You will never ever get an electric motor to deliver the power a tubo-charged 500 hp Cat delivers. Long haul rigs run 24/7 from the east coast to the west coast.

You're right. You don't know.

"Today's diesel-electrics are impressive machines indeed. From the early days where a diesel road locomotive would be 1500-1700 h.p., we now see single diesels which have 6000 h.p."

Long Haul rigs will become a fond memory, and there will be fine toys and models built to commemorate them. The above will be the coast to coast option (the genset must be replaced by electric lines, of course..).. unless you go through Panama or the NW Passage. The 'diesel' is a gen-set, but the power to the wheels is from an Electric Motor.

A gypsy trucker is a man with a dream.

Plot:
A pair of big-rig truckers, one a crusty old veteran, the other a college-educated youngster, team up to haul cargo across the country.

Is Momma's boy, Obama, a gypsy trucker in disguise? Maybe? Who knows?

An electric motor doesn't need to deliver the same power as an ICE engine. They can deliver peak torque from zero rpm.
