16. Vector W8
The only American supercar on this list is the legendary Vector W8, a wedge-shaped, V8-powered monster they presented in 1990. It was an ambitious project by the Vector Aeromotive Corporation. They wanted to produce the most advanced supercar in the world by using aeronautical technology and materials in car production. The W8 had a space frame chassis with a Kevlar body and reinforced with a special kind of plastic.

Under the engine cover was a typical American powerhouse in the form of a Chevrolet small-block V8. They paired it with twin turbochargers to produce 625 HP, which was an impressive figure. The company claimed that at full boost, the 6.0-liter twin-turbo engine was capable of 1200 HP. However, they suggested drivers not use a full boost for extended periods of time, since it would affect the durability of the engine itself.
The Vector W2 cost $450,000, which was an enormous sum for the day. Despite being featured in numerous movies, TV shows, and computer games, it failed to reach sales success. When production ended in 1993, the Vector Aeromotive Company managed to produce only 22 examples of this fantastic American supercar.
