1984 Buick Grand National
The Buick Grand National was one of the turbocharged cars that changed the game. Everything about it was next level, from the design to the engine, and it changed the way that we thought about turbocharged cars. The noteworthy build quality was based on the GM G-Body platform, and it changed the way that the car was positioned. Instead of focusing on a big V8 engine, the Grand National utilized a turbo-powered one (via Car & Driver).
Every inch of the Grand National was a great example of GM engineering at its finest. The beautiful exterior and the noteworthy interior made the Grand National look a lot different than any other G-Body car. Few cars have changed the face of turbo-powered rides as the Grand National did in its prime and every other GM turbo that came after it.
