I love all the uneducated comments about "it can't work because
There are very large/heavy/fast electric vehicles already. With a vehicle this large and one-off, you could do some pretty cool stuff:
two (or more?) redundant electric motors for front vs rear drive
inductive charging (just park next to a transformer somewhere
regenerative breaking for increased range in urban areas
extreme high efficiency solar cells for maintaining charge/powering internal devices
gas/diesel backup power plant
Also, with advances in materials, it's possible that armor isn't nearly as heavy for *better* protection.
The real limiting factor will be finding all of the components made exclusively in the US.
