Musk To Update Vision For Tesla At Investor Day

Elon Musk will aim to quiet any doubts about Tesla's standing in the electric car race on Wednesday when the serial entrepreneur convenes an investor day. Invoking his trademark flare, Musk promised to reveal "Master Plan 3" at the gathering, entailing "the path to a fully sustainable energy future for Earth," he said on Twitter in early February. The event, which will be held at Tesla's factory in Texas, will be webcast at 2100 GMT on Wednesday. "Since he is making promises for all citizens of the earth, and not only investors, there better be something pretty big," said Jessica Caldwell, an auto industry expert at Edmunds.com. Caldwell would like to see more clues on how Tesla plans to boost production.
