You know Hennessey. The crazy Texans that believe simply bringing more firepower isn't enough, so they bring as much as is humanly possible? The guys behind that incredible 270 mph Venom GT? Some beautifully insane person just gave them the keys to an Escalade. It's called, simply enough, the HPE550 Supercharged Escalade, and it now puts out 557 hp. They spent so much time carefully engineering the supercharging system and tweaking the electronics that not only is driveability perfect, it comes with a three year, 36,000 mile warranty.
