But those are the concept/show cars, there are more up-to-date info on some of these cars out there already. The Grand Prix GXP showcar uses the supercharged 3800 285 hp V6 but the 05 production model GXP has the 5.3 L V8 in it. Kind of misleading looking into these models and knowing different.

Actually, these are the versions of the Solstice and the G6 unveiled at the NAIAS last week. They have been on the Pontiac site for some time, but as concepts only. The images and specs that are up now are the actual details and pics of the production cars.
