Tesla unveils cheaper model aimed at mass market

Tesla unveiled a new, cheaper model of its electric car aimed at the mass market on Thursday, taking more than 115,000 orders in the past 24 hours -- nearly three times the number of cars it produced in all of last year. The company said orders were piling up even though the new car won't be available until late next year. "The total number of orders for the Model 3 in the past 24 hours has now passed 115,000," said company founder Elon Musk at a presentation of the new car.
