Do these magazines inflate their HP and torque

just wondering if the new vehicles horepower ratings are also inflated. We recently tried a 2010 ram on the quarter and it ran 90 mph....seems rather low for a 400 horse hemi.
My lil red ran 15.3 at 89 mph years ago with the original 220 horse 360.

it just seems like the new stuff has big numbers but no performance to match these high horse numbers ... hell my new 2011 Journey is rated at 285 horse!
