The automotive American dream came crashing down with the 1972 oil crisis. Muscle cars were dead, and for the next decade and a half, performance was nothing but a naughty word. The wind of change came with a turbo whirl, thanks to Buick and its experiments with forced induction—embodied in the Grand National.
The Buick GNX was a Grand National experiment pushed to eleven, with a slew of changes to all vital components. Inheriting the all-black treatment the Grand National, the GNX was fit for the it-villain of the era, Darth Vader himself. The Grand National and GNX reclaimed American performance, becoming icons of the post-muscle era.
