I pointed to automotive reliability and durability testing - My Nissan Leaf Forum at Drive Unit failure symptoms and thresholds for replacement - Page 5 and I'm not sure if people paid much attention or visited some of the links. Post links, articles, figures about automakers and their long-term reliability and durability testing here. I'll start. How Engine Development Teams Ensure Durability â€“ Feature â€“ Car and Driver | Car and Driver Blog - talks about beating the crap out of engines Nissan Proves Commercial Vehicle Toughness in Extreme Arizona Desert - YouTube mentions how Nissan loaned this AZ company the NV 3500 van and they were putting on 7500 miles/week, 80K miles in 3 months. They showed a van w/557K miles. Some quotes typed up at Official Tesla Model S thread - Page 270 - My Nissan Leaf Forum. Robots Are Test Driving Your Next Car - My Nissan Leaf Forum is about Ford using robots to help test cars on the track. Here's a few more about Ford: On the (very bumpy) road with Fords robotic almost-self-driving test track truck | ExtremeTech http://www.at.ford.com/news/cn/Pages/How%20Ford%20Uses%20Robots%20in%20Vehicle%20Testing%20Assembly.aspx -- too bad a lot of videos here no longer work. I found this: Building the million-mile car | Fox News yeah, yeah Fox News The doors opening/closing 84,000 times figure is also mentioned at Testing | Alliance of Automobile Manufacturers AGES ago, before GM's bankruptcy, I recall reading an article (that's LONG gone off the web now ) where it mentioned that GM changed their testing procedure from testing parts until mileage warranty expiration to testing until part failure. I guess the old procedure might help explain why the 3 GM vehicles we had long ago weren't so reliable... Inside Ford's high-tech climate chamber - Never thought about ICE air filters possibly getting clogged w/snow before. The first few minutes of Translogic 185: Ford Autonomous Testing and Virtual Manufacturing has a bit more details on Ford's testing w/cars driven by "robot".
