Following a heads-up given by CEO Elon Musk last week on Twitter, the company has now shared some details of a new upgrade it will be making available for its electric sports coupe sometime in 2015. Together, the enhancements should offer a 40-50 percent range improvement and give Roadsters a 400-mile range under certain conditions.
