This could be the truck of the century especially if Ford can increase its mpg efficiency. I still cannot understand why a car or a truck cannot have a high mileage gear for low load-interstate driving. I know all of the engines produce enough HP to do this on the level interstates. I do believe it is possible.
Detroit is braindead when it comes to half-ton trucks. You can't work out of those trucks when the bed is 55-65 inches off the ground. The beds on the 79 Ford half-tons that we work out of are 44" off the ground and racks are 71" high. The new trucks are decent if you just want to haul three or four garbage cans to the dumps...

Well, when you run at the limits of your engine's power, your vehicle is a dog on hills, and if you ever needed a burst of acceleration, you would get nothing.
If there were some sort of pressure storage system, it might be possible. Years ago a Minnesota engineering class built a vehicle with regenerative braking and valving that enabled the braking wheels to act as pumps. They would pump pressure into essentially a SCUBA-tank-like reservoir. This reservoir could be tapped when you needed a burst of power.
