1987 Buick GNX
The Buick GNX was a car that completely changed the game in the 1980s. It utilized a turbocharged V6 engine instead of relying on the traditional V8. GM was experimenting with turbo-powered cars a lot during this era. The GNX had a number of unique attributes that made it stand out from the crowd, but the performance was the most important aspect (via Trust Auto).

The GNX was the basis for the GMC Typhoon and the GMC Syclone as well. All three cars were notable for their build quality and reliability. Buick had a knack for building unique cars around this time period and the GNX was evidence of that. The car performed well in every aspect and introduced the world to the power of the turbocharged V6.
