I afraid you not really got my point.
Altrough electric engines are have a big issue with battery capacity, but in exchange they are also much more effective, lasting, and less energy wasteful.
Whatever your point, making it about the noise is not the way to do it. It makes people believe you do not understand the engineering. Energy efficiency in cars has very little to do with the amount of noise they make.
There are in fact several major issues with currently available battery technologies. The Mercedes SLS electric is not the solution - at least not for the forseeable future. Yes it is an excellent showcase for what is technically possible, but at close to £400,000 is hardly a car for the people. Also, electric cars need regular recharging, which means plugging them into an electrical power supply for hours at a time - last I looked many power stations were still using fossil fuels. Then there is the cost - both financial and environmental - of making the types of batteries cars like the SLSe use. Finally, using battery power to go as fast as possible (which seems to be what you were originally suggesting) drains them very quickly - to the point that they are effectively useless as a very high performance power source. Batteries are just not the way to go as fast as possible for any length of time.
In the long term I foresee either some kind of hybrid power in which a very small petrol engine is used as a generator for the electric power source (hence my words about the BMW i8, which operates in precisely this way in one of its operating modes) or hydrogen power, which I've seen tested a few years ago but not heard much about since. If hydrogen fuel cells can be made practicable then this too is an extremely energy efficient option (until somebody decides that sucking up all the hydrogen is bad of course....).

All the above notwithstanding, the traditional petrol engine is not going away any time soon however much some amongst us would like it to.
