25% of hp lost at wheels??

I heard that at the wheels, your car has roughtly 25% less horsepower than at the crank. is this true? is it really THAT much power lost?

its more likely about 20% max

20% is still a lot

what would make that less?

all I can think of is lighter driveshaft.

it might actually be more than 25%


but think about how much your motor loses just because of the weight of your pistons/rods etc?

when it says 200hp isn't that taken into account because that's 200hp at the crankshaft rite?
