The Buick GNX The Car That Humiliated the Corvette

In 1987, Buick did something nobody expected. The legendary Buick GNX took a turbocharged 3.8-liter V6 and turned an ordinary-looking American coupe into one of the quickest performance cars of its era — fast enough to challenge the Chevrolet Corvette. In this episode of Classic Machine, we explore the story of the 1987 Buick GNX: how it evolved from the Grand National, what made it so fast, why only 547 were built, and how this all-black Buick became one of the most collectible American performance cars of the 1980s. From its turbocharged V6 to its incredible 0–60 performance, the GNX proved that American horsepower was entering a new era.
