From the street, the GMC Yukons customized by Dillon Aero look like standard-issue SUVs. But behind the tinted windows lurks a fire-spitting dragon: a Dillon Aero M134D Gatling minigun. Designed for VIP escort, the Yukons are outfitted with a roll cage, steel-plate armor and puncture-proof fuel cells and tires. And though weighing around 9000 pounds, the vehicles can exceed speeds of 100 mph
(forthcoming supercharged models should be able to go even faster).
