Just how is a car with an ultracap in it as a power source going to generate an EMP?

Because it's a capacitor and able to release large amounts of electricity in a very short period of time.

A HERF generator is similar to a simple radio transmitter. The very acronym HERF stands for High Energy Radio Frequency, indicating that it probably generates radio waves with large amplitudes and high frequencies. To output such large amounts of energy, there must be a way to store it temporarily, since a battery's current outputs generally don't cut it. The most practical way to store energy temporarily in order to release it in one large pulse is to implement a capacitor, which basically stores electric charge. The capacitance requirements of a fairly powerful HERF generator are about 10,000 Farads. Finding a single capacitor with 10kF capacity is damn near impossible, but you can wire a number of capacitors with lesser ratings in parallel in order to achieve 10kF.

Here's another reference for HERF technology that could readily be built and/or utilized on the cheap were high powered ultracapitors available to the public:

I believe it was someone else on this thread who brought this issue up and opened my eyes to the potential threat. HERF EMP vulnerabilities are a relatively unrecognized threat and having literally millions of potential HERF devices driving around is something our electronic infrastructure really needs to deal with.

I have a bit of training and experience in the field of security, so this got my attention.

Other than that, I love the idea of Ultracapacitors. Quick charge, long duration and recycle life. THAT would truly be a major paradigm shift in vehicle technology that would sink fossil fuels (if the price is reasonable).
