Tesla Motors Inc (TSLA.O) saw strong orders of its Model S sedan tied to the launch of its sports utility vehicle, relieving some concerns that the larger car might siphon away sales, Chief Executive Officer Elon Musk said on Friday. “We were worried that maybe there would be some cannibalization of Model S orders,” Musk said, speaking during an event in New York held by SolarCity Corp (SCTY.O), a solar energy company of which Musk also serves as chairman.
