most powerful cars on the market

As part of the famous Dodge Viper line of vehicles, SRT Viper is a powerful machine with 640 horsepower and the top speed of 206 miles per hour. You can buy it for $459,000; however, there is a limited edition package called the Time Attack package that would cost you additional $16,000. The package adds another 200 pounds of downforce, making the top speed a little lower 193 miles per hour, but making the vehicle more aerodynamic than before. An interesting thing to note is that it set the production car lap record in 2013, with 1:33:62.
