2013 Shelby GT500 gets 662 HP - beats Viper & Vette

Are you kidding? The ford will keep up with the viper....if it ever hooks up. "Power without control is nothing" as my uncle used to say. And the Shelbys have never had control when it comes to putting the power down, except for the lower powered ones. And I'm pretty sure that the 2 keys are specific to the Boss 302 and 302 Laguna Seca editions of the mustang.

As to the comment on the hemi not keeping up. The new Challenger has an engine 36 CI smaller than the LS7. Yet it still only makes 30 less horsepower and the same amount of torque as that slightly larger motor. I think it's keeping up just fine. What they need to do is loose about 400 lbs. Which will be hard, but it's a necessity. They MUST do it. Handling, the Vette vs Viper the ZR1 and the ACR are about the same on the road courses. Right now I think the Viper is at 7:22 around the Nurburgring and the Vette is at 7:26. So yeah, the Viper leads in just about anything and if the conversations around here have said anything, it'll begin killing the C7 Vette in sales when the new generations of each are released as the viper has an interior light years ahead of the Vette.
