Over nineteen feet in length and powered by a 6.2-liter, 380 hp V-8, the GMC Yukon Denali XL is already a master of excess. This vehicle, the Yukon Denali XL 2500 "Big Max" (meaning of course, big turned up to the maximum level) is the equivalent of a dentist performing a root canal with a jackhammer. Complete overkill. The already vicious V-8 gets a supercharger, and the stock 20-inch wheels give way to a shiny new set of 22s. A satellite TV system is mounted to the roof and can be watched on a number of monitors, including one massive 20-inch screen. These are all exciting add-ons, but we mostly want to hear more about the custom "chunky loop" carpeting. Sounds like some sort of snack.
