the battery charger engine is a twin cyl. -- hmm...
here is a cutaway - the entire unit body is CF and made in Wash. - who wants to join me for some dumpster diving?
the CF unit body is so strong it does not need a central pillar
may have a nice fun rear wt. bias...
also note how all the wt. is down way low below the flat floor - should have great handling to go with the high torque
