However, Musk adds in a separate tweet that the nearly 400-mile journey won't be possible soon, but "will happen long-term."

Separately, Bloomberg reported that Tesla Motors will help Chinese consumers trade in their old cars if they purchase a Model S. The company will deduct the value of the trade-in from the price of a new Model S sedan and team up with local used-car dealers to connect with customers in Beijing, Shanghai and Hangzhou.

Shares of Tesla were down slightly at $221.69 in Friday's premarket.
