Ok, that's not a jet vehicle but it will go like it has a jet! 
Through a friend who has to install ultracapacitors for a project at work, I stumbled on the data of these ultracapacitors:

Look at the last unit. This is a unit in which a lot of capacitors are combined. During 1 second it can deliver 3930 amps at 125, let's say 100, volts!!
That is around 400 kW (=510 hp) for one second
, out of 58 kgs (120 lbs). Combine a few and you have enough power to make a 1/4 mile run.
The only problem I foresaw was the huge size and weight of the electric motor, till I found this thread :
