No it isn't. The GNX (only 547 of them made) had some obvious differances on the exterior as well as engine mods (which weren't really "engine" mods, rather bolt ons). Right above the Grand National logo on the fender they sported the infamous "Buick Louvers" to aid in keeping the relay center cooled, as well as to help lower underhood temperatures. They also bore a set of fender flares over differant wheels. I personally didn't like the exterior "upgrades" of the GNX. I felt they were gaudy. But...
The GNX used a ceramic impeller turbo. this had 2 distinct advantages. 1 was heat disapation (the cooler the charge the more dense it is) and the other was spooling speed (the ceramic was lighter). The visual underhood differance was the vented turbo cover expressing "GNX". Also, they used a larger intercooler to aid in air charge temperature reduction.
Then there was the McLaren Suspension. It consisted of a stiffening frame the bolted to the trans and rear end, reducing roll and aiding in traction/ overall handeling.
And of course, the KILLER GNX dash. I want one, but the unit is so expensive.
