今天的节目中将介绍，奥迪研究自动驾驶汽车的乘坐体验……大陆集团开发自动着色车窗玻璃……还有，减少柴油车排放的新方法

大家好，我是王丽莎。欢迎收看Autoline中国频道，在这一期的节目里我们将为大家介绍当今汽车行业里非常重要的一些技术进展。

研究自动驾驶汽车内饰
奥迪透漏他们正在研究自动驾驶汽车的乘坐体验。奥迪与位于斯图加特的弗劳恩霍费尔（Fraunhofer）研究所联手，制造了一个自动驾驶汽车的模拟器，希望可以搞清楚如何设计内饰，才能把自动驾驶汽车，变成一个惬意的工作场所。这个模拟器可以显示电子干扰情况、把车窗变暗、改变背景噪声和灯光的颜色。同时，研究人员会监测乘员的大脑活动，还有相应的反应时间和所犯的错误情况。结果并不出人意料，在干扰少的环境中，如果车窗变暗，加上较少的电子信息，乘员可以更加放松，因此可以更好更快地完成任务。这项研究是奥迪“第25小时”项目的一部分，该项目旨在研究在自动驾驶汽车中，如何可以更加有效地利用时间。

大陆集团研究自动着色
早在几年前，奔驰轿车就具备这一独特功能，即可以一键改变车窗的玻璃颜色。它的原理是，电流通过车窗玻璃夹层中间的薄膜，促使分子向一起聚集，进而改变了玻璃的透明度。现在，大陆集团把这项技术向前推进了一步，使之自动着色。当汽车停着的时候，玻璃完全着色，以确保内部凉爽。当你走近汽车的时候，玻璃变成完全透明。当汽车在路上行驶时，甚至是拐弯的时候，玻璃的着色程度都会根据情况自动调节。不论是在明亮的阳光下，还是穿越昏暗的隧道或者地下通道，它都胜任愉快。另一个独特的应用，是在风挡上方设置一个遮光带。这是一个聪明的办法，可以让驾驶员的眼睛避免阳光直射。不过考虑到自动驾驶的未来，这个遮光带将有可能覆盖全部风挡。还有一个好处，就是不需要空调拼命工作了，汽车制造商甚至可以考虑，把空调的规格和尺寸降下来。

佛吉亚系统强力减少氮氧化物（NOx）的排放
全世界一些国家的政府和一些大都市正在对柴油车狠下杀手，来减少氮氧化物的排放。现在，韩国的首尔正与法国供应商佛吉亚合作，对2万台巴士和商用车安装佛吉亚的Amminex系统。Amminex将向尾气中喷射气态的氨，将可以使氮氧化物的排放量减少99%。大多数柴油车使用汽车尿素（AdBlue），它是液态的，喷雾进入尾气中，也很好，但是并没有那么高效。佛吉亚表示，Amminex系统在发动机温度较低的时候效果最好，这样它十分适合应用于巴士和商用车上。

福特推出共享自行车服务
越来越多的的汽车公司扩展他们的服务，涉足移动出行。现在福特公司与共享自行车技术的领导者Motivate联起手来，他们在旧金山湾区推出共享自行车项目，取名为GoBike，今天正式上线。使用者可以使用“福特通行证”（FordPass）这一APP在网上预订，也可以直接去站点租车。福特说，到这个夏季末，他们可以提供3500辆自行车供租用，到明年年底他们将设置550个站点，提供7000辆自行车提供租车服务。

特斯拉的估值为什么那么高？接下来，John McElroy先生将分享他的看法。

特斯拉一如既往地向市场报告财务亏损和大把烧钱的消息，然而，它的股票价格却在一再刷新记录。这一情况让大多数汽车专家们彻底地找不着北了，因为他们无法解释这是为什么。好吧，我來解释一下，这一切是如何发生的。

硅谷的风投人士告诉我，处在传统汽车行业的人们正在使用错误的评估指标。他们说，不要看底限，而要看上限，也即这家公司带来了多少收入。不要看净利润，而要看毛利润。

当你使用这个方法评估，特斯拉的业绩真是棒极了，不是一般的好。它录得120%的收入增长、142%的毛利润增加。这样的增长指标正是亚马逊、苹果和谷歌早期的情形。这就是为什么风投界兴高采烈地把更多的金钱投向特斯拉的原因。与此同时，传统的汽车制造商在最好的情况下，只能录得一位数的增长率。

所以，如果你想知道特斯拉未来将走向何方，只需要关注其上限。最新的预测说，特斯拉的股价将还会再增长30%。

今天的节目就到这里。我是王丽莎，感谢您收看Autoline 中国频道的节目，我们下一期再见。

On today’s show… Audi researches the autonomous in-car experience… Continental develops windows that tint on their own… and a new way to reduce diesel emissions.

Hello, I’m Lisa Gray, welcome to Autoline China, the show that covers some of the most important new technologies in the automotive industry.

RESEARCHING AUTONOMOUS INTERIORS
Audi revealed that it’s researching the in-car experience in a self-driving car. The automaker, along with the Fraunhofer Institute in Stuttgart, have created a simulator to mimic autonomous driving to better understand how the interior can become a better workplace. The simulator can show digital distractions, dim the windows and change background noise and the color of the lighting. At the same time, the researchers measure participant’s brain activity, in addition to reaction times and errors made. Not surprisingly, in a less distracted environment, with dimmed windows and limited digital messages, the participants were more relaxed and able to finish tasks better and faster. This research is part of Audi’s “25th Hour” project to study how time can be better used in an autonomous vehicle.

CONTINENTAL DEVELOPS AUTOMATIC TINTING
Mercedes has been offering windows that tint at the push of a button for several years now. When an electrical current is applied to a thin film between the panes of glass it causes the molecules to clump together, changing the opacity of the glass. And now the supplier Continental is taking the technology a step further. Automatic tinting. When the car is parked, the windows are at full tint to help keep the interior cool. As you approach the car, the windows go clear. While driving down the road, even when turning, the tint will adjust automatically to conditions, whether it’s bright sunlight or going through a dark tunnel or underpass. Another unique application is a strip at the top of the windshield. It’s a clever way to keep sun out of the driver’s eyes, but in an autonomous future it could be applied to the entire windshield. Another benefit is the air conditioning system doesn’t have to work as hard. Automakers could even reduce the entire size of the air conditioning system.

FAURECIA SYSTEM GREATLY REDUCES NOx  
Governments and municipalities around the world are cracking down on diesel vehicles to reduce NOx emissions. Now Seoul, South Korea is working with French supplier Faurecia to install its Amminex system on 20,000 buses and commercial vehicles. Amminex injects gaseous ammonia into the exhaust stream and can reduce NOx emissions by as much as 99%. Most diesels use AdBlue, which is sprayed in as a fluid, which is good, but not as effective. Faurecia says Amminex works best at low engine temperatures which makes it ideal for buses and commercial vehicles.

FORD LAUNCHES BIKE SHARING SERVICE
More and more car companies are expanding into mobility services. Now Ford is teaming up with Motivate, a leader in bike-share technology. They’re launching a bike-sharing program in the San Francisco Bay area. Called GoBike, the service starts today. Users can register online, use the FordPass app, or just walk up to a station to rent a bike. Ford says by the end of the summer it will have 3,500 bikes ready for rent and by the end of next year will have 7,000 bikes and nearly 550 stations.

Coming up next, John McElroy explains why Tesla is valued so highly.

Tesla continues to report big financial losses and it is burning through
cash. Yet, Tesla’s stock continues to set new records. This completely
confounds most automotive experts, who cannot explain why this is happening.
Well, I’ll tell you why it is happening.

Venture capital investors in Silicon Valley tell me that people in the
traditional auto industry are looking at the wrong metrics. Don’t look at
the bottom line, they say, look at the top line, which records how much
revenue the company is bringing in. And don’t look at net profits, they say,
look at gross profits instead.

When you measure it this way, Tesla is performing spectacularly well. It
posted a 120% growth in revenue, and a 142% increase in gross profits.
That’s the kind of growth that Amazon, Apple and Google posted in their
early days. And that’s why the venture capital community is gleefully
pouring more money into Tesla. Meanwhile, the traditional automakers are
only posting single-digit growth, at best.

So if you want to know where Tesla is headed in the future, just keep an eye
on the top line.  The latest forecast predicts the stock price will go up
another 30%.

And with that we wrap up today’s show. I’m Lisa Gray, thank you for watching.
