The Economist:

PUT your foot down in a Tesla Model S and the experience is rather different to other cars. The usual exhaust roar is replaced by a hushed whooshing sound as the car accelerates rapidly—and relentlessly—thanks to the high torque of an electric motor making gear changes unnecessary because there is no gearbox. And inside, instead of multiple dials and switches, a large touchscreen dominates the centre console. Established carmakers have tended to make modest electric vehicles, usually small ones to eke out the range available from their pricey batteries. But it was Tesla, a Silicon Valley startup, which realised that many early adopters of new technologies are likely to be well heeled and would prefer a large high-performance saloon that is both luxurious and extremely high-tech.
 
 Why did Tesla act differently? For a start, it does not think of itself as a carmaker. “I see us more as an energy-innovation company,” says Jeffrey “JB” Straubel, the firm’s chief technology officer, and one of the co-founders of Tesla, along with Elon Musk, the chief executive. “If we can reduce energy-storage prices, it’s the most important thing we can do to make electric vehicles more prevalent,” says Mr Straubel. “Add in renewable power and I have a direct line of sight towards an entire economy that doesn’t need fossil fuels and doesn’t need to pay more to do it.”
