Tesla, in its stock market debut this year, set aside $50 million in shares for Toyota to purchase. Tesla has also purchased a former Toyota factory in Fremont, Calif., where it produced cars in partnership with General Motors Co.
Tesla's only current model in production is an electric roadster that sells for more than $100,000.
