It's about attitude..

First of all, we are talking about vipers now..not the 2003 which isn't even available. The current viper has 450hp. 0-60 3.9 1/4 in 12.2. The Z06 has 405hp and 0-60 in 4.0 1/4 in 12.6. There is your difference in power. Please do more research next time before commenting. Now, the difference is the hp/tq, as well as their hp/tq curves. But I am confused. Why is the viper still faster while weighing 300# more than the vette? Based on their power, and difference in weights, they should be about the same. And yes, I do know what I am talking about.. and stop racing on the street.
