just wondering why manufacturers use crank hp for numbers vs. wheel?

shouldnt it make more sense to show wheel becuase thats a standard all cars would compare too. i mean... 2 different cars with the same crank hp would have prety damn different wheel hp. wheel hp is one that matters....becuase thats what it puts to the ground.

wheel hp would take into account how much power crank has and drivetrain loss and etc...

the more i think about it, the less sense it makes to use crank hp.

The reason why they use crank is solely for marketing purposes, I'd assume. It sounds better when you say you get a car with 200hp for $X as opposed to saying you get a car with only 165hp for the same price.

Also it's so they don't have to use different hp ratings for manuals and automatics of the same make.. Otherwise people would be like..."hey, why does my auto make less power than the manual?"
