Tesla Motors beat all expectations to post a profit instead of the loss Wall Street analysts had predicted.The real story is the success of its Model S, the most technologically innovative electric car ever built. Tesla sold 5,150 units of Model S, instead of the 4,500 it had planned. Tesla CEO Elon Musk is the business innovator behind this.

Technology innovations are really behind the success of Tesla. Just one of them, the use of small batteries instead of the large ones preferred by other companies, made the Model S a more powerful, sleeker and safer car.Its battery swap could take this concept further, as it allows recharge within 90 seconds.

In india, Model S will be a sure success, if it is launched after 2 years since there is no infrastructure for electric cars here.
