Tesla is confident in everything it does. Back in 2014, for instance, the company made a bold move to extend the warranty on the battery pack – an eight year, infinite mile warranty – to the powertrain as well. Now, a blog post by Elon Musk on July 17, 2015, indicates the company is working on making a powertrain that will last at least a million miles. Only time will tell if he will ever meet that goal, but working toward that goal has led Tesla to develop an advanced smart fuse. This so-called smart fuse has allowed Tesla to increase battery output by 200 amps. Channeling this extra amperage to the powertrain makes the Model S hit a 0 to 60 mph sprint in only 2.8 seconds.
