Tesla Motors, Inc. Just Made the World's Best Car Even Better

Based on an exhaustive list of accolades, automotive experts and consumers have spoken: Tesla's (NASDAQ: TSLA  ) Model S is the best car ever built. But a few battery fires that occurred last year from high-speed impacts had investors worried that even the world's best car could be subject to a recall. Today, however, investors can rest easy. Tesla has addressed the issue of battery fires by adding a titanium underbody shield and aluminum deflector plates to the quarter-inch ballistic-grade aluminum armor plate that already protected the battery pack.

The technology
Tesla CEO Elon Musk took to Medium, a new social blogging platform founded by Twitter co-founder Evan Williams, to explain the new underbody protection.

The new battery pack protection consists of three layers. The first layer, a rounded, hollow aluminum bar, is designed to deflect debris. The second layer, a titanium plate, "which has exceptional strength-to-weight properties and is more commonly seen in aerospace or military applications," is designed to prevent damage. The third layer aims to eliminate any risk of penetration whatsoever.

"By this point, the vast majority of objects will have been deflected or crushed. For the rare piece of debris that remains intact, we added a third shield, which is a shallow angle, solid aluminum extrusion that further absorbs impact energy, provides another layer of deflection and finally causes the Model S to ramp up and over the object if it is essentially incompressible and immovable."

The new shield prevented battery penetration in 152 vehicle tests performed by the company. In fact, in some of the tests the underbody objects never made it to the existing layer already protecting the Model S' battery. Tesla went to extreme measures to inflict damage to the underbody, claiming it tried every worst-case debris impact it could think of. Musk described one of the extreme scenarios, saying it included "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." Musk says the impacts on driving are small, having a 0.1% on range and no effect on driving or handling.

All cars manufactured after March 6 have been outfitted with the underbody protection. Further, any owner can get the shield added to the battery upon request "as part of a normally scheduled service."

Why Tesla needed to go the extra mile
The Model S was already five times less likely to catch fire than the average gasoline car based on current statistics. Notably, however, there hasn't been any reported Tesla battery fires since the company sent an over-the-air update to boost the default ground clearance of the Model S at highway speeds. Even more, the National Highway Traffic Safety Administration has given the car a perfect five-star rating in every category and no serious injuries or deaths have been reported so far.

But adding further protection was a necessary step for Tesla. Not only does it effectively address public misconception of the safety of electric vehicles, but it also reduces the risk of a recall. Since it currently produces just one vehicle, a recall is a major threat to Tesla. Not only would it be a financial setback for the company, but it would also hamper its incredibly important public image. Investors seem to be pleased. The stock rose about 2.5% on Friday.

    I already sold Tesla but am just waiting for the bottom. Kudos on adding the extra protection.

    The bottom of the vehicle is the only place to put the batteries without destroying the people & cargo capacity. I see vehicles being taller, dual struts at each corner of the wheels, and powered running boards in future vehicles. This being an upgrade of the skateboard design. Weight won't be the primary concern, it'll be energy storage.

    Great, now charge shielded Tesla with an home EV solar charging system equipped with new ultra high performance Hyper X Solar panels. Hyper X Solar's N-Type, thin film passivated, tunneling junction architecture provides higher efficiency, a smaller footprint and a much lower cost which makes Hyper X solar's price/performance ratio hard to compete against when compared to the conventional solar panel manufacturers.

    Hyper X solar offers a better PTC to STC ratio "Real World" performance according to the California Energy Commission's performance rating listings than over 100 of SunPower's solar panel models.

    Hyper X solar also offers an incredible -0.27%/degree C temperature coefficient rating for awesome performance in hot/warm climates and best of all Hyper X solar systems are priced thousands less and even tens of thousands less on larger systems than a SunPower solar system.

    The biggest problem for Tesla isn't battery fires. It's the lack of sound. Because the vast majority of people who buy high-performance cars want their engine to rumble and snarl. Granted, silent acceleration is perfect for elderly Honda owners, and Lexus-driving soccer moms, but not for people who drive cars that pack 416 bhp, 442 lb-ft torque and run 0-60 in 4.2 secs. When you pay for that much power, you want to feel it.

    I like the idea of electric cars, but no electric built so far will really sell very well. Not for the PRICE. Some millionaires will buy one, probably to have a new toy" to show off to their rich friends. And a few dedicated enviornmentalists may buy one as a dedication to their "cause". But, you'll find very FEW average folks buying an electric car, due to the price AND an electrics LIMITATIONS. For instance, you can't take an electric car on a road trip or a vacation. It's range per charge isn't far enough, AND, there's NO place to re-charge it on the road !!!! And even if there were "charge stations" all over the nation, like our gas stations now, you are not gonna re-charge an electric cars batteries in 3-5 minutes, like you fill your current cars gas tank. It takes HOURS to re-charge those batteries. Totally IMPRACTICAL !!!!! Until engineers find a way to give an electric car a range of 4-5 HUNDRED miles per charge, and, the batteries can be re-charged in just a few minutes (maybe 30 minutes at most), until these improvements are made, NO electric car will ever be sold by the millions. Not for the price they sell for now. Because of all this, I would NOT invest my money in ANY electric car company.

    I can't believe how uninformed many of the people who comment on the Tesla are. If they had been paying attention, they would know the supercharger stations recharge in 30 minutes at no charge. I cannot afford a Model S, but hope to be able to afford the Model E when it comes out. However I live in Oklahoma and there are no charging stations here yet. There is presently scheduled to be one in Tulsa and one in Oklahoma City. Maybe someday it will be feasible in the less populated states.

    OMG, the idiots here should try out for the next Idiocracy movie.

    I just picked up my Tesla S P85 yesterday and had my first chance to try out the 0 to 60 in 4 seconds, the Porsche cornering, and the Lexus comfort, down Topanga Canyon Blvd on my way to the ocean.

    The experience was like having sex on wheels.

    It is literally everything the professionals say it is. It is the perfect car. Entering the corner at maximum speed, little over steer no under steer. Exit with immediate acceleration, no gas engine lag. All the while sitting in my comfortable Lexus.

    Is there any wonder that baby boomers are buying this car over a Corvette, Porsche or Ferrari? Who wants to crank ones back in those sports car seats when you can get the exact same sensation in comfort.

    You could not wipe the shitee eating grin off of my face. Case Closed!

    P.S. the jackass that said there are only 4 service centers really needs to learn how to read. Go to Teslamoters.com and read, please.

    Sure it is expensive, but way less than a Porsche Turbo, a Ferrari or a Bentley, and just as much FUN.

    Elon Musk's goal is to eliminate the incorrect perception that surrounds the electric car. With this retrofit, he has done just that. It wasn't good enough that it was the safest car EVER tested, so he went a step further to appease the false perceptions around its safety. What else does he need to do to appease the shameless ignorance that is represented by certain people in this forum? Make it cheaper you say??? Well, he is doing just that by orchestrating the launch of the biggest Giga Factory ever conceived...now. The battery technology is here already and is getting better always, as a MS 85 owner I can attest to that, and the cost of future models will drop considerably with the steps he is taking. Whether people with no vision for the future can see it or not, you will all be happily driving an electric vehicle in the not so distant future. Tesla is simply paving the way for necessary change.

    As for that "rumbling and snarl" sound? Last time I check, neither helped a car in crossing the finish line first. And the sound is nothing more than wasted energy. But I'm guessing you like wasting energy, as you're arguing with people that ENJOY the concept of the electric motor vs. the ICE. :-)

    Kgerbil1:That's a very unconvincing post from a non-owner, simply another reason to call people on all these posts. When you read posts made by people who actually own and drive Tesla cars you find they're level-headed and can talk about their ownership experiences without hyperbole. Never do they discuss how great it would be to see America's dealership network go away, never do they suggest that anyone who disagrees with them is a 'hater' or is in the pocket of the oil industry. I haven't checked this week but I bet existing owners are already looking into how much Tesla will charge them to fit shield's to a car that up till two or three weeks ago was purportedly the safest car in the world.

Where does he think Americans were when all that took place? Um, Africa? He has an ax to grind and when you invite him to speak he's going to grind it. Better to hear the history from somebody with no horse in this race, like the NY Times or Christian Science Monitor, both with reputations for reasonable objectivity. You Tesla fans love the David and Goliath aspect of the story. We all love the underdog but Musk and Tesla aren't the underdog you take them for.
