2013年,两起极不寻常的Model S碰撞事故导致车辆底部损坏,引发着火。遗憾的是,这些事故在全美新闻媒体上的头条报道铺天盖地,数量超过了去年仅北美就发生的20万起汽油车着火事故的报道。在这两起事故中,得益于Model S的安全性能,乘员均安全逃离。车载电脑提示乘员下车,在发现火情之前乘车人员便已离开车辆。然而,即便消防人员没有及时抵达,留在车内的乘员们也会受到电池组和客舱之间钢瓷防火墙的安全保护。

必须要指出的是,特斯拉从未发生过火灾引起的人员伤害(或任何类型的重伤或永久性伤害)。Model S发生着火的概率约为八千分之一,比汽油车的这一平均数低五倍;并且在火情发生时,Model S实际燃烧可能性也相对很低。然而,为了进一步完善我们的产品,几个月前,我们提供了无线软件更新,提高了Model S在高速公路行驶速度下的默认离地高度,这一举措将大大降低车底发生严重损坏的几率。

尽管如此,我们仍认为有必要将这一风险降至零,令驾驶Model S的车主完全放心。从3月6日生产的车辆开始,我们在车辆的车身都增加了三块车底护甲。同时,特斯拉也将在客户申请或常规保养时免费为已有车辆提供护甲改造服务。

When the California “high speed” rail was approved, I was quite disappointed, as I know many others were too. How could it be that the home of Silicon Valley and JPL – doing incredible things like indexing all the world’s knowledge and putting rovers on Mars – would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world? Note, I am hedging my statement slightly by saying “one of”. The head of the California high speed rail project called me to complain that it wasn’t the very slowest bullet train nor the very most expensive per mile.

You may have heard recently about an article written by John Broder from The New York Times that makes numerous claims about the performance of the Model S. We are upset by this article because it does not factually represent Tesla technology, which is designed and tested to operate well in both hot and cold climates. Indeed, our highest per capita sales are in Norway, where customers drive our cars during Arctic winters in permanent midnight, and in Switzerland, high among the snowy Alps.

This winter Model S took a trip to Baudette, Minnesota, one of the coldest places in the continental United States. Tesla engineers worked for days in sub-zero weather in order to put Model S through a rigorous set of demanding winter driving tests.

The Year of Model S is here. As we conduct quality testing, refine details and enter production of Model S, we are growing more excited every day to deliver this revolutionary car to our customers. Tesla’s Chief Designer Franz von Holzhausen and Vice President of Sales and Ownership Experience George Blankenship discuss how Tesla reimagined the sedan and produced a car with meticulous design and unrivaled driving dynamics.

From enhancing performance and tuning the suspension to quieting the interior and optimizing efficiency, Tesla engineers are applying knowledge gained from Alpha testing as they begin building Beta vehicles. Get a sneak peek at the first footage of multiple Model S Alpha sedans having fun together on the track.

Most visitors to Tesla Headquarters in Palo Alto probably don’t notice it. On the way to the front entrance, a building houses Tesla technicians and engineers busily testing and analyzing the Model S Alpha fleet.

Model S, engineered from the ground as an EV, is meticulously designed for superior aerodynamics, stability and handling, crash safety, performance and range. Before Model S enters production it will have been thoroughly tested using both computer simulations and test vehicles. Tesla will complete two vehicle testing phases, Alpha and Beta. The Alpha phase began in 2010.
