The way car companies measure hp is at the crank, basically the advertised hp that every company uses. Hp measured at the wheels is the crank hp that is left over after going through the drivetrain. Due to friction and other forces hp is decreased as it goes through the clutch/flywheel, tranny, driveshaft, differential and eventually to the wheels. I'm not going to get too detailed, just do a google search for wheel hp vs. crank hp.
