The Tesla taking off slowly out of the parking lot sounds not at all unlike that Prius backing out of a parking space right in front of Revelations Bookstore in FF the other day. They're both basically silent (until, of course, the gas engine fires up in the Prius). As far as I could tell, the only things making significant noise in the Tesla are the fans and electrically driven air conditioning compressor up front that are also used to actively chill the battery pack's circulating liquid coolant. > > Blind folks are complaining about the electric cars because of their > silence.

Tesla Roadster Electric Car Virtual Engine Noise - Lots of Fun! Now this one was good for a few chuckles. The National Federation of the Blind, among other groups, has lobbied hard for all electric cars and dual-mode hybrids to be equipped with noisemakers while in motion to aid the blind in traveling safely as pedestrians. BRABUS's solution for the Tesla's silent electric motor is to fit the car with what they are calling the space sound generator. The idea of driver-selectable engine noise programs, which are relative to throttle load, is just too fun. Want a big displacement V8 in your Tesla? How about the whine of a turbo rotary? BRABUS even offers otherworldly sounds called 'space' and 'warp' unlike anything coming from a fossil burner. The Tesla tuning package is available now, that is if you can get your hands on one of the rare $100,000 Tesla Roadster electric sports cars. If you don't make 8 figures, better get in line. The Very First Tuned Electric Car Comes From BRABUS: BRABUS Customization Program for the Tesla Roadster Official BRABUS Press Release The first tuned electric car comes from BRABUS: The first project of the future cooperation between Tesla Motors, Inc. and the new BRABUS business division Zero Emission <http://www.rsportscars.com/tesla/2009-brabus-tesla-roadster/#> celebrates its world debut at the 2008 Essen Motor Show. BRABUS (www.brabus.com) presents an exclusive customization program for the Tesla Roadster, the world's first electrically powered production sports car. The new BRABUS logo with added lightning bolt is the trademark of BRABUS Zero Emission vehicles <http://www.rsportscars.com/tesla/2009-brabus-tesla-roadster/#> . To give the sports car a more exciting sound the BRABUS electronics specialists have developed a `space sound generator.' The occupants on-board the Tesla Roadsters can choose from several simulated engine sounds including that of a typical V8 combustion engine, a racecar engine and two futuristic soundscapes named `Beam' and `Warp.' The volume of the sound is dependent on the momentary power output of the electric motor. ** Long article on the Tesla in August 24 edition of The New Yorker -- Tesla thinks it's going to sell a million units a year in a decade, hardly seems realistic (subscription required to read full article) abstract: http://www.newyorker.com/reporting/2009/08/24/090824fa_fact_friend <http://www.newyorker.com/reporting/2009/08/24/090824fa_fact_friend>
