不怕麻煩的可以閱讀這些文章: IBM outlines how it helped Chevrolet with the Volt’s development IIHS says 2011 Chevrolet Volt and Nissan LEAF are practically as safe as larger cars Chevrolet Volt assembly plant begins construction of solar panel arrays Volt Safety System 首先就是volt很耐撞，撞了以后也沒發(fā)生起火或者其他情況。這個是Insurance Institute for Highway Safety (IIHS)做的，高速情況下裝一下，不會出現(xiàn)讓我們擔心的問題。 有個哥們挺有意思的，寫了這些： The Volt has three and perhaps four advantages over the Leaf. First it’s heavier. Rather than saying that the Volt weighs more than an Impala I think of the Volt as weighing more than a Mercedes E class sedan. You can’t say that about the Leaf. Volt竟然和奔馳E級的車一樣重，看來電池還是比較給力，Volt其實是一輛挺小巧的。 Second is that almost 80% of the steel in the Volt is high strength steel which protects the passenger compartment better (don’t know about the Leaf). 淚流滿面的80%的加強鋼，我很懷疑Volt如果不堅持徹底的降成本的話，怎么才能賺錢，用了多少好的材料和新技術啊。 Third is that the Volt has two more airbags than the Leaf — the knee airbags for the driver and front passenger. These ensure the occupant doesn’t slide forward and under the dash during a crash. 好多安全氣囊啊…… Fourth and finally the battery housing in the Volt protects the passenger compartment in a way that the Leaf battery pack doesn’t. Running into a Volt from the front or the side is a big like running into the end of an I-beam. 電池的耐撞性其實是GM花了最多的時間和精力的，在EV1就使用的布置，GM花了第一筆10億美金的收獲之一吧。 
雖然我對IBM很有好感，但是這句話還是太不給面子了：“It was a risk on their part because they are a very old company, but they needed to do it different and they did” 從這篇文章里頭，可以獲取不少的信息； 1.Volt里頭有個100+的電子模塊 2.Volt里頭總的模塊包含1000W行代碼，09年的車大概600W，05年240W，也就是說這車的軟件量非常大 3.原本預計開發(fā)周期為5年，實際的周期為2年5個月，很大的一部分原因是通過引入了Unified Modeling Language (UML)，采用了從系統(tǒng)策略模型直接至軟件的方法（這個我聽說過，不過完全不懂，有以前的xd是高手）。 4.測試步驟的簡化，從600=>400，三位數(shù)的測試步驟已經(jīng)讓我無從想象了。 最后一個有趣的事情是，在生產(chǎn)Volt的工廠里頭，安裝了太陽能的車棚，可以就近充電，挺有想法滴。
