What sound should electric cars have ?

As noted in a recent Reuters blog article Gassing About Electric Cars, motor engineers these days appear to be faced with a peculiar problem - what sound to give electric cars?

Automotive industry participants obviously do not buy into the idea that we should have fewer cars on the road. More is better from their perspective. Anything else and even Government Motors will not be saved. Hell, the auto industry hasn't even liked the idea of moving to electric vehicles. However the industry has recently been forced to concede that at a bare minimum, a shift of the current fleet to electric vehicles will be necessary if we are to avoid a future not worth considering.


Now, as I have noted in previous posts, for various reasons I think the switch to EVs is just one very small part of the change that is necessary. In fact it may even lead to more difficulties down the road as the world gears up nuclear power stations to provide all the electricity necessary.

One thing I do find amusing is that electric vehicle designers are confounded by the noise of electric vehicles - or lack thereof. Why should it be a problem for a vehicle to be quiet? Well, not so surprisingly, automobiles are extremely dangerous. Those of us lucky to have good hearing have relied on it to save our lives. It is no surprise to know that deaths by automobile are highest among the elderly. The elderly cannot hear vehicles coming. Pretty soon we will all be faced with this issue. So what to do? Give cars artificial noise. Well this will bring a whole new dimension to the fight over noise pollution in cities. Not only are drivers making a lot of noise - it will be entirely preventable.

Meanwhile the USA has poured another billion dollars down the drain with their "Cash for Clunkers" program, while urban renewal projects that promote walkable cities are being knocked back due to lack of funding.
