We were telling you recently about the Fisker Karma showing up in fake camo stickers as part of a PR campaign. This being the 21st century and all, video, as well as the still photos, was taken and now is available on YouTube. Said video is equipped with sound and has the Karma accelerating to the tune of something akin to twin turbines. Having heard previously that an actual running prototype of the car wouldn't be seen until closer to the sunset of 2008, we have to wonder what it is making all that racket powering this machine. Is it the rumored VW engine or an electric drivetrain? It doesn't exactly sound like the cross between a "Formula 1 car and a jet plane" that Monsieur Fisker spoke of during it's unveiling at the Detroit Auto Show. Perhaps it's just a simulation of a jet via speakers. Not being able to decide ourselves we leave it to you, the treasured reader, to let us know in your comments after viewing the video on the other side of the jump.

      There's a lot going on in the audio there.
      I definitely hear something that sounds like the gear whine of an electric power train (electric drives are loud because the gears are cut to a different shape to transmit power in two directions, unlike ICE gears).

      Most of the sound is just wind blowing over an un-sheltered mike.

      It could be the whine from the DC to AC inverter. These can make a lot of noise, are usually high pitched, and their frequency is related to the rotational velocity of the motor.

      That's my guess.

      Typical AC drive "Jetsons" sound.

      Google "EV1 goodies" and watch (listen to) the quicktime vid of the EV1 accelerating from inside the car: "Hear the unique sound as we accelerate to 40 mph."

      Very similar turbine like sound, minus the aerodynamic/tire noise in the Fisker clip.

      It really does sound like it is powered by jets

      Sounds like a curtis PMC 1.5khz whine

      No, seriously, I think there a jets driving that car. Sounds just like a MIG taking off. Maybe Fisker has a deal for surplus Russian jets.

      It's the combination of wind noise on the mic, the whine of the AC motor and tire noise.

      I'm pretty sure fisker has specifically mentioned external speakers to make noise for the "safety of the pedestrians". Because the car is very quiet.
