Uhh, you mean "legal" kW mobile?
The freebanders in the US typically run as much power as they can load on
their pickup trucks without breaking the axles. A mobile 50 kW is not
unheard of.
At 12 V, this power level is problematic, but with a second generator, trivial.
When I swapped the engine in my '69 Ford pickup truck (from 360 ci to 460
ci) I added a surplus second alternator that had an interesting
characteristic -- it could be run at almost any output voltage from 0 to 28
v, up to 100 amps.
Higher voltage alternators and generators are common in military and
flight-line surplus. It's a tight fit in many newer vehicles, but not
impossible if you're a decent bolt-turner.
With a higher voltage system in a new car, it still might not be feasible
to draw the current required for kW operation. You may be better off with
retrofitting a 20-year-old vehicle.
