Have our trucks got too much power yet?
I've often thought about all the energy being wasted with braking applications and exhaust braking on down grades. It's only a matter of time before our rvs will have electric drive axles to help hold...

I think the point is that a 5.0 liter turbo diesel designed to make 300 hp will use considerably less fuel moving a pickup truck down the highway at 60 mph, where the power output is only about 60 hp, than will a 6.7 liter turbo diesel designed with a low compression ratio to allow for high boost levels and a 475 hp out put doing the same job.
I suspect, you won't find that much difference when those engines are mounted in the same truck.
Now if you compare a light 1/2ton to a 1 ton dually, you are likely seeing the result of the extra weight and aerodynamics.
