The 1987 Buick GNX (Grand National Experimental) is a standout in automotive history, often regarded as one of the most significant performance cars of the 1980s. Developed as a special limited-edition model of the Buick Grand National, the GNX was designed to be the ultimate expression of Buick's engineering prowess. With its turbocharged engine, striking design, and impressive performance, the GNX quickly became a legend and remains a highly sought-after collector's car today.
A Bold and Menacing Design
The 1987 Buick GNX was designed to make a bold statement. It featured a sinister all-black exterior, including the grille, bumpers, and trim, giving it a menacing and aggressive appearance. The GNX's design was further enhanced by unique fender flares, functional hood louvers, and distinctive "GNX" badging on the front fenders and rear decklid. The car's wide stance and muscular lines added to its intimidating presence, making it instantly recognizable on the road.
The GNX rode on black 16-inch mesh-style wheels with white-letter Goodyear Eagle tires, which not only contributed to its aggressive look but also improved its handling and performance. The overall design of the GNX was a perfect blend of 1980s style and performance-oriented aesthetics.
Turbocharged Powerhouse
At the heart of the 1987 Buick GNX was a turbocharged 3.8-liter V6 engine, developed in collaboration with McLaren Performance Technologies/ASC. This engine was a significant departure from the traditional V8 powerplants found in most muscle cars of the era. The turbocharged V6 featured an air-to-air intercooler, a Garrett T3 turbocharger, and a unique engine management system, resulting in a factory-rated 276 horsepower and 360 lb-ft of torque. However, many experts believe these figures were conservative, with actual output closer to 300 horsepower.
The GNX's engine was mated to a 4-speed automatic transmission with a custom torque converter, designed to handle the engine's increased power and torque. This combination allowed the GNX to deliver exceptional acceleration, with a 0-60 mph time of just 4.6 seconds and a quarter-mile time of 13.5 seconds, making it one of the fastest production cars of its time.
Performance and Handling
The 1987 Buick GNX was not just about straight-line speed; it was also designed to handle and stop effectively. The car featured a performance-tuned suspension with stiffer springs, upgraded shock absorbers, and a unique rear suspension setup with a Panhard rod and torque arm. These enhancements provided the GNX with improved handling and stability, allowing it to corner with confidence and precision.
The GNX also came equipped with power-assisted front disc and rear drum brakes, ensuring reliable stopping power. The car's impressive performance and handling capabilities made it a well-rounded performer, both on the street and the track.
Interior Comfort and Style
Inside, the 1987 Buick GNX offered a blend of sportiness and luxury. The cabin featured supportive bucket seats with unique "GNX" embroidery, a leather-wrapped steering wheel, and a sporty dashboard with analog gauges, including a turbo boost gauge. The interior was designed to provide a comfortable and engaging driving environment, making the GNX suitable for both daily driving and high-performance fun.
Despite its performance focus, the GNX didn't skimp on comfort and convenience features. The car offered options such as air conditioning, power windows, power door locks, and an upgraded audio system. These features made the GNX a well-rounded and practical performance car.
Limited Production and Collectibility
The 1987 Buick GNX was produced in limited numbers, with only 547 units built. This rarity, combined with its unique design and impressive performance, has made the GNX a highly sought-after collector's car. Well-preserved examples of the GNX command premium prices at auctions and car shows, reflecting their enduring appeal and historical significance.
Conclusion
The 1987 Buick GNX is a true icon of the 1980s performance car scene. Its bold design, turbocharged power, and impressive performance set it apart from the competition and cement its status as a legendary muscle car. For collectors and enthusiasts, the GNX represents the pinnacle of Buick's engineering excellence and remains a symbol of the turbocharged revolution of the 1980s.
