If you&#x27;re going to fake it, just buy a SoundRacer accessory.[1]<p>Lotus put in a sound generator as original equipment on their electric prototype supercar.[2]  Not only did it make fake &quot;vroom&quot; sounds, <i>the driver had to shift</i>, with a momentary loss of power during shifting.  There&#x27;s no shiftable transmission on that car; it was all faked in software.  Everyone laughed at Lotus, and that idea went away, not to be heard again.<p>The age of &quot;vroom&quot; is over, now that no production gas car other than a few limited production supercars can out-accelerate Tesla&#x27;s family sedan.<p>Now <i>this</i> is a startup sound.[3] M1A2 Abrams tank, turbine engine.<p>[1] <a href="http:&#x2F;&#x2F;www.soundracer.se&#x2F;?p=98" rel="nofollow">http:&#x2F;&#x2F;www.soundracer.se&#x2F;?p=98</a>
