There's only one way to show first responders how to get occupants out of a Tesla Model S, and that's ripping one apart.

The car's electric drivetrain and massive battery pack means there's more involved than grabbing a Sawzall and going to town. So Tesla put out a training video for fire crews and police showing how to safely dismantle the all-electric sedan. It's a combination of pure engineering porn and gut-wrenching destruction.

If the Model S is your dream car, be prepared. The video above is not for the squeamish.
