2006 GMC Yukon XL Model Update

Yukon Territory

The large and boxy GMC Yukon XL rolls on with only minor changes until a new version hits the road in early 2006.

The GMC Yukon XL is a stretched version of the Yukon and equivalent to the Chevrolet Suburban, with which it shares chassis and powertrains. It continues with only minor changes for 2006, as GM rushes a redesigned replacement for introduction in the first quarter of 2006 as a ’07 model.

Though an all-new version of any vehicle is appealing in its novelty, there's something to be said for buying the last version of an outgoing generation (like the 2006 Yukon XL) because it benefits from updates, improvements and refinement over the vehicle's lifecycle. That said, there's no guarantee 2006 Yukon XLs will be on dealer lots for much longer as 2007 models make their debut in showrooms.

For 2006, the Yukon XL can be ordered with a flex-fuel version of the vehicle’s standard 5.3-liter V8 engine. It can operate on fuel that contains up to 85 percent ethanol mixed with gasoline. Ethanol is a renewable fuel made from waste products from crops, like corn husks. It emits fewer exhaust emissions than gasoline, but can emit more evaporative emissions.

Also for 2006, a tire-pressure monitoring system is made standard on all models, and power-adjustable pedals and extendable, power-adjustable camper mirrors are new options.

While the Yukon XL is one of the largest and heaviest vehicles this side of a tractor trailer, with the ability to carry as many as nine passengers in three rows of seats, it comes amply powered by a selection of hearty V8 engines. The base 5.3-liter V8 should be sufficient for most buyers and does a nice job of moving the XL’s mass up to highway speed.

Those looking for a vehicle that can tow or haul the largest of loads can choose either a 300-hp 6.0-liter V8 (its optional on 1500 models and comes standard with 2500 versions) or a 340-hp 8.1-liter V8 (only in the 2500) that cranks out 455-pounds-feet of torque for heavy-duty hauling and towing. The maximum tow rating with this engine is a whopping 12,000 pounds. A smooth-shifting four-speed automatic gearbox comes with a tow/haul mode to optimize shift patterns for pulling power.

A standard Premium Smooth Ride package offers decent ride comfort, while an optional Autoride suspension includes variable shocks and rear-load leveling to further refine the ride. A Z-71 off-road performance package is available for those who want to go far off road, but its stiffer suspension and trail-ready tires conspire to make a rougher highway ride. Standard four-wheel-disc antilock brakes with Dynamic Rear Proportioning are standard, and Hydroboost braking is added to provide reserve-braking power on demand — a handy feature when towing or hauling heavy loads. StabiliTrak stability control is standard across the line.

Yukon XLs come well equipped with a long list of standard features, including dual-zone climate control, a CD stereo, the OnStar communications/safety system and a rear liftgate with flip-up rear glass. Leather captain’s chairs, a rear-seat DVD entertainment array, XM satellite radio and a touch-screen navigation system are among the myriad options.
