Tesla CEO explains the Roadster’s delay

A durable transmission that can maintain the original claims of 0-60 mph in 4 seconds is just not ready. In the interest of getting cars into the hands of owners, the company has decided to deliver the Tesla with a transmission that enables the car to do 0-60 in 5.7 seconds. Once the company has perfected a higher performance transmission that enables the Tesla to achieve 0-60 mph in 4 seconds, it will then retrofit all the delivered cars with the new transmission at the company’s expense.
