GMCYukon XL 1999 - 2006

　　GMC introduced the Yukon XL on the extended chassis from the GMC Yukon, or the Chevrolet Tahoe, if you want, but it was more luxurious than both of them.

　　A longer wheelbase doesn't only make room for three rows of seats. It also increases the legroom for the rear passengers. With its huge experience in building SUVs, GMC tried to make the Yukon XL better for its occupants, even if that was translated into higher fuel consumption.

　　From the outside, the Yukon XL offered the same front fascia as its shorter cousin, with chromed grille and headlights surroundings. The longer rear windows were evident from its sides, and so were the specific chromed alloy wheels. Since it was based on the same chassis as the GMC Sierra pickup, the Yukon XL stood on the same size wheels.

　　Inside, there were numerous upgrades when compared to the standard Yukon. The car was designed to work for official agencies, and it was almost a luxury vehicle. GMC priced-it just below the recently introduced Cadillac Escalade. Inside, the big SUV was fitted as a standard in a seven-seat configuration.

　　Under the hood, GMC installed the LM7 engine on the standard version. The full-option model featured a 6.0-liter V-8 engine. For special applications and law-enforcement agencies, GMC offered an 8.1-liter V-8 unit. The four-speed electronically controlled.
