According to Autoblog Green, which got the story from Green Car Reports and ultimately, Auto Express, the Tesla Roadster which ceased production in 2012 will get a 400-mile range battery. You could say this is recycled battery news, and included is the longest-range li-ion battery yet may also get Supercharger compatibility.

The hint emanated from a Tesla shareholder meeting in June when CEO Elon Musk said the company was developing “a fairly exciting upgrade to the Roadster.”

Auto Express in turn revealed this will be a new pack.

“The Roadster had an old generation battery,” Musk said to Auto Express. “We’ll upgrade it to a new generation battery pack and it should have a range of about 400 miles, which will allow you to drive from LA to San Francisco non-stop.”

That’s a bunch more than Model S with 265 miles, and the 245 the Roadster could do.

The Roadster was built from 2008 and was Tesla’s proof of concept sold globally to somewhere around 2,400 people.

Sadly, the Roadster uses tech that is not presently able to be Supercharged. It would seem unlikely it won’t get this, and Musk said it will be “new generation” so what else would you expect? Would Tesla not give it Supercharger access?

Still unknown are costs of all this, or specific timing though Musk had said it would be during this year. Tesla characteristically offered no further information when asked by Autoblog Green.
