NO JOKE! That’s the first thing that comes to mind after watching this video of the new 580hp Camaro ZL1 going through testing at GM’s Milford Proving Grounds. This is not some hopped up dealer special, but a factory developed street/track weapon that has Ford’s Mustang Boss 302 dead in its sights. Now while not a true 24 hour endurance test (4 hours per day, for 6 days, in 40 minute sessions) it still pretty impressive to see how the engineers have tuned this new beast. Chevrolet’s new Traction Management system is the most impressive feature and allows the driver to opt for no-less then 5 different suspension settings. Everything from “Wet” mode to full-on “Race” mode is available and should keep the drivers well in the bounds of their ability. What’s going to be really interesting though is seeing how it stacks up against the soon-to-be replaced Corvette Z06. Right now though we’re just looking forward to the first tests and some hardcore numbers.
