Capturing the rush of a jet-fighter’s sonic boom in its athletic stance and sleek lines, the Grand Prix “G-Force” was unveiled by Pontiac on Thursday, February 7, 2002 at the Chicago Auto Show. Configured as a 2+2 sport sedan, the G-Force previewed the next generation Grand Prix's design and performance characteristics. The concept G-Force came equipped with a 280 horsepower, supercharged V-6 engine, and speed-based electronic throttle control. Large Z speed-rated tires wrapped the 19-inch open spoke wheels.
