By late morning, Tesla share prices were up around 10 percent.
On Tuesday's earnings call, Tesla CEO Elon Musk said the company is on track to produce several hundred new Model X cars per week by the end of the year. Musk also said he believes cars will become fully autonomous within 15 to 20 years, and that occupant-controlled vehicles "will be like owning a horse."
Cramer said "well orchestrated" statements like this make Musk come across as an "impresario."
"[Musk] could be on Broadway, he could run theme parks, he can do it all," Cramer said on "Squawk on the Street." "The confidence level is so repugnant. …"
Cramer said Musk's attitude is like that of Bill Belichick, coach of the Super Bowl champion New England Patriots, "in terms of 'Listen, I've got three rings, I'm not listening to you. I'm doing what I want.'"
Tesla did not immediately respond to CNBC's request for comment.
