For 2006, two additional colors were added to the line up, Spice Red Metallic and Brazen Orange Metallic, while Midnight Blue Metallic and Yellow Jacket were dropped. Changes for 2006 included revised blacked-out tail lamps, illuminated steering wheel radio controls and an interior power door lock switch. The climate control button for the A/C also had the word "Defrost" added to it for the 2006 model year.
On February 21, 2006, General Motors reportedly told dealers that it would halt imports of the GTO in September, making 2006 the last model year for the current GTO generation. This should have come as no surprise since this generation GTO was only intended to be produced for those 3 years from the beginning of the program.
The final production numbers of the 2006 Pontiac GTO are 13,948 cars, an increase from 11,069 from the previous model year.
The last Pontiac GTO, which was also the very last Monaro-based coupe produced, came off the assembly line in Australia on June 14, 2006.
Total production for all three years was 40,808 vehicles.
