Prior to the GTO reintroduction in 2004, Pontiac
showcased a more extreme-looking concept in 1999, with blocky styling
far removed from the Holden Monaro body used in the current GTO model.
the concept car sported 19-inch wheels in the front and 20-inch wheels
in the rear, the car had no engine or drivetrain to power them, and was
strictly a design-concept piece.
concept GTO pays homage to Pontiac's muscle car of the 1960's and 70's.
GTO styling cues include a side profile with hints of the famous "Coke
bottle" shape introduced on mid- to late-60's' models. The rear quarter
windows are reminiscent of 1968-69 GTOs. A hood-mounted tachometer pod
like the one that first appeared in 1967 is part of the package.
However, the large, 19-inch-diameter front wheels, 20-inch rear wheels,
and ultra-low profile, 40-series tires are much different from the
14-inch bias-ply US Royal Red Line tires included in the original GTO
option package. The car's computer-generated interior uses high-tech
materials such as aluminum, and the center section of the dashboard is
an extension of the hood and painted to match.
