Pontiac GTO specs: 2004-2006

Pontiac GTO specs: 2004-2006

The new GTO was based on the Holden Monaro with each one being imported from Australia. As time passes, the traditionalists are becoming more accepting of the ’04-’06 Goat, though the first one is the least desirable. The 2004 GTO’s were considered too bland in appearance and too tame, even though the LS1 had 350 hp. Things quickly changed for 2005 when a revised front end and a more powerful LS2 engine (400 hp) were fitted. As a bonus, the front brakes were straight off a Corvette these two years.


GM Platform: V-body

Trim Levels & Packages:

  • base (2004-2006)
  • Sport Appearance Package (2004-2006)- adds front
    fascia extensions, side rocker moldings, rear fascia extensions with custom dual/dual exhaust tips,
    unique spoiler, and a grille insert
  • W40 (2004 only)- Seats were embroidered with red ‘GTO’, unique ‘Pulse Red’ exterior paint color, gray instrument cluster. The final 794 ’04 Goats had this package, probably due to news of the better engine and body effects that were coming for ’05.
  • BZJ (2005 only)- This is just a hood scoop delete option. But, there were few takers on this option since most people think the scoops on the ’05s make them look that much better than the flat-hooded ’04s. This is one to watch in the future.
