$this->bbcode_second_pass_quote('Keith_McClary', '')$this->bbcode_second_pass_quote('dinopello', '')$this->bbcode_second_pass_quote('', 'R')eportedly Evernham has already addressed one issue facing the Tesla racers, or any electric car: It will need to make noise, both for the crew's safety and the fans' enjoyment. Supposedly Evernham has already purchased a retired Dodge Charger from Penske Racing, and will record the sounds the engine makes on a chassis dyno, and the Teslas will broadcast that sound through tiny but powerful speakers developed by another partner in the project, Bose.


Although lack of noise is both a plus and minus for electric cars in an urban environment as well. It's nice for the outdoor cafe diners but creates a hazard for pedestrians since you can't hear them coming you have to really pay attention with vision.

This does not seem to be April Fool:

Afterward, the automaker surveyed members of Mustang fan clubs on which processed “sound concepts” they most enjoyed.

That reminds me of my days as a little kid (maybe 5 or 8 ) wandering around our rural suburban neighborhood we would often stop to talk with the cool older teens who were putting in superchargers or otherwise "suping-up" their ride. One guy I remember was installing a "Thrush" muffler and on the box it said "The Sound of Power". Being smart alec little kids we started teasing the guy about that and how all his car had was the sound and no real power etc. He wanted to kill us, but he liked my sister. LOL.

With high tech cars carrying radars built in and self driving capabilities in their computers perhaps they could only have the fake sound on when a pedestrian or bicyclist were in danger zones leaving the car silent most of the time. That same detector might also alert the driver of the potential hazard with something akin to a nagging back seat driver. :-)
