Key features included:
* Turbocharged V6 Engine: The heart of the Grand National was its turbocharged 3.8-liter V6 engine. Power output varied slightly year to year, but generally ranged from approximately 175 to 245 horsepower. Later models, particularly the GNX, boasted even higher horsepower figures.
* All-Black Styling: The Grand National's signature look was its almost entirely black exterior, including black paint, black wheels, and black interior. This monochromatic scheme contributed to its menacing and distinctive appearance.
* Performance Enhancements: Beyond the engine, Grand Nationals featured performance-oriented suspension, brakes, and other components designed to improve handling and acceleration.
* Limited Production: The relatively low production numbers over the years contributed significantly to its collectible status today.
* GNX (1987): The pinnacle of the Grand National lineage was the GNX, a limited-edition model produced in collaboration with McLaren Performance Technologies. The GNX featured further engine tuning, resulting in a substantial power increase, as well as upgraded suspension and other components.
The Buick Grand National is highly sought after by collectors and car enthusiasts today due to its combination of performance, unique styling, and relative scarcity. It represents a high point in the era of American muscle cars, blending performance with a distinctive and understated aesthetic.
