Tesla is currently the most valuable American car company, worth $53.5 billion at market close today — about $3 billion more than General Motors. That’s despite sales that are nowhere near American auto giants.

Tesla sold just over 22,000 vehicles this quarter. That’s a little more than 1 percent of Ford’s 1.7 million in sales this quarter and a little less than 1 percent of General Motors’ 2.3 million.
