5. Buick GNX
Nobody expected such a bold move from Buick. After all, Buick was a company for old people, producing cars without any excitement. And all of a sudden, there was a turbocharged V6 coupe that broke every classic muscle car mold and was faster than a Ferrari.
At that moment, the Buick GNX was the fastest-accelerating production model in the world. It featured the same 3.8-liter turbocharged V6 with 275 hp and 0 to 60 mph in 4.7 seconds. It’s too bad that Buick made just 547 examples of this extraordinarily influential car.
