why do pickup truck manufacturers engineer their engines’ peak power so high in the rpm range?

854 views

Im in the market for a full size gasoline pickup for towing and hauling. Doing ALOT of homework, and most of the different truck brands have power bands at around 4000 rpm. (Lowest was ecoboost @3500) That seems awful high? Wouldnt you want to engineer the power band closer to 2500-3000 rpm where most tow rigs cruise at highway speeds for the sake of fuel efficiency?

No. peak power is used mostly when you are accelerating. Cursing at speed should not use peak power, accelerating to speed uses much more power than maintaining speed does.

Making the truck go from 50-60 mph takes more power than maintaining speed at 60mph does.

Also there’s the issue of hills to contend with. If highway cursing on flat ground required peak power, what would you do if you encountered a hill? Slowly lose speed?
