A glimpse into the future from the first electric racing cars

The second season of Formula E, the world's first championship with fully electric vehicles, starts at the end of October 2015 in Beijing. Enthusiasts of the sport hope it will serve as an important technique to boost the electric car market, which will influence the future course of the entire automotive industry.
We are told that it is exciting as there is no fuss like in today's racing and that it is clean for the environment. It will help improve today's electrics and make them even faster with their incredible E-tron like torque . I will agree to a point but what car enthusiast doesn't like to hear the roar at every press of the throttle of a V8 or doesn't crackle and flame from the exhaust or the sound of a 12 cylinder Ferrari?
They even say that 10 to 20 years from now the smell of exhaust will be like the smell of cigarettes in a restaurant. Uh, that's... encouraging.
What do you think about the future of motorsport? Are electric sports cars exciting or a dull future for racing?
