The time that Americans built cars that were only good in driving straight is far behind us. Meanwhile they're developing some amazing cars like this Chevrolet Camaro ZL1. Last week, a camouflaged copy was spotted on the Nürburgring during some tests. Not only the sound is impressive, the car also has a great speed through Karussell. We expect that the ZL1 will produce over 600 hp, sounds like a great toy!
