Hey Blast,
That was almost spot on.
A typical lightning discharge has around 500 MJ
The energy for the car would be 23281 Amps * 220 Volts * 300 = 1,536,546,000J = 1537 MJ or about 3 average lightning strikes.
But the even a Deloran could go more than 166 miles on a full tank, so even this method is'nt was really that useful either

Great for time travelling though, Hmm I wonder if I could get some investors
