Actually you don thave to have that many batteries as a range extender ,the electric motors already have more torque then a gas or diesel engine,the truck concept needs to be redefined ,I'm not talking about something that can go 200 miles on batteries alone ,I would say a hybrid or plug in with 40 mile range would be real useful . The battery pack weight can be strategically located for optimum traction and no need for a transfer case ,plus the benefits of regen braking ,the front can be conventional fwd ,there is a lot of room with this concept ,the prime mover doesnt have to be that big with the electric motors providing more then ample starting torque .I cant foresee that many problems for this vehicle fulfilling the the real world needs of perhaps 85% of the consumers ,I see so many huge trucks around here that do nothing and most fall short of 20 mpg .
