the 800tt hennessey was tested again by car& driver i think in a road test for overall best tuned car of the year. this time however, obviously it was strapped with high performance rubber instead of slicks, which obviously demolishes any advantage teh viper had in a straight line. the viper actually is considerably slower than some weaker vipers because there is so much torque that it overhwhelmed the wheels. i think the quarter mile was almost 1.5 seconds lsower than the 10 second mark that was set earlier. anyways i would take the blitz over the hennessey because i love the grille and two cuz i corners better.
