GMC Yukon XL (2007)

GMC Yukon XL and Yukon XL Denali offer features such as power retractable running boards (available mid-year) and a power liftgate. Yukon XL models not equipped with the power liftgate feature an easy-to-operate liftgate that is specially designed with a micro-switch that assists the operator by using the mass of the tailgate to almost open or close itself once the liftgate is past the halfway-open position. An ergonomically designed, recessed cup with pull handle makes closing the liftgate an easy, one-handed operation.

Refined, spacious interiors

Yukon XL Interior space is roomier and has a spacious, refined environment, thanks to a premium two-tone color scheme and a lower-positioned instrument panel. New thinner, sculpted seat designs and detailed trim affirm Yukon XL's craftsmanship, which is bolstered by optional amenities such as heated seats for first- and second-row passengers. Also, the front seats offer more fore/aft and recline travel, and the second-row seats have an increased seatback recline angle for added comfort.

The upscale styling is complemented by new, softer and low-gloss materials for the instrument panel and other trim pieces. The harmonious color and grain of the materials were carefully selected to provide a premium feel as well as durability. Flush-mounted controls and radios, with almost imperceptible gaps, convey precision and integration. Chrome accents are used on instrument surrounds, vents and other trim.

Craftsmanship also is revealed in unexpected areas, such as distinctive sill plates with no visible hardware to greet occupants when the doors are opened, as well as no exposed fasteners or hardware on the pillars, seats or seat tracks. The seats have "close-outs" that surround the seat bottoms and seat tracks, creating a more finished appearance. Fasteners and hardware are covered, too, when the seats are folded.

As with the exterior, Yukon XL Denali is distinguished with exclusive, premium features, including sophisticated Nuance leather seating surfaces, unique center console, enhanced interior bright work and detailed, highly finished embossed sill plates that greet passengers when they open any of the Yukon XL Denali's doors. The unique center console has wood trim that conceals the lid and cupholder pockets, creating a more finished and refined appearance.

The Yukon XL family also offers a new, industry-exclusive power fold-and-tumble second-row seat feature that eases access to the third-row seat. The power fold-and-tumble second-row seats feature release buttons accessible by the driver or on the interior C-pillar to provide an easy, immediate release of the seat to create an access path to the third-row seat or cargo area.

Tri-Zone climate control is standard on all models. Automatic climate control is standard on Yukon XL Denali and Yukon XL SLT; it is available on Yukon XL SLE. A remote start system, standard on SLT/Denali models and available on SLE, allows the climate system to heat or cool the vehicle's interior. An enhanced array of audio, infotainment and safety options also is available and includes an available touch-screen navigation system, as well as a DVD system with larger flip-down screen positioned in front of the second-row seats.

There is more space inside the SUVs, as well. More fore/aft front seat travel provides the segment's leading legroom for front-seat passengers. Second-row seat legroom and knee room, and third-row seat headroom are increased over the previous models. The second- and third-row seats also have more shoulder room - a feat accomplished while also offering available roof-mounted head curtain side air bags. The third-row seats fold flat and are easily tumbled forward or removed for maximum cargo area. Also, the center console storage compartment, at 20.1 liters of capacity, is the segment's largest. The glove box offers 25 percent more storage space than previous models and features damped opening operation that bolsters quietness and refinement.

Responsive suspension, solid chassis

The '07 Yukon XL and Yukon XL Denali are built on GM's new full-size SUV platform, which incorporates features such as a new, fully boxed frame, coil-over-shock front suspension and rack-and-pinion steering. The frame supports wider front and rear tracks - approximately 3 inches (76.2 mm) wider in front and 1 inch (25.4 mm) wider in the rear - that enhance stability and driving confidence through a more secure road feel and a lower center of gravity.

The front suspension consists of an all-new coil-over-shock design that delivers linear, solid and unwavering ride and handling characteristics on all road surfaces. Also new is a rack-and-pinion steering system that provides precise and responsive control and enhanced on-center feel. A highly-refined five-link rear suspension provides superior isolation and ride, with larger, firmer brackets that also contribute to the vehicles' precise driving manners.

Larger, four-wheel disc brakes and an all-new ABS system ensure braking performance at the top of the segment. Larger vented front and rear brake rotors, 50-percent stiffer dual-piston calipers, longer-life brake pads and a new, robust tie-rod-type apply system contribute to enhanced pedal feel, reduced brake noise, predictable, linear brake response and shorter braking distances. A new, Bosch 8.0 next-generation four-channel ABS system also is standard. The ABS system works with the standard StabiliTrak electronic stability control system. In the new SUVs, StabiliTrak incorporates the first-time GM application of rollover mitigation, software algorithm technology that uses sensors to proactively predict vehicle "tip-up" and applies appropriate brake forces to prevent such events.

Enhanced driving control and ride smoothness is offered with the available Autoride real-time damping system (standard on Yukon XL Denali), which uses electronically controlled shock absorbers to make nearly instantaneous damping adjustments. The system "reads" the road and anticipates the best damping rates.

Seventeen-inch wheels are standard on Yukon XL, with 18-inch wheels standard on Yukon XL Denali. Twenty-inch wheels are available on Yukon XL and Yukon XL Denali. The wheels are designed with premium-appearance faces, including available chrome or polished finish. Yukon XL Denali wheels are exclusive. New tires are tailored to the vehicles to provide excellent balance of handling, quietness and safety.

New small-block V-8 family

A new Gen IV small-block V-8 family powers the new Yukon XL and Yukon XL Denali. Standard at start of production in Yukon XL models is a Vortec 5.3L V-8 with 320 horsepower (238 kw) and 335 lb.-ft. of torque (463 Nm), which offers Active Fuel Management displacement on demand fuel-saving technology. Active Fuel Management displacement on demand technology seamlessly switches between eight- and four-cylinder power to save fuel. Two versions of the Vortec 5.3L Gen IV V-8 - including an aluminum-block version that is standard on 4WD models - are compatible with E85 ethanol-based fuel, an alternative to gasoline. The engines can run on any combination of gasoline and/or E85 fuel.

Coming later in the year for is a powerful, new all-aluminum 6.0L V-8 with variable valve timing, as well as Active Fuel Management displacement on demand technology. The engine is rated at 355 horsepower (264 kw). VVT helps optimize camshaft timing to improve low-rpm torque and high-rpm horsepower. The system is enabled by a unique dual-equal cam phaser - the industry's first application of VVT on a mass-produced V-8 cam-in-block engine. The unique dual-equal phaser adjusts the camshaft timing at the same rate for both the intake and exhaust valves. A Hydra-Matic 4L70 electronically controlled four-speed automatic transmission is paired with the engine.

Heavy-duty models offer a 6.0L V-8 with VVT. It features an iron cylinder block and is rated at 350 horsepower (261 kw) and 360 lb.-ft. of torque (497 Nm). It is matched with a robust Hydra-Matic 4L80 four-speed automatic transmission.

The 6.2L engine of the Yukon XL Denali is all-new, too, with advanced technologies and lightweight materials, including VVT and an aluminum cylinder block, which helps the Yukon XL Denali delivering outstanding performance. The 6.2L engine is rated at 380 horsepower (283 kw), the most horsepower in its class, and 415 lb.-ft. of torque (564 Nm).

A new 6L80 six-speed is matched with the 6.2L engine. The six-speed automatic has a wide, 6.04:1 overall ratio - including two overdrive gears - that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter.

Safety and security

The '07 Yukon XL and Yukon XL Denali offer security in the form of a 360-degree perimeter safety system of occupant protection and crash avoidance technologies. New features include roof-mounted head curtain side air bags with rollover protection for all seating rows and front-seat safety belt pretensioners that are linked to the vehicle's sensing system to provide segment-exclusive deployment in rear-end crashes. These features are integrated into a stronger vehicle structure that is also designed for improved compatibility with other vehicles.

The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment. Sensors located at the front of the vehicle, in the side doors, and within the occupant compartment provide increased and more immediate crash detection. The vehicle's sensing system provides segment-exclusive capability to deploy front seat safety belt pretensioners during certain rear-end collisions, enhancing the belt system's ability to hold the occupants firmly in place.

The roof-mounted head curtain side air bag system incorporates one of the segment's first rollover indication sensors, which is located on the vehicle's center tunnel in the occupant compartment. The sensor monitors the vehicle's accelerations and roll rate. If these signals indicate an impending rollover, the roof-mounted head curtain side air bags deploy to provide an extra measure of occupant protection and containment. These rollover-capable head curtain side air bags stay inflated longer than air bags developed only for side impacts because rollover incidents can last longer. The deployment duration and other design features of the rollover capable air bags combine to provide increased occupant protection and the ability to help keep occupants inside the vehicle.

Crash avoidance is bolstered through enhanced design and driver control dynamics, such as wider front and rear tracks, as well as more responsive suspensions - including a new coil-over-shock front suspension design and new rack-and-pinion steering. The vehicles are built on a stronger and stiffer, fully-boxed frame that contributes to enhanced crash energy management. The front frame section has been designed to optimize crush progression resulting in improved energy absorption efficiency. The improved crush performance, enabled by hydroformed frame rails and efficient chassis component packaging, also comprehends design provisions for improved vehicle-to-vehicle compatibility in the event of a frontal impact with a smaller vehicle.

Additional safety features include:
+ Standard StabiliTrak stability control system with rollover mitigation technology
+ Standard dual-stage driver's front air bag
+ Standard dual-stage outboard-front passenger air bag with Passenger Sensing System
+ Available roof-mounted head curtain side air bags for all three seating rows (standard on Yukon XL Denali)
+ Standard front seat safety belt pretensioners with rear-impact deployment capability
+ Standard tire pressure monitoring system
+ Available rain-sensing wiper system (standard on Yukon XL Denali)
+ Available Ultrasonic Rear Parking Assist that can detect certain stationary objects in the rearward path of the vehicle and send an audible warning sound and display via three LEDs on the right D-pillar (standard on Yukon XL Denali)
+ Available rear-view camera system designed to provide the driver witha view of people or objects in the rearward path of the vehicle
+ Standard pull-up/push-down power window switches
+ Available voice-assisted navigation system.

All Yukon XL and Yukon XL Denali models come with the OnStar system (with a one-year Safe and Sound service plan). The system includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar Advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen (ability to locate stolen vehicles varies with conditions).
