Tesla Motors to Release Details of Updated Roadster

CEO Elon Musk promised details about upgrades to the convertible, the company's first car, next week

Tesla's first car, the Roadster, will be getting some sort of update, Tesla Motors CEO Elon Musk pledged Monday, Autoblog reported.

"Roadster details coming next week," Musk wrote in a tweet, citing "several crises" that had delayed the announcement.

Currently out of production, the $100,000 Roadster was Tesla's first car, produced from 2008 to 2012 before being supplanted by the Model S sedan, which has become the default Hollywood status vehicle and sold an estimated 50,000 copies worldwide since its introduction.

Musk hinted earlier this year that upgrades were coming for the Roadster, possibly a battery upgrade that would extend its range from 245 miles to 400 miles on a single charge. Whatever the changes, they would presumably be retrofitted onto existing Roadsters.

But there has long been speculation that Musk also plans to relaunch the Roadster at some point.

The convertible is still featured prominently on Tesla's website and would fill a niche in the company's expanding lineup that will comprise the Model S, the much delayed Model X crossover SUV, arriving late 2015, and the Model 3 sedan, due in 2017.
