Keeping to a promise made earlier this year that “something cool” would be done with the Roadster, Tesla CEO Elon Musk tweeted Friday details are coming this week.

As usual, he gave few hints to make a perfectly reliable guess, but previous reports of what Musk also has termed an “exciting” upgrade have suggested a few possibilities.


Included could be a new battery retrofit for up to 400 miles range might happen as he told Auto Express UK, and the present car is not compatible with Superchargers, and suggestions have been Tesla could have a fix for that.

“The Roadster had an old generation battery,” he told Auto Express in October. “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.”

The California automaker has also said it wants a new super sports car, one that would need no excuses next to ultimate exotics, but this does not appear likely at this point.
