Tesla will supply about 1,000 powertrains for the Smart ForTwo EV, Elon Musk, the company’s chairman and chief executive, said at a conference held in conjunction with the North American International Auto Show in Detroit. The electric Smart cars with Tesla components are due to arrive in late 2009 or early 2010.

If the matchup is a success, the deal “will expand to tens of thousands of vehicles a year,” he said.
