Facebook Inc. (FB) - Get Report COO Sheryl Sandberg vowed that the company would stay out of the tech vehicle race as an icebreaker to her speech in front of the country's most powerful automakers at the Frankfurt auto show Thursday. 

"I come with very good news. We're the only company in Silicon Valley that's not building a car," Sandberg said. The opening line was met with laughter and applause, according to Reuters. 

Sanberg did announce that Facebook will join an urban mobility test project in Munich with carmakers and startups.
