In the last couple days, it's been announced that the world-famous Hennessey Performance will be partnering up with AutoNation Dealerships to bring you upgrade packages for your 2015 Chevy Silverado and Corvette Stingray. Options for the Silverado include two power packages putting down either 557whp & 542 ft/lbs or 605whp & 621 ft/lbs. In their promotional pictures and videos, the Silverado is sporting some 20" Standards. We dig it!
