I think this is a pretty obvious render, and I don't know how may folks are going to pay Hennessey 375k+ plus for a Silverado 6x6, but the company is saying zero to 60 will be in the 4 second range. Check out more info on this beast here.

I want to see some video of one of these babies in action... and I bet they'll deliver.
