USA! USA! The only American entry on this list of top speeds is of course the Corvette ZR1, one of the most powerful production cars available, making more than 600 horsepower. In a land of Porsches and Mercedes-Benzes and Audi R8s, the 'Vette we take for granted is a special kind of speed demon in Germany. Granted, the ZR1 is a special kind of speed demon no matter where it is.
In 2008, a team from the Dutch autoblog (ABHD) took one of the first ZR1s to hit Europe on the autobahn for a little high-speed test. Thanks to some pesky traffic and a few work zones (it's probably safe to say those guys were happy they wore helmets that day), the team only managed to get the ZR1 up to 192 miles per hour (309 kilometers per hour). "Only" 192 miles per hour because the car is engineered to hit 205 miles per hour (329.9 kilometers per hour). Even so, I doubt the guys driving the car were sad to be 13 miles per hour below the car's full capability. How sad would you be at 192 miles per hour? You can check out the video, too.
