Though hybrid tech is usually pointed out to fare better in heavy urban traffic than in highway, it makes sense to explore its regenerative braking as an alternative to traditional mechanical engine-braking setups.

Why all the talk of a diesel engine operating under a wide load range? It would operate similarly to a turbine in that it would only run when needed to charge the battery, and during that time would operate at peak efficiency.

I'd rather get a Diesel instead. Could even try some radial engine, much like a downsized version of the Guiberson engine used in Stuart tanks.

Another advantage of a hybrid design is to maintain cabin comfort without having to idle the engine.

All-electric air conditioners are already available and can be adapted into non-hybrid trucks too.

The huge drawback to a hybrid design is that it weighs a lot more, and that cuts into the max payload the truck is allowed to haul. Since the primary purpose is to haul a load, this is not an insignificant drawback.

Why not give BAS-Hybrid setups a chance? Even though they may not offer full-hybrid capabilities, their mileage improvement comes at a lower weight penalty.
