Gnx

GNX is a designation used in multiple contexts, but it is most widely recognized as the badge of a Buick performance model from the 1980s. The Buick GNX refers to a limited-edition variant of the Buick Regal Grand National, produced in 1987 by Buick with involvement from ASC. The GNX featured a turbocharged 3.8-liter V6 engine with an upgraded intercooler, exhaust, and tuning that raised output above the standard Grand National. It also received suspension and brake upgrades, revised aerodynamics, and unique badging, all aimed at improving straight-line speed and overall handling.

The production run was limited to about 547 cars, making the GNX one of the rarest Buicks of its era. When new, it carried a price premium compared with the Grand National. Today, the GNX is highly sought after by collectors and is frequently cited as one of the defining American performance cars of the 1980s, notable for its blend of turbocharged power and Buick luxury.

Beyond the Buick model, GNX is an acronym used in various contexts, including company or product names, but it does not have a single universal meaning. In general references, though, GNX most often points to Buick's GNX within automotive history.
