GNX Detroit: The Legacy of Buick’s Dark Horse

The Buick GNX, a high-performance version of the Buick Grand National, was a collaboration that involved McLaren Performance Technologies/ASC for its final assembly and tuning in Detroit. This iconic car, produced in limited numbers in 1987, quickly became a symbol of American muscle and technological innovation. The GNX Detroit connection is crucial to understanding its performance capabilities and collectibility.

What Made the GNX Special?

The Buick GNX, short for “Grand National Experimental,” was more than just a Grand National with a few tweaks. Buick partnered with McLaren Performance Technologies/ASC to create a true performance machine. McLaren/ASC handled the final assembly and performance enhancements in Detroit, Michigan, giving the GNX its distinct character and significantly boosting its power and handling capabilities.

Performance Upgrades

The heart of the GNX was its turbocharged 3.8-liter V6 engine. While officially rated at 276 horsepower and 360 lb-ft of torque, many believe the actual output was significantly higher. McLaren/ASC upgraded the turbocharger, intercooler, and engine management system to achieve these impressive figures. The result was blistering acceleration, making it one of the fastest cars of its era. According to the Buick Grand National Wikipedia page, the GNX could achieve 0-60 mph times in the mid-4 second range, surpassing even some contemporary sports cars.

The Detroit Assembly Connection

The decision to have McLaren/ASC handle the final assembly and tuning in Detroit was critical. Detroit, the heart of the American automotive industry, possessed the expertise and infrastructure needed for such a specialized project. McLaren/ASC’s involvement ensured the GNX received the meticulous attention to detail required to maximize its performance potential. The Detroit assembly process contributed significantly to the GNX’s rarity and desirability, as only 547 were produced.

Exterior and Interior Enhancements

The GNX also featured unique exterior and interior styling cues. These included black mesh wheels, fender flares, and a torque arm suspension that improved handling and launch capability. Inside, the GNX featured special badging and gauges, differentiating it from the standard Grand National. These distinctive features, combined with its Detroit-tuned performance, made the GNX an instant collectible.
