Within a year of release of the Model S, owners began expressing interest in learning more about how the Model S performs over time and miles and how their experience compares to what other owners are observing. As part of my work at Plug In America, I started a Nissan Leaf study 2012 and have an ongoing Roadster study. I've added a platform for Model S owners to report and share their experience, for the benefit of the owner community and the wider audience of people considering purchasing a Model S or other electric vehicle. My goal is to find answers to questions like these: What should owners, and potential owners, expect from the Model S experience? How does use of the Model S compare to other electric vehicles? How does the Model S battery pack hold up over time and miles? Does climate have an effect on Model S battery pack longevity? How does the Model S compare to other electric vehicles in battery longevity and major maintenance? I hope this will be a valuable community resource in both the near future and long term. Contribute to the Study I invite all Model S owners to participate in this study. I takes just a few minutes to fill out the survey form, available here: Plug In America Model S Survey Form The survey asks for your name, email and VIN sequence number, but keeps those fields private. Your private contact info will not be used for any purpose other than the survey (although I encourage everyone to join Plug In America's mailing list). Except for those private fields, all of the survey data will be available for others to examine and analyze. After you've filled out the form once, there's an update form you can use to correct or add a value, or to do an update with newer info, without filling in the values that haven't changed. Submit as often as you like, records are grouped by vehicle so there's no problem with having multiple reports on the same vehicle. Model S Survey Update Form Once your Model S is in the survey, you can sort the vehicle data by build date, miles driven, location, etc., to see how your car compares to others. I'm open to suggestion on how to best collect and present the data that matters most to Model S owners. Results To view results from the study, visit the Survey Results page where you'll find an overview of the participating owners and links to other survey resources. The Vehicles List page shows an abbreviated table of the survey data, sortable by various criteria, which provides an easy way to examine some of the most interesting information collected. Live Charts You can also view a page of charts based on the current data set. From the individual vehicle pages, there's a link to view a chart of that vehicle's reports overlaid on the most current reports for all of the other vehicles in the survey. Survey Data The full survey data set is available for download on the results page. Stay tuned for a report on the study results.
