Currently, the biggest success for the company is the Model S saloon (above), which followed the original limited-sales Tesla sports car, the first model from the brand established by tech millionaire Elon Musk.
A Model X SUV/crossover is due to launch this year, and the Model E may come in 2015.
Tesla offers longer range EVs than others in the genre, and expects to be able to bring down the price of its cars through development of better batteries and sales-scaled savings. The company is also investing heavily in charging stations around the US, and in European markets where it sells.
