He was just asking why they don't give you the rwhp of a car instead of the flywheel hp. That really isn't a stupid question at all. But they aren't just "getting away with it" because the flywheel hp rating is real even though by the time the power gets to your wheels it is significantly less. I'ts not like they just guessed and are false advertising or something. Just a different way to rate hp

Rating the engines at the flywheel is also easier for the manufacturer, can you imagine how many different variations there would be with different options, gear trains, tire sizes and such.

Its important to realize they are rating the engines, not the car, so yes, that is a good point. The engine stops at the flywheel, so that's where you kind of have to define the "engine HP rating." And of cours eyou are right, if they rated the Hp for the car they'd have to give you all these different ratings depending on options, which trans, whether you have air or not, etc.

^^^^In addition to that post I thought I would add that you could have a 1000 hp stang and it could run 15's because you have like 2 tons of bricks on it. the hp is of the engine that is why a 260hp eclipse and a 320hp mustang are the same or semi close to it anyway is because eclipses are much lighter than a stang.
