Everything burns. The only difference is with a electric car (or hybrid car) that is on fire is you have to worry about getting electrocuted.
When Toyota came out with their first hybrid car they sent out diagrams to all the fire departments (At least in Canada) of the cars electrical system with a "Do Not Cut In This Area" stickers so we wouldn't hit the main power supply lines. We sent a request to GM asking for info on their EV1 and were told it was not available .
