of the roadside.

    Incidentally, my (dinosaur powered) truck has a full skid plate under the carriage. That's an optional piece of equipment on my pickup, a vehicle which is even more likely than a passenger car to encounter operational conditions which include a greater chance of undercarriage damage (my truck's a 4x4 and was clearly designed with occasional off-road use as an intended capability). Mind you, I feel that my truck is quite well designed and is correctly engineered to perform its primary function adequately through many years of use; but Tesla is already exceeding even that mandate here, overengineering their product and even updating their design to accommodate "edge cases".

    (Oh, and what you refer to as the "Chinese way" - we call that planned obsolescence in this country - it's practically the holy grail of manufacturing design for many firms, nationality notwithstanding)
